IMPORTANT
SAFE OPERATION PRACTICES
THIS SYMBOL POINTS OUT IMPORTANT SAFETY INSTRUCTIONS WHICH, IF NOT FOLLOWED,
COULD ENDANGER THE PERSONAL SAFETY AND/OR PROPERTY OF YOURSELF AND
OTHERS. READ AND FOLLOW ALL INSTRUCTIONS IN THIS MANUAL BEFORE ATTEMPTING
TO OPERATE YOUR UNIT. FAILURE TO COMPLY WITH THESE INSTRUCTIONS MAY RESULT
IN PERSONAL INJURY. WHEN YOU SEE THIS SYMBOL—
HEED ITS WARNING.
DANGER
I.
Your lawn mower was built to be operated according to the rules for safe operation
in this manual. As with any type of power equipment, carelessness or error on the
part of the operator can result in injury. This lawn mower is capable of amputating
hands and feet or throwing objects. Failure to observe the following safety
instructions could result in serious injury or death.
5. Be sure the area is clear of other people before
mowing. Stop machine if anyone enters the area.
GENERAL OPERATION
1. Read, understand and follow all instructions in the
manual and on the machine before starting. Keep
this manual in a safe place for future and regular
reference.
6. Never carry passengers.
7. Disengage the blades before shifting into reverse
and backing up. Always look down and behind
before and while backing.
2. Only allow responsible individuals familiar with
the instructions to operate the machine. Know the
controls and how to stop the machine quickly.
8. Be aware of the mower and attachment discharge
direction and do not point it at anyone. Do not
operate the mower without either the entire grass
catcher or the chute guard in place.
3. Do not put hands or feet under the cutting deck or
near rotating parts.
9. Slow down before turning. Operate the machine
smoothly. Avoid erratic operation and excessive
speed.
4. Clear the area of objects such as rocks, toys,
wire, etc. which could be picked up and thrown by
the blades. A small object may have been
overlooked and could be accidentally thrown by
the mower in any direction and cause injury to
you or a bystander. To help avoid a thrown
objects injury, keep children, animals, bystanders
and helpers at least 75 feet from the mower while
it is in operation. Always wear safety glasses with
side shields or safety goggles during operation or
while performing an adjustment or repair, to
protect eyes from foreign objects. Stop the blades
when crossing gravel drives, walks or roads.
10. Never leave a running machine unattended.
Always turn off the blades, place the transmission
in neutral, set the parking brake, stop the engine
and remove key before dismounting.
11. Turn off blades when not mowing.
12. Stop the engine and wait until the blades come to
a complete stop before (a) removing the grass
catcher or unclogging chute, or (b) making any
repairs, adjusting or removing any grass or debris.
4
DO:
13. Mow only in daylight or good artificial light.
14. Do not operate the machine while under the
influence of alcohol or drugs.
Mow across slopes, not up and down.
Remove obstacles such as rocks, limbs, etc.
15. Watch for traffic when operating near or crossing
roadways.
Watch for holes, ruts or bumps. Uneven terrain could
overturn the machine. Tall grass can hide obstacles.
16. Use extra care when loading or unloading the
machine into a trailer or truck. This unit should not
be driven up or down a ramp onto a trailer or truck
under power, because the unit could tip over
causing serious personal injury. The unit must be
pushed manually on a ramp to load or unload
properly.
Use slow speed. Choose a low enough speed so that
you will not have to stop while on the slope.
Follow the manufacturer’s recommendations for counterweights with attachments to improve stability.
Use extra care with grass catchers or other attachments. These can change the stability of the machine.
17. Never make a cutting height adjustment while the
engine is running if the operator must dismount to
do so.
Keep all movement on the slopes slow and gradual.
Do not make sudden changes in speed or direction.
Rapid acceleration or deceleration could cause the
front of the machine to lift and rapidly flip over backwards, which could cause serious injury.
18. Wear sturdy, rough-soled work shoes and closefitting slacks and shirts. Do not wear loose fitting
clothes or jewelry. They can be caught in moving
parts. Never operate a unit in bare feet, sandals
or sneakers.
Avoid starting or stopping on a slope. If the tires lose
traction, disengage the blades and proceed slowly
straight down the slope.
19. Check overhead clearance carefully before driving
under power lines, wires, bridges or low hanging
tree branches, before entering or leaving
buildings, or in any other situation where the
operator may be struck or pulled from the unit,
which could result in serious injury.
DO NOT:
Do not turn on slopes unless necessary; if mowing
slopes, turn slowly and gradually uphill, if possible.
Do not mow near drop-offs, ditches or embankments.
The mower could suddenly turn over if a wheel is over
the edge of a cliff or ditch, or if an edge caves in.
20. Disengage all attachment clutches, set the
parking brake in the on position, and put the lap
bars to the neutral or out position before
attempting to start the engine.
Do not mow on wet grass. Reduced traction could
cause sliding.
21. Your mower is designed to cut normal residential
grass of a height no more than 10”. Do not
attempt to mow through unusually tall, dry grass
(e.g. pasture) or piles of dry leaves. Debris may
build up on the mower deck or contact the engine
exhaust presenting a potential fire hazard.
Do not try to stabilize the machine by putting your foot
on the ground.
Do not use the grass catcher on steep slopes.
III. CHILDREN
22. Use only accessories approved for this machine
by Troy-Bilt. Read, understand and follow all
instructions provided with the approved
accessory.
Tragic accidents can occur if the operator is not alert
to the presence of children. Children are often
attracted to the machine and the mowing activity.
Never assume that children will remain where you
last saw them.
II. SLOPE OPERATION
1. Keep children out of the mowing area and in
watchful care of an adult other than the operator.
Slopes are a major factor related to loss of control and
tip-over accidents, which can result in severe injury or
death. All slopes require extra caution. If you cannot
back up the slope or if you feel uneasy on it, do not
mow it.
2. Be alert and turn the machine off if children enter
the area.
3. Before and when backing up, look behind and
down for small children.
For your safety, use the slope gauge included as part
of this manual to measure slopes before operating this
unit on a sloped or hilly area. If the slope is greater than
15° as shown on the slope gauge, do not operate this
unit on that area or serious injury could result.
4. Never carry children, even with the blades off.
They may fall off and be seriously injured or may
interfere with safe machine operation.
5
8. After striking a foreign object, stop the engine,
remove the wire from the spark plug and
thoroughly inspect the mower for any damage.
Repair the damage before restarting and
operating the mower.
5. Never allow children under 14 years old to
operate the machine. Children 14 years and over
should only operate the machine under close
parental supervision and proper instruction.
6. Use extra care when approaching blind corners,
shrubs, trees or other objects that may obscure
your vision of a child or other hazard.
9. Grass catcher components are subject to wear,
damage and deterioration, which could expose
moving parts or allow objects to be thrown. For
your safety protection, frequently check the
components and replace with manufacturer’s
recommended parts when necessary.
7. Remove the key when the machine is left
unattended to prevent unauthorized operation.
IV. SERVICE
1. Use extreme care in handling gasoline and other
fuels. They are extremely flammable and the
vapors are explosive.
10. Mower blades are sharp and can cut. Wrap the
blades or wear gloves, and use extra caution
when servicing blades.
a. Use only an approved container.
b. Never remove fuel cap or add fuel with the engine running. Allow the engine to cool at least
two minutes before refueling.
c. Replace the fuel cap securely and wipe off any
spilled fuel before starting the engine as it may
cause a fire or explosion.
d. Extinguish all cigarettes, cigars, pipes and other sources of ignition.
e. Never refuel the machine indoors because fuel
vapors will accumulate in the area.
f. Never store the fuel container or machine
inside where there is an open flame or spark,
such as a gas hot water heater, space heater
or furnace.
11. Check the park brake operation frequently. Adjust
and service as required.
12. Muffler, engine and belt guards become hot
during operation and can cause a burn. Allow to
cool down before touching.
13. Do not change the engine governor settings or
overspeed the engine. Excessive engine speeds
are dangerous.
14. Observe proper disposal laws and regulations.
Improper disposal of fluids and materials can
harm the environment and the ecology.
a. Prior to disposal, contact your local
Environmental
Protection
Agency
to
determine the proper method for disposing of
the waste. Recycling centers are established
to properly dispose of materials in an
environmentally safe fashion.
2. Never run a machine inside a closed area.
3. To reduce fire hazard, keep the machine free of
grass, leaves or other debris build-up. Clean up
oil or fuel spillage. Allow the machine to cool at
least 5 minutes before storing.
b. Use proper containers when draining fluids.
Do not use food or beverage containers that
may mislead someone into drinking from
them. Properly dispose of the containers immediately following the draining of fluids.
4. Before cleaning, repairing or inspecting, make
certain the blade and all moving parts have
stopped. Disconnect the spark plug wire, and
keep the wire away from the spark plug to prevent
accidental starting.
c.
5. Check the blade and engine mounting bolts at frequent intervals for proper tightness. Also visually
inspect blades for damage (e.g., excessive wear,
bent, cracked). Replace with blades which meet
original equipment specifications.
DO NOT pour oil or other fluids into the
ground, down a drain or into a stream, pond,
lake, or other body of water. Observe Environmental Protection Agency regulations when
disposing of oil, fuel, coolant, brake fluid, filters, batteries, tires and other harmful waste.
15. We do not recommend the use of a pressure
washer or garden hose to clean your unit. They
may cause damage to electrical components;
spindles; pulleys; bearings; or the engine. The
use of water will result in shortened life and
reduce serviceability.
6. Keep all nuts, bolts and screws tight to be sure
the equipment is in safe working condition.
7. Never tamper with safety devices. Check their
proper operation regularly. Use all guards as
instructed in this manual.
WARNING - YOUR RESPONSIBILITY: Restrict the use of this power machine to persons who
read, understand and follow the warnings and instructions in this manual and on the machine.

•
•
•
•
•
Before you operate the tractor, study this manual
carefully to familiarize yourself with the operations of all the instruments and controls. It has
been prepared to help you operate and maintain
your tractor efficiently.
• Familiarize yourself with the operations of all the
instruments and controls.
• This engine is certified to operate on unleaded
gasoline. For best results, fill the fuel tank with
only clean, fresh, unleaded gasoline with a pump
sticker octane rating of 87 or higher. In countries
using the Research method, it should be 90
octane minimum.
• Unleaded gasoline is recommended because it
leaves less combustion chamber deposits and
reduces harmful exhaust emissions. Leaded
gasoline is not recommended and must not be
used where exhaust emissions are regulated.
NOTE: Purchase gasoline in small quantities. Do not
use gasoline left over from the previous season, to
minimize gum deposits in the fuel system.
• Gasohol (up to 10% ethyl alcohol, 90% unleaded
gasoline by volume) is an approved fuel. Other
gasoline/alcohol blends are not approved.
• Methyl Tertiary Butyl Ether (MTBE) and unleaded
gasoline blends (up to a maximum of 15% MTBE
by volume) are approved fuels. Other gasoline/
ether blends are not approved.
• Check the engine oil level.
• Clean the air cleaner element if necessary. See
Engine Manual.
• Check the tire inflation pressures.
• Adjust the seat for operator’s maximum comfort,
visibility, and for maintaining complete control of
the tractor.
RECEIVE INSTRUCTION - Read the operator’s
manual. Learn to operate this machine SAFELY.
Don’t risk INJURY or DEATH. Allow only those
who have become competent in its usage to
operate this tractor .
Familiarize yourself with the operations of all the
instruments and controls.
Before starting the engine or beginning operation,
be familiar with the controls. The operator should
be in the operator’s seat. The PTO switch must
be in the disengaged position, the parking brake
engaged, and the RH and LH drive control levers
moved fully outward in the neutral position.
Keep all shields in place. Keep away from moving
parts.
NO RIDERS! Keep all people and pets a safe
distance away. Look behind and down to both
sides of the tractor before and while backing up.
DO NOT direct the mower discharge at people.
Avoid slopes where possible. Never operate on
slopes greater than 15°. Slopes with a greater
incline present dangerous operating conditions.
Tractors can be rolled over.
Before leaving the operator’s seat: Shut off the
PTO, move the RH and LH drive control levers
fully outward in the neutral position, engage the
parking brake, shut off the engine and remove
the ignition key. Wait for all movement to stop
before servicing or cleaning.
Operate the drive control levers smoothly and
avoid any sudden movements of the levers
when starting and stopping. Keep a firm grip on
the control levers; do not allow the levers to
return to neutral on their own.
Be careful when operating near roadways. Stop
the tractor motion and wait for vehicles to pass
before operating along the road.
Do not operate the tractor with the mower deck
removed. Removal of the deck will change the
balance of the tractor, and could contribute to a
tractor rollover.
Avoid operation on traction surfaces that are
unstable; use extreme caution if the surface is
slippery.
Slow down before turning and come to a
complete stop before any zero turn maneuver.
Do not stop the tractor or park the tractor over
combustible materials such as dry grass, leaves,
debris, etc.
Do not fill the fuel tank when the engine is
running or while the engine is hot. Allow the
engine several minutes to cool before refueling.
Tighten the fuel cap securely.
SAFETY INTERLOCK SYSTEM
This tractor is equipped with a safety interlock system
for the protection of the operator. If the interlock system
should ever malfunction, do not operate the tractor.
Contact your authorized Troy-Bilt Service Dealer.
• The safety interlock system prevents the engine
from cranking or starting unless the RH and LH
drive control levers are moved fully outward in the
neutral position, the parking brake is engaged,
and the PTO is disengaged.
• To avoid sudden movement when disengaging
the parking brake, the safety interlock system will
shut off the engine if the RH and/or LH drive
control levers are moved to a position other than
the fully out in neutral position when the parking
brake is engaged
15
•
The safety interlock system will shut off the
engine if the operator leaves the seat before
engaging the parking brake.
•
Pull the choke control knob upward to the full
choke position. NOTE: If the engine is warmed
up, it may not be necessary to choke the engine.
•
The safety interlock system will shut off the
engine if the operator leaves the seat with the
PTO engaged, regardless of whether the parking
brake is engaged.
NOTE: The PTO switch must be moved to the
“OFF” position to restart the engine.
•
Move the throttle control to midway between its
SLOW and FAST positions.
Turn the ignition key clockwise to the “START”
position and release it as soon as the engine
starts; however, do not crank the engine continuously for more than 10 seconds at a time. If the
engine does not start within this time, turn the key
to “OFF” and wait a minute to allow the engine’s
starter motor to cool. Try again after waiting. If
after a few attempts the engine fails to start, do
not keep trying to start it with the choke closed as
this will cause flooding and make starting more
difficult.
•
•
The safety interlock system will shut off the PTO
and the mower blades will stop if both drive control levers are moved into the reverse position.
The PTO will re-engage when one or both of the
levers are moved back to the neutral or forward
position.
STARTING THE ENGINE
WARNING: This unit is equipped with a
safety interlock system designed for the
protection of the operator. Do not operate the tractor if any part of the interlock
system is malfunctioning. Periodically

PRACTICE OPERATION (INITIAL USE)
Operating a zero-turn tractor is not like operating a
conventional type riding tractor. Although and because a zero-turn tractor is more maneuverable, getting used to operating the control levers takes some
practice.
Figure 11
NOTE: If the control levers are not even in the neutral
position, refer to Section 3 and adjust the levers so
that they are even.
We strongly recommend that you locate a reasonably large, level and open "practice area" where there
are no obstructions, pedestrians, or animals. You
should practice operating the tractor for a minimum of
30 minutes.
•
Move the throttle control lever forward to the full
throttle position (3500-3600 RPM).
NOTE: The tractor and engine are designed to run at
full throttle. If performing a practice session, it is
preferable that the tractor is operated at less than full
throttle (approximately 2500-3000 RPM), but this only
applies to practice operation.
Carefully move (or have moved) the tractor to the
practice area. When performing the practice session,
the PTO should not be engaged. While practicing,
operate the tractor at approximately 1/2-3/4 throttle
and at less than full speed in both forward and
reverse.
WARNING: Always maintain a firm grip
on the control levers. DO NOT release the
control levers to slow or stop the tractor;
move the levers to the neutral position
using your hands.
Carefully practice maneuvering the tractor using the
instructions in the following section "Driving the Tractor." Practice until you are confident that you can
safely operate the tractor.

- Turn the ignition switch to “OFF’” and remove
the key from the switch.
Executing a Zero Turn
WARNING: When executing a zero turn,
the tractor MUST BE STOPPED.
Executing a zero turn while the tractor is
moving can significantly reduce your
control of the tractor and will cause
severe turf defacement to occur.
•
Stop the forward or reverse motion of the tractor
by moving the two drive control levers to neutral.
•
To turn clockwise, slowly move the left control
lever forward while simultaneously moving the
right control lever rearward. See Figure 18.
CLOCKWISE ZERO TURN
DRIVING ON SLOPES
Refer to the SLOPE GAUGE on page 10 to help
determine slopes where you may not operate safely.
WARNING: Do not operate on inclines
with a slope in excess of 15 degrees (a
rise of approximately 2-1/2 feet every 10
feet). The tractor could overturn and
cause serious injury.
•
Figure 18
•
•
To turn counterclockwise, slowly move the right
control lever forward while simultaneously moving
the left control lever rearward. See Figure 19.
•
COUNTERCLOCKWISE ZERO TURN
Always drive across slopes, never up and down.
Control the speed and direction of the tractor
using primarily the control lever on the downhill
side of the tractor, with the uphill control lever
remaining essentially in a fixed position.
Avoid turning downhill if possible. Start at the
bottom of a slope and work upward. Always slow
down before turning.
Use extra care and go slowly when turning
downhill.
OPERATING THE PTO
Operate the PTO clutch as follows:
• Move the throttle control lever to approximately
the mid throttle position.
• Pull the PTO switch upward to the “ENGAGED”
position.
• Advance the throttle lever to the operating speed
(full engine speed).
• The operator must remain in the tractor seat at all
times. If the operator should leave the seat
without turning off the power take-off switch, the
tractor’s engine will shut off.
• The PTO clutch cannot be operated when the
tractor is driving in the reverse direction. The
PTO will disengage when both drive control
levers are moved to the reverse position, and will
re-engage when one (or both) control levers are
moved to the neutral or forward position.

IMPORTANT: When stopping the tractor for any
reason while on a grass surface, always:
USING THE MOWER DECK
WARNING: Make certain the area to be
mowed is free of debris, sticks, stones,
wire or other objects that can be thrown
by the rotating blades.
• Place the shift lever in neutral,
• Engage the parking brake,
• Shut engine off and remove the key.
Doing so will minimize the possibility of having your
lawn ‘‘browned’’ by hot exhaust from your tractor’s
running engine.
IMPORTANT: Do not engage the mower deck
when lowered in grass. Premature wear and
possible failure of the ‘V” belt and PTO clutch will
result. Fully raise the deck or move to a non
grassy area before engaging the mower deck.
•
Mow across slopes, not up and down. If mowing
a slope, start at bottom and work upward to
ensure turns are made uphill.
•
On the first pass pick a point on the opposite side
of the area to be mowed.
•
Engage the PTO clutch using the PTO switch and
move the throttle control to the fast position.
•
Lower the mower deck to the desired height
setting using the lift handle.
•
Slowly and evenly push the RH and LH drive
control levers forward to move the tractor
forward, and keep the tractor headed directly
toward the alignment point.
NOTE: The speed of the tractor will affect the
quality of the mower cut. Mowing at full speed will
adversely affect the cut quality. Control the
ground speed with the control levers.
•
When approaching the other end of the strip,
slow down or stop before turning. A U-turn is
recommended unless a pivot or zero turn is
required.
•
Align the mower with an edge of the mowed strip
and overlap approximately 3 inches.
•
Direct the tractor on each subsequent strip to
align with a previously cut strip.
•
To prevent rutting or grooving of the turf, if
possible, change the direction that the strips are
mowed by approximately 45° for the next and
each subsequent mowing.
CHECKING THE SAFETY INTERLOCK CIRCUITS
Periodically check the safety interlock circuits to
ensure they are working properly. If a safety circuit is
not working as designed, contact you authorized
Troy-Bilt Service Dealer to have the tractor inspected.
DO NOT operate the tractor if any safety circuit is not
functioning properly. To check the safety circuits,

necessary to remove the battery.
•
All batteries discharge during storage. Keep the
exterior of the battery clean, especially the top. A
dirty battery will discharge more rapidly.
The battery must be stored with a full charge. A
discharged battery can freeze sooner than a
charged battery. A fully charged battery will store
longer in cold temperatures than hot.
Recharge the battery before returning to service.
Although the tractor may start, the engine charging
system may not fully recharge the battery.
•
Install the battery by repeating the above steps in the
reverse order.
WARNING: Always connect the positive
lead to the battery before connecting the
negative lead. This will prevent sparking
or possible injury from an electrical short
caused by contacting the tractor body with
tools being used to connect the cables.
•
SERVICING ELECTRICAL SYSTEM
A fuse is installed to protect the tractor’s electrical
system from damage caused by excessive amperage. Always use the same capacity fuse for
replacement. If the electrical system does not function, check for a blown fuse. See Figure 24
If you have a recurring problem with blown fuses,
have the tractor’s electrical system checked by your
authorized Troy-Bilt Service Dealer.
CHARGING THE BATTERY
Test and, if necessary, recharge the battery after the
tractor has been stored for a period of time.
• A voltmeter or load tester should read 12.6 volts
(DC) or higher across the battery terminals.
•
Charge the battery with a 12-volt battery charger
at a MAXIMUM rate of 10 amps.

BATTERY MAINTENANCE
There are several safety switches in the electrical
system. If a function of the safety interlock system
described earlier is not functioning properly, have the
electrical system checked by your authorized TroyBilt Service Dealer.
The battery is filled with battery acid and then sealed
at the factory. However, even a “maintenance free”
battery requires some maintenance to ensure its
proper life cycle.
•
Spray the terminals and exposed wire with a
battery terminal sealer, or coat the terminals with
a thin coat of grease or petroleum jelly, to protect
against corrosion.
•
Always keep the battery cables and terminals
clean and free of corrosion.
•
Avoid tipping. Even a sealed battery will leak
electrolyte when tipped.
LUBRICATION
24
•
Using a pressure lubricating gun, lubricate the
front castor axles and pivot axle with a No. 2
multi-purpose grease after every 10 hours of
service.
•
Refer to the "MOWER DECK" section later in this
manual for deck lubrication procedures.
•
Periodically lubricate all other pivot points with a
quality lubricating oil.
IMPORTANT: The tractor will not drive with the
bypass rods in the engage position.
TIRE MAINTENANCE
Check the tire air pressure after every 50 hours of
operation or weekly. Keep the tires inflated to the
recommended pressures. Improper inflation will
shorten the service life of a tire. See the tire side wall
for proper inflation pressures. Observe the following
guidelines:
•
Do not inflate a tire above the maximum pressure
shown on the sidewall of the tire.
•
Do not reinflate a tire that has been run flat or
seriously under inflated. Have a qualified tire
mechanic inspect and service the tire.
TRACTOR CREEPING
Creeping is the slight forward or backward movement
of the tractor when the engine is running at high idle
and the drive control levers are opened out in the
neutral position.
If after operating the tractor for some time, it begins to
creep while in the neutral position, adjust the
transmission control rods as follows.
USING THE TRANSMISSION BYPASS RODS
If for any reason the tractor will not drive or you wish
to move the tractor, the two hydrostatic transmissions are equipped with a bypass rod that will allow
you to manually move the tractor short distances.
WARNING: Do not tow the tractor, even
with the bypass rod engaged. Serious
transmission damage will result from
doing so.
•
•
Place the front of the tractor against an
immovable object (e.g. wall, post, etc.).
•
Jack up the rear of the tractor so that both rear
wheels are approximately one inch of the ground.
•
With the engine running at high idle and the drive
control levers opened out in the neutral position,
and the parking brake disengaged, check the rear
wheels for rotation.
•
If only one wheel is rotating, locate the transmission control rod beneath the frame at the front of
the rear tire. If both wheels rotate, locate both
control rods. See Figure 26.
From just in front of the two rear tires, locate the
transmission bypass rods. See Figure 25.

•
Remove the internal cotter pin securing the
ferrule to the transmission control arm and
withdraw the ferrule. Wheel rotation should stop.
If it does not, contact your authorized Troy-Bilt
Service Dealer.
•
If the rotation stops, adjust the ferrule up or down
the control rod as necessary to align with the hole
in the transmission control arm. Re-insert the
ferrule into the hole in the control arm and secure
with the internal cotter pin.
•
If necessary, repeat the previous two steps to
adjust the other transmission control rod.
•
Lower the tractor and remove the jack.
TRACTOR HIGH SPEED TRACKING
TRANSMISSION DRIVE BELT
If the tractor tracks to one side with both drive control
levers fully forward, adjust the control levers as
follows:
If the transmission drive belt becomes worn and
causes the drive transmissions to slip, the drive belt
must be replaced. To replace the drive belt, proceed
as follows:
•
•
Check for proper and balanced air pressure in
both front and rear tires. Refill tires if necessary.
Perform the first three steps in the previous subsection, Tractor Creeping, to verify that the tractor
is not creeping. If creeping, adjust following the
instructions in that sub-section.
•
Recheck the tracking after making any adjustments to the transmission control rods.
•
If uneven tracking persists, note which direction
the tractor is tracking.

LEVELING THE MOWER DECK
When correctly adjusted the mower deck should be
level side to side, and the front of the deck should be
approximately 1/4 inch lower than the rear of deck.
Side to Side Leveling
If the cutting deck appears to be mowing unevenly, a
side to side adjustment can be performed. Adjust if
necessary as follows:
•
With the tractor parked on a firm, level surface,
place the deck lift handle in the top notch (highest
position) and rotate both outer blades so that they
are perpendicular to the tractor frame.
•
Lower the deck to the middle height position.
•
Measure the distance from the outside left blade
tip to the ground and the distance from the
outside right blade tip to the ground. The
measurements should be equal. If they’re not,
proceed to the next step.
•
Comparing the two measurements, determine
whether the left side of the deck must be raised
or lowered.
•
Loosen, but do not remove, the hex cap screw on
the left deck hanger bracket. Refer to Figure 32.
•
Level the deck by using a wrench to turn the
adjustment gear (found immediately behind the
hex cap screw just loosened) clockwise to raise
the left side of the deck, or counterclockwise to
lower the left side of the deck. See Figure 32.
•
With the deck raised off of the ground, rotate the
outer blades so that they are parallel to the frame
of the tractor.
•
If the side to side leveling was done correctly,
measuring just the right blade should be
acceptable to attain the correct back to front pitch
of the deck.
•
Measure the distance from the front tip of the
blade to the ground and the distance from the
rear tip to the ground. The front distance should
be approximately 1/4 inch less than the rear. If it
is not, proceed to the next step.
•
From the front of the tractor, loosen the outer
nuts on the deck front hanger rod, and turn them
away from the inner nuts. See Figure 33.

achieved.
If the front of the deck was too low, turn the inner
hex nuts clockwise against the hanger bracket to
shorten the front hanger rod and raise the front of
the deck. See Figure 33.
•
If the front of the deck was too high, turn the hex
nuts counterclockwise to lengthen the front
hanger rod and lower the front of the deck.
IMPORTANT: The deck front hanger rod should
be at the front of the slots of the front deck
bracket. If one side of the rod is not at the front of
its slot, turn the inner hex nut on that side until
rod just touches the front of the slot. Then remeasure and re-adjust the front hanger rod as
necessary.
