Adjustable Row Crop Width Axles
The Redball
®
Model 680 High Clearance Sprayer has
optional adjustable axles which allow the operator to
increase or decrease the width of the spacing between
the tires. Width adjustment will allow for accommodating
different types of crops, which are grown with different
plant row spacings.The procedure for adjusting the axle
width is as follows:
1. Secure sprayer on level ground, assuring NO forward
or aft rolling of sprayer can occur when elevating a
tire.
2. Utilizing a jack, hoist or forklift: raise one side (i.e.
one tire) off the ground.
3. Secure elevated end with jack stands, braces, or
equivalent, assuring the side of the sprayer cannot
fall, causing a hazard to personnel under the sprayer.
4. The axle tube is very heavy and should only be
moved with the aid of a floor jack or equivalent
lifting system. Loosen the four U-bolts located
along the axle cross frame and slide the spindle and
hub assembly to the new desired width setting. If any
of the axle adjustment u-bolts need to be complete
ly removed, extreme care should be taken to assure
the axle tube weldment is not dropped. Tires should
always be placed equal distance from the trailer center
line, as an offset may cause poor trailing stability.
5. Tighten all axle adjustment bolts to the torque
specified in section E. Replace any bolts or nuts
that have signs of physical damage, especially noting
damage due to corrosion.
6. Remove jack stands/braces and lower unit back
to the ground.
7. Repeat for the other side making certain the
same distance from the centerline is achieved.
Never attempt to adjust the tire width unless the sprayer is
secure, and on level ground. The liquid tank should be
completely void of fluid. Always secure sprayer with jack
stands, braces or equivalent when working under an
elevated unit.
