7.4.2 Wheel Spacing
The rear struts spacing are set at the factory and are designed to be adjustable to fit 18 to 44 inch
(45 to 112 cm) row spacing depending on the strut style equipped. Minimum row and crop damage
will be done if the tires are set to track in the center of the rows. Wheel spacing adjustments are
made by moving the spindle in or out utilizing different cross
- holes in the rear strut, or by reversing
the switch the tires which changes the offset in or out. Any wheel adjustments need to be made in
conjunction with the strut assembly as a whole from the machine center. Always space the tires first
as some spacing widths will end up offset from the center of the strut.
Set up wheel spacing as follows:
1. Measure the current wheel spacing and determine how far in or out the wheels need to be ad-
justed.
2. Jack up the corner of the frame to remove the load from the strut assembly and the tires.
3. Remove wheels and cross bolts as necessary
4. Use chart below to set desired wheel spacing.
5. Torque wheels to 125 foot pounds and re - torque after 1 hour of field use. Lug bolts should be
checked periodically and tightened if needed.

*Wheel setting results in a wheel spacing which center is 2" (5 cm) out from the center of the strut
which needs to be taken into account when setting strut spacing. In addition to maintain the proper
tire lug orientation if switching to 26" or 28" (66 or 71cm) spacing one tire from the left hand strut
needs to be switched with one tire from the right hand strut.
