2. Loosen jam nuts and rotate by-pass valves open 5 turns
to push. This allows hydraulic fluid to by-pass the
pump and the wheels to turn (Fig. 15).
Important
Rotate by-pass valve a maximum of 5 turns
so the valve does not come out of the body causing fluid
to run out.
To Operate the Machine
If the by–pass valve is opened to push the machine by
hand, adjustment is required for operation. Refer to
Adjusting By-pass Valve on page 32.
Note: The machine will not drive unless by-pass valves
are properly adjusted.

Transporting Machines
Use a heavy-duty trailer or truck to transport the machine.
Ensure that the trailer or truck has all necessary lighting
and marking as required by law. Please carefully read all
the safety instructions. Knowing this information could
help you, your family, pets or bystanders avoid injury.
To transport the machine:
•
Chock and block wheels.
•
Securely fasten the machine to the trailer or truck with
straps, chains, cable, or ropes.
•
Secure a trailer to towing vehicle with safety chains.
Side Discharge or Mulch Grass
This mower has a hinged grass deflector that disperses
clippings to the side and down toward the turf.
Danger
Without the grass deflector, discharge cover, or
complete grass catcher assembly mounted in
place, you and others are exposed to blade contact
and thrown debris. Contact with rotating mower
blade(s) and thrown debris will cause injury or
death.
•
Never remove the grass deflector from the
mower because the grass deflector routes
material down toward the turf. If the grass
deflector is ever damaged, replace it
immediately.
•
Never put your hands or feet under the mower.
•
Never try to clear discharge area or mower
blades unless you release the bail and the power
take off (PTO) is off. Rotate the ignition key to
“OFF.” Also remove the key and pull the wire
off the spark plug(s).
Adjusting Height-of-Cut
The height-of-cut can be adjusted from 1 to 4-1/2 in.
(25 to 115 mm) in 1/4 in. (6 mm) increments. Adjustment
is done by relocating four hairpin cotter pins in different
hole location and by adding or removing spacers.
Note: Rear height–of–cut pins need at least one spacer or
damage can occur to bushing if none are used.
1. To adjust, remove hairpin cotter from height-of-cut
post (Fig. 16).
2. Select hole in height-of-cut post corresponding to the
height-of-cut desired (Fig. 16).
3. Lift on side of deck and remove hairpin cotter
(Fig. 16).
4. Add or remove spacers if needed and then align holes
and insert hairpin cotter (Fig. 16).
Note: Spare height–of–cut spacers may be stored on posts
and retained by a hairpin cotter.
