SAFETY INSTRUCTIONS
Driving on Slopes
Driving on slopes is one of the operations where
the risk is greatest that the driver will lose control
or the machine will tip over, which can result in
serious injury or death. All slopes require extra
caution. If you cannot reverse up a slope or if feel
unsure, do not mow the slope.
Do as follows:
• Remove obstacles such as stones, tree
branches, etc.
• Mow up and down, not side-to-side.
• Never drive the rider on terrain that slopes
more than 10°.
• Avoid starting or stopping on a slope, If the
tires begin to slip, shut down the blades and
drive slowly down the slope.
• Always drive evenly and slowly on slopes.
6003-004
Mow up and down, not side-to-side.
• Make no sudden changes in speed or direc-
tion.
• Avoid unnecessary turns on slopes, and if it
proves necessary, turn slowly and gradually
downward, if possible.
• Watch out for and avoid driving over furrows,
holes, and bumps. On uneven terrain, the
machine can tip more easily. Long grass can
hide obstacles.
• Drive slowly. Use small movements of the
steering controls.
• Be extra cautious with any additional equip-
ment, which can alter the machine’s stability.
• Do not mow near verges, ditches, or banks.
The machine can suddenly spin around if a
wheel goes over the edge of a drop or ditch,
or if an edge gives way .
• Do not mow wet grass. It is slippery, and the
tires can lose their grip, so that the machine
slides.
8011-519
Be extra cautious when driving on slopes.
• Avoid starting or stopping on a slope. If tires
lose traction, disengage the blades and proceed slowly straight down the slope.
• If machine stops while going uphill, disengage
blades and back down slowly.
• Try not to stabilize the machine by putting a
foot on the ground.
• When cleaning the chassis, the machine may
never be driven near verges or ditches.
• Do not turn on slopes unless necessary, and
then, turn slowly and gradually downhill, if possible.

SAFETY INSTRUCTIONS
Children:
• Serious accidents may occur if you fail to be
on guard for children in the vicinity of the machine. Children are often attracted to the machine and mowing work. Never assume that
children will stay put where you last saw them.
• Keep children away from the mowing area and
under close supervision by another adult.
• Keep an eye out and shut off the machine if
children enter the work area.
• Before and during a reversing maneuver, look
backward and downward for small children.
• Never allow a child to ride with you. They can
fall off and injure themselves seriously or prevent risk-free maneuvering of the machine.
• Never allow children to operate the machine.
• Be particularly cautious near corners, bushes,
trees, or other objects that block your view.
Maintenance:
W ARNING!
The engine must not be started when the driver’s floor plate or any protective
plate for the mower deck’s drive belt is removed.
• Stop the engine. Prevent the engine from st art-
ing by removing the ignition key before making any adjustments or performing maintenance.
• Never fill the fuel tank indoors.
8011-517
Never allow children to operate the machine.
• Fuel and fuel fumes are poisonous and ex-
tremely flammable. Be especially cautious
when handling fuel, as carelessness can result in personal injury or fire.
• Only store fuel in containers approved for the
purpose.
• Never remove the fuel tank cap and never fill
the fuel tank while the engine is running.
10
8011-516
Never fill the fuel tank indoors.
Page 11
SAFETY INSTRUCTIONS
• Allow the engine to cool before refueling. Do
not smoke. Do not fill fuel in the vicinity of
sparks or open flames.
• If leaks arise in the fuel system, the engine
must not be started until the problem has been
resolved.
• Store the machine and fuel in such a way that
there is no risk of leaking fuel or fuel vapor
leading to damages.
• Check the fuel level before each use and leave
space for the fuel to expand, because the heat
from the engine and the sun may otherwise
cause the fuel to expand and overflow .
• Avoid overfilling. If you spill fuel on the machine,
wipe up the spill and wait until it has evaporated before starting the engine. If you have
spilled fuel on your clothing, change your
clothing.
• Allow the machine to cool before taking any
actions in the engine compartment.
• Be very careful when handling battery acid.
Acid on skin can cause serious corrosive
burns. If you spill battery acid on your skin,
rinse immediately with water.
W ARNING!
The engine, the exhaust system,
and the hydraulic system’s components become very warm during
operation.
Risk for burns if touched.
WARNING!
The battery contains lead and lead
compounds, chemicals that are
considered to cause cancer, birth
defects, and other reproductive
system damage.
Wash your hands after touching the
battery.
• Acid in the eyes can cause blindness, con-
tact a doctor immediately.
• Be careful when servicing the battery . Explo-
sive gases form in the battery . Never perform
maintenance on the battery when smoking or
near open flames or sparks. The battery can
explode and cause serious injury/damage.
• Ensure that nuts and bolts, especially the fas-
tening bolts for the blade attachments, are
properly tightened and that the equipment is
in good condition.
• Do not modify safety equipment. Check regu-
larly to be sure it works properly . The machine
must not be driven with defective or unmounted protective plates, protective cowlings, safety switches, or other protective devices.
• Do not change the settings of governors and
avoid running the engine with overly high engine speed. If you run the engine too fast, you
risk damaging the machine components.

Motion Control Levers
The machine’s speed and direction are
continuously variable using the two motion control
levers. The motion control levers can be moved
forward or backward from a neutral position.
Furthermore, there is a neutral position, which is
locked if the motion control levers are moved
outward into the neutral slots.
When both controls are in the neutral position (N),
the machine stands still.
The motion control levers on each side of the
mower control the direction of movement. The left
lever controls the flow of oil from the left hydro pump
to the left wheel motor . The right lever controls the
flow of oil from the right hydro pump to the right
wheel motor.
NOTE: To begin motion, the operator must be in
the seat and the parking brake disengaged before
the motion control levers can be moved from the
neutral slots or the engine will shut down.
By moving the levers an equal amount forward or
back the machine will move in a straight line in
that direction.

Mowing Tips
W ARNING!
Clear the lawn of stones and other
objects that can be thrown out by
the blades.
• Locate and mark rocks and other fixed objects
in order to avoid collisions.
• Begin with a high cutting height and reduce it
until the desired mowing result is attained.
• The mowing result will be best with a high
engine speed (the blades rotate rapidly) and
low speed (the rider moves slowly). If the grass
is not too long and
Mowing patterns
B8011-603
31
Page 32
OPERATION
dense, the driving speed can be increased
without noticeably depreciating the mowing
result.
• The finest lawns are obtained by mowing often.
The mowing becomes more even and the
grass clippings more evenly distributed over
the mown area. The total time taken is not
increased as a higher driving speed can be
used without poorer mowing results.
• Avoid mowing wet lawns. The mowing result
is poorer because the wheels sink into the soft
lawn, clumps build, and the grass clippings
attach under the deck.
• Hose beneath the mower deck with water after
each use. When cleaning, the mower deck
should be raised into the transport position.
• When the mulch deck is used, it is extremely
important that the mowing interval is not too
long.
W ARNING!
Never drive the machine on terrain that slopes more than 10°.
Mow slopes up and down, never
side-to-side. Avoid sudden directional changes.
Transport & Extended Periods of
Inactivity
On units equipped with the hydraulic deck lift
system, it is recommended the deck be lowered
against the stop pin during transport or extended
periods of inactivity .

FUEL FIL TER
BAM-18
NOTE: Failure to follow the recommended
procedure for filling the cooling system will cause
engine overheating and possible engine failure.
ALWAYS check coolant level at the overflow
reservoir. The correct level of coolant in the over
flow tank does NOT assure the radiator is full.
It is extremely important that when antifreeze is
used, that it be mixed with water in a separate
container before adding. NEVER add straight
antifreeze to the radiator. Recommended mix is
50/50 lowtox (propylene glycol) phosphate-free
antifreeze with tap water. DO NOT mix in ethylene
glycol. Refer to engine operator’s manual.
The radiator for this cooling system is provided
with two drain valves; one at each end of the lower
tank. When draining the system, it is necessary to
open both these valves to drain the radiator
completely.
Add coolant to the radiator until it is up to the bottom
of the fill cap. DO NOT install cap.
If the block has been drained, start and run the
en-gine until the coolant level in the radiator drops.
Stop engine.

MAINTENANCE
When refilling the system, it is important that all
trapped air be purged. The following procedure will
help to insure this:
1. Make sure the engine is level. Fill the overflow
reservoir up to the MAX mark with coolant
mixture.
2. Slowly fill the radiator to the bottom of the filler
neck with coolant mixture.
3. With radiator cap off, start the engine and let
it warm up (no-load). Then, if necessary, add
more coolant mixture to bring the level back
up to the bottom of the filler neck.
4. Reinstall the radiator cap and run the engine
a short time with the system sealed while
watching the temperature gauge. If the
temperature gauge goes past 230 degrees
and does not drop back to approximately 190
degrees, indicating the thermostat has opened,
allow the engine to cool down, check for leaks
and repeat the procedure.
Overflow bottle
BAM-20
This is a sealed system. If it becomes necessary
to add coolant mixture at a later date, check for
leaks and if the overflow reservoir has not been
drained completely, add coolant mixture to the
reservoir only . This will help prevent air pockets in
the radiator top tank and lessen the chance of
introducing contaminates to the system.
Checking the Parking Brake
Visually check that no damage is found on the
lever, links, or switch belonging to the p arking brake.
Perform a test drive and check that there is a
braking effect.
To adjust the parking brake:
1. Set brake lever (D) fully forward against stop.
NOTE: Brake cross shaft MUST be properly
lubricated and both cross shaft and over-center
assemblies (F) MUST rotate freely.
2. Loosen jam nut (A) at rear of clevis (B) and
remove clevis pin (C) both sides of mower.

Caster Wheels
Check every 200 hours. Lift front of unit off of
ground so caster wheels can rotate freely . T ighten
caster bolt then back off 1/2 turn. Check that wheel
rotates freely . If wheel does not rot ate freely back
the caster bolt off in 1/4 turn increments until wheel
rotates freely.
NOTE: DO NOT add any type of tire liner or foam
fill material to the tires. Excessive loads created
by foam filled tires will cause premature failures.

General
Remove the ignition key to prevent unintentional movements during lubrication.
When lubricating with an oil can, it should be filled with engine oil.
When lubricating with grease, unless otherwise stated, a lithium based grease or another chassis or
ball bearing grease, offering good corrosion protection should be used.
With daily use, the machine should be lubricated twice weekly.
Wipe away excess grease after lubrication.
It is important to avoid getting lubricant on the belts or the drive surfaces on the belt pulleys. Should
this happen, attempt to clean them with spirits. If the belt continues to slip after cleaning with spirits, it
must be replaced. Gasoline or other petroleum products must not be used to clean belts.

LUBRICATION
Lubricating the Cables
If possible, grease both ends of the cable and move the controls to end stop positions when lubricating.
Refit the rubber covers on the cable after lubrication. Cables with sheaths will bind if they are not lubricated
regularly . If a cable binds, it can disrupt operation.
If a cable binds, remove the cable and hang it vertically . Lubricate it with thin engine oil until the oil begins
to escape from the bottom.
Tip: Fill a small plastic bag with oil and tape it so that it seals against the sheath and allow the cable to
hang vertically from the bag overnight. If you do not succeed in lubricating the cable, it must be replaced.
