Tire Selection - Slope Restrictions; Header And Combine Connection - Hillco 2970H Operator's Manual

On Model 2970H leveling systems the 145" tread width can be achieved by
mounting the final drives directly to the undercarriage and dishing the stock combine
single wheels inward on the 114.5" undercarriage. Check the tread width using a tape
measure to insure your machine is not operating on less than the minimum 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. Dual tires are required for
combines intended for use on slopes greater than 27%.

HEADER AND COMBINE CONNECTION

Refer to the John Deere Combine STS Operator's Manual for instructions on
connecting the header to the combine.
Note: Some headers may require lengthening of the hydraulic hoses that couple from the
header to the combine to allow for maximum rotation of the header during the installation.
All John Deere headers require a HILLCO Header Kit to function properly during rotation of
the transition.
