4.9 MOWING _________________________________________________________________

To mow:

1.

Start the engine and lower the decks to the ground.

2.

Turn PTO switch to ON, depress front of desired deck
switch(es), shift mower to 4WD, and disengage
parking brake.

3.

Move throttle lever to FAST then slowly depress
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 traf-
fic.

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
position.

4.10 FOLDING ROPS ___________________________________________________________

A folding Roll Over Protection Structure (ROPS) is included
with this mower.

Study the area of operation to determine if folding the ROPS
is required. Be aware of overhead obstructions and turf
conditions. Only operate the mower with the ROPS folded
down when absolutely necessary.

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 loaded 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
seat is closed and secured.

WARNING

To prevent serious injuries, keep hands, feet, and
clothing away from cutting unit when the blades are
moving. 

NEVER

 use your hands to clean cutting units. Use a

brush to remove grass clippings from blades. Blades can
be sharp and could cause injuries. 

To clear obstructions from cutting unit, disengage PTO
switch, engage parking brake, stop engine, and remove
key from ignition switch then remove obstruction.

!

 

WARNING

There is no roll over protection with the ROPS
folded down. 

NEVER

 

operate the mower with the

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.
