ABSTRACT:
A work vehicle comprising a motor, a drive unit for driving a ground engaging portion, a torque converter for variably transferring power from the motor to the ground engaging portion, a lubrication circuit for providing lubrication fluid to the torque converter, and a control valve located between the torque converter and the lubrication circuit. The work vehicle further having a linkage for performing a work function, an actuator to controllably move the linkage, a sensor coupled to the actuator to sense a force opposing the actuator, and a controller in communication with the sensor and the control valve. The controller is adapted to command a crowd reduction in response to the sensed force opposing the linkage, whereby the pressure of the lubrication fluid provided to the torque converter is reduced.
