INTRODUCTION  
The Gravely Convertible 7.6 Tractor is available in two models - the  
Custom and the Super. The Super has the added feature of electric starter  
and governor.  
The Convertible 7.6 Tractor is powered by a Gravely engine producing 7.6  
horsepower. All gear drive allows power to be transmitted directly from  
the engine to the power attachment by steel shafts and gears.  
The Convertible 7.6 offers year-around, all-season versatility with many  
different attachments available. Out-front mounting of most attachments  
gives you maximum visibility and safety.  
This tractor will give you highly satisfactory service if maintained and  
operated as outlined in this manual.  
All references to Left Hand and Right Hand; front and rear are given from  
the operators position, as you stand behind the tractor.  
For detailed service information, a service manual is available through your  
dealer or through the home office.  
It is important that you know the Serial Number of your tractor. The Serial  
Number is located on the Left Hand side of the advance casting. See  
Figure 1. The serial number of your tractor is

OPERATION  
STARTING  
Throttle - Depress the throttle to accelerate engine, raise  
to decelerate engine.  
Whether you have a manual starter or an electric starter,  
before starting check to see if:  
Choke - Pull to choke; push forward fully for normal  
operation.  
Operating levers are in neutral .  
Attachment clutch control is in the disengaged  
position .  
Valve on fuel tank is open and fuel in tank  
Oil level is on full mark .  
Throttle is open approximately half-way .  
An attachment or attachment boss cover is secured  
to the front of the tractor.  
Operating Levers - The operating levers, one for high an  
ow speeds and one for forward and reverse are located  
on the right tractor handle.  
Range Control - On tractors with the optional eight spee  
transmission, the range selector lever is on the right by  
the fuel tank. Push forward fully for low range; pull  
rearward fully for high range.  
Attachment Clutch Control - The attachment clutch  
control is the attachment clutch lever that enables you  
to engage or disengage the power attachment from  
your position at the tractor handles. Pull to engage the  
attachment; push to disengage.  
Ignition Stop Button - To stop engine, depress the  
ignition stop button. Keep depressed until the engine  
stops completely.  
Normal Starting - On tractors with the manual starter,  
attach the strap to the pulley (place the hole in the strap  
over the pin in the pulley groove) and wind the strap onto  
the pulley in the direction of the arrow on pulley. Pull the  
strap hard and fast. Choke as required. With the electric  
starter, simply press the starter button with your toe.  
Choke as required.  
NOTE: In proper working order, the engine should start  
with one or two attempts (a few more may be necessary  
in cold weather). If it doesn't, check the Trouble Shooting  
section to find and correct the trouble. Do not tamper with  
the carburetor - this will serve only to complicate things,  
for even with the carburetor out of adjustment, the engine  
should start.  
Cold Weather Starting - Cold weather starting troubles  
usually can be avoided if you:  
Make sure the proper weight oil is used. Oils heavier  
than those recommended will stiffen at low  
temperature thus making starting more difficult .  
Use fresh high quality regular grade gasoline .  
Store the tractor in a heated building if possible.

OPERATING THE TRACTOR  
Figure 3  
Figure 4  
When starting the tractor, have high-low and  
forward-reverse control levers in neutral and the  
attachment clutch control pushed forward fully in the  
disengaged position.  
If the tractor is the eight speed transmission model the  
Range Selection Lever should be in the position for the  
range in which the tractor will be operated initially.  
Engaging wheels - To put tractor in motion, first move  
the high-low control lever to either the high or low  
position (figure 3). Then move the forward-reverse  
control lever into forward or reverse. Depress the  
throttle to the desired speed.  
NOTE: WITH ONLY THE HIGH-LOW CONTROL LEVER  
IN HIGH OR LOW, THE TRACTOR WILL NOT MOVE.  
Engaging Power Attachment - Before attempting to put  
a power attachment in gear, be sure that the tractor is  
stopped, with high-low and forward-reverse control in  
neutral and the engine running at idle speed.  
After the attachment is engaged, increase the engine  
speed to about half-throttle. Move the high-low control  
lever to high or low.  
Braking - The forward-reverse control lever is used as a  
brake when you must stop. Move the lever out of  
forward, pass through neutral, and apply pressure at  
reverse position -enough pressure to stop the forward  
motion of the tractor.  
EIGHT-SPEED TRANSMISSION - The eight speed  
transmission models feature a two-speed axle giving the  
tractor four speeds forward and four speeds in reverse.  
Shifting the axle between high and low ranges controls  
only the tractor's ground speed. Shifting the high-low  
control lever between high and low provides a further  
control over ground speed as well as attachment speed.  
To change axle ranges: Stop the tractor. Keep the  
high-low control lever in high or low, but move the  
forward-reverse control to neutral. Move the range  
selection lever to high or low range. Move the  
forward-reverse control lever back and forth slightly if  
necessary to allow the gears to mesh.  
CAUTION: THIS SHIFT SHOULD ONLY BE MADE ON  
LEVEL GROUND.  
Individual jobs will dictate the combination of axle range  
and gear to be used. In general, low axle range should  
be used for plowing, cultivating, snow blowing, heavy  
mowing, and other jobs where a slower ground speed is  
needed to give the attachment longer to do its job. High  
axle range generally is satisfactory for mowing and other  
lawn jobs.  
Other Points - Don't slip the clutch. If you find the ground  
speed of the tractor too fast for the job, shift to a lower  
gear. If you can't shift any lower, take a smaller cut - one  
on which the attachment can do the job with the tractor  
fully in gear. Repeated clutch slipping causes undue  
wear and should be avoided.  
STANDARD TRANSMISSION - The standard  
transmission models have four speeds - high and low  
in forward and high and low in reverse. These speeds  
control both ground speed and attachment speed, with  
low gear having about 75% of the speed obtainable in  
high gear.  
STOPPING  
To shut off the engine, depress ignition stop button (figure  
2) after disengaging attachment and moving both  
operating levers to neutral.

MAINTENANCE  
heavy loads, change the oil filter every 40 hours.  
LUBRICATION  
The oil filter must be installed by hand. Install the filter  
following the instructions printed on the filter.  
Oil Pressure - Check the oil pressure gauge when  
starting. The level should raise quickly after starting,  
and at full throttle be about 2/3 of the way over in the  
normal range. If the oil pressure is not correct, stop the  
engine and check oil level. If the oil level is not low,  
check your service manual or call your dealer.  
Battery (Electric Start models only) - daily check the  
electrolyte level o the battery. Maintain at proper level  
by adding only distilled water.  
Filling the chassis to its 5 pint (2.36L.) capacity with motor  
oil lubricates both the engine and transmission. Do not  
use transmission oil or grease. The following is  
recommended:  
Summer - SAE 30 or SAE 10W-30. API Classification -  
SC or SD  
Winter - (32 degrees F or below) SAE 10W or SAE  
10W-30 API Classification - SC or SD  
Oil Level - Regularly check the oil level with the Dipstick  
(figure 5) before starting. Be sure the tractor is level.  
Add oil - Add oil by removing the Oil Filler Cap (Figure 5 .  
Stop when the oil reaches the FULL mark on the  
dipstick. (Allow time for the oil to drain down prior to  
checking. This prevents overfilling.)  
AIR INTAKE SYSTEM  
The importance of maintaining an air cleaner in proper  
condition cannot be over-emphasized! Dirt induced  
through improperly installed, improperly serviced  
elements, wears out more engines than does long  
hours 'of operation. Furthermore, operating with a  
clogged element causes a richer fuel mixture which can  
lead to formation of harmful sludge deposits. Always  
cover carburetor or air horn when air cleaner is  
removed for servicing.  
Oil Filler Cap - Periodically check the breather-type oil  
filler cap. Wash it in solvent at least every oil change.  
Oil Changes - Change the oil after the initial eight hours  
of operation. Then change the oil every 40 hours under  
normal conditions, oftener under dusty conditions  
and/or periods of extended operation under heavy  
load.  
Drain oil by removing the oil drain plug, the bottom bolt on  
the Left Hand axle housing.  
Be sure oil drain washer is in place when replacing the  
bolt.  
Dry type air cleaner elements should be serviced only  
when required. Need for air cleaner service is evident  
by a loss of power for no apparent reason.  
To clean, remove element and tap lightly on a flat surface  
to remove loose surface dirt. Replace element if dirt  
does not drop off easily or if the element is  
Oil Filter - Under normal conditions, change the oil filter  
every 80 hours, however, under extremely dusty  
conditions and/or extended operation under

Ignition Troubles - Check to see if:  
….Hood itching the plug. Raise the hood and attempt to  
start the engine .  
….Spark plug is fouled or wet. Remove the plug and  
clean, dry, or replace it. Correct gap to .025 inch (.635  
mm).  
….Engine is getting a spark from the magneto. Remove  
the magneto from the spark plug and crank the  
engine by hand, holding the cable end so that the  
spark can jump to the cylinder head. If there is no  
spark when the magneto is heard to click, or a weak  
spark (less than 3/16 inch or (4.76mm). Check the  
connections. If these are all right, the magneto is  
defective .  
….Ignition stop button is shorted out. To test, remove the  
ground wire from the magneto stop button and  
attempt to start the engine. See service manual or call  
your dealer. (See 5, figure 7.)  
Carburetor and Air Cleaner Trouble - A flooded  
carburetor or a clogged air cleaner may keep the  
engine from starting.  
If gas is dripping from the carburetor, it is flooded. Wait  
10 to 15 minutes before further attempting to start the  
engine.  
Check air cleaner element; if dirty, clean or replace (See  
Air Intake System)  
Figure 6  
damaged in any way. Also, replace element if there is  
any evidence of dirt on the inside surface of the  
element.  
DO NOT wash dry elements in any liquid or attempt to  
blow dirt off with air hose as this will puncture the filter  
element.  
Handle new element carefully - do not use if the gasket  
surfaces are bent, twisted, or damaged in any way.  
Use only genuine Gravely elements. Use of other  
elements will void warranty. Not only must the proper  
element be used but it must be properly installed to  
prevent unfiltered air from entering the engine.  
Install the air cleaner assembly in this sequence on the  
air cleaner mounting bracket:  
1. Rubber gasket  
2. Air cleaner mounting base  
3. Element  
4. Air cleaner cover  
5. Rubber sealing washer  
6. Flatwasher  
7. Wing Nut  
Be sure the element gasket surfaces fit tightly on the base  
and cover. The wing nut should be finger tight.  
Fuel - Use a good grade of regular gas. Premium grade  
should not be used. Fuel tank capacity is  
approximately 1 3/4 gallons (6.63 L.).  
It is good practice to periodically clean the tractor. Dirt  
accumulation on tractor allows heat buildup.  
Figure 7  
Adjustments  
Following are common adjustments which most users can  
readily perform:  
Spark Plug - The spark plug should have its gap set at .  
inch (.635 mm.).  
Troubleshooting  
Clutch Rods - To adjust clutches, tighten the locknuts, 1  
and 2 in Figure 7, until the clutch rod springs are  
compressed fully as each lever goes over center in the  
fully engaged position, either high or low gear or  
forward or reverse.  
Fuel Troubles - Check to see if:  
….Fuel tank contains fuel  
….Vent hole in fuel tank cap is open  
….Fuel shut off valve is open. (Turn counterclockwise to  
open)  
Range Selection Linkage -The toggle spring (locate y  
the range ever occasionally may require adjustment by  
tightening the hex nuts on the toggle rod until the spring  
is compressed to 15/16 inch (23.81 mm). Figure 3 and  
4. To adjust springs, (3 and 4 in Figure 7), have the  
range selection lever engaged fully in high or low  
range, move the hex nuts (1 and 2 in Figure 7) on the  
spring rod until each spring is compressed 2 1/2 inches  
(63.5 mm).  
….Fuel line is clear. Close shutoff valve. Remove fuel line  
from carburetor, and reopen valve. If fuel flows, the  
line is clear; if not, check the fuel hose and fittings,  
and strainer in fuel tank .  
….Carburetor is getting fuel. With the fuel line intact, close  
the shut-off valve. Drain any fuel remaining in the  
carburetor by removing the plug from the bottom of  
the carburetor. Open the shutoff valve. If fuel does  
not flow out of the carburetor there is a restriction in  
the carburetor. See service manual or call your  
dealer.  
Carburetor - If absolutely necessary to adjust the  
carburetor, follow these instructions:

Figure 8  
1. Screw the jet adjustment valve (a brass T-valve) in  
until it is snug. Do not force or screw it tightly.  
2. Back off the jet adjustment valve 1 1/2 turns.  
3. Start the engine and open the throttle halfway. After  
the engine warms up, begin screwing the jet  
adjustment valve in slowly. As soon as the engine  
slows down, stop and back the valve off until engine  
picks up speed.  
4. Screw the idle air jet adjustment valve (a slotted  
head screw with a spring around it) all the way in;  
then back off 1 turn. Start the engine and allow it to  
idle. Screw the idle air jet adjustment valve in until  
the engine begins to run rough. Then back the valve  
off the engine runs smooth.  
Figure 9  
Timing - The magneto should be set to fire approximately 20  
degrees before top dead center. To adjust:  
1. Loosen magneto coupling nut (1, Figure 9) until the  
coupling slips on the camshaft. It may be necessary to  
tap the coupling gently.  
2. Remove the cylinder head.  
3. Bring the piston to top dead center on the compression  
stroke (both valves closed).  
4. Turn the starter pulley counterclockwise until the piston  
goes down the cylinder approximately one inch. Then  
bring the piston back up the cylinder to 3/8 inch  
(9.525mm) from top of cylinder. This procedure takes up  
any backlash in the gears.  
Valves - Adjust the valves only when the engine is cold.  
Remove the valve cover cap, adjust tappet to .015  
(.397mm) inch.  
5. Align the timing marks (straight marks) on the magneto.  
6. Be sure that there is at least .015 inch (.397mm.) end  
play in the magneto coupling so it will not cramp the  
impulse. Use feeler gauge between the fiber block (2,  
Figure 9) before tightening nut. Tighten nut.  
7. Check your settings by backing the piston not more than  
two inches down the cylinder barrel (to avoid picking up  
the magneto impulse) and bring the piston up to 3/8 inch  
from top of cylinder, magneto marks should align.  
8. When timing is correct, install cylinder head and  
magneto cover.  
Fan Belt - Fan belt tension is adjusted by moving the fan  
belt pulley (the pulley at the fan) upwards, to increase  
tension. To adjust; loosen the large thin nut between  
the fan belt pulley and fan housing. Tighten after  
proper tension is reached.

I. Do not let anyone operate the machine until he has had  
proper instructions.  
2. Be sure the work area is clear of objects which might  
be picked up and thrown.  
3. Do not direct the discharge of material toward by-  
standers.  
4. Keep all shields in place.  
5. Disengage power to attachment and stop motor before  
making adjustments.  
6. Do not wear loose fitting clothing that might get caught  
in moving parts and keep your hands and feet away  
from moving parts.  
7. Never operate the Mower unless the Front Fender or  
optional Chain Guard is on the front of the Mower, and  
the Rear Fender is on the rear.  
8. WHEN USING THE 30-INCH ROTARY MOWER,  
NEVER SHIFT THE INSIDE OPERATING LEVER  
DIRECTLY FROM HIGH TO LOW. ALWAYS PAUSE  
MOMENTARILY IN NEUTRAL, GIVING THE BLADE A  
CHANCE TO SLOW DOWN NATURALLY, THUS  
AVOIDING THE SEVERE BRAKING ACTION FROM A  
SUDDEN SHIFT INTO LOW GEAR.  
Figure 10  
ADJUSTMENTS  
Swivel Action Adjustment  
Swivel action of the Drive Assembly is regulated by the  
Swivel Adjustment Bolt and Nut, (Figure 11 ).  
Loosening the Adjustment Nut frees swivel action;  
tightening it restrains swivel action.  
Figure 11  
LUBRICATION  
Use SAE 140 or 90W EP gear lubricant in the Gear  
Housing. Use General Purpose Grease occasionally in  
the Gear Fitting of the Swivel Casting.  
Check the Gear Housing oil level every eight hours of  
operation by removing the Oil Level Plug (Figure 11). If  
oil runs out, the oil level is all right, if not, oil must be  
added.  
To add oil, remove the Oil filler Plug, (Figure 11 ), and  
pour through the Oil Filler Hole until oil begins to run out  
the Oil Level Hole. Replace both plugs before operating.  
Figure 12  
Cutting Height Adjustment  
Cutting height is adjusted by the Collars on the Rotor  
Shaft. The closer the Blade is to the Gear Housing, the  
higher the cut, and vice versa.  
ATTACHING  
Blade Sharpening  
The 30" Rotary Mower cuts a maximum swath of 30  
inches or 76.2 centimeters and is attached to the tractor  
using two Nuts and two Bolts. See Figure 10.  
Use a grindstone to sharpen the Blade. Try to follow the  
same bevel as the originally-sharpened cutting edge,  
although the precise degree of bevel is not critical.

Fender Adjustment  
When mowing short weeds and lawns, the Front Fender  
(the small fender) should be on the front of the Mower  
Hood, and the Rear Fender (The Larger Fender) on  
the rear.  
However, when mowing high, heavy brush, or thick tough  
grass of considerable height, better mowing results will  
be obtained by removing the Front Fender, and  
replacing it with the optional chain Guard.  
30" ROTARY MOWER ATTACHMENTS  
Chain Guard  
2. Attach the Leaf Mulcher to the rear of the Mower  
Hood, in the position normally occupied by the Rear  
Fender.  
To operate the Leaf Mulcher, proceed the same as you  
would in mowing. Normal walking speed is usually  
adequate to do a good job, although when leaves are  
wet or packed down, you may have to go over the area  
twice.  
Circular Saw  
Figure 13  
When the Front Fender is removed, it must always be  
replaced with the optional Chain Guard. It is attached to the  
Mower by Bolts in place of the Front Fender. The Chains reduce  
the velocity of materials that may be thrown out.  
Leaf Mulcher  
Figure 15  
Attach the 18-inch (45.72cm) circular saw to the drive  
assembly as follows:  
1. Remove the mower assembly from the drive  
assembly.  
2. Place all collars but two on the rotor shaft. Place the  
circular saw on the shaft and then the remaining  
collars and then install the nut and tighten securely.  
NOTE: Cutting edges of the saw teeth must face in the  
direction of the shaft rotation.  
4. Install the saw guard of the gear housing.  
Operating Hints  
Feed the Circular Saw by exerting slight pressure  
on the Tractor Handles. Do not force the Saw .  
...The Circular Saw is most effective for clearing land of  
saplings, sprouts, and other small growth. We do not  
recommend the Circular Saw for felling large trees .  
....Be careful not to run the Saw into the ground or against  
rocks.  
Figure 14  
Storage  
Attach the Leaf Mulcher to the 30-inch Rotary Mower as  
follows:  
When the Circular Saw is to be stored for several days  
or longer, we recommend you coat it with general  
purpose grease.  
1. Remove both the Front and Rear Fenders. Bolt the  
Rear Fender to the front of the Mower Deck.

17).  
Remove Belts from around Rotor Pulley and Idler Pulleys.  
Remove the two Nuts and three Bolts holding the Drive  
Mounting Plate to the Deck. Remove the Drive and  
Belts.  
Replace Belts by reversing the above procedure.  
Put new Belts on Drive Pulley before re-attaching Drive  
Plate to Mower.  
Cutting Height Adjustment  
The cutting height o e Mower is adjusted by the Collars on  
the Rotor Shaft. The closer the Blades are to the under  
side of the Deck, the higher the cut, and vice versa.  
Vary the combination of the Collars as you desire.  
Caster Wheel Adjustment  
Figure 17  
LUBRICATION  
Caster Wheels keep the Mower parallel to the ground. If  
the Mower cuts closer on one side than it does on the  
other, or if the Skids mark the ground, the Caster  
Wheels should be adjusted. Adjustment is  
accomplished by removing "Hairpin" Cotters from the  
top of the fork, and rearranging the Spacing Washers as  
required.  
To replace Wheels, remove Elastic Stop Nut and remove  
the Axle Bolt, replace with new Wheel by reversing the  
procedure.  
Check the Gear Housing oil level every eight hours of  
operation by removing the Oil Level Plug shown at A in  
Figure 17. If oil runs out, the oil level is all right, if not,  
oil must be added until the proper oil level is obtained.  
To add oil, remove the Oil Filter Plug shown at B in Figure  
17, and pour through the hole until oil begins to run out  
the oil level hole. Replace both Plugs before operating  
the Mower. Use SAE 140 or 90W EP lubricant. Use a  
good grade of general purpose grease occasionally in  
the grease fitting of the Swivel Casting.  
Blade spindles should be lubricated every 8 hours of  
service with general purpose grease. Apply lubricant  
through the grease fitting until lubricant starts to come  
out the vent hole on the opposite side of the spindle.  
No lubrication is required for the two Belt - Tightening  
Idler Pulleys.  
Blade Sharpening  
Use a grindstone to sharpen the blade. Try to follow the  
same bevel as the originally sharpened cutting edge,  
although the precise degree of the bevel is not critical.  
Removing the Blades  
Use a standard 3/8 inch socket drive in the square hole in  
the bottom of the rotor shaft to hold the shaft while  
removing the blade nut.  
ATTACHING  
The 40" Rotary mower cuts a maximum swath of 40  
inches or 1.006 meters. It attaches to the tractor using  
2 bolts and two nuts as shown in figure 16.

Never handle the attachment by any cutting surface.  
Keep hands away from Knife Sections. Grasp the  
Mower by its Drive Column and other non-cutting  
surfaces to carry it.  
Try to keep clear of rocks and debris, as these will  
damage the cutting surfaces.  
SICKLE MOWER  
ADJUSTMENTS  
To insure satisfactory performance, perform the following  
adjustments as required:  
Bolts  
Although the Sickle Mower is built and balanced carefully  
it is still subject to vibration. Periodically tighten all Nuts  
and Bolts, doing this at more frequent intervals when  
doing heavy cutting.  
Clips  
proper adjustment, the Clips should allow the Knife to  
slide back and forth easily (with the pressure of a finger  
and thumb). The Clips should hold the Knife in firm  
contact with the Shear Plates, (7 in Figure 19), but  
should not cause binding. To adjust, knock the Clips  
down gradually with taps from a light hammer.  
Swivel Action  
To increase swivel action allowing the Mower to follow the  
contour of the ground, loosen the Bolts, (6 in Figure  
19).  
Figure 18  
When these Bolts are tightened firmly, the Mower is held  
in rigid position. The Bolts should be tight enough to  
the Guide Bar will hold its position until lowered, but  
loose enough for the Guide Bar to follow the contour of  
the ground.  
Guards  
Always keep the Guards, (7 in Figure 19), in alignment.  
Tap with a light hammer until the knife sections lie flat  
on the Shear Plates of the Guards. Keep the Guard  
Bolts tightened securely.  
CARE OF THE KNIFE  
For best performance, keep the Knife Sections sharp. To  
remove the Knife for sharpening, remove the Knife  
Brackets Screws, (5 in Figure 19) and slip the Knife out  
either side. Grind the Knife sections along the same  
bevel as ground originally. When replacing the Knife,  
make sure the Knife Bracket Screws are tightened  
firmly.  
NOTE: It is good practice always to have an extra Knife,  
already sharpened, which you can put on the Mower  
when needed.  
No lubrication is required for the Knife while in operation.  
However, to prevent rust, oil the Knife and Guide Bar  
with a thin coat of light oil after operating. Use a paint  
brush or similar type of applicator. When the Mower is  
to be stored for any period of time, clean it thoroughly  
and apply general purpose grease to all unpainted  
parts.  
Figure 19  
LUBRICATION  
Check the Drive Assembly oil level every 8 hours of  
operation by removing the Oil Level Plug, (8 in Figure  
19). If oil runs out, the oil level is all right; if not, oil must  
be added.  
To add oil, remove the Oil Filter Plug, (2 in Figure 19), and  
pour through the Oil Filler Hole until oil begins to run  
out the Oil Level Hole. Replace both Plugs before  
mowing.  
OPERATING HINTS  
Always mow at a normal walking speed with the Tractor in  
low gear. Excessive speed will exaggerate the Mower  
vibration, causing the Nuts and Bolts to become loose.  
If excessive vibration is encountered, check to see if the  
Wearing tip (on the end of the Actuating Lever) is worn  
or missing, or if the Bracket is worn badly.  
If cut grass or weeds begin collecting on the Mower  
instead of feeding-off properly, check the alignment of  
the Guards and Knife Sections, as well as sharpness of  
the Knife Sections.  
Use SAE 140 in the Drive Assembly.  
To lubricate the Universal Joint, remove the Grease Plug,  
(3 in Figure 19), and fill about half-full with general  
purpose grease.  
ATTACHING  
The Sickle Mower attaches to the convertible 7.6 tractor  
using two Nuts and two Bolts. See Figure 18.  
If this does not correct the improper feed-off, make sure  
one end of the Mower is not dragging up already cut  
material. This is the result of taking too small a "bite".  
Another cause of improper feed-off is a rusty or gummy  
Mower. Always keep it clean.  
SAFETY PRECAUTIONS  
Never attempt to clear the Mower, or make any  
adjustment whatsoever, unless the attachment is out of  
gear and stopped, and the Tractor Engine is stopped.

Cart  
SAFETY PRECAUTIONS  
1. Do not let anyone operate this machine without proper  
instructions.  
2. Do not drive too close to a creek or ditch.  
3. Watch out for traffic when near roadway.  
4. Stay alert for holes and other hidden hazards.  
5. Watch where you are driving. Pay attention.  
6. Beware of steep slopes.  
7. Reduce speed on all side slopes and sharp turns to  
prevent tipping or losing control.  
8. Do not attempt to operate the machine when not in the  
operator's position.  
9. Don't carry passengers.  
OPERATING HINTS  
Filling the Roller: move the Roller until the Filler Plug (a large  
plug on the side of the Roller) is at its highest point. Remove  
the plug to fill the Roller; be sure it is replaced after filling.  
Water generally is used.  
Dumping Cart. The cart is dumped by releasing the Lever  
which holds the Cart to the frame and tilting the Cart to  
the frame and tilting the Cart to the rear.  
Distribution Controls: To determine the proper distribution  
of seed or fertilizer, refer to the self-explanatory

plate attached to the Hopper. Simply set the Port Lever to  
the indicate opening to distribute seed or fertilizer  
properly.  
Care of Hopper Assembly: Many materials used in the  
Seeder-Spreader, especially certain fertilizers, are  
corrosive. Abrasives also are present. This means the  
protective paint soon will wear off the Port Assembly  
and Agitator. To protect these surfaces,  
wash the Seeder-Spreader thoroughly with water after  
using and let it dry, preferably in the sun. If you do not  
intend to use it again within a few days, pour a small  
quantity of oil along the Port Openings and work the  
Port Lever back and forth to distribute the oil.  
A final cutting depth adjustment, is required, is made by sliding  
the Wheel Bracket Clamp, (1 in Figure 24), up or down in the  
slitted Wheel Bracket. The lower the Clamp is set, the lower  
depth of cut.  
TWIN-TOOL GARDENING  
ROTARY PLOW AND ROTARY CULTIVATOR  
Figure 23  
Figure 24  
Plowing Angle Adjustment  
The Rotary Plow is attached to the Tractor by two Nuts and  
two Bolts. One Bolt and one Nut must be used to attach  
the Angle Adjusting Bracket, upper left in Figure 23.  
When plowing for the first time, set the Plow at the  
approximate angle to the ground as shown in Figure 24.  
The Nut which secures the Angle must be loosened to do  
this; be sure it is tightened firmly after the proper angle is  
set.  
LUBRICATION  
Check the Gear Housing oil level every eight hours of  
operation. Gear Housing capacity is 1 1/2 pints. Use  
SAE 140 or 90W EP gear lubricant.  
The bolt through angle adjusting bracket should be  
about 3/4 inch (19.05cm) from the bottom of the slot.  
If there is excessive drag to the left (left, as you stand  
at the handles) move the Plow in the direction of the  
arrow in Figure 24. If there is excessive drag to the right,  
move the Plow opposite the direction of the arrow.  
A few trials may be required before the Plow is  
adjusted properly to soil conditions.  
Add oil by removing the Oil Filter Plug (I in Figure 20). Use  
occasionally General Purpose Grease in the swivel  
casting grease fitting, (2 in Figure 23).  
SAFETY PRECAUTIONS  
1. Do not let anyone operate the unit without proper  
instructions.  
2. Keep all shields and safety devices in place.  
3. Disengage power to any attachment and stop engine  
prior to making adjustments.  
4. Pay attention to what you are doing.  
5. Don't wear loose fitting clothing that might get caught in  
moving parts. Keep hands and feet away from moving  
parts.  
Width of Cut Adjustment  
The width of cut is governed by the position of the  
Wheel Bracket in relation to the Depth Wheel in the  
furrow. The closer the Wheel Bracket is to the Depth  
Wheel in the furrow, the narrower the cut, and vice versa.  
DIRT SHIELD  
The Dirt Shield is attached to the top of the Gear  
Housing by removing the bolts, (4 in Figure 23). inserting  
them through the Shield, and replacing in the Gear  
Housing. You can use the Dirt Shield to direct the throw  
of the dirt, by bending it up or down.  
ADJUSTMENTS  
Depth of Cut Adjustment  
Use the pin or clip, (3 in Figure 23), in the Hex Shaft for  
initial Cutting depth adjustment. The higher on the Shaft  
the Pin is inserted, the greater the depth of cut and vice  
versa. Ordinarily, the Pin is inserted in one of the top  
holes for plowing and in the bottom hole for transporting.

Figure 26  
Figure 25  
OPERATING INSTRUCTIONS  
4. Fit the Hood as shown in Figure 26. Insert the  
Cultivator Drive Shaft into the Gear Housing.  
5. Rotate the Cultivator to the position shown in Figure  
27. In this position the Tines will cut the same  
direction (clockwise) as the forward movement of the  
tractor.  
To plow, first run a furrow down the center of the land to  
be plowed. Then pivot the Tractor at the end of the  
furrow so the Right Depth Wheel is in the furrow just  
made. Continue this way so the dirt is always thrown  
toward the center (see Figure 25).  
If you are plowing a large area, you will be able to "pull"  
the Tractor around corners without pivoting. However,  
in small areas it is necessary to pivot the Tractor each  
time.  
When you are ready to pivot, bear down on the Handles  
until the Tractor is balanced. "Slip" the Clutch gently,  
holding back on the Right Handle, allowing the Engine  
to pivot the Tractor with little effort on your part.  
Plowing is much easier if the Gear Housing is kept level  
with the ground when the Plow is in the furrow and  
plowing. To do this, try to obtain all depth adjustment  
by the holes in the Hex Shaft, and the horizontal  
adjustment by moving the Wheel Bracket laterally.  
If you have the eight-speed Transmission, we recommend  
plowing with the Tractor in low range, which slows  
ground speed to a virtual crawl without affecting  
attachment RPM.  
6. Use the Lock Nuts to fasten the Cultivator Drive  
securely to the Gear Housing.  
7. Install the Dust Shield and Fastener on the top of the  
Hex Shaft.  
8. Use the Adjusting Bracket to lock the Cultivator in  
place with the long axis of the Cultivator parallel to  
the Tractor Axles.  
NOTE: The Gravely Triple-Purpose Wrench, available  
from your Gravely dealer, fits the Cultivator Tine  
Shaft Nut.  
ROTARY CULTIVATOR  
The Rotary Cultivator is attached to the Rotary Plow  
Drive Assembly as follows:  
1. Leave the Plow Angle Adjusting Assembly (upper  
left in Figure 23) attached.  
2. Remove the Hex Shaft (and Plow Blades) from the  
Gear Housing.  
The Depth Wheels, Wheel Bracket and Column  
Assembly (which connects the Wheel Bracket to the  
Gear Housing) may be removed.  
NOTE: After the Column Assembly has been removed,  
Bolts must be inserted into the Gear Housing to prevent  
oil leakage. We recommend short Bolts for this purpose; if  
the original Bolts are tightened, the Gears inside the Gear  
Housing will be fouled. If, however, you use the original  
Bolts, place sufficient Washers on them to prevent Gear  
fouling.  
3. Remove the four Bolts from the bottom of the Gear  
Housing and insert the studs furnished.  
NOTE: When assembling the rotary cultivator to the  
plow drive; be sure the oil plug on the drive housing is up  
when the cultivator is in the operating position.  
Figure 27  
LUBRICATION  
Check the Cultivator Drive Assembly oil level every eight  
hours of operation by removing the Oil Level Plug, (1 in  
Figure 27). If oil runs out of the Oil Level Hole, the oil  
level is all right; if not, oil must be added.  
To add oil, remove the Oil Filler Plug, (2 in Figure 27),  
and pour through the Oil Filler Hole until oil begins to  
run out of the Oil Level Hole. Replace both Plugs when  
proper oil level is reached.  
Use SAE 140 or 90W EP gear lubricant. Be sure the  
Cultivator is level when checking or adding oil.

OPERATING HINTS  
STORAGE  
The Rotary Cultivator is designed for cultivating soil which  
has been broken previously. It is not recommended for  
use as a Plow. Use the Gravely Rotary Plow to prepare  
a seedbed in one operation and the Rotary Cultivator  
for cultivation throughout the season.  
When the Cultivator is detached from the Drive  
Assembly, place the small Spacers over the Studs and  
secure in place with locknuts.  
CULTIVATOR TOOLHOLDER  
Usually it is necessary to detach the bars from the Depth  
Wheels to make these different set-ups.  
Usually the Depth Wheels provide all the adjustments  
required. However, if required, the Shanks can be  
moved up or down in the Shank Holders for additional  
adjustment.  
Five Steel Set-Up is the standard arrangement; 1 1/4  
inch (3.18cm) wide steels are used. (Figure 28).  
Steels are available in 1 1/4 (3.18cm) 1 3/4 (4.45cm) and  
2 1/4 (5.72cm) inch widths; standard length of the  
Steels is eight inches (20.32cm).  
Figure 28  
The Cultivator Toolholder, shown in Figure 28, can be  
used to hold a variety of cultivating tools. The most  
common set-up of cultivating tools in the Toolholder is  
shown.  
In addition, the Cultivator Toolholder is used to hold the  
36-inch Scraper Blade.  
LUBRICATION  
No lubrication is required, except oiling occasionally bolt  
threads for easier operation.  
Figure 29  
ATTACHING  
Six-inch (15.24cm) Hiller Set-Up uses right and left  
Hillers; these can be used for closing rows as well as  
for the killing. Hillers can be used to throw dirt away  
from or around the plants as desired. A furrower,  
available in 10 (25.40cm) or 12-inch (30.48cm) depths,  
can be used with the Hillers to bring from the center of  
the row to the Hillers, which in turn throw dirt around  
the plants. (Figure 29)  
Attaching to Tractor: the Toolholder is attached to the  
front of the tractor the same as power attachments.  
The Attachment Clutch Control should be at the OUT  
position.  
Attaching Tools to Toolholder: the individual cultivating  
tool (1 in Figure 28), is attached to a Shank, (2 in  
Figure 28), which in turn is attached to the Toolholder  
by a Shank Holder (3 in Figure 28).  
The Toolholder is equipped with five Shank Holders.  
These may be moved to different positions on the  
Toolholder, if desired, although this is seldom  
necessary. Additional Shank Holders may be  
purchased from your Gravely dealer.  
To attach a tool to its Shank, simply bolt it in place with  
the Bolts and Nuts provided.  
To attach the Shank to the Shank Holder, loosen the  
Hexagon-Head Cap Screw in the side of the Shank  
Holder, slip the Shank into the Shank Holder from the  
bottom, and lock the Shank in place at the desired  
position by tightening the Cap Screw.  
Changing Tools: after the Shanks have been attached to  
the Tool holder, changing cultivating tools requires only  
the unbolting of the old tool from its Shank and bolting  
the new tool on.  
Parallel Bars: The Parallel Bars, (4 in Figure 28), can be  
adjusted in several ways, depending on the task.  
Figure 30

Furrowers can be used to lay off rows for planting. Also,  
many users find the Furrowers good tools for digging  
potatoes. For smaller furrowers, seven-inch (17.78cm)  
Shovel Steels are available; these can be used to lay  
off small seed crops and for center row cultivation.  
Sweep and Hoe Set-Up uses an improved Sweep in the  
center and a right and left Hoe on the sides. The  
Sweep comes in 8 (20.32cm) 10 (25.40cm) 12  
(30.48cm) and 16 (40.64cm) inch sizes. The Sweep  
clears the center of weeds and trash, while the Hoes  
eliminate the majority of handwork close to the plants.  
(Figure 31)  
Adjustments: The Depth Wheels are used to set the depth  
the cultivating tools penetrate and ground. Facing the  
Depth Wheels, turn the Handwheels clockwise for  
deeper cultivation and counterclockwise for shallower  
cultivation.  
OPERATING HINTS  
Rows should be planted enough apart to accommodate  
the Tractor and Tool Holder. Normal distance between  
rows is 32 (812.8cm) to 36 (914.4cm) inches. Rows  
should be planted farther apart for plants which spread  
widely, unless you intend to shield theTool Holder so  
plants will not be damaged.

LUBRICATION  
3. Keep children and pets a safe distance away.  
4. Do not allow children to operate machine, nor allow  
adults to operate it without proper instructions.  
5. Adjust height of skids clear gravel or crushed rock  
surface.  
All major bearings of the Snowblower that require lubricant  
are permanently lubricated, or are lubricated from the  
Tractor Transmission. However, the operator should  
check the oil level in the Gear Box by removing the  
upper plug,. Oil should never be low, add SAE 140  
lubricant.  
6. Exercise caution to avoid slipping or falling,  
especially when operating in reverse.  
7. Know the controls and how to stop quickly.  
ATTACHING  
ADJUSTMENT  
The Snowblower Drive Housing mounts to the front of the  
Tractor, using two bolts and two nuts. When attaching to  
the Tractor, the Chute Control Crank should be attached  
to the top Sprocket Housing Shaft of the Snowblower  
with the Rubber Connector and two (2) Clamps which  
are provided. See Figure 32.  
The Crank should then be mounted to the Tractor left  
Driving Handle with the Crank Support and Crank  
Support Clamp.  
Discharge Chutes: to position the Discharge Chute, turn  
the Control rank. The Discharge Chute will rotate  
approximately 165 degrees from extreme left, through  
the vertical position, to the extreme right.  
As the Crank is turned, the Defector opening is also  
rotated from the extreme left position through a forward  
position approximately 180 degrees to the extreme  
right position.  
Deflector: to provide accurate placement of the blown  
snow near the Blower on either side or forward throw,  
loosen the Large Wing Nut on the Deflector and adjust  
the Deflector position.  
CAUTION: Be sure Engine is stopped and Attachment  
out of gear and stopped.  
Skids: To raise or lower the Snowblower cutting edge,  
first disengage the power take off and stop the Tractor  
Engine. Then loosen the Skid Mounting Bolts and slide  
the Skids up or down as desired, and retighten the  
Skid Mounting Bolts securely. This adjustment can be  
made more accurately if the cutting edge is placed on  
blocks while the adjustment is made.  
Safe Snow Removal is No Accident  
Improper use of snow removal equipment on the part of the  
operator can result in injury. To reduce this possibility,  
give complete and undivided attention to the job at hand.  
Protect yourself and others by following these safety tips:  
1. Stop Engine before removing obstacles, making  
adjustments (except with the Control Crank), or when  
leaving the operating position.  
Reel Clutch: the Reel Clutch is properly adjusted at the  
factory. If it should become necessary to tighten the  
Friction Clutch in the Reels, turn off the Tractor Engine,  
disengage the Power Take Off, and after all movement  
has stopped, block the rotation of the Fan. Now tighten  
the large Nut on the right end of the Reel Shaft (as  
viewed from the front of the Snowblower). See Figure  
33.  
2. Disengage the Power Take off and wait until the Fan  
stops before adjusting the deflector. Never direct  
discharge at bystanders, or allow anyone in front of  
machine - debris may be hidden in the snow.

are included. These bolt to the inner sides of the  
Frame and may be used in place of the Skids.  
The Caster Bracket Holes are slotted, and three (3) pairs  
of holes are provided in the frame for height  
adjustment.  
OPERATING HINTS  
Keep the Engine at full throttle when using the  
Snowblower. With the Swiftamatic transmission, use  
low axle range.  
ACCESSORIES  
If the Tractor stops suddenly while operating the  
snowblower, check the vent in the Fuel Tank Cap for  
clogging.  
A special Accessory Kit is available which includes:  
Drift Cutters. Two Cutters are provided. These mount  
inside the Reel Housing ends and extend upward to  
slice through snow up to 30-inches (76.2cm) deep. The  
Drift Cutters are flared to assist turning in deep snow.  
No adjustment is necessary.
