Axle Wheel Spacing Adjustment
Refer to Figure 52
Axle extension can be adjusted for differing row spac-
ings.
Do not change the fore/aft position of the axle mount, Moving
it forward may result in negative tongue weight even when
folded. Moving it aft increases positive tongue weight and
risks tire contact with boom.
1. Hitch the sprayer on level ground.
2. Measure the current wheel spacing (span) between
tread center-lines.
Note: Also measure the distance from the outer end of
each axle to the mount. Keep these equal, or the
sprayer will pull skewed.
3. Compute the difference between the current and
desired spans. Divide it by two. This is the amount to
extend or retract each axle.
4. Use a hoist or jacks at the left rear corner of the
mainframe to raise the sprayer until the tire on that
side (only) is slightly elevated off the ground.
Leave the other tire firmly on the ground to provide resistance
to lateral frame movement when adjusting an axle.
5. Loosen the bolts joining the upper and lower axle
mounts, starting with the bolts nearest the wheel
being adjusted. Loosen only enough bolts to allow
movement of the axle to be adjusted.
6. Slide the axle in or out to the new setting.
Do not adjust the wheel spacing wider than:
120in (305cm) on North American models, or
290cm (114in) on export models
at tire tread center lines. To do so may cause a falling axle
hazard while the sprayer is in service.
7. Secure the four bolts nearest the tire.
8. Lower the adjusted side.
9. Elevate the right corner, and repeat step 5 through
step 8.
10. Tighten all the bolts to “Torque Values” on page 80.
