The primary reason the unit may not track straight is
incorrect or unbalanced tire air pressure.
1. First, check and adjust the tire pressure.

on jack stands, check the circumference of the tire.
If one tire is larger than the other, increase
pressure in the small tire and/or decrease pressure
in the larger tire.

handles. The roller bearing on the speed control
arm must be in the neutral position on the neutral
detent strap.
4. Adjust upper control arm linkage until the control
handles will enter the neutral switch slot and
activate the neutral switches.
5. Tighten locking nuts on the control linkage.
6. Disconnect linkage from the transmission, loosen
two cap screws in the speed control arm and
position pump weldment in the horizontal position
and tighten cap screws.
