Safety Rules and Information
SLOPE OPERATION
Slopes are a major factor related to loss-of-control and tipover accidents, which can result in severe injury or death.
Operation on all slopes requires 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: 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 distribution.
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 downhill.
6. Avoid starting, stopping, or turning on a slope. If tires
lose traction, disengage the blade(s) and proceed
slowly straight down the slope.
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 attachment; they can affect the stability of the unit.
9. Do not try to stabilize the machine by putting your
foot on the ground.
10. 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.
11. Do not use grass catchers on steep slopes.
12. Do not mow slopes you cannot back up.
13. See your authorized dealer for recommendations 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.
TOWED EQUIPMENT
1. Tow only with a machine that has a hitch designed
for towing. Do not attach towed equipment except at
the hitch point.
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 equipment.
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.
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.

object. Repair, if necessary, before restarting.
7. Never make adjustments or repairs with the engine
running unless specified otherwise in the engine manufacturer’s manual.
8. Do not remove the fuel filter when the engine is hot
as spilled gasoline may ignite. Do not spread fuel line
clamps further than necessary. Ensure clamps grip
hoses firmly over the filter after installation.
9. Do not use gasoline containing METHANOL, gasohol
containing more than 10% ETHANOL, gasoline additives, or white gas because engine/fuel system damage could result.
10. If the fuel tank must be drained, it should be drained
outdoors.
11. Replace faulty silencers/mufflers.
12. 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.
13. Mower blades are sharp and can cut. Wrap the
blade(s) or wear gloves, and use extra caution when
servicing them.
14. Check brake operation frequently. Adjust and service
as required.
15. Use only factory authorized replacement parts when
making repairs.
16. Always comply with factory specifications on all settings and adjustments.
17. Only authorized service locations should be utilized
for major service and repair requirements.
18. 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 manufacturer’s
warranty.
19. On multiple blade mowers, take care as rotating one
blade can cause other blades to rotate.
20. Do not change engine governor settings or overspeed the engine. Operating the engine at excessive
speed can increase the hazard of personal injury.
21. 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 the machine for damage and make
repairs before restarting and operating the equipment.
22. 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).

4. With the parking brake engaged, measure the compressed spring length. The spring should be 2-1/2”
(6,4 cm) when compressed.
If the spring is not within this range, turn the adjustment nut (B, Figure 29) to compress or release the
spring.
If this adjustment does not correct a braking problem,
see your dealer.

Troubleshooting, Adjustment, & Service
BATTERY 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 battery charger manufacturer as well as all warnings
included in the safety rules sections of this book. Charge
the battery until fully charged (until the specific gravity of
the electrolyte is 1.250 or higher and the electrolyte temperature is at least 60° F). Do not charge at a rate higher than 10 amps.
WARNING
Keep open flames and sparks away from the
battery; the gasses coming from it are highly
explosive. Ventilate the battery well during
charging.
CATCHER-FULL ALARM
ADJUSTMENT
To adjust the “catcher full” alarm, slide the sensor plate
(A, Figure 30) forward or backward on the sensor rod. If
the chute is plugging, slide the plate backwards to
increase sensitivity. If the alarm is going on before the
hopper is full, slide the plate forwards to decrease sensitivity.
MOWER LIFT ADJUSTMENT
The mower lift rod (A, Figure 31) can be inserted into two
holes depending on the amount of mower lift desired.
The upper hole provides higher mower lift when the
attachment lift lever is placed in transport position. The
lower hole will not lift the mower as high in transport
position, but requires less lift effort.

Troubleshooting, Adjustment, & Service
PTO CLUTCH ADJUSTMENT
Check the PTO clutch adjustment after the initial 25 hour
break-in period and then after every 250 hours of operation. Also perform the following procedure if the clutch is
slipping or will not engage, or if a new clutch has been
installed.
1. Remove key from ignition switch and disconnect
spark plug wires to prevent the possibility of accidental starting while the PTO is being adjusted.
2. See Figure 32. Note the position of the 3 adjustment
windows (A) in the side of the brake plate and the
nylock adjustment nuts (B).
3. Insert a .012”-.015” (2,5-4mm) feeler gauge (C)
through each window, positioning the gauge between
the rotor face and the armature face as shown in
Figure 33.
4. Alternately tighten the adjustment nuts (B, Figure 32)
until the rotor face and armature face just contacts
the gauge.
5. Check the windows for an equal amount of tension
when the gauge is inserted and removed, and make
any necessary adjustments by tightening or loosening the adjustment nuts.
NOTE: The actual air gap between the rotor and armature may vary even after performing the adjustment procedure. This is due to dimensional variations on component parts, and is an acceptable condition.
6. Check the mower blade stopping time. The mower
blades and mower drive belt should come to a complete stop within five seconds after the electric PTO
switch is turned off.
7. Perform the BLADE BRAKE CHECK found in the
MAINTENANCE Section. Mower blades and mower
drive belt should come to a complete stop within five
seconds after electric PTO switch is turned off.

TRANSMISSION PURGING
Purge the transmission if the unit is excessively noisy or
lacks drive in forward or reverse.
1. Elevate the rear end of the tractor using a chain hoist
or floor jack. Support the rear of the unit using jackstands. Elevate the unit just high enough for the rear
wheels to clear the ground.
2. Activate the seat switch, depress the clutch / brake
pedal, and start the engine. After the engine has
started, set throttle to IDLE.
3. Release the brake pedal and fully depress the forward ground speed pedal.
4. While holding the forward ground speed pedal down,
engage and disengage the transmission release
valve lever (A, Figure 34) several times.
5. Fully depress the reverse ground speed pedal.
6. While holding the reverse ground speed pedal down,
engage and disengage the transmission release
valve lever (A) several times.
7. Engage the transmission release valve lever and
stroke the transmission from full forward to full
reverse several times.
8. Lower the tractor and test run for several minutes.

MOWER ADJUSTMENTS
Cutting Height Adjustment
The cutting height adjustment lever (A, Figure 35) controls the mower cutting height. Push the button to
release the lever. Move the lever back to raise the deck
and forward to lower it.
Leveling The Mower
If the cut is uneven, the mower may need leveling.
Unequal or improper tire pressure may also cause an
uneven cut. Make sure tire pressure is correct as specified in Checking Tire Pressure.
1. With the mower installed, place the tractor on a
smooth, level surface such as a concrete floor. Turn
the front wheels straight forward.
2. Check for bent blades and replace if necessary.
3. Disengage the PTO. Place the mower in mid-cut
position. Arrange one of the mower blades so that it
is pointing from side-to-side.
4. Measure the distance between the outside tips of
each blade and the ground. If there is more than 1/8”
(3mm) difference between the measurements on
each side, proceed to step 5. If the difference is 1/8”
(3mm) or less, proceed to step 6.
5. See Figure 36. Loosen the outside nut (A). Turn the
eccentric nut (B) to raise or lower left-hand side of
mower. When mower is level, hold the eccentric nut
while tightening the outside nut.
6. Arrange the blades so they face front-to-back.
7. Measure the distance from the ground to front tip and
rear tip of the left and right-hand blades.
Front tips should be 1/8”-1/4” higher. If not, proceed
with steps 8 - 10.
8. See Figure 37. To raise front of mower deck, loosen
front nut (A) and turn rear nut (B) against bracket (C).
9. To lower front of mower deck, loosen rear nut (B) and
bracket (C) will move backwards to lengthen rod.
10. Re-check measurement before tightening front nut
(A) against bracket.
