SAFETY

General Safety Instructions and Practices

Asafe and careful operator is the best operator. Safety is of primary importance to the manufac-

turer and should be to the owner/operator. Most accidents can be avoided by being aware of

your equipment, your surroundings, and observing certain precautions. The first section of this

manual includes a list of Safety Messages that, if followed, will help protect the operator and

bystanders from injury or death. Read and understand these Safety Messages before assem-

bling, operating or servicing this implement. This equipment should only be operated by those

persons who have read the Manual, who are responsible and trained, and who know how to do

so safely and responsibly.

The Safety Alert Symbol combined with a Signal Word, as seen below, is used throughout this

manual and on decals which are attached to the equipment. The Safety Alert Symbol means:

“ATTENTION! BECOME ALERT! YOUR SAFETY IS INVOLVED!” The Symbol and Signal

Word are intended to warn the owner/operator of impending hazards and the degree of possible

injury faced when operating this equipment..

Practice all usual and customary safe working precautions and

above all---remember safety is up to YOU. Only YOU can prevent

serious injury or death from unsafe practices.

CAUTION!

The lowest level of Safety Message; warns of possible injury. Decals

located on the Equipment with this Signal Word are Black and Yellow.

WARNING!

DANGER!

Serious injury or possible death! Decals are Black and Orange.

Imminent death/critical injury. Decals are Red and White.

Operator Safety Instructions and Practices

Never operate the Tractor or Implement until you have read and

DANGER!

completely understand this Manual, the Tractor Operator’s Manual,

andeachoftheSafetyMessagesfoundintheManualorontheTractor

and Implement. Learn how to stop the tractor engine suddenly in an

emergency. Never allow inexperienced or untrained personnel too

operate the Tractor and Implement without supervision. Make sure

the operator has fully read and understood the manuals prior to

operation. (SG-4)

WARNING!

The operator and all support personnel should wear hard hats,

safety shoes, safety glasses, and proper hearing protection at all

times for protection from injury including injury from items thrown by

the equipment.

(SG-16)

PROLONGED EXPOSURE TO LOUD NOISE MAY CAUSE PER-

MANENT HEARING LOSS! Tractors with or without an Implement

attached can often be noisy enough to cause permanent hearing

loss. We recommend that you always wear hearing protection if the

noise in the Operator’s position exceeds 80db. Noise over 85db

over an extended period of time will cause severe hearing loss.

Noise over 90db adjacent to the Operator over an extended period of

time will cause permanent or total hearing loss. Note: Hearing loss

from loud noise [from tractors, chain saws, radios, and other such

sources close to the ear] is cumulative over a lifetime without hope

of natural recovery. (SG-I7)

Rotary Mowers are capable under adverse conditions of throwing

objects for great distances

(100 yards or more) and causing

serious injury or death. Follow safety messages carefully.

STOP MOWING IF PASSERSBY ARE WITHIN 100 YARDS UN-

LESS:

-Front and Rear Deflectors are installed and in good,

working condition;

-Mower Head is running close to and parallel to the ground

without exposed Blades;

-Passersby are outside the existing thrown-object zone;

-All areas have been thoroughly inspected and all foreign

material such as rocks, cans, glass, and general debris

has been removed.

Where there are grass and weeds high enough to hide debris

that could be struck by the blades, the area should be: in-

spected and large debris removed, mowed at an intermediate

height, inspected closely with any remaining debris removed,

and mowed again at desired final height. ^(SBM-1)

NOTE:

Use extreme caution when raising the Mower head. Stop the Blades

from turning when the Mower Head is raised and passersby are within

100 yards. Raising the Mower head exposes the Cutting Blades

which creates a potentially serious hazard and can cause serious

SAFETY

Transporting Safety Instructions and Practices

Be particularly careful when transporting the Implement with the Tractor.

WARNING!

Turn curves or go up hills only at a low speed and using a gradual

steering angle. Rear mounted implements move the center of gravity to

the rear and remove weight from the front wheels. Make certain, by

adding front ballast, that at least 20% of the tractor’s weight is on the

front wheels to prevent rearing up, loss of steering control or Tractor tip-

over. Slow down on rough or uneven surfaces to prevent loss of

steering control which could result in property damage or possible injury.

Do not transport unless 3-Point lift lever is fully raised and in the latched

transport position. Dropping implement in transport can cause serious

damage to the tractor and/or Implement and possibly cause the operator

or others to be injured or killed. ^(S3PT-2)

Allow sufficient clearance for the Implement to swing outward while turning. Implements

carried behind the Tractor will swing outside the tire path when making turns. Contacting a

solid object while turning will cause equipment damage and possible injury. ^(S3PT-20)

WARNING!

DANGER!

Be particularly careful in transport. The Mower has raised the center

WARNING!

Make certain that the “Slow Moving Vehicle” (SMV) sign is installed in

such a way as to be clearly visible and legible. When transporting the

EquipmentusetheTractorflashingwarninglightsandfollowalllocaltraffic

regulations. ^(SG-6)

Transport only at safe speeds. Serious accidents and injuries can result

from operating this equipment at unsafe speeds. Understand the Tractor

and Implement and how it handles before transporting on streets and

highways. Make sure the Tractor steering and brakes are in good condition

and operate properly.

Before transporting the Tractor and Implement, determine the safe transport

speeds for you and the equipment. Make sure you abide by the following

rules:

1. Test the tractor at a slow speed and increase the speed slowly.

Apply the Brakes smoothly to determine the stopping

characteristics of the Tractor and Implement. As you increase

the speed of the Tractor the stopping distance increases.

Determine the maximum safe transport speed for you and this

Equipment.

2. Test the equipment at a slow speed in turns. Increase the speed

through the turn only after you determine that it is safe to operate

at a higher speed. Use extreme care and reduce your speed

when turning sharply to prevent the tractor and implement from

turning over. Determine the maximum safe turning speed for you

and this equipment before operating on roads or uneven ground.

3. Only transport the Tractor and Implement at the speeds that you

have determined are safe and which allow you to properly control

the equipment.

Be aware of the operating conditions. Do not operate the Tractor with

weak or faulty brakes. When operating down a hill or on wet or rain slick

roads, the braking distance increases: use extreme care and reduce your

speed. When operating in traffic always use the Tractor’s flashing warning

lights and reduce your speed. Be aware of traffic around you and watch

out for the other guy. (SG-19)

ASSEMBLY

GENERAL

The Rhino 1348, 1548, and 1948 differ slightly in some areas. Notes have been provided for these differ-

ences, be sure to refer to the proper note for your machine.

TRACTOR REQUIREMENTS

Before preparing the tractor for the machine make sure that specifications of the tractor meet the re-

quirements listed below.

A. 6 spline P.T.O. of 1-3/8" dia.

B. A P.T.O. output of 540 rev/min.

C. A top link is available.

D. As a guide for suitable tractor size the ballasted weight of tractor should exceed 2750 kg (6050 lbs)

E. Adequate ballast should be added to the rear wheel opposite to the arms and front of the tractor to

ensure stability. The amount will vary depending on type of tractor used and prevailing conditions.

MACHINE PREPARATION

The machine will normally be delivered with the arms fully assembled to the mainframe, but with the

mower head detached.

The lifting points FIGURE 3-1 (A), 3-1 (B) and FIGURE 3-2 (A) are for machines without the mower head

attached or hydraulic oil. When lifting machine in anything other than this conditions extreme care should

be exercised as the center of gravity may change. Only personnel experienced in lift and hoist operation

should attempt it. Note the Lifting Point and transport straps / retaining chain differ between the 1348/

1548 and the 1948 (see FIGURE 3-1).

A. Position the machine on a flat hard surface.

B. If not already fitted, lift the machine and fit the parking stands which will be found stored under the

mainframe.

C. Remove the transport straps 3-1 (C), 3-1 (D), identified by the red panel.

Remove the retaining chain and greasing setscrew from transport plate and fit into tapped hole of first/

second arm pin and tighten up.

NOTE: The second arm on the RBF-12 is required to be moved from on top the first arm to below the first

arm and the second ram re-fitted to it.

ASSEMBLY

The RBF-12C is supported on the three point linkage of the tractor and its height set by chain tensioners.

Refer to FIGURE 3-3

A. Carefully reverse the tractor so that the ball joint on the lower arm C lines up with the clevis D in the

stabilizer bracket/breakout link.

B. Adjust the height hydraulically until the left hand link arm can be positioned in the clevis (D) and

secured with hand pin (E).

C. Adjust the right hand lift arm leveling screw until this arm can be secured to the clevis of the stabi-

lizer bracket with the hand pin provided.

D. Attach top link bracket. Two types of chain bracket are supplied: a single bracket that locates in a

lower alternative top link position, or a pair of plates to fit either side of the top link on the same pin.

E. Fit whichever type is most suitable and thread the chain through the keyhole-shaped hole(s), so that

the two equal length of chain are suspended from the bracket(s).

F. Lift the machine until the tractor and machine PTO are in line. Adjust the right arm and top link until

the machine is square with the tractor.

G. Thread each end of the chain through the keyhole in the lower link stabilizer bracket.

H. Lock the chain in the slot of the stabilizer bracket, taking up the slack in the chain between the top

link and the bracket, and ensuring the lengths of the chain on each side are the same.

I. Lower the machine carefully, ensure that tension on each chain is taken up evenly. The chain attach-

ment brackets are designed to flex and to take up minor irregularities.

J. Clip the 'loose' ends of the chain G to the taut chain as far as possible to lock it positively in the

bracket keyholes.

K. Fit the tractor external check chains to the lift arms and adjust until there is no sideways movement.

A. The machine is supported on the three-point linkage of the tractor, together with a rigid frame be-

tween the mainframe and top link attachment of the tractor . See FIGURE 3-4.

ASSEMBLY

B. Prepare the mower by using the top link to join the mower's upper hitch point to the A frame upper

clevis.

C. Using the lower hitch pins, fix the A frame tube ends in the inner clevis of each lower hitch point. At

this stage the lower hitch pins should not protrude into the outer lower hitch clevis.

D. Carefully reverse the tractor so that the ball joint on the tractor linkage line up with the clevis on the

mainframe. Connect the mower with hitch pins that are retaining the A frame. By this time the hitch pin

should pass through both A frame tubes and lift arm ball ends.

E. Connect the upper hitch point of the A frame to the tractor upper hitch point, adjusting the top link as

necessary.

F. Lift machine to its working height, ensuring that the machine is level by adjusting the tractor linkage

to suit.

G. Fit the top strut and the top link bracket, connecting the struts together with the two bolts provided. It

may be necessary on certain tractors to twist the struts to fit.O

H. The A frame is now a rigid unit and the tractor lift arms can be lowered by removing the weight from

the tractor hydraulics.

NOTE: It is important that at this stage the tractor lower link check chains are fully tightened to remove

all horizontal motion from the tractor lower links.

I. Remove front and rear stands from the mainframe and store underneath the mainframe. (See Gen-

eral Arrangement.)

J. Adjust the top link until the machine is square with the tractor.

FITTING PTO

NOTE: The tank must be filled with the correct grade of oil before the PTO is fitted. See Maintenance

Section.

Due to many different makes and sizes of tractor to which Servis mowers can be fitted, a nominal length

of PTO shaft is supplied with the machine. In some cases it may be found that this PTO shaft is too long

and will have to be shortened.

NOTE: Minimum engagement of PTO square drive is 100mm (4 in) and 150mm (6 in) for the Lemon

Tube Type in the working position. This measurement must be taken into account when shortening the

PTO shaft.

Before fitting PTO shaft to tractor grease the sliding drive shafts and bearing units.

Fit PTO to tractor ensuring locking pin on the splined coupling is fully engaged.

ASSEMBLY

FITTING CONTROLS

The position of the lever unit inside the tractor cab depends largely upon the route of the cables between

unit and control valve.

The control valve is mounted on the front face of the oil tank.

The cable normally can be routed through the rear cab window and should be as free of bends as

possible. DO NOT PINCH CABLE IN CLOSED WINDOW.

NOTE: Avoid sharp bends. The rotor control cable must not have a bend of less than 150mm (6 in)

radius.

If the tractor cab has special apertures for cables the lever unit should be through them before they are

attached to the tractor cab.

Follow instructions below for fitting lever unit.

A. Pass lever unit and cable through suitable aperture in rear of tractor cab.

NOTE: It is essential not to drill mounting holes through any structural member of the safety cab.

B. Mount the unit securely on to the mounting bracket with bolts provided.

C. Finally, check levers for smooth operation in both directions. If any stiffness is felt or if levers do not

return to center, check cable route for sharp bends.

NOTE: Whenever the machine is removed and the tractor is operated without the control valve unit in

place, fit rubber beading (contained in the cab fitting kit) to the edge of the console mounting bracket to

prevent risk of injury.

LEVER UNIT

A. Adjustment is provided at the cable attachment to the control valve.

CONNECTING THE MOTOR

The connection of the hoses to the motor will determine the direction of rotation of the rotor shaft. As

reverse rotation is standard on the machine, then the following instructions will apply to reverse rotation.

For forward rotation the pipe connections on the motor are interchanged.

A. Locate the relief valve at the pump outlet.

B. Connect hose attached to port marked 'P' for pressure, to the bottom rear fitting on motor and tighten.

C. Connect hose attached to port marked 'T' for tank, to the top fitting on motor and tighten.

D. For forward rotation interchange these hoses.(Same as tractor tires)

NOTE: When fitting Cowl Bracket in different positions on the cowl rear beam it is important that the

motor hose cannot be caught up between the Arm and rear of the Cowl. It may be necessary to reposi-

tion the hose in hose clamps on the second arm.

MECHANICAL BREAKOUT

The RBF-12C is equiped with a mechanical breakout, which is fitted at the bottom of the kingpost attach-

ment point in the mainframe. This will reduce the risk of damage if an obstruction is encountered during

work. This breakout mechanism is pre-set at the factory and should not need any adjustment. If it is ever

dismantled it is important that the disc springs are replaced in the correct sequence.

HOSE LAYOUT

It is important that hoses are fitted correctly. To ensure that there are no kinks, sharp bends and that

the hoses do not chafe against sharp edges, the following layout should be used as a guide.

Twists

Hoses should never be twisted or kinked. On most hoses there is a line which runs the full length of the

hose acting as a useful guide (see FIGURE 3-8). If there is no guideline running along the hose follow

the fitting instructions below.

ASSEMBLY

INITIAL RUN

A. Check that the motor hoses are connected together.

B. Run tractor engine at idle speed and engage PTO drive.

C. Increase PTO speed gradually up to 360 rev/min.

D. The pump will start operating during run-up. Flexing of the motor hoses and turbulence of the oil

tank can be observed.

E. When pump is operating run system at 360 rev/min PTO speed for 10 minutes.

F. Check oil level. The oil level is correct when visible in the bottom of the filler assembly strainer.

BLEEDING RAMS

The ram cylinders at first will be full of air, therefore it may take some time for the cylinders to move after

the control levers have been operated. Ensure sufficient space is available to allow for any unexpected

movement of the arms.

Bleeding the First Ram

Due to the fact that the first arm can move past the vertical (overcenter) when fully raised, a restrictor

may be fitted in the first ram hydraulic system to give a slow, controlled movement of the arm past

center. It is essential that the first ram is fully bled to prevent fall back to the arm when the arms are

stretched out and taken past vertical.

NOTE: The following instructions must be carried out before any attempt is made to raise more than one

arm at a time.

A. Engage PTO drive with tractor engine at idle speed.

B. Increase PTO speed to 360-400 rev/min.

C. Fully retract second cylinder.

D. Fully retract the first cylinder.

E. Slacken hose connection at the bottom of the first cylinder.

G. Continue the bleeding until only clean, bubble-free oil is escaping from the fitting. Tighten fitting.

H. Open and close all cylinders to expel the air.

I. Check the oil level in the tank/tractor hydraulic oil reservoir and top up if necessary.

J. Check all hydraulic connections in the cylinder circuit for tightness.

WARNING! Do not raise more than one arm at a time until cylinders are completely free of air. Unex-

pected movement of the arms can be dangerous.

TIGER REAR MOUNT BOOM

OPERATION INSTRUCTIONS

TIGER Booms are manufactured with quality material by skilled workers. The Boom is designed to attach to a

tractor and operate the flail head to cut grass and trim hedges. The boom and head are equipped with safety

warning decals, protective deflectors, shields, and other safety features to provide operator and passerby protection,

however, no shielding is 100% accurate. ALL safety equipment and safety warning decals must be maintained on

the unit in good operational condition at all times.

It is the operator’s responsibility to be knowledgeable of all potential operating hazards and to take every reasonable

precaution to ensure oneself, others, animals, and property are not injured or damaged by the boom unit, tractor

or a thrown object. Do not operate the boom and attached head if bystanders, passersby, pets or livestock are

within 300 feet of the unit.

This section of the Operator’s Manual is designed to familiarize, instruct, and educate operators to the safe and

proper use of the boom and attached head. Pictures contained in this section are intended to be used as a visual

aid to assist in explaining the operation of a Boom and are not specific to Boom. Some pictures may show shields

removed to enhance visual clarity. NEVER operate the boom unit without all safety equipment in place and in good

operational condition. The operator must be familiar with the boom unit and tractor operation and all safety

practices before beginning operation. Proper operation, as detailed in this manual, will help ensure years of safe

OPERATION

2.4 Tractor Ballast

To ensure tractor stability when operating on flat surfaces the left rear tractor tire MUST exert a minimum down

force (weight) of 1500 lbs. on the ground when the tractor is on level ground, its boom is fully extended and the

mower head is horizontal and two feet above the ground. For units which have the ability to operate on either side

of the tractor, these requirements must also be met for the right side tire when the boom is extended to the left side

as described above. A tractor that does not meet this criteria is DANGEROUS and should not be operated as

upset of the unit can occur resulting in possible serious injury and property damage. NOTE: All factory mounted

units are tested and meet the ballast requirement before shipment; further testing is not required unless the unit is

operated in a manner other than what is considered standard operating conditions.

For additional information on properly ballasting the tractor, refer toAlamo Industrial Tractor and Mower Stability

Pamphlet P/N #02959010.

Each Rear Wheel must have a minimum of 1500 pound contact with

the surface to prevent lateral instability and possible tip-over which

could result in serious bodily injury or even death. Widen the wheel

tread and add weights if needed. Refer to the mounting instructions

or call Customer Service if you need assistance with Counterweight

Procedure. (SBM-11)

DANGER!

If the unit is operated on slopes greater than 5°,

additional counterweight will be required. Operation of

the unit on slopes greater than 11° is not recommended

under any circumstances. On a tractor with a 96”

outside to outside tire spread, a 11° slope occurs when

one rear tractor tire is about 8” lower than the other

rear tire.

Do not operate the unit under any circumstance if the slope is 10° or greater.

WARNING!

3. GETTING ON AND OFF THE TRACTOR

The operator must read and completely understand this manual and the tractor operator’s manual before starting

any boom mower operation. If any part of either manual is not completely understood, consult an authorized

dealer for a complete explanation. If the operator of the equipment can not read the manuals for themselves, it is

OPERATION

8 DRIVING THE TRACTOR AND MOWER

Safe tractor transport requires the operator to possess a thorough knowledge of the model being operated and

precautions to take while driving with an attached implement. Ensure the tractor has the capacity to handle the

weight of the boom and the tractor operating controls are set for safe transport. To ensure safety while driving the

tractor with a boom, review the following.

Read all safety instructions. Decals on the Machete Boom warn you of particular and multiple hazards. Some

decals are attached close to part of the Machete Boom where there is a possible hazard. Read and make sure

you understand the safety messages before you operate the implement. Keep all decals clean and readable.

Replace lost or damaged decals, refer to safety section for more information.

Power for operating the mower is supplied from the tractor PTO. Refer to your tractor manual instructions for

engaging and disengaging the PTO. Start the tractor and bring the engine speed up to normal operating speed of

540 PTO RPM. Always engage the PTO at low engine RPM and run the mower for a short period until all air is

removed from the hoses. Keep all person's well clear of mower since blades can throw objects with great velocity

for a considerable distance! KEEP CLEAR!

Transport only at safe speeds. Serious accidents and injuries can result

from operating this equipment at unsafe speeds. Understand the Tractor

and Implement and how it handles before transporting on streets and

highways. Make sure the Tractor steering and brakes are in good condi-

tion and operate properly.

WARNING!

Before transporting the Tractor and Implement, determine the safe

transport speeds for you and the equipment. Make sure you abide

by the following rules:

1. Test the tractor at a slow speed and increase the speed slowly.

Apply the Brakes smoothly to determine the stopping

characteristics of the Tractor and Implement.

As you increase the speed of the Tractor the stopping distance

increases. Determine the maximum safe transport speed for

you and this Equipment.

Test the equipment at a slow speed in turns. Increase the speed

through the turn only after you determine that it is safe to operate

at a higher speed. Use extreme care and reduce your speed when

turning sharply to prevent the tractor and implement from turning

over. Determine the maximum safe turning speed for you and this equip-

ment before operating on roads or uneven ground.

Only transport the Tractor and Implement at the speeds that you

have determined are safe and which allow you to properly control

the equipment.

Be aware of the operating conditions. Do not operate the Tractor with weak

or faulty brakes. When operating down a hill or on wet or rain slick roads, the

braking distance increases: use extreme care and reduce your speed. When

operating in traffic always use the Tractor’s flashing warning lights and re-

duce your speed. Be aware of traffic around you and watch out for the other

guy. (SG-19)

transmission in neutral. Starting a tractor in gear can result in injury or

death. Read the Tractor operators manual for proper starting

instructions. ^(SG-13)

8.2 Brake and Differential Lock Setting

Make sure the tractor brakes are in good operating

condition. Tractor brakes can be set to operate

independently allowing single rear wheel braking action

or locked together to provide simultaneous rear wheel

braking. FOR MOST DRIVING AND MOWING

CONDITIONS, THE BRAKE PEDALS SHOULD BE

LOCKED TOGETHER TO PROVIDE THE MOST

EFFECTIVE BRAKINGACTION.

WARNING!

Be aware of the operating conditions. Do not operate the Tractor with weak or faulty

brakes. When operating down a hill or on wet or rain slick roads, the braking distance

increases; use extreme care and reduce your speed in these conditions. When operating

in traffic, always use the Tractor’s flashing warning lights and reduce your speed. Be

aware of traffic around you and watch out for the other guy.

Always disengage the tractor differential lock when turning. When engaged the differential lock will prevent or limit

the tractor from turning. During normal cutting conditions, locking the differential provides no benefit and should

not be used.

8.3 Driving the Tractor and Mower

Inspect the area to be mowed before beginning operation. Identify any drop-offs, slopes, holes, hidden obstructions

or similar obstacle that could cause the tractor to loose stability and potential roll-over. Mark and avoid the item or

the entire area.

Start off driving at a slow speed and gradually increase your speed while maintaining complete control of the

tractor. Never operate the tractor at speeds that cannot be safely handled or which will prevent the operator from

stopping quickly during an emergency. If the power steering or engine ceases operating, stop the tractor immediately

as the tractor will be difficult to control.

Perform turns with the tractor and mower at slow speeds

to determine how the tractor with and attached

implement handles a turn. Determine the safe speed

to maintain proper control of the tractor when making

turns. When turning with the implement the overall

working length and width of the unit is increased. Allow

additional clearance for the unit when turning or when

passing large obstructions.

OPERATION

9. OPERATING THE BOOM UNITANDATTACHED HEAD

THE OPERATOR MUST COMPLETELY UNDERSTAND HOW TO OPERATE THE TRACTOR AND MOWER

AND ALL CONTROLS BEFORE ATTEMPTING TO MOW. The operator must read and understand the Safety

and Operation Sections of this manual and the tractor operator’s manuals. These manuals must be read and

explained to any operator who cannot read. Never allow someone to operate the unit without complete operating

instructions.

To ensure safety to the operator, bystanders, and equipment and before starting any mowing operation. The

operator must become familiar with the area to be mowed, and any obstacles and hazards contained within.

Special attention should be paid to foreign debris, overhead obstructions, rough terrain, steep slopes, passersby

and animals in the area.

Only operate the mower head from the tractor operator’s seat with the seatbelt securely fastened. Only operate a

boom and equipped head on cab-ed tractor that is equipped with a Lexan^®protected right side window or a non-

cab-ed tractor equipped with a ROPS and operator safety screen.

Avoid operating in the reverse direction when possible. In situations where the boom and mower must be backed

to access areas to be cut, make sure there are no persons or other foreign debris behind the tractor. When

backing, operate the tractor at a much reduced ground speed to ensure complete control of the unit is maintained.

WARNING! Do not mow with two machines in the same area except with Cab tractors with the windows closed.

(SGM-11)

DANGER!

Mow only in conditions where you have clear visibility in daylight or with adequate artificial lighting.

Never mow in darkness or foggy conditions where you cannot clearly see at least 100 yards in front

and to the sides of the Tractor and Mower. Make sure that you can clearly see and identify

passersby, steep slopes, ditches, drop-offs, overhead obstructions, power lines, debris and foreign

objects. If you are unable to clearly see this type of item discontinue mowing. (SGM-1)

DANGER!

Avoid mowing in reverse direction when possible. Check to make sure there are no persons behind

the Mower and use extreme care when mowing in reverse. Mow only at a slow ground speed

where you can safely operate and control the Tractor and Mower. Never mow an area in the reverse

direction that you have not inspected and removed debris or foreign material. ^(SGM-8)

WARNING!

Never operate the mower head tilted down where the operator can see the blades of the mower.

The blade could throw an object toward the operator causing serious injury or death. Never operate

the mower without an Operator Protective Structure.Always were safety glasses and a hard hat.

OPERATION

9.1 Foreign Debris Hazards / Overhead Obstructions

An area to be cut must first be inspected for objects that could be thrown or that could damage the machine.

Walk through the area looking for fences, boulder, rocks, culverts, stumps or metal objects. Mark the

inspected area with flags. If the area is dense and cannot be walked thoroughly it may be necessary to

inspect a smaller area as well as possible, then trim away the part that has been inspected and can safely

be removed. Walk each new area again and repeat the inspection before cutting more away. Repeat as often

as necessary until the area is cleared. It can be damaging and/or dangerous to work the cutter in an area

that had not been visually inspected.

Place DANGER signs at least 300 feet beyond the perimeter of the area to be worked, not just 300 feet from

where the machine started operating! It is convenient in many cases to work in 300 foot sections. Move the

first Danger sign to the beginning of the freshly cleared area, place it, then take the first cutting area flag up

to the end of the freshly cleared area 300 feet away. Walk and inspect the next 300 feet and place the

second cutting area flag. Pick up the second DANGER sign, and take it a further 300 feet along the road or

trail. Note that in many cases the DANGER area will extend in front of and behind the machine as well as

along each side. Post signs accordingly.

Use extreme care and Safety Awareness when using the boom mower

head to mulch loose brush or wood that has fallen on the ground from

overhead trimming. DO NOT mulch this debris if bystanders, vehicles,

livestock or buildings are within 300 feet of the mower. This cut debris can

be thrown at great velocities and could result in serious injury or even

death. ^(SBM-17)

WARNING!

DANGER!

Extreme care should be taken when operating near loose objects

such as gravel, rocks, wire, and other debris. Inspect the area before

mowing. Foreign objects should be removed from the site to prevent

machine damage and/or bodily injury or even death. Any objects

that cannot be removed must be clearly marked and carefully avoided

by the operator. Stop mowing immediately if blades strike a foreign

object. Repair all damage and make certain the blade carrier is

balanced before resuming mowing. ^(SGM-5)

DANGER!

Many varied objects, such as wire, cable, rope, or chains, can become entangled in the operating

parts of the Mower head. These items could then swing outside the housing at greater velocities

than the blades. Such a situation is extremely hazardous and could result in serious injury or

even death. Inspect the cutting area for such objects before mowing. Remove any like object

from the site. Never allow the cutting blades to contact such items. (SGM-6)

DANGER!

Always keep a careful lookout and use extreme care when working

around overhead obstructions. Never allow the Mower head or boom

Mower Head is running close to and parallel to the ground without exposed Blades;

Passersby are outside the existing thrown-object zone;

All areas have been thoroughly inspected and all foreign material such as rocks, cans,

glass, and general debris has been removed.

NOTE: Where there are grass and weeds high enough to hide debris that could be struck by the

blades, the area should be: inspected and large debris removed, mowed at an intermediate

height, inspected closely with any remaining debris being removed, and mowed again at desired

final height. (SBM-1)

9.2 Operating Speed and Ground Speed

Ground speed for mowing will depend upon the height, type, and density of vegetation to be cut. Do Not exceed

2 MPH while operating. Operate the mower at its full rated speed to maintain blade speed for a clean cut. The

engine should be operated at 1800-1950 RPM for front mounted pumps. Refer to the tractor operator’s manual or

the tractor instrument panel for the engine speed and gear to provide the required operating and desired ground

speed. Make sure that the mower is operating at its full rated speed before entering the vegetation to be cut.

Always start and stop cutting blades with engine near idle.

Ground speed is achieved by transmission gear selection and not by the engine operating speed. The operator

may be required to experiment with several gear range combinations to determine the best gear and range which

provides the most ideal performance from the implement and most efficient tractor operation. As the severity of

cutting conditions increase, the ground speed should be decreased by selecting a lower gear to maintain the

proper operating PTO speed.

WARNING!

Mow at the speed that you can safely operate and control the tractor and

mower. Safemowingspeeddependsonterrainconditionandgrasstype,

density, and height of cut. Normal ground speed range is from 1/4 to 2

mph. Use slow mowing speeds when operating near steep slopes,

OPERATION

Hedge Trimming

Consider how the job should be tackled before commencing work, as no two hedges have the same height,

width, thickness or density of growth. Hedges which have previously been cut by machine tend to have

denser growth, and although they can be cut to any desired shape, it is advisable to trim the same shape and

height as previous years.

The flails cause the growth to "tiller' and thicken up the hedge. Therefore it is advisable to cut the hedge side

at a slight angle rather than straight, otherwise the hedge may eventually die at the bottom due to lack of

light.

Below are a few hints on how to tackle a hedge.

A. First trim the top down to previous years's trim in one cut, but do not cut into it, as the old growth will be

very thick and strong and cause premature wear to the flail cutting edges.

B. Next trim the sides to the previous trim but not into it.

NOTE: Do not angle the rotor unit so that any debris is thrown through the hedge when trimming the far side

of the hedge. Always ensure cut material is directed away from you or on to the ground.

C. Finally, lower the roller and trim along the bottom of the hedge to clear debris and undergrowth.

OPERATION

Motor Position

All rotor units are supplied with the motor positioned on the left hand side of the cowl. It can be placed on the

other side of the cowl if desired, to suit particular operating conditions. To change the motor to the opposite

side follow the instructions below.

A. Position the cowl horizontally securely supported on stands or blocks, so that either end may be worked

on.

B. Remove the hoses from the motor, plugging the ends and ports to prevent entry of dirt.

C. Remove the motor guard and stay complete.

D. Remove the four nuts from the rotor shaft drive flange.

E. Remove the motor, drive plate, mounting plate, and rubber bushings as one unit by removing the three

attachment bolts, through the rubber bushings separating the rotor shaft from the drive flange, taking care not

to damage the joint faces.

F. Remove the non-drive end bearing guard, loosen the bearing locking set screws and remove the clamping

setscrew in the end of the shaft.

G. Remove the rotor shaft from the cowl. While it is out of the cowl remove all the flails and shackles and

replace with flails facing the opposite direction, but at the same location.

I. Remove the bearing adaptor plate from the left hand side of the cowl and replace in the right hand side of

the cowl.

J. Reassembly is the opposite of the above procedure but with the positions of the items reversed: left hand

side for right hand side and vice versa.

NOTE: Extreme care must be taken to ensure that the mating faces of the drive flange are clean, flat and

undamaged when it is reassembled . If any burrs are found on either face they should be carefully removed

with a fine file. Tighten the 4 flange nuts eventually to a torque of 60Nm (44 ft lbs). Failure to observe this

procedure could result in rotor shaft vibration and/or premature motor failure.

OPERATION

Before transporting the tractor on a public roadway or

boarding a trailer for transport, the tractor brake pedals

should be locked together. Locking the pedals ensures

that both wheels brake simultaneously while stopping,

especially when making an emergency stop.

Use extreme caution and avoid hard application of the

tractor brakes. Maximum transport speed should not

exceed 20 MPH.

11.1 Transporting on Public Roadways

DANGER! Never allow children or other persons to ride on the Tractor or Implement.

Falling off can result in serious injury or death.

(SG-10)

WARNING! Make certain that the “Slow Moving Vehicle” (SMV) sign is installed in

such a way as to be clearly visible and legible. When transporting the

EquipmentusetheTractorflashingwarninglightsandfollowalllocaltraffic

regulations.(SG-6)

Extreme caution should be used when transporting the tractor and mower on public roadways. The tractor must

be equipped with all required safety warning features including a SMV emblem and flashing warning lights to alert

drivers of the tractor’s presence. Remember that roadways are primarily designed for automotive drivers and most

drivers will not be looking out for you, therefore, you must look out for them. Check your side view mirrors

frequently and remember that vehicles will approach quickly because of the tractor’s slower speed. Be extremely

cautious when the piece of equipment that you are towing, is wider than the tractor tire width and/or extends

beyond your lane of the road.

The SMV (Slow-Moving Vehicle) emblem is universal

symbol used to alert drivers of the presence of

equipment traveling on roadways at a slow speed. SMV

signs are a triangular bright orange with reflective red

trim for both easy day and night visibility. Make sure

the SMV sign is clean and visible from the rear of the

unit before transporting the tractor and mower on a public

roadway. Replace the SMV emblem if faded, damaged,

or no longer reflective.

OPERATION

Make sure that all tractor flashing warning lights, headlights, and brake/taillights are functioning properly before

proceeding onto public roads. While newer model tractors have lighting to provide warning signals and operating

lighting, most older models where only equipped with operating lights. Consult an authorized tractor dealer for

lighting kits and modifications available to upgrade the lighting on older tractor models.

When operating on public roads, have consideration for other road users. Pull to the side of the road occasionally

to allow all following traffic to pass. Do not exceed the legal speed limit set in your country for agricultural tractors.

Always stay alert when transporting the tractor and mower on public roads. Especially in busy cities, the boom

extends to right farther then the tractors width, so be careful there are no bystanders, poles,large obstructions or

any vehicles that may be in path of the mower head on boom. Use caution and reduce speed if other vehicles or

pedestrians are in the area.

Ensure that both brake pedals are locked together when

operating on public roads.

11.2 Hauling the Tractor and Mower

Before transporting a loaded tractor and mower,

measure the height and width dimensions and gross

weight of the complete loaded unit. Ensure that the

load will be in compliance with the legal limits set for

the areas that will be traveled through.

OPERATION

Use adequately sized and rated trailers and equipment

to transport the tractor and mower. Consult an

authorized dealer to determine the proper equipment

required. Using adequately sized chains, heavy duty

straps, cables and/or binders. Securely tie down both

the front and rear of the tractor utilizing the proper tie

down locations as specified by the tractor manufacturer.

Arrange the chains so that when tightened, the chains

are pulling downward and against themselves. Carefully

tighten the securing chains or other fasteners used as

much as possible using boomers or binders to apply

maximum tension. Use extreme care when attaching

and removing the securing devices as the extreme

tension involved when released has the potential to inflict

serious injury.

While hauling the tractor and mower, make occasional

stops to check that the tractor and mower have not

moved or shifted and that the securing chains have

maintained tension. If during transport a hard braking,

sharp turning, or swerving action was performed, stop

at the next safe location to inspect the security of the

load.

C. Ensure check chains are securely attached and in good condition.

D. Check that PTO guard is in good condition and replace if not.

E. Check universal joint bearing journals for roughness or slackness. Replace if necessary.

HOSES AND ROTOR DRIVE CIRCUIT

It is false economy to try and make a damage hose last a bit longer, because a failure can spill several

gallons of oil on the road endangering traffic and costing money. To reduce the risk of this happening and

ensure a long life from the hoses follow instructions given below:

A. Check weekly that all hoses and their connections (with particular attention to the rotor drive circuit)

are in good condition and that there are no leaks or damage.

B. Replace any hose that is leaking or damaged.

C. Ensure that hoses have not chafed against sharp edges. If they have, inspect damage and replace if

necessary.

D. Re-route any hose that has been chafing.

E. Ensure that when fitting hoses that they are fitted without kinks or sharp bends.

F. Pay particular attention to the suction hose from tank to pump.

G. If in doubt about the condition of a hose REPLACE IT.

HYDRAULIC OILS

Only use Universal Hydraulic Oil part number 02960575.

PUMP

A 'noisy' pump (whistling or screaming) means that there is air in the rotor drive circuit.

A. STOP THE MACHINE AT ONCE.

B. Locate air entry.

C. Fix and test carefully.

MAINTENANCE

ROTOR UNIT

Vibration of the rotor shaft can cause premature failure of the rotor shaft bearing, as well as hydraulic and

structural failures. It is important not to operate the machine with the head vibrating. As soon as any

vibration is felt stop operating the machine and make the checks listed below:

A. Stop the tractor and disengage the PTO drive.

B. Check for missing flails and always replace missing flails in pairs, on opposite sides of the rotor in

order to maintain the balance of the rotor shaft.. Replace one flail, hanger, bolts and other fittings - rotate

shaft 180^Oand replace the same for each flail.

NOTE: The flails and the rotor shaft are dynamicaly balanced, the flails must be replaced in pairs. If this

is not done the rotor shaft may become out of balance and cause excessive vibration.

C. Check that flail attachments are tight.

If any flails were missing or loose and have been replaced or tightened and the vibration continues check

the following.

D. Stop tractor engine and disengage PTO drive.

E. Check the Rotor Shaft bearings to see if they are damaged or loose.

F. Replace bearings if necessary.

If vibration persists, it is an indication that the rotorshaft is probably bent and must be replaced.

Hydraulic Cylinders

It is advisable to check all cylinder caps for tightness occasionally and if found to be loose, tighten them

immediately.

STORAGE

Before removing the machine from the tractor, a thorough check of the machine should be made as

follows:

A. Thoroughly clean all moving parts, particularly the rotor unit.

B. Check that all flails are in place, and that they are in good condition.

C. Check all hoses for damage, such as cracks, evidence of chafing and leaks.

D. Smear all unpainted metal parts with grease and lubricate all grease fittings.

E. Make a note of item that needs replacing so that parts can be ordered.

PARKING AND REMOVAL

In the parked position the machine is supported by four stands on the mainframe (see FIGURE 5-2) and

also the rotor unit. To put the machine into this position the following procedure is necessary:
