Hydraulic system may be slow to function when tractor is started in cold weather. Cold oil will not flow easily through the hydraulic system filter (A).

Steering may be slow until system warms up.

Hydraulic system will function normally when oil warms up.

  1. IMPORTANT: To prevent damaging hydraulic pump or relief valve, DO NOT exceed 2—3 minutes warm-up time with steering wheel held in full left or full right turn position or by using the SCV levers. Perform oil warm-up operation at rear or mid SCV.
