operating the mower with the ROPS in the raised and locked position. Always keep seat belt snugly adjusted. DO NOT
use seat belts with the ROPS folded. See Section 4.12.
If the mower is overturning and the ROPS in the raised and locked position, hold onto the steering wheel. Do not attempt
to jump out or leave the seat.
CAUTION
To prevent injury, always wear safety glasses, leather work shoes or boots, a hard hat, and ear protection.
1. Under no circumstances should the engine be started
without the operator seated on the mower.
2. Do not operate mower or attachments with loose,
damaged, or missing components. Whenever possible
mow when grass is dry.
3. First mow in a test area to become thoroughly familiar
with the operation of the mower and control levers.
4. Study the area to determine the best and safest
operating procedure. Consider the height of the grass,
type of terrain, and condition of the surface. Each
condition will require certain adjustments or
precautions.
5. Never direct discharge of material toward bystanders,
nor allow anyone near the machine while in operation.
The owner/operator is responsible for injuries inflicted
to bystanders and/or damage to their property.
CAUTION
Before mowing, pick up all debris such as rocks, toys,
and wire which can be thrown by the machine. Enter a
new area cautiously. Always operate at speeds that
allow you to have complete control of the mower.
8. Disengage the drive motors and raise the decks when
crossing paths or roadways. Look out for traffic.
9. Stop and inspect the equipment for damage
immediately after striking an obstruction or if the
machine begins to vibrate abnormally. Have the

4.8 HILLSIDE OPERATION _____________________________________________________
WARNING
To minimize the possibility of overturning, the safest
method for operating on hills and terraces is to travel up
and down the face of the slope (vertically), not across the
face (horizontally). Avoid unnecessary turns, travel at
reduced speeds, stay alert for hidden hazards, and drop
offs.

14°
Maximum
The mower has been designed for good traction and
stability under normal mowing conditions; however, use
caution when operating on slopes, especially over rough
terrain, or when the grass is wet. Wet grass reduces traction
and steering control.

Figure 4B
1. Always mow with the engine at full throttle but reduce
forward speed for safe operation.
2. If the mower tends to slide or the tires begin to “mark”
the turf, angle mower into a less steep grade until
traction is regained or tire marking stops.
3. If mower continues to slide or mark the turf, the grade is
too steep for safe operation. Do not make another
attempt to climb, back down slowly.
4. When descending a steep slope, always lower
implements to the ground to reduce the risk of mower
overturning.
5. Correct tire pressure is essential for maximum traction.
Front - 16 to 20 psi (1.10 to 1.38 BAR)
Rear - 10 to 12 psi (0.69 to 0.83 BAR)
6. If additional traction is required, adjust the weight
transfer knob as described in the Parts and
Maintenance manual.

ROPS folded down on slopes, or near drop offs or water.
Only operate in these areas with the ROPS in the raised
and locked position.
traction pedal to the desired mowing speed.
a. For complete even cutting, overlap swaths by a few
inches.
b. When cutting tall grass, cut grass higher than
desired the first time so deck will clear unseen
obstructions and will not scalp if ground is rough.
c. Stop and raise the decks to the transport position
when crossing paths or roadways. Look out for traffic.
4. For better traction and handling, adjust weight transfer.
5. When operating in reverse and additional power is
required to climb out of a small depression, press and
hold the 2WD/4WD in the momentary 4WD Reverse

Seat belts must be worn whenever operating the mower
with the ROPS in the raised and locked position. Always
keep seat belt snugly adjusted. DO NOT use seat belts with
the ROPS folded down.
To fold ROPS, push top portion of ROPS towards front of
mower, remove pins, and fold ROPS towards rear of
mower. Secure ROPS in folded position with pins.
4.11 TOWING / TRAILERING _____________________________________________________
If the mower experiences problems and must be shut down
and removed from the area, it should be lo aded onto a trailer
for transport. If a trailer is not available, the unit can be towed
slowly short distances.
NOTE: Do not exceed 2 MPH (3.2 KPH) while towing.
Long distance towing is not recommended.
Use care when loading and unloading mower. Fasten
mower to trailer to prevent mower from rolling or shifting
during transport.
Before towing, open tow valve. The tow valve permits
moving the mower without starting the engine and prevents
possible damage to hydraulic components.
The tow valve (Z) is located on the drive pump beneath the
seat. Remove hardware and tilt seat towards left side
deck.To open valve, use a small wrench to turn the valve
counterclockwise 90°.
After towing, close tow valve completely and make certain

known to encourage rust and corrosion of met al p arts
resulting in premature deterioration or failure.
Damage of this nature is not cov ered by the factory
warranty.
b. Do not use high pressure spray.
c. Do not spray water directly at the instrument panel,
or any electrical components.
To prevent serious injury from hot, high pressure oil,
never use your hands to check for oil leaks, use paper or
cardboard.
Hydraulic fluid escaping under pressure can have
sufficient force to penetrate skin. If 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.
6. Inspect hydraulic hoses and tubes daily. Look for wet
hoses or oil spots and replace worn or damaged hoses
and tubes before operating the machine.
7. Check the engine oil and hydraulic oil at the start of
each day, before starting the engine. If the oil level is
low, remove the oil filler cap and add oil as required. Do
not overfill.
WARNING
d. Do not spray water into the cooling air intake or the
engine air intake.
NOTICE
Do not wash a hot or running engine. Use compressed
air to clean the engine and radiator fins.
3. Fill mower’s fuel tank at the end of each operating day
to within 1 in. (25 mm) below the filler neck.
Use clean, fresh #2 low or ultra-low sulfur diesel fuel.
Minimum Cetane Rating 45.
4. Handle fuel with care - it is highly flammable. Use an
approved container, the spout must fit inside the fuel
filler neck. Avoid using cans and funnels to transfer
fuel.
a. Never remove the fuel cap from the fuel tank, or add
fuel, when the engine is running or while the engine
is hot.
b. Do not smoke when handling fuel. Never fill or drain
the tank indoors.
c. Never overfill or allow the tank to become empty.
Do not spill fuel. Clean any spilled fuel immediately.
NOTICE
Care must be used at all times to avoid any
contamination of the hydraulic system. Follow
recommended maintenance practices and adhere to
scheduled intervals for hydraulic oil and filter changes.
Introduction of any type of contamination may result in
operating issues by causing valves to stick or leak
internally.
d. Never handle or store fuel containers near an open
flame or any device that may create sparks and
ignite the fuel or fuel vapors.
5. Store fuel according to local, state, or federal
ordinances and recommendations from your fuel
supplier.

5 QUALITY OF CUT
5.1 QUALITY OF CUT TROUBLESHOOTING _______________________________________
It is recommended that a “test cut” be performed to evaluate
the mower’s performance before beginning repairs.
Before performing a “test cut” to diagnose cut appearance
and mower performance, the following items should be
verified to ensure an accurate “test cut.”
An area should be available where “test cuts” can be made.
This area should provide known and consistent turf
conditions to allow accurate evaluation of the mower’s
performance.
1. Mowing (Ground) Speed
2. Blade Sharpness
3. Height-of-Cut (HOC)
Another “test cut” should be performed after the completion
of the repairs and/or adjustments to verify the mower’s
performance.
4. Decks Leveled
5. Blade Speed
6. Deck Rake not Set
5.2 WASHBOARDING__________________________________________________________
Washboarding is a cyclical pattern of varying cutting
heights, resulting in a wave-like cut appearance.
This condition is usually caused by the weight transfer not
set correctly.
Washboarding may also be caused by variations in the tu rf.
NOTE: Arrow indicates direction of travel.
Probable Cause Remedy
Decks have too much or too little weight on them. Adjust weight transfer valve to put more weight on decks.
