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.

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.
