Rear Axle Weighting; Rear Axle Extension Positioning - Hillco 2970H Operator's Manual

REAR AXLE WEIGHTING

The HILLCO Model 2970 Leveling System is designed to transfer enough weight to the rear
axle of the combine for proper balance that no additional weight is needed. If the operator
determines that additional weight is needed on the rear axle to ensure optimal down hill
performance it can be accomplished by adding:
1) Calcium Chloride in Rear Tires
2) John Deere Rear Wheel Weights
Use caution when using individual turning brakes. Installation of a Hillco Leveling System
transfers additional weight to the rear axle of the combine. Excessive braking to turn can
damage your combine chassis.
The responsibility for making the final determination of appropriate
When first operating the Model 2970 Leveling System in hillside conditions, begin operation
on gradual slopes and work up to more severe slopes only after you have determined that
rear axle weighting is appropriate for downhill maneuvers. The first indication of insufficient
rear axle weighting is sluggish or unresponsive steering while traveling down hill. This effect
will worsen if the operator decelerates. Make sure rear axle weighting is sufficient for safe
down hill maneuvers, under normal deceleration, in your most severe down hill conditions.
Use of grain tank extensions is strictly forbidden. Use of such extensions
voids both the Hillco and John Deere new equipment warranties.

REAR AXLE EXTENSION POSITIONING

The rear axle on the combine is designed so that the axle extensions may be bolted in two
different positions to adjust the rear height of the combine. The rear axle extension position
may need to be adjusted after the correct tires and header are installed on the combine. The
combine should sit level to two inches high in the rear. If it does not, then the axle extension
position will have to be adjusted and the tire size may have to be changed. Consult your
combine's operator's manual for more information on the proper stub axle position.
rear axle weighting lies with the operator.
