8. STEERING CONTROL ADJUSTMENTS A.
To Adjust Neutral:
a. Remove the fender skirts from each
side of the machine.
b. Block up the unit so that the Drive
Wheels are off the ground.
c. Start the engine and run at a fast idle
with the Steering control levers in the
"out" position.
d. Loosen the locknuts tightened against
the rod end ball joints in the Upper
Linkage Assembly. (Note: One of these
is a left hand nut and will have to be
turned backwards.)
e. Adjust the Neutral Position by turning
the rod in the upper linkage until the
wheel stops turning.
f. Retighten the nuts on the Upper
Linkage Assembly and check to see that
the drive wheel is still not turning.
g. Repeat steps 1-6 for the other side.
h. Shut off engine before removing the
blocks.
B. To Adjust "IN" Position of the Steering
Controls:
a. Remove the 2 Front Bolts,
Lockwashers, and Washers which hold
the Fender Cap.
b. Pull the boot from the hole in the
fender cap, exposing the cast iron lever.
c. Using a 5/32° Alien Wrench, turn the
setscrew to adjust the stop.
d. Replace the Boot into the hole in the
Fender Cap.
c. Replace the 2 Front Bolts,
Lockwashers, and Washers.
C. To Align Handles:
Sit on the seat and push the control
levers full forward and full backward. If
the ends do not match the handles
maybe adjusted as follows:
a. Locate Setscrew stops in the Steering
Control Lever Base which stop the lever
in each direction. (Note: The one at the
rear is the stop for FWD and the one in
the front is the stop for REV.)
b.-Adjust setscrew stops so that handles
line-up together when shifted full forward
and full reverse. *'
D. Adjusting for Straight Forward
Tracking:
In a large open area, actuate the control
handles into the full forward position. If the
mower veers in either direction Left for
Right some adjustment is necessary. a. If
the mower veers to the right, then the
right hydrostat needs to be sped up. If the
mower veers to the left, then the left
hydrostat need to be sped up. b. Stop the
machine and shut off the engine.
c. Slightly loosen the bolt at the lower end
of the upper linkage assembly on the side
that is slower. Using a 1/8" alien wrench
turn the setscrew 1/4 turn in. It may take
several test drives to get the mower to
track straight forward. d. Once the
tracking is to the operators liking,
completely tighten the bolt on the control
linkage assembly that was loosened
earlier.
e'. Recheck to make sure neutral adjust
has not been effected, see procedure A.
