3.15 Steering Control Arms

Check that both steering control arms are properly 
linked, free of debris, and operating freely. Swing the 
arms toward the operator seat, removing them from 
the neutral lock position. Slowly push both arms all the 
way forward, then all the way back. They should both 
move smoothly and easily, with no sticking, obstruc-
tion, or uneven tension. They should also “snap” back 
to neutral position, which is straight up and down and 
centered with the neutral position lock (notch in the 
frame).

Be sure to return and lock both control arms into neu-
tral position.

The control arms can be adjusted for operator comfort 
by repositioning the control arms on the control assem-
bly.

On those units so equipped, unit control may also be 
accomplished with foot pedals that are interconnected 
with the control arm.
