GENERAL OPERATION
• Read, understand, and follow all instructions in the manual and on
the unit before starting.
• Only allow responsible adults, who are familiar with the instruc-
tions, to operate the unit (local regulations can restrict operator
age).
• Clear the area of objects such as rocks, toys, wire, etc., which
could be picked up and thrown by the blade(s).
• Be sure the area is clear of other people before mowing. Stop unit
if anyone enters the area.
• Never carry passengers.
• Do not mow in reverse unless absolutely necessary. Always look
down and behind before and while travelling in reverse.
• Be aware of the mower discharge direction and do not point it at
anyone. Do not operate the mower without either the entire grass
catcher or the deflector in place.
• Slow down before turning.
• Never leave a running unit unattended. Always disengage the
PTO, set parking brake, stop engine, and remove keys before dis-
mounting.
• Turn off the PTO switch to disengage the blades when not mowing.
• Stop engine before removing grass catcher or unclogging chute.
• Mow only in daylight or good artificial light.
• Do not operate the unit while under the influence of alcohol or
drugs.
• Watch for traffic when operating near or crossing roadways.
• Use extra care when loading or unloading the unit into a trailer or
truck.
• Data indicates that operators, age 60 years and above, are
involved in a large percentage of riding mower-related injuries.
These operators should evaluate their ability to operate the riding
mower safely enough to protect themselves and others from injury.
• Keep in mind the operator is responsible for accidents occurring to
other people or property.
• All drivers should seek and obtain professional and practical
instruction.
• Always wear substantial footwear and trousers. Never operate
when barefoot or wearing sandals.
• Before using, always visually check that the blades and blade hard-
ware are present, in-tact, and secure. Replace worn or damaged
parts.
• Never operate the machine with defective guards, or without safety
protective devises in place.
• Disengage attachments before: refuelling, removing an attachment,
making adjustments (unless the adjustment can be made from the
operator’s position).
• When the machine is parked, stored, or left unattended, lower the
cutting means unless a positive mechanical lock is used.
• Follow the manufacturer’s recommendation for wheel weights or
counterweights.
SLOPE OPERATION
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 operate
on it.
Control of a 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: insuffi-
cient tire grip on the ground, speed too fast, inadequate braking, the type
of machine is unsuitable for it’s task, lack of awareness of the ground con-
ditions, incorrect hitching and load distribution.
Read these safety rules and follow them closely. Failure to obey these rules could result in loss of control
of unit, severe personal injury or death to you, or bystanders, or damage to property or equipment.
This mowing deck is capable of amputating hands and feet and throwing objects.
The triangle in text signifies important cautions or warnings which must be followed.
Safety Rules & Information
WARNING
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 to
determine which weights are available and
appropriate for your unit.
Select slow ground speed before driving onto slope.
In addition to front and rear weights, use extra caution
when operating on slopes with rear-mounted grass
catcher.
Mow UP and DOWN the slope, never across the
face, use caution when changing directions and DO
NOT START OR STOP ON SLOPE.
Do
• See your authorized dealer for recommendations of wheel weights
or counterweights to improve stability.
• Mow up and down slopes, not across.
• Remove obstacles such as rocks, tree limbs, etc.
• Watch for holes, ruts, or bumps. Uneven terrain could overturn the
unit. Tall grass can hide obstacles.
• Use slow speed. Tires may lose traction on slopes even through
the brakes are functioning properly. Choose a low gear so that you
will not have to stop or shift while on the slope.
• Use extra care with grass catchers or other attachments. These
can change the stability of the unit.
• Keep all movement on the slopes slow and gradual. Do not make
sudden changes in speed or direction.
• Always keep unit in gear especially when traveling downhill. When
clutching, release clutch slowly.
Do Not
• Do not start or stop on a slope. If tires lose traction, disengage the
blade(s) and proceed slowly straight down the slope.
• Do not turn on slopes unless necessary, and then, turn slowly and
gradually downhill, 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.
• Do not mow on wet grass. Reduced traction could cause sliding.
• Do not try to stabilize the unit by putting your foot on the ground.
• Do not use grass catchers on steep slopes.
• Do not mow slopes you cannot back up.
• Do not shift to neutral and coast down hill.

Safety Rules & Information
Slope Operation Continued
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.
• Keep children out of the mowing area and under the watchful care
of another responsible adult.
• Be alert and turn unit off if children enter the area.
• Before and during reverse operation, look behind and down for
small children.
• Never carry children. They may fall off and be seriously injured or
interfere with safe unit operation.
• Never allow children to operate the unit.
• Use extra care when approaching blind corners, shrubs, trees, or
other objects that may obscure vision.
TOWED EQUIPMENT
• Never allow children or others in or on towed equipment.
• Tow only with a machine that has a hitch designed for towing. Do
not attach towed equipment except at the hitch point.
• Follow the manufacturer’s recommendations for weight limit for
towed equipment and towing on slopes.
• On slopes, the weight of the towed equipment may cause loss of
traction and loss of control.
• Travel slowly and allow extra distance to stop.
• Do not shift to neutral and coast down hill.
TRANSPORTING AND STORAGE
• Always observe safe refueling and fuel handling practices when
refueling the tractor after transportation or storage.
• Always follow the engine manual instructions for storage prepara-
tions before storing the tractor for both short and long term periods.
• Always follow the engine manual instructions for proper start-up
procedures when returning the unit to service.
• Never store the unit or fuel container inside where there is an open
flame or pilot light, such as in a water heater. Allow unit to cool
before storing.

vice and repair requirements.
• Never attempt to make major repairs on this unit unless you have
been properly trained. Improper service procedures can result in
hazardous operation, equipment damage and voiding of manufac-
turer’s warranty.
• On multiple blade mowers, take care as rotating one blade can
cause other blades to rotate.
• Do not change engine governor settings or over-speed the engine.
Operating the engine at excessive speed can increase the hazard
of personal injury.
• Disengage drive attachments, stop the engine, remove the key,
and disconnect the spark plug wire(s) before: clearing attachment
blockages and chutes, performing service work, striking an object,
or if the unit vibrates abnormally. After striking an object, inspect

Features
& Controls
Figure 1. Tractor & Mower Controls
Throttle / Choke Control
The throttle controls engine speed. Move the throttle up
to increase engine speed and down to decrease engine
speed. Always operate at FULL throttle. Note: Moving
the throttle control fully forward closes the choke.
A
warm engine may not require choking.
Mower Cutting Height Lever
The cutting height adjustment lever controls the mower
cutting height.
Set the mower deck in the highest cutting
position when transporting to and from the mowing site.
Parking Brake Control Knob
Engages parking brake. Depress clutch/brake pedal fully
and pull up knob to engage parking brake. To disengage
brake, depress pedal and push knob down.
Fuel Tank
See “Checking/Adding Fuel” in the Maintenance Section.
PTO Lever
The PTO (Power Take-Off) lever engages and disengages
attachments that use the PTO. To engage the PTO, move
the lever forward. To disengage the PTO, move the lever
all the way back. You will feel the lever lock into both the
engaged and disengaged positions.
Note that the operator must be seated firmly in the
tractor seat for the PTO to function. Also note that the
tractor will not start unless the lever is in the disengaged
position.
Clutch / Brake Pedal
Depressing the clutch / brake pedal disengages the drive
clutch and applies the tractor brake.
CONTROL FUNCTIONS
The information below briefly describes the function of individual controls. Starting, stopping, driving, and mowing
require the combined use of several controls applied in specific sequences. To learn what combination and sequence
of controls to use for various tasks see the OPERATION section.
Please take a moment and familiarize
yourself with the name, location, and
function of these controls so that you will
better understand the safety and operating
instructions provided in this manual.

SAFETY INTERLOCK
SYSTEM TESTS
This unit is equipped with safety interlock switches
and other safety devices. These safety systems are
present for your safety: do not attempt to bypass
safety switches, and never tamper with safety
devices. Check their operation regularly.
Operational SAFETY Checks
Your unit is equipped with a seat switch safety sys-
tem. Check the seat switch operation every fall and
spring with the following tests.
Test 1 — Engine should NOT crank if:
• PTO lever is ENGAGED, OR
• Brake pedal is NOT fully depressed (parking
brake OFF), OR
• Ground speed lever is out of NEUTRAL position.
Test 2 — Engine SHOULD crank if:
• PTO lever is DISENGAGED, AND
• Brake pedal is fully depressed
(parking brake ON), AND
• Ground speed lever is in NEUTRAL position.
Test 3 — Engine should SHUT OFF if:
• Operator rises off seat with PTO engaged, OR
• Operator rises off seat with brake pedal NOT
fully depressed (parking brake OFF).
Test 4 — Blade Brake Check
Mower blades and mower drive belt should come to
a complete stop within five seconds after PTO is
turned OFF (or operator rises off seat). If mower
drive belt does not stop within five seconds, readjust
the PTO clutch as described in the ADJUSTMENTS
section or see your dealer.
NOTE: Once the engine has stopped, the PTO must
be turned off after the operator returns to the seat in
order to start the engine.
WARNING
If the unit does not pass a safety test, do not
operate it. See your authorized dealer. Under
no circumstance should you attempt to defeat
the purpose of the safety interlock system.
Ground Speed Control Lever
The tractor’s forward & reverse ground speed is con-
trolled by the ground speed control lever.
GEAR MODELS — On models with Gear transmissions,
ground speed is selected from one of 5 speeds.
To change gear positions, first fully depress the
clutch/brake pedal, move the ground speed control
lever to the appropriate gear position, then release
the clutch/brake pedal to begin tractor movement.
Note: On Gear Models, shift gears only with tractor
stopped and clutch/brake pedal fully depressed.
HYDRO MODELS — On models with Hydrostatic
transmissions, ground speed is selected from a continu-
ous range.
Moving the lever forward in the F range increases
FORWARD tractor motion, and moving the lever
back in the R range increases REVERSE tractor
motion. The further the lever is moved in either
range, the faster the tractor will travel in that direc-
tion.
Note: Depressing the clutch/brake pedal is NOT
necessary when changing speeds.
Placing the lever
in the N position puts the transmission in NEUTRAL,
and ceases tractor motion. (Apply & set the Parking
Brake before leaving the operator’s position).
Always mow with the engine speed at full throttle.
Note: If the terrain is rough, hilly, or sloping, use a slower
forward speed or gear. If the grass is wet or over three
inches (76mm) high, use full engine speed with a low for-
ward speed or gear 1 so the mower will have enough
power to cut the grass.
Ignition Switch
The ignition switch starts and stops the engine, it has
three positions:
OFF Stops the engine and shuts off the electrical
system.
RUN Allows the engine to run and powers the
electrical system.
START Cranks the engine for starting.
NOTE: Never leave the ignition switch in the RUN posi-

reach all controls from operator’s position.
• Fill the gasoline tank with fresh gasoline. Refer to
engine manual for gasoline recommendations.
• Make certain rear counterweights are installed if you
will be operating the unit on sloping ground.
WARNING
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 to
determine which weights are available and
appropriate for your unit.
Select slow ground speed before driving onto slope.
In addition to front and rear weights, use extra caution
when operating on slopes with rear-mounted grass
catcher.

Operating the Tractor
WARNING
Never store the unit, with gasoline in engine or
fuel tank, in a heated shelter or in enclosed,
poorly ventilated enclosures. Gasoline fumes may
reach an open flame, spark or pilot light (such as
a furnace, water heater, clothes dryer, etc.) and
cause an explosion.
Handle gasoline carefully. It is highly flammable
and careless use could result in serious fire
damage to your person or property.
Drain fuel into an approved container outdoors
away from open flame or sparks.
STORAGE
Temporary Storage (30 Days Or Less)
Remember, the fuel tank will still contain some gasoline, so
never store the unit indoors or in any other area where fuel
vapor could travel to any ignition source. Fuel vapor is also
toxic if inhaled, so never store the unit in any structure used
for human or animal habitation.
Here is a checklist of things to do when storing your unit
temporarily or in between uses:
• Keep the unit in an area where children will not come
into contact with it. If there’s any chance of unauthorized
use, remove the keys and disconnect the spark plug
wires.
• If the unit can’t be stored on a reasonably level surface,
chock the wheels.
• Clean all grass and dirt from the mower.
NOTE: If storing your tractor between winter snow removal
jobs in a cold area, we suggest that you fill the fuel tank at
the completion of each job to prevent water condensation in
the fuel tank. Wait for engine to cool before filling tank.
Long Term Storage (Longer Than 30 Days)
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:
1. Drain crankcase oil and refill with a grade of oil that will
be required when unit is used again.
2. Prepare the mower deck for storage as follows:
a. Remove mower deck from the unit.
b. Clean underside of mower deck.
c. Coat all bare metal surfaces with paint or light coat of
oil to prevent rusting.
3. Clean external surfaces and engine.
4. Prepare engine for storage. See engine owner’s
manual.
5. Clean any dirt or grass from cylinder head cooling fins,
engine housing and air cleaner element.
6. Cover air cleaner and exhaust outlet tightly with plastic
or other waterproof material to keep out moisture, dirt
and insects.
7. Completely grease and oil unit as outlined in the
Regular Maintenance section.
8. Clean up unit and apply paint or rust preventative to any
areas where paint is chipped or damaged.
9. Be sure the battery is filled to the proper level with water
and is fully charged. Battery life will be increased if it is
removed, put in a cool, dry place and fully charged
about once a month. If battery is left in unit, disconnect
the negative cable.
10. Drain fuel system completely or add a gasoline stabilizer
to the fuel system. If you have chosen to use a fuel sta-
bilizer and have not drained the fuel system, follow all
safety instructions and storage precautions in this man-
ual to prevent the possibility of fire from the ignition of
gasoline fumes. Remember, gasoline fumes can travel
to distant sources of ignition and ignite, causing risk of
explosion and fire.
NOTE: Gasoline, if permitted to stand unused for extended
periods (30 days or more), may develop gummy deposits
which can adversely affect the engine carburetor and cause
engine malfunction. To avoid this condition, add a gasoline
stabilizer to the fuel tank and run the engine a few minutes,
or drain all fuel from the unit before placing it in storage.
STARTING AFTER
LONG TERM STORAGE
Before starting the unit after it has been stored for a long
period of time, perform the following steps.
1. Remove any blocks from under the unit.
2. Install the battery if it was removed.
3. Unplug the exhaust outlet and air cleaner.
4. Fill the fuel tank with fresh gasoline. See engine
manual for recommendations.
5. See engine owner’s manual and follow all instructions
for preparing engine after storage.
6. Check crankcase oil level and add proper oil if
necessary. If any condensation has developed during
storage, drain crankcase oil and refill.
7. Inflate tires to proper pressure. Check fluid levels.
8. Start the engine and let it run slowly. DO NOT run at
high speed immediately after starting. Be sure to run
engine only outdoors or in well ventilated area.
