Important tire and tread width restrictions apply to the use of combines equipped with the Model 2970H Leveling system that are intended for use on slopes exceeding the maximum leveling capability. See the “Slope Restrictions” section of this manual for important details of these restrictions.
MECHANICAL ADJUSTMENTS WIDTH – Slope MODEL 2970H TREAD Restrictions The Model 2970H Leveling System is designed around a main undercarriage length of 114.5” or 122.5”. The 114.5” undercarriage is designed for use with dual tire packages where 120-180” tread spacing is preferred for 30” rows. Use of the 114.5”...
145” tread spacing. The minimum allowable tread width for use on a Model 2970H leveling system is 145”. The 145” tread spacing is prohibited from use on slopes that exceed 27% or the maximum leveling capability of the combine.
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...
REAR AXLE TOE IN If the rear tire and wheel size changed after the proper sized rear tires were installed the toe in should be checked. Consult your combine’s operator’s manual on the correct toe in for your tire and wheel size. TRANSITION DRIVE CHAIN Check to see that the transition drive chain is in proper alignment and has proper tension.
HYDRAULIC SETTINGS Refer to the Hydraulic Safety section for precautions regarding the hydraulic system. The Model 2970H Leveling System uses an auxiliary pump and single station manifold for its leveling hydraulic requirements. It utilizes the combines original auxiliary hydraulic system for lateral header tilt control.
Do not make any repairs to the cylinders, disconnect valves or any hoses connected to the cylinders, counterbalance valves, bulkhead mount or manifold without first contacting your authorized Hillco dealer. These hydraulic components stabilize the chassis of the combine. Improper repair or replacement of these components could lead to uncontrolled leveling of the combine’s chassis.

TIRE INFLATION Keep the tires properly inflated to the pressure shown in the inflation pressure tables for the front and rear tires. Both under-inflation and over-inflation are detrimental to tire life. Don’t re-inflate a tire that has been run flat or when there is obvious or suspected damage to the tire or wheel components.
