SAFETY
• Do not mow in reverse.
• Tires may lose traction on slopes even though the brakes are functioning
properly.
• Shut off blades when you are not mowing.
• Avoid starting, stopping or turning on a slope. If the tires lose traction,
disengage the blades and proceed slowly, straight down the slope.
• • Park machine safely before leaving the operator station for any reason
including emptying the catchers or unplugging the chute.
• Keep all movement on slopes slow and gradual. Do not make sudden
changes in speed or direction, which could cause the machine to roll over.
Protect Children
c
• Use extra care while operating machine with grasscatchers or other
attachments, they can affect stability of the machine. Do not use on steep
slopes.
• Do not mow near drop-offs, ditches, embankments, or bodies of water.
The machine could suddenly roll over if a wheel goes over the edge or the
edge caves in.
• Follow the manufacturer’s recommendations for wheel weights or
counterweights for added stability when operating on slopes or using front
or rear mounted attachments. Remove weights when not required.
• Drive machine very slowly and avoid quick stops when attachment is
removed.
• Transport machine with decks lowered to improve stability.
Keep Riders Off
• Death or serious injury can occur when young children associate having
fun with a lawn mowing machine simply because someone has given
them a ride on a machine.
• Only allow the operator on the machine. Keep riders off.
• Riders on the machine or attachment may be struck by foreign objects or
thrown off the machine causing serious injury.
• Children are attracted to lawn mowing machines and mowing activities.
They don’t understand the dangers of rotating blades or the fact that the
operator is unaware of their presence.
• Riders obstruct the operator’s view resulting in the machine being
operated in an unsafe manner.
• Children who have been given rides in the past may suddenly appear in
the mowing area for another ride and be run over or backed over by the
machine.
Avoid High Pressure Fluids
• Hydraulic hoses and lines can fail due to physical damage, kinks, age,
and exposure. Check hoses and lines regularly. Replace damaged hoses
and lines.
• Tragic accidents with children can occur if the operator is not alert to the
presence of children, especially when a child approaches a machine from
behind. Before and while backing up, stop mower blades and look down
and behind the machine carefully, especially for children.
• Hydraulic fluid connections can loosen due to physical damage and
vibration. Check connections regularly. Tighten loose connections.
• Escaping fluid under pressure can penetrate the skin causing serious
injury. Avoid the hazard by relieving pressure before disconnecting
hydraulic or other lines. Tighten all connections before applying pressure.
• Never carry children on a machine or attachment, even with the blades
off. Do not tow children in a cart or trailer. They can fall off and be
seriously injured or interfere with safe machine operation.
• Search for leaks with a piece of cardboard. Protect hands and body from
high pressure fluids.
• Never use the machine as a recreational vehicle or to entertain children.
• Never allow children or an untrained person operate the machine.
Instruct all operators not to give children a ride on the machine or in an
attachment.
• If an accident occurs, see a doctor immediately. Any fluid injected into
the skin must be surgically removed within a few hours or gangrene may
result. Doctors unfamiliar with this type of injury should reference a
knowledgeable medical source.
• Keep children indoors, out of the mowing area, and in the watchful eye of
a responsible adult, other than the operator, when a mower is being
operated.
Checking Wheel Hardware
• Stay alert to the presence of children. Never assume that children will
remain where you last saw them. Turn the machine off if a child enters the
work area.
• A serious accident could occur causing serious injury if wheel hardware
is not tight.
• Check wheel hardware tightness often during the first 100 hours of
operation.
Avoid Tipping
• Wheel hardware must be tightened to specified torque using the proper
procedure anytime it is loosened.
• Slopes are a major factor related to loss-of-control and tip-over
accidents, which can result in severe injury or death. Operation on all
slopes requires extra caution.
Wear Appropriate Clothing
• Mow across slopes, not up and down.
• Always wear safety goggles, or safety glasses with side shields, and a
hard hat when operating the machine.
• Watch for holes, ruts, bumps, rocks, or other hidden objects. Uneven
terrain could overturn the machine. Tall grass can hide obstacles.
• Wear close fitting clothing and safety equipment appropriate for the job.
• Choose a low ground speed so you will not have to stop or shift while on
a slope.
• While mowing, always wear substantial footwear and long trousers. Do
not operate the equipment when barefoot or wearing open sandals.
• Do not mow or operate machine on wet grass. Tires may lose traction. • •

SAFETY
• Wear a suitable protective device such as earplugs. Loud noise can
cause impairment or loss of hearing.
• Check fuel lines, tank, cap, and fittings frequently for cracks or leaks.
Replace if necessary.
Maintenance and Storage
Tire Safety
Explosive separation of a tire and rim parts can cause serious injury or
death:
• Never operate machine in a closed area where dangerous carbon
monoxide fumes can collect.
• Do not attempt to mount a tire without the proper equipment and
experience to perform the job.
• Disengage drives, lower implement, lock parking brake, stop engine and
remove key or disconnect spark plug (for gas engines). Wait for all
movement to stop before adjusting, cleaning or repairing.
• Always maintain the correct tire pressure. Do not inflate the tires above
the recommended pressure. Never weld or heat a wheel and tire
assembly. The heat can cause an increase in air pressure resulting in a
tire explosion. Welding can structurally weaken or deform the wheel.
• Clean grass and debris from cutting units, drives, mufflers, and engine to
help prevent fires. Clean up oil or fuel spillage.
• Let engine cool before storing and do not store near flame.
• When inflating tires, use a clip-on chuck and extension hose long
enough to allow you to stand to one side and NOT in front of or over the
tire assembly.
• Shut off fuel while storing or transporting. Do not store fuel near flames
or drain indoors.
• Park machine on level ground. Never allow untrained personnel to
service machine. Understand service procedure before doing work.
• Check tires for low pressure, cuts, bubbles, damaged rims or missing lug
bolts and nuts.
• Use jack stands or lock service latches to support components when
required. Securely support any machine elements that must be raised for
service work.
Handling Fuel Safely
To avoid personal injury or property damage, use extreme care in
handling fuel. Fuel is extremely flammable and fuel vapors are
explosive:
• Before servicing machine or attachment, carefully release pressure from
any components with stored energy, such as hydraulic components or
springs.
• Extinguish all cigarettes, cigars, pipes, and other sources of ignition.
• Release hydraulic pressure by lowering attachment or cutting units to the
ground or to a mechanical stop and move hydraulic control levers back
and forth.
• Use only an approved fuel container. Use only non-metal, portable fuel
containers approved by the Underwriter’s Laboratory (U.L.) or the
American Society for Testing & Materials (ASTM). If using a funnel, make
sure it is plastic and has no screen or filter.
• Disconnect battery or remove spark plug (for gas engines) before
making any repairs. Disconnect the negative terminal first and the positive
last. Reconnect positive first and negative last.
• Never remove the fuel tank cap or add fuel with the engine running.
Allow engine to cool before refueling.
• Use care when checking blades. Wrap the blades or wear gloves, and
use caution when servicing them. Only replace blades. Never straighten
or weld them.
• Never add fuel to or drain fuel from the machine indoors. Move machine
outdoors and provide adequate ventilation.
• Clean up spilled fuel immediately. If fuel is spilled on clothing, change
clothing immediately. If fuel is spilled near machine, do not attempt to start
the engine but move the machine away from the area of spillage. Avoid
creating any source of ignition until fuel vapors have dissipated.
• Keep hands, feet, clothing, jewelry and long hair away from moving
parts. If possible, do not make adjustments with the engine running.
• Charge batteries in an open well ventilated area, away from spark and
flames. Unplug charger before connecting or disconnecting from battery. •
Wear protective clothing and use insulated tools.
• Never store the machine or fuel container where there is an open flame,
spark, or pilot light such as on a water heater or other appliance.
• Keep all parts in good working condition and all hardware tightened.
Replace all worn or damaged decals.
c
c
• Check grass catcher components and the discharge guard frequently
and replace with manufacturer’s recommended parts, when necessary.
Grass catcher components are subject to wear, damage, and deterioration
which could expose moving parts or allow objects to be thrown.
• Keep all nuts and bolts tight, especially blade attachment bolts, to be
sure the equipment is in safe working condition.
• Check brake operation frequently. Adjust and service as required.
• On multi-bladed machines, take care as rotating one blade can cause
other blades to rotate.
Prevent Fires
• Remove grass and debris from engine compartment and muffler area,
before and after operating machine, especially after mowing or mulching
in dry conditions.
• Empty the grass catcher completely before storing.
• Always shut off fuel when storing or transporting machine, if the machine
has a fuel shutoff.
• Prevent fire and explosion caused by static electric discharge. Static
electric discharge can ignite fuel vapors in an ungrounded fuel container.
• Do not store machine near an open flame or source of ignition, such as a
water heater or furnace.
• Never fill containers inside a vehicle or on a truck or trailer bed with a

OPERATING
plastic liner. Always place containers on the ground away from your
vehicle before fueling.
• Be careful not to spill fuel on machine. Fuel may damage surface. Wipe
up spilled fuel immediately.
• Remove fuel-powered equipment from the truck or trailer and refuel it on
the ground. If this is not possible, then refuel such equipment with a
portable container, rather than from a fuel dispenser nozzle.
• Prolonged exposure to sunlight will damage the hood surface.
Operator Station Controls
c
• Keep the nozzle in contact with the rim of the fuel tank or container
opening at all times until the fueling is complete. Do not use a nozzle lock-
open device.
• Never overfill fuel tank. Replace fuel tank cap and tighten securely.
• Replace all fuel container caps securely after use.
• For gasoline engines, do not use gas with methanol. Methanol is harmful
to your health and to the environment.
Handling Waste Product and Chemicals
• Waste products, such as, used oil, fuel, coolant, brake fluid, and
batteries, can harm the environment and people:
• Do not use beverage containers for waste fluids - someone may drink
from them.
• See your local Recycling Center or authorized dealer to learn how to
recycle or get rid of waste products.
• A Material Safety Data Sheet (MSDS) provides specific details on
chemical products: physical and health hazards, safety procedures, and
emergency response techniques. The seller of the chemical products
used with your machine is responsible for providing the MSDS for that
product.

• Deck drive belt slipping or broken.
• Deck belt tension spring not installed
or broken.
• PTO switch faulty.
• Fuse blown.
Preparing Fuel and Engine For Storage
Fuel:
• Loose electrical connections.
• PTO clutch faulty.
If you have been using “Stabilized Fuel,” add stabilized fuel to tank until
the tank is full.
Mower Mows Unevenly
• Mower deck not properly leveled.
• Ground speed too fast for conditions.
• Run engine at fast throttle.
NOTE: Filling the fuel tank reduces the amount of air in the fuel tank
and helps reduce deterioration of fuel.
If you are not using “Stabilized Fuel:”
1. Park machine safely in a well-ventilated area. (See Parking Safely in
the SAFETY section.)
• Reduce ground speed when making
turns.
NOTE: Try to anticipate the last time the machine will be used for the
season so very little fuel is left in the fuel tank.
• Sharpen or replace blades.
• Change mowing pattern.
2. Turn on engine and allow to run until it runs out of fuel.
• Check air pressure in all traction unit
tires.
3. For machines equipped with key switch, turn key to off position.
c
• Anti-scalp rollers not adjusted
correctly.
IMPORTANT: Avoid Damage! Stale fuel can produce varnish and
plug carburetor or injector components and affect engine
performance.
• Add fuel conditioner or stabilizer to fresh fuel before filling tank.
4. Mix fresh fuel and fuel stabilizer in separate container. Follow stabilizer
instructions for mixing.
5. Fill fuel tank with stabilized fuel.
6. Run engine for a few minutes to allow fuel mixture to circulate through
carburetor on gas engine or fuel injectors on diesel engine.
