Tracking Adjustment
-IMPORTANT-
Before proceeding with this adjustment, be sure that
the tire pressure is correct, that the caster wheels
turn freely, and that the transmission drive belt
tension spring is not broken.
The mower tracking should be adjusted if the machine does
not travel in a straight line during forward travel.
Preform the neutral adjustment before proceeding with the
tracking adjustment.

on the right control rod and turn the rod slightly
clockwise, tighten the jam nuts and retest.
2. If the machine pulls to the left, loosen the jam nuts on
the left control rod and turn the rod slightly clockwise,
tighten the jam nuts and retest.
