Adjust Steering Tie Rod
Refer to Figure 41
54. Adjust tie rod to these objectives:
• The rod is installed at the factory but tire
alignment needs to be checked and adjusted
once final field assembly is complete.
• Pivot both casters until the tires are close to full
trailing (straight running) orientation. All
measurements must be made with the tires in a
position to have the planter traveling straight
forward.
• Measure the distance from the center of one
tire to the center of the other tire both in front of
the tires as well as behind the tires.
• The measurements are to be equal. If the
measurement across the front of the tires is less
than the measurement across the back of the
tires then the tie rod needs to be lengthened. If
the measurement across the front is more than
the measurement across the back then the tie rod
needs to be shortened.
• Make the appropriate adjustment then re-center
the tires and take another set of dimensions.
• Repeat as necessary until the dimensions are
equal.
• Do NOT have any toe in or toe out.
• Tighten the lock nuts on the ends of the tie rod.
(Right side has right-hand thread and left side
has left-hand thread.)
