Adjusting the Tracking
If you push both motion-control levers forward the
same distance and the machine pulls to 1 side, adjust
the tracking as follows.
1.
Park the machine on a level surface, disengage
the PTO, 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.
Release the cushion from the rear of the
machine; refer to
Rear Access (page
Note:
For easier access, you can also remove
the fuel tank; refer to
(page
39).
4.
Rotate the left control rod in quarter-turn
increments until the machine tracks straight
(Figure
65).
Note:
If the machine pulls to the right, shorten
the control rod by rotating it to the right. If the
machine pulls to the left, lengthen the rod by
rotating it to the left.
Note:
Adjust only the left control rod to match
the left wheel speed to the right wheel speed.
Do not adjust the right wheel speed, as this
positions the right motion-control lever out of the
center for the control panel neutral-lock slot.
Important:
Do not rotate the control rod too
far, as this may cause the machine to creep
in neutral.
