Safety Rules
Read these safety rules and follow them closely. Failure to obey these rules could result in loss of control of vehicle, severe personal Injury
or death to you, yourself or bystanders, or damage to property or equipment. This cutting machine Is capable of amputating hands and
feet and throwing objects. The triangle ^ in text signifies Important cautions or warnings which must be followed.
IMPORTANT - Safe operation practices for riding mowers.
I. G eneral operation
1. Read, understand, and follow all instructions in the manual and on
the machine before starting.
2. Only allow responsible adults, who are familiar with the instruc¬
tions, to operate the machine.
3. Clearthe area of objects such as rocks, toys, wire, etc., which could
be picked up and thrown by the blade.
4. Be sure the area is clear of other people before mowing. Stop
tractor if anyone enters the area.
5. Never carry passengers.
6. Do not mow in reverse unless absolutely necessary. Always look
down and behind before and while backing.
7. 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 guard in place.
6. Slow down before turning.
9. N ever leave a running tractor unattended. Always turn off blades,
set parking brake, stop engine, and remove keys before
dismounting.
10. Turn off blades when not mowing.
11. Stop engine before removing grass catcher or unclogging chute.
12. Mow only in daylight or good artificial light.
13. Do not operate the tractor while under the influence of alcohol or
drugs.
14. Watch for traffic when operating near or crossing roadways.
15. Use extra care when loading or unloading the tractor into a trailer
or truck.
II. 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 mow it.
DO
• Refer to page 14 for recommendations for 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
machine. Tall grass can hide obstacles.
• Use slow speed. 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 machine.
• Keep all movement on the slopes s/ow and gradual. Do not make
sudden changes in speed or direction.
• Avoid starting or stopping on a slope. If tires lose traction, disen¬
gage the blades and proceed slowly straight dovm the slope.
2

Safety Rules
DO NOT
• Do noMum on slopes unless necessary, and then, turn slowly and
gradually downhill, if possible.
• Do notmow near drop-offs, ditches, or embankments. The mower
could suddenly turn over if a wheel is over the edge of a diff or ditch,
or if an edge caves in.
• Do not mow on wet grass. Reduced traction couid cause siiding.
• Do not try to stabilize the machine by putting your foot on the
ground.
• Do not use grass catcher on steep slopes.
ill. Children
Tragic acddents can occur if the operator is not alert to the presence of
children. Children are often attracted to the machine and the mowing
adivity. Never assume that children will remain where you last saw them.
1. Keep children out of the mowing area and under the watchfiii care
of another responsibie adult.
2. Be alert and turn machine off if children enter the area.
3. Before and when backing, look behind and downfor small children.
4. Never carry children. They may fall off and be seriously injured or
interfere with safe machine operation.
5. Never allow children to operate the madiine.
6. Use extra care when approaching blind corners, shrubs, trees, or
other objects that may obscure vision.
IV. Service
1. U se extra care in handling gasoline and other fuels. They are
flammable and vapors are explosive.
a) Use only an approved container.
b) Never remove gas cap or add fuel wrth the engine running. Allow
engine to cool before refueling. Do not smoke.
c) Never refuel the machine indoors.
d) Never store the machine or fuel container inside where there is
an open flame, such as in a water heater.
2. Never run a machine inside a closed area.
3. Keep nuts and bolts, especially blade attachment bolts, tight and
keep equipment in good condition.
4. Never tamper with safety devices. Check their proper operation
regularly.
5. Keep machine free of grass, leaves, or other debris build-up. Clean
up oil or fuel spillage. Allow machine to cool before storing.
6. Stop and inspect the equipment if you strike an object. Repair, if
necessary, before restarting.
7. Never make adjustments or repairs with the engine running.
8. Grass catcher components are subject to wear, damage, and
deterioration, which could expose moving parts or allow objects to
be thrown. Frequently check components and replace with
manufacturer’s recommended parts, when necessary.
9. Mower blades are sharp and can cut. Wrap the blade(s) or wear
gloves, and use extra caution when servicing them.
10. C heck brake operation frequently. Adjust and service as required.
A WARNING
Never operate on slopes greater than 30 percent (16.7) which is
a rise of three feet in a travei distance of ten feet. When
operating on siopes that are greater than 15 percent (8.5) but
iess than 30 percent, use front counterweights and rear wheei
weights. In addition to front and rear weights, use extra caution
when operating on slopes with rear-mounted grass catcher.

Operation
SAFETY INTERLOCK SYSTEM
Your tractor is equipped with a seat switch safety system that
will automatically shut the engine off when the operator leaves
the seat with the PTO engaged or the transmission lever in
gear. The tractor engine will continue to run when the operator
leaves the seat if the PTO is disengaged and the transmission
is in neutral.
Check the seat switch (A, figure 9) every fall and spring with the
following three tests. Make sure the wiring harness (B) is
securely plugged into the switch.
Test 1 — Engine should NOT crank If:
A. Seat not occupied or;
B. Transmission lever out of neutral, or;
C. PTO switch engaged.
Test 2 — Engine should crank If:
A. Seat is occupied, and;
B. Transmission lever in neutral, and;
C. PTO disengaged.
Test 3 — Engine should shut off If:
A. Operator rises off seat with
transmission lever in gear, or:
B. Operator rises off seat with PTO engaged.

Operation
PUSHING THE TRACTOR BY HAND (Hydro Models)
To push the tractor by hand, the hydro release lever (A, figure
10) must be in the "PUSH" position. Rotate the lever upwards
and engage lever capscrew in wrapper hole. To drive tractor,
rotate lever downward, making sure that bottom of lever is
several inches away from plunger (B).
BEFORE OPERATING
1. Refer to Normal Care Chart and perform any needed care.
2. Clear the work area of any objects which may be caught in
or thrown by the attachment.
RECOMMENDED FUEL
Refer to your engine manual for specific fuel and oil
recommendations. Never use gasoline containing methanol,
gasoline containing more than 10% ethanol, gasoline additives
(except gas stabilizer for winter storage), premium gasoline, or
white gas because engine/fuel system damage could result.

Operation
STARTING THE ENGINE
1. Seat yourself on tractor seat in operating position. Set the
parking brake.
2. Set engine speed controi to CHOKE. A warm engine may
not require choking.
3. Lift the PTO lever as far as it wiii go to the rear to disengage
the attachment.
4. Set ground speed controi iever in NEUTRAL.
5. Insert the key into the ignition switch and turn it to START.
When engine starts, reiease the key.
6. Move the engine speed controi to SLOW. Warm up the
engine by running it for at ieast a minute before engaging
the PTO iever or driving the tractor.
SELECTING GROUND SPEED & ENGINE SPEED
On hydro models, ground speed is infinitely variable according
to how far the control lever is pushed forward or reverse. Run
engine at full throttle and use control lever to select ground
speed. On gear models, most mowing is done in third or fourth
gear with engine speed between 3/4 and full speed. If the
terrain is rough, hilly, or sloping, use first or second gear. If the
grass is wet or over three inches (76 mm) high, use full engine
speed (with low gear) so the mower will have enough power to
cut the grass. Shift gears only with tractor stopped and clutch-
brake pedal fully depressed.
^WARNING
Slope Operation
Never operate on slopes greater than 30 percent (16.7°)
which is a riseof three feet vertically in 10feet horizontally.
When operating on slopes that are greaterthan 15 percent
(8.5°) but less than 30 percent use rear wheel weights (see
your dealer). Select slow ground speed before driving
onto slope. Mow UP and DOWN the slope, never across
the face, use caution when changing directions and DO
NOT START OR STOP.
STARTING & STOPPING
1. Start the engine.
2. Set engine control for 1/3 to 1/2 speed. Select the gear best
suited for conditions.
3. Release the parking brake by depressing clutch-brake
pedal and unlatching pedal from the foot rest.
4. Make sure the path in desired direction of movement is
clear.
5. If you are ready to mow, engage the mower PTO with
moderately fast motion. Engaging PTO too slowly may
cause belt wear.
6. Slowly release the clutch-brake pedal to engage clutch and
start tractor into motion.
7. Adjust engine speed control to desired speed. Between 3/4
and full speed is recommended for mowing.
14

Operation
8. For a gradual stop on gear models, press the pedal down
only far enough to disengage the clutch (refer to figure 11).
For a more rapid stop, press pedal down farther to apply
the brake. See “Before Leaving Operator’s Position” (next
page). For a gradual stop on hydro models, move the
transmission controi iever into NEUTRAL position. For a
more rapid stop, depress the clutch-brake pedal. If you stop
by depressing the pedal, move control lever to NEUTRAL
before releasing pedal.
BEFORE LEAVING THE OPERATOR’S POSITION:
1. Stop tractor motion and engage parking brake.
2. Disengage the PTO and iower the attachment.
3. Set engine speed control to SLOW. Stopping a hot engine
too fast may cause engine damage. Let engine idle for
about a minute.
4. Turn key to OFF and remove it.
A WARNING
Before leaving the operator’s position for any reason,
engage the parking brake, disengage the PTO, stop the
engine and remove the key.
^WARNING
To reduce fire hazard, keep the engine, tractor and mower
free of grass, leaves and excess grease.
CLUTCH/BRAKE PEDAL OPERATION
Refer to figure 11. Depressing pedal from position Ato B
disengages transmission drive. Depressing pedal further from
position B to C wili also apply tractor brake. Parking brake is
applied at position C when pedal is latched over foot rest as
shown in figure 11.

Operation
MOWING PATTERN & TIPS
For the first use of the mower choose a smooth level area. Cut
long straight strips overlapping slightly.
The size and type of area to be mowed determine the best
mowing pattern to use. Obstructions such as trees, fences and
buildings must also be considered. Where possible, make one
or two passes in a clockwise direction around the outside of the
area to keep cut grass off fences and walks. The remainder of
the mower should be done in a counterclockwise direction so
the clippings are dispersed on the cut area.
Where possible, keep the left side of the mower toward trees,
posts, or other obstacles on the first pass around the obstacles
to keep hand trimming to a minimum.
On moderate size, frequently mowed lawns where grass is light
and dry, it is sometimes practical to mow in a clockwise
direction so clippings are thrown toward the center of the lawn
and concentrated for pickup and removal.
Most lawns should be mowed to keep the grass approximately
two to three inches (50 to 76 mm) high. Best results are
obtained by cutting often and not to short. To help keep a green
lawn, never mow more than one third off the height of the grass,
or a maximum of one inch (25 mm), in one mowing. For
extremely tall grass, set the cutting height at maximum for the
first pass, and then reset to the desired height and mow again.
On thick, or springy grass or soft ground, the mower rollers sink
into the ground giving too low a cut. Adjust the cutting height as
necessary. For best appearance, grass should be cut in the
afternoon or early evening (in daylight) where it is free of
external moisture.
Where possible, change patterns occasionally to eliminate
matting, graining or a corrugated appearance.

Normal Care_
DETERMINING OPERATING TIME
Determining operating time is easily accomplished if the tractor
is equipped with an optional hourmeter. If not. multiply the time
it takes to do one job by the number of times you’ve done the
job.
NORMAL CARE SCHEDULE
A schedule for normal care is provided in Table 1. If your tractor
is not equipped with an optional hourmeter, you will need to
keep a record of operating time.
RAISING HOOD & SEAT DECK
To raise the hood, grasp both sides of the hood (A, figure 12)
near the dash and pull outward. Pivot the hood up and forward.
To open the seat deck, pull down the latch (B) under the foot
rest and tilt seat deck back.
ADJUSTING THE SEAT
Raise the seat deck. While holding the seat, loosen the four
capscrews (C, figure 9) that secure seat to seat deck. Position
the seat as desired then tighten the capscrews.
Seat springs (D, figure 9) can be adjusted for operator comfort.
Move springs forward for lighter operator and toward the rear
for heavier operator.
