LADDER

Run the ladder platform in the 45-degree position to maintain maximum header-to-driveline

clearance and tire clearance. The bottom bi-fold section of the ladder is held in the retracted

position with two gas-charged struts. If the ladder doesn't retract properly then check the

tightness of all the bolts in the hinge positions and make sure that they are just snug. If all of

the bolts appear to be at the correct tightness and the ladder still won't stay retracted then it

is possible that one of the gas-charged struts has failed.

Before operating the combine all shields must be in place and be in working condition.

Shield to tire clearance needs to be checked once the correct tires are installed on the

combine. Check to see if the clearance is correct by having someone watch the tire and

shields as the operator leans the combine to the far right and far left. Some tire selections

require limit switches to be set slightly early to allow enough tire clearance between the left

and right front side panels.

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. Consult your combine's operator's manual or contact your John

Deere dealer for diagnostic and maintenance support regarding the hydraulic system.

IMPORTANT:

Inspect the hydraulic system for leaks, damaged hoses, improper routing, and loose fittings.

Hydraulic hoses that are not routed correctly could become worn from working against

abrasive edges or moving parts. If abrasions or holes do occur, the hydraulic hoses can only

be replaced, not repaired. Do not attempt repairs with tape or cements. High pressure

will burst such repairs and cause system failure and possible injury.

Hydraulic Hose Connections – When tightening loose hoses on the cylinders, pump, etc.,

always use one wrench to keep the hose from twisting and another wrench to tighten the

All adjustments on the hydraulic system are preset at the factory

for optimal leveling and header trim performance. DO NOT MAKE

ANY ADJUSTMENTS TO THESE SETTINGS WITHOUT FIRST
