Steering System Troubleshooting

No steering

Transmission range-shift lever in PARK position

Shift range-shift lever out of NEUTRAL position.

Loss of electrical power to steering controller (generates STOP ENGINE warning and CCU 55 code)

Check fuse F8

See your John Deere Dealer

Other electrical or hydraulic malfunctions

Check vehicle monitor for warning codes. Refer to Service Codes Section for possible solution

See your John Deere Dealer

RX15494,0000155 -19-06NOV01-1/3

Will not turn as short as desired/expected or difficult to turn under load

Implement causes side loading greater than steering system can overcome when attempting to turn; outside track spins

Raise implement

Slow down during turn or execute turn by doing a series of brief short turns

Let drawbar swing or hitch sway

Add ballast (See Ballast Section.)

See Tractor Operation in the Operating the Tractor Section

Track slips on drive wheel

Check track tension (See Vehicle Monitor)

Wet or slippery material between belt and drive wheel. Clean area and/or change method of operation; do not turn under load

Track slips on drive wheel when backing and turning

Make a series of brief, short turns; back straight for short distance, then stop to turn

Electrical or hydraulic malfunction

Check vehicle monitor for warning codes. See Service Codes Section for possible solutions

See your John Deere Dealer

Tractor drifts or pulls to one side

Implement causing side load on tractor

Adjust implement to eliminate side draft

Let drawbar swing or hitch sway

Add ballast. (See Ballast Section.)

See Tractor Operation in the Operating the Tractor Section

Steering wheel does not self center

See your John Deere Dealer

RX15494,0000155 -19-06NOV01-2/3

Will not turn as short as desired/expected with no load

Electrical or hydraulic malfunction

Check vehicle monitor for warning codes. (See Service Codes Section for possible solution.)

See your John Deere Dealer

Attempting to turn while stopped (loose soil, heavy ballast); steering load exceeds system capacity

Maintain forward/reverse motion while turning

Increase engine speed and/or hold steering wheel against stop for a couple of seconds to allow greater steering force

Will not turn as short as desired/expected (high gear, low engine speed)

Minimum turn radius is naturally greater in high gears and maximum steering pump flow is less at low engine speed

Downshift before turn
