Warm Transmission-Hydraulic System Oil

Steering, transmission, and hydraulic systems are slow to function when tractor is started in cold weather.

CAUTION: Overheated hydraulic oil may cause personal injury and component malfunctions. To prevent hydraulic oil from overheating, DO NOT hold selective control valve (SCV) or multi-function lever in operating position for an extended period.

NOTE: The rear SCV is preferred, but operator can perform oil warm-up operation at mid SCV.
