Safety Rules & Information
Operating Safety
Congratulations on purchasing a superior-quality piece of lawn and
garden equipment. Our products are designed and manufactured to
meet or exceed all industry standards for safety.
Power equipment is only as safe as the operator. If it is misused, or
not properly maintained, it can be dangerous! Remember, you are
responsible for your safety and that of those around you.
Use common sense, and think through what you are doing. If you
are not sure that the task you are about to perform can be safely
done with the equipment you have chosen, ask a
professional: contact your local authorized dealer.
Read the Manual
The operator’s manual contains important safety information you need to be aware of
BEFORE you operate your unit as well as DURING operation.
Safe operating techniques, an explanation of the product’s features and
controls, and maintenance information is included to help you get the
most out of your equipment investment.
Be sure to completely read the Safety Rules and Information found on
the following pages. Also completely read the Operation section.
Children
Reverse
Tragic accidents can occur with children. Do not allow
them anywhere near the area of operation. Children are
often attracted to the unit and mowing activity. Never
assume that children will remain where you last saw them.
If there is a risk that children may enter the area where you
are mowing, have another responsible adult watch them.
Do not mow in reverse unless
absolutely necessary. Always look
down and behind before and
while traveling in reverse
even with the mower
blades disengaged.
DO NOT GIVE CHILDREN RIDES ON THIS UNIT! This
encourages them to come near the unit in the future while it
is running, and they could be seriously hurt. They may then
approach the unit for a ride when you are not expecting it,
and you may run over them.
TP 600-2459-08-UV-SMA

Safety Rules and Information
Slope Operation
You could be seriously injured or even killed if you use this unit on too
steep an incline. Using the unit on a slope that is too steep or where
you don’t have adequate traction can cause you to lose control or roll
over.
A good rule of thumb is to not operate on any slope you cannot back up
(in 2-wheel drive mode). You should not operate on inclines with a
slope greater than a 3.5 foot rise over a 20 foot length. Always drive up
and down slopes: never cross the face.
Also note that the surface you are driving on can greatly impact stability
and control. Wet grass or icy pavement can seriously affect your ability
to control the unit.
If you feel unsure about operating the unit on an incline, don’t do it. It’s
not worth the risk.
Moving Parts
This equipment has many moving parts that can injure you or someone else.
However, if you are seated in the seat properly, and follow all the rules in this
book, the unit is safe to operate.
The mower deck has spinning mower blades that can amputate hands and feet.
Do not allow anyone near the equipment while it is running!
To help you, the operator, use this equipment safely, it is equipped with an
operator-present safety system. Do NOT attempt to alter or bypass the system.
See your dealer immediately if the system does not pass all the safety interlock
system tests found in this manual.
Thrown Objects
This unit has spinning mower blades. These blades can pick up and throw
debris that could seriously injure a bystander. Be sure to clean up the area to
be mowed BEFORE you start mowing.
Do not operate this unit without the entire grass catcher or discharge guard
(deflector) in place.
Also, do not allow anyone in the area while the unit is running! If someone
does enter the area, shut the unit off immediately until they leave.
Fuel and Maintenance
Gasoline is extremely flammable. Its vapors are also extremely flammable
and can travel to distant ignition sources. Gasoline must only be used as a
fuel, not as a solvent or cleaner. It should never be stored any place where
its vapors can build up or travel to an ignition source like a pilot light. Fuel
belongs in an approved, plastic, sealed gas can, or in the tractor fuel tank
with the cap securely closed. Spilled fuel needs to be cleaned up immedi-
ately.
Proper maintenance is critical to the safety and performance of your unit.
Be sure to perform the maintenance procedures listed in this manual, espe-
cially periodically testing the safety system.

adjustment can be made from the operator’s posi-
tion).
25. When the machine is parked, stored, or left unattend-
ed, lower the cutting means unless a positive
mechanical lock is used.
26. Before leaving the operator’s position for any reason,
engage the parking brake (if equipped), disengage
the PTO, stop the engine, and remove the key.
27. To reduce fire hazard, keep the unit free of grass,
leaves, & excess oil. Do not stop or park over dry
leaves, grass, or combustible materials.
28. It is a violation of California Public Resource Code
Section 4442 to use or operate the engine on or near
any forest-covered, brush-covered, or grass-covered
land unless the exhaust system is equipped with a
spark arrester meeting any applicable local or state
laws. Other states or federal areas may have similar
laws.
8. Never direct discharge material toward anyone.
Avoid discharging material against a wall or obstruc-
tion. Material may ricochet back toward the operator.
Stop the blade(s) when crossing gravel surfaces.
9. Do not operate the machine without the entire grass
catcher, discharge guard (deflector), or other safety
devices in place.
10. Slow down before turning.
11. Never leave a running unit unattended. Always disen-
gage the PTO, set parking brake, stop engine, and
remove keys before dismounting.
12. Disengage blades (PTO) when not mowing. Shut off

Safety Rules and Information
SLOPE OPERATION
WARNING
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. If you can-
not back up the slope or if you feel uneasy on it, do not
operate on it.
Control of a walk-behind or ride-on machine sliding on a
slope will not be regained by the application of the brake.
The main reasons for loss of control are: insufficient tire
grip on the ground, speed too fast, inadequate braking, the
type of machine is unsuitable for its task, lack of awareness
of the ground conditions, incorrect hitching and load distrib-
ution.
Never operate on slopes greater than 17.6 percent
(10°) which is a rise of 3-1/2 feet (106 cm) vertically in
20 feet (607 cm) horizontally.
When operating on slopes use additional wheel
weights or counterweights. See your dealer/retailer
to determine which weights are available and
appropriate for your unit.
Select slow ground speed before driving onto slope.
In addition to front weights, use extra caution when
operating on slopes with rear-mounted grass
catchers.
Mow UP and DOWN the slope, never across the
face, use caution when changing directions and DO
NOT START OR STOP ON SLOPE.
1. Mow up and down slopes, not across.
2. Watch for holes, ruts, or bumps. Uneven terrain could
overturn the unit. Tall grass can hide obstacles.
3. Choose a slow speed so that you will not have to
stop or change speeds while on the slope.
4. Do not mow on wet grass. Tires may loose traction.
5. Always keep unit in gear especially when traveling
down slopes. Do not shift to neutral and coast down-
hill.
CHILDREN
Tragic accidents can occur if the operator is not alert to the
presence of children. Children are often attracted to the unit
and the mowing activity. Never assume that children will
remain where you last saw them.
6. Avoid starting, stopping, or turning on a slope. If tires
lose traction, disengage the blade(s) and proceed
slowly straight down the slope.
1. Keep children out of the mowing area and under the
watchful care of another responsible adult.
2. Be alert and turn unit off if children enter the area.
3. Before and during reverse operation, look behind and
down for small children.
4. Never carry children, even with the blade(s) off. They
may fall off and be seriously injured or interfere with
safe unit operation. 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.
7. Keep all movement on slopes slow and gradual. Do
not make sudden changes in speed or direction,
which could cause the machine to rollover.
8. Use extra care while operating machines with grass
catchers or other attachments; they can affect the
stability of the unit. Do not use on steeps slopes.
9. Do not try to stabilize the machine by putting your
foot on the ground (ride-on units).
10. Do not mow near drop-offs, ditches, or embank-
ments. The mower could suddenly turn over if a
wheel is over the edge of a cliff or ditch, or if an edge
caves in.
11. Do not use grass catchers on steep slopes.
12. Do not mow slopes you cannot back up them.
13. See your authorized dealer/retailer for recommenda-
tions of wheel weights or counterweights to improve
stability.
14. Remove obstacles such as rocks, tree limbs, etc.
15. Use slow speed. Tires may lose traction on slopes
even through the brakes are functioning properly.
16. Do not turn on slopes unless necessary, and then,
turn slowly and gradually downhill, if possible.
5. Never allow children to operate the unit.
6. Use extra care when approaching blind corners,
shrubs, trees, or other objects that may obscure
vision.
EMISSIONS
1. Engine exhaust from this product contains chemicals
known, in certain quantities, to cause cancer, birth
defects, or other reproductive harm.
2. Look for the relevant Emissions Durability Period and
Air Index information on the engine emissions label.
TOWED EQUIPMENT (RIDE-ON UNITS)
1. Tow only with a machine that has a hitch designed
for towing. Do not attach towed equipment except at
the hitch point.
IGNITION SYSTEM
1. This spark ignition system complies with Canadian
ICES-002.
2. Follow the manufacturer’s recommendations for
weight limit for towed equipment and towing on
slopes.
3. Never allow children or others in or on towed equip-
ment.
4. On slopes, the weight of the towed equipment may
cause loss of traction and loss of control.
5. Travel slowly and allow extra distance to stop.
6. Do not shift to neutral and coast down hill.

if the unit vibrates abnormally. After striking an
object, inspect the machine for damage and make
repairs before restarting and operating the equip-
ment.
11. Use extra care in handling gasoline and other fuels.
They are flammable and vapors are explosive.
12. If fuel is spilled, do not attempt to start the engine but
move the machine away from the area of spillage and
avoid creating any source of ignition until fuel vapors
have dissipated.
23. Never place hands near the moving parts, such as a
hydro pump cooling fan, when the tractor is running.
(Hydro pump cooling fans are typically located on top
of the transaxle).
13. Replace all fuel tank caps and fuel container caps
securely.
24. Units with hydraulic pumps, hoses, or motors: WARN-
ING: Hydraulic fluid escaping under pressure may
have sufficient force to penetrate skin and cause seri-
ous injury. If foreign fluid is injected into the skin it
must be surgically removed within a few hours by a
doctor familiar with this form of injury or gangrene
may result. Keep body and hands away from pin
holes or nozzles that eject hydraulic fluid under high
pressure. Use paper or cardboard, and not hands, to
search for leaks. Make sure all hydraulic fluid con-
nections are tight and all hydraulic hoses and lines
are in good condition before applying pressure to the
system. If leaks occur, have the unit serviced imme-
diately by your authorized dealer.
Service & Maintenance

Features & Controls
Attachment Lift Control Lever
When using the mower deck, lift the deck off the ground
while transporting to and from the job site. DO NOT cut
with the mower in the raised, transport position.
Ground Speed Pedals
The tractor’s forward ground speed is controlled by the
forward ground speed control pedal. The tractor’s
reverse ground speed is controlled by the reverse
ground speed control pedal. Note that the further down
the pedal is depressed, the faster the tractor will travel.
The attachment lift control lever raises and lowers
attachments that utilize the tractor’s hydraulic lift cylinder.
This lever also controls attachments that use the tractor’s
auxiliary hydraulics via the quick couplers on the front left
and right sides of the frame.
Parking Brake
The parking brake knob is used to lock the parking brake
when the tractor is stopped. Fully depressing the brake
pedal and pulling the knob out engages the parking
brake. Refer to page 10 for a full explanation of parking
brake functions.
When using a mower deck (Front / Rear Hydraulic selec-
tor switch must be in REAR position), pulling the lever
back raises the attachment lift. Pushing the lever for-
ward to the first detent lowers the attachment lift.
Pushing the lever forward to the second detent locks the
control in “float” position, allowing the lift mechanism to
float up and down. Float is the recommended position
when mowing.
Steering Tilt Adjust (Select Models)
Use the tilt knob located on the bellows to release the
pivot mechanism and pivot the wheel to the desired posi-
tion. Release the tilt knob to lock in position.
For a complete explanation on this control, see
HYDRAULIC SYSTEM FUNCTIONS.
Seat Adjustment Lever
Cutting Height Adjustment
The seat can be adjusted forward and back. Move the
lever, position the seat as desired, and release the lever
to lock the seat into position.
The cutting height adjustment switch controls the mower
cutting height. This same switch also controls the spout
rotator motor when a snowthrower is installed. The
arrows on the switch correspond to the direction of
adjustment (UP arrow raises cutting height, RIGHT arrow
rotates the spout right, etc). The mower cutting height is
infinitely adjustable between 1” to 4-13/32” (2,5 cm-11,2
cm). When the adjustment indicator has reached the
end of its travel, release the switch; holding the switch
down will damage the motor.
Cruise Control
The cruise control is used to lock the ground speed con-
trol in forward. Move the lever forward until the desired
ground speed is reached. To disengage the cruise con-
trol move the lever back. In the event you need to stop
quickly, depressing the brake pedal will also return the
cruise control to neutral.
Ignition Switch
The ignition switch starts and stops the engine, it has
three positions:
2WD
4WD
2-Wheel / 4-Wheel Drive Selector
(Select Models)
OFF
Stops the engine and shuts off the
electrical system.
The 2-wheel / 4-wheel drive selector disengages the
front wheels in the 2-wheel drive position and drives all
four wheels in 4-wheel drive position. Engage / disen-
gage the 4-wheel drive control only when stopped or at
slow speeds.
RUN
Allows the engine to run and powers the
electrical system. Activates the glow
plugs on diesel models
Transmission Release Valve Lever
START
Cranks the engine for starting.
The transmission release valve lever deactivates the
transmission so that the tractor can be pushed by hand.
See PUSHING THE TRACTOR BY HAND for opera-
tional information.
NOTE: Never leave the ignition switch in the RUN posi-
tion with the engine stopped–this drains the battery.
Brake Pedal
Depressing the brake pedal applies the tractor brake.
Depressing the brake pedal will also return the cruise
control lever to neutral.

Features & Controls
Differential Lock Pedal
Depressing this pedal locks the transmission differential,
locking both rear wheels into “drive”.
Transmission Oil Level Check Plug
Transmission oil check plug/dipstick is used to check
transmission oil level and to add oil to the transmission.
See TRANSMISSION MAINTENANCE for oil level check
and fill procedures.
Use this feature if the tractor is stuck because one wheel
is slipping. Engage the differential lock at slow
ground speeds only.
Mid / Rear PTO Selector
The mid / rear PTO selector lever selects which PTO or
combination of PTOs is activated by the PTO switch.
The selector has three positions (from front to back:)
mid PTO active only, mid and rear PTO active, rear PTO
active only. Disengage the PTO switch before altering
this control’s setting.
PTO Switch
The PTO (Power Take-Off) switch, in conjunction with
the mid / rear PTO selector, engages and disengages
attachments connected to the tractor’s mid or rear PTO
shafts. To engage the PTO, pull UP on the switch. Push
DOWN to disengage. Be sure to check the position of
the mid / rear PTO selector lever before engaging the
PTO. DO NOT engage a PTO that is not connected to
an attachment as the rotating shaft is a safety hazard.
Note that the operator must be seated firmly in the trac-
tor seat for the PTO to function.
Front / Rear Hydraulics Selector
The front / rear hydraulics selector switches which
hydraulic circuit is controlled by the forward and back-
ward movement of the attachment lift lever.
When the switch is in the forward position, the attach-
ment lift control lever affects attachments connected to
the two front left quick couplers. When the switch is in
the rear position the attachment lift control affects the
tractor’s hydraulic cylinder.
Reverse Mowing Option (RMO)
The Reverse Mowing Option allows for mowing (or use
of other PTO driven attachments) while traveling in
reverse. If you choose to mow or operate another
attachment in reverse, turn the RMO key after the PTO is
engaged. The L.E.D. light will illuminate, and the opera-
tor can then mow in reverse. Each time the PTO is dis-
engaged the RMO needs to be reactivated if desired.

Automatic Controlled Traction
What is Automatic Controlled Traction?
B
C
A
Automatic Controlled Traction (ACT) is an exclusive fea-
ture of our transmissions that provides improved traction.
ACT applies a preset amount of torque to both rear
wheels even if one starts slipping (a transmission without
ACT will lose traction completely if one rear wheel starts
slipping). This preset torque is just enough to provide
additional traction, and still allow the wheels to turn at dif-
ferent speeds in a tight turn without damaging the lawn.
Figure 2. Engaging the Parking Brake
A. Ground Speed Pedals
B. Brake Pedal
C. Parking Brake Knob
be exceeded, and one of the rear wheels may slip (for
instance if trying to turn up a hill while accelerating).
This is normal. If you start to lose traction, do not speed
up. Instead, slow to a stop, straighten the steering
wheel, and slowly accelerate. Stopping the tractor
allows the transmission to regain more traction.
What to Expect from Your ACT Tractor
For the most part, while using your tractor you will not
notice ACT working, and you will simply become accus-
tomed to increased traction an ACT transmission pro-
vides.
Under certain circumstances the ACT system limit can

Hydraulic System Functions
General
All of the inboard and auxiliary hydraulics are controlled
by the attachment lift control lever. The attachment lift
control lever raises and lowers attachments that utilize
the tractor’s hydraulic lift cylinder. This lever also con-
trols attachments that use the tractor’s auxiliary
hydraulics via the quick couplers on the front left and
right sides of the frame.
The rate of hydraulic fluid flow and pressure that are
available when using the auxiliary hydraulic quick cou-
plers is listed in the chart in Figure 5.
Figure 6. Inboard Hydraulics
The lever has five positions: left, right, back, forward (first
detent) and float (pushed forward to second detent).
A. Lift
B. Lower
Using Inboard Hydraulics
The inboard hydraulics control the tractor’s belly attach-
ment lift (mower deck) and three point hitch lift (if
equipped). The front / rear hydraulic selector switch
must be in the REAR position.
6). Pushing the lever forward to the first detent lowers
the attachment lift (B, Figure 6). Pushing the lever for-
ward to the second detent locks the control in “float”
position, allowing the lift mechanism to float up and
down.
Pulling the lever back raises the attachment lift (A, Figure

Using Auxiliary Hydraulics
The attachment lift control is also used to control attach-
ments that use the tractor’s auxiliary hydraulic couplers
located on the right and left front frame rails. The left set
of quick couplers is activated when the front / rear
hydraulic switch is turned to the FRONT position (this
disables the inboard hydraulic cylinder).
Moving the control lever to the left (A, Figure 7) angles
the attachment left. Moving the lever right (B, Figure 7)
angles the attachment right.
Pulling the lever back raises the attachment lift (A, Figure
8). Pushing the lever forward to the first detent lowers
the attachment lift (B, Figure 8). Pushing the lever for-
ward to the second detent locks the control in “float”
position, allowing the lift mechanism to float up and
down.

Locking The Hitch
The 3-point hitch can be locked in the raised position.
When a rear attachment is locked in the raised position,
the tractor’s on-board hydraulic cylinder can be used to
lift mid mounted attachments without having to remove
the rear attachment. For example, if a tractor equipped
with a tiller is to be used for mowing, the tiller can be
locked in the raised position allowing the mower to be
installed and used.

Operating the Tractor
540 Attachment Recommendations
START-UP AND STOPPING LOADS
GENERAL
This PTO can be used with direct drive attachments that
have small start-up and stopping loads like tillers or
mower decks.
This rear PTO was designed and tested with the 540
RPM rear tiller sold by Simplicity Manufacturing. There
are a wide variety of other 540 attachments available
from numerous manufacturers. It is impossible for us to
test every one of them. There are a few basic, common-
sense criteria that can be used to determine whether
these attachments are suitable for use with your tractor.
DO NOT use this PTO box with attachments that require
a large amount of torque to start: for example, attach-
ments such as direct drive chipper/shredders and large
silo blowers cannot be used because their starting and
stopping loads may damage the PTO clutch.
In general, any attachment that:
• stalls the engine,
Large attachments that have their own clutching mecha-
nism to lessen the load on the PTO box during starting
and stopping may be used provided they do not exceed
the 18 horsepower limit.
• requires the clutch to be toggled on and off while
starting, or
• takes longer than 3 seconds to reach operating
speed is too large.
OVERLOAD PROTECTION
PTO BOX OUTPUT SPEED & HORSEPOWER OUTPUT
Any attachment used with this PTO box MUST have
shear pin(s), shear bolt(s), a slip clutch, or some other
device to prevent PTO box damage if the attachment
should jam.
This rear PTO box is designed to output a maximum of
18 horsepower at 540 RPM. Therefore it should only be
used to run 540 RPM attachments that require 18 HP or
less.
Using this PTO box to run attachments that require
more than 18 HP or an input shaft speed other than
540 could result in poor performance, shortened
equipment life, or equipment damage, and will void
the tractor warranty. Improper use can also create
an unsafe condition resulting in injury.

Operating the Tractor
Attaching a Trailer
The maximum weight of a towed trailer should be less
than 800 lbs (363 kg). Secure the trailer with an appro-
priately sized clevis pin (A, Figure 23) and clip (B).
A
Excessive towed loads can cause loss of traction and
loss of control on slopes. Reduce towed weight when
operating on slopes. The surface being driven on greatly
impacts traction and stability. Wet or slippery surfaces
can greatly reduce traction and the ability to stop or turn.
Carefully evaluate the surface conditions before operat-
ing the tractor and trailer, and never operate on slopes
greater than 10°. See SLOPE OPERATION and
TOWED EQUIPMENT in the safety section of this manu-
al for additional safety information.

WARNING
Never store the unit (with fuel) in an enclosed,
poorly ventilated structure. Fuel vapors can
travel to an ignition source (such as a furnace,
water heater, etc.) and cause an explosion.
Fuel vapor is also toxic to humans and animals.
Before you store your unit for the off-season, read the
Maintenance and Storage instructions in the Safety
Rules section, then perform the following steps:
12 Volt Power Outlet
• Disengage the PTO, set the parking brake, and
remove the key.
CAUTION
Avoid Injury. Safe operation requires your full
attention. Do not wear radio or music headphones
while operating machine.
• Perform engine maintenance and storage measures
listed in the engine owner’s manual. This includes
draining the fuel system, or adding stabilizer to the
fuel (do not store a fueled unit in an enclosed struc-
ture - see warning).
The 12-volt accessory outlet is located in the left side
pod. It can be used to power small electronic devices.
The accessory must be rated at 14 amps or less.
• Battery life will be increased if it is removed, put in a
cool, dry place and fully charged about once a month.
If the battery is left in the unit, disconnect the nega-
tive cable.
Note: Operating a 12-volt accessory, especially with the
engine at idle, may cause battery discharge. When not
using the accessory outlet it must be covered with the
rubber plug to prevent moisture from causing a short cir-
cuit. Entrance of water into outlet can cause a short cir-
cuit.
Before starting the unit after it has been stored:
• Check all fluid levels. Check all maintenance items.
• Perform all recommended checks and procedures
found in the engine owner’s manual.
• Allow the engine to warm up for several minutes
before use.

TROUBLESHOOTING
While normal care and regular maintenance will extend
the life of your equipment, prolonged or constant use
may eventually require that service be performed to
allow it to continue operating properly.

To avoid serious injury, perform maintenance on
the tractor or mower only when the engine is
stopped and the parking brake engaged.
Always remove the ignition key, disconnect the
spark plug wire and fasten it away from the plug
before beginning the maintenance, to prevent
accidental starting of the engine.
The troubleshooting guide below lists the most common
problems, their causes, and remedies.

Battery Charging
WARNING
Keep open flames and sparks away from the
battery; the gasses coming from it are highly
explosive. Ventilate the battery well during
charging.
A dead battery or one too weak to start the engine may
be the result of a defect in the charging system or other
electrical component. If there is any doubt about the
cause of the problem, see your dealer. If you need to
replace the battery, follow the steps under Cleaning the
Battery & Cables in the Regular Maintenance Section.
To charge the battery, follow the instructions provided by

* The power ratings for an individual engine model are initially developed by starting with SAE (Society of Automotive
Engineers) code J1940 (Small Engine Power & Torque Rating Procedure) (Revision 2002–05). Given both the wide
array of products on which our engines are placed, and the variety of environmental issues applicable to operating
the equipment, it may be that the engine you have purchased will not develop the rated horsepower when used in a
piece of power equipment (actual “on–site” power). This difference is due to a variety of factors including, but not lim-
ited to, the following: differences in altitude, temperature, barometric pressure, humidity, fuel, engine lubrication, max-
imum governed engine speed, individual engine to engine variability, design of the particular piece of power equip-
ment, the manner in which the engine is operated, engine run–in to reduce friction and clean out of combustion
chambers, adjustments to the valves and carburetor, and other factors. The power ratings may also be adjusted
based on comparisons to other similar engines utilized in similar applications, and will therefore not necessarily match
the values derived using the foregoing codes.
