TWINSTICK STEERING
CONTROL ADJUSTMENT
8. 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.
9. 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” Allen 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.
10. 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 may
be 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.)
11. 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
or 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 needs 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”
allen 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.
