Adjusting the
Control-Handle Position
There are 2 height positions for the control
levers—high and low. Remove the bolts to adjust the
height for the operator.
1.
Park the machine on a level surface, disengage
the blade-control switch, and engage the parking
brake.
2.
Shut off the engine, remove the key, and wait
for all moving parts to stop before leaving the
operating position.
3.
Loosen the bolts and flange nuts installed in the
levers (
).
4.
Align the levers in the front-to-rear position by
bringing the levers together to the N
EUTRAL
position, and slide them until they are aligned,
then tighten the bolts (
).

Adjusting the
Motion-Control Linkage
Located on either side of the machine, below the seat,
are the pump-control linkages. Rotating the end nut
with a 1/2-inch deep socket wrench allows fine tuning
adjustments so that the machine does not move in
neutral. Any adjustments should be made for neutral
positioning only.
WARNING
The engine must be running and the drive
wheels turning so that you can perform the
adjustments. Contact with moving parts or
hot surfaces may cause personal injury.
Keep your fingers, hands, and clothing clear
of rotating components and hot surfaces.
1.
Park the machine on a level surface, disengage
the blade-control switch (PTO), move the
motion-control levers to the N
EUTRAL
-
LOCK
position, and engage the parking brake.
2.
Shut off the engine, remove the key, and wait
for all moving parts to stop before leaving the
operating position.
3.
Push the deck-lift pedal, remove the height-of-cut
pin, and lower the mower deck to the ground
4.
Raise the rear of the machine up and support it
with jack stands (or equivalent support) just high
enough to allow the drive wheels to turn freely.
