Patent ID: 8528684

Claim:
A work vehicle comprising: an operator seat having a first rotational position and a second rotational position; a rotational position sensor for detecting a rotational position of the operator seat and generating a signal indicating the rotational position of the operator seat; a controller in communication with the rotational position sensor; a charge pump; a transmission having a clutch circuit, a first pressure relief valve capable of relieving pressure at a first pressure, a second pressure relief valve capable of relieving pressure at a second pressure lower than the first pressure, an electro-hydraulic directional control valve biased to a first position and moving to a second position when the seat is in the second rotational position, and a lubrication circuit, the clutch circuit operating at the first pressure, the lubrication circuit operating at the second pressure, the controller causing electro-hydraulic directional control valve to assume the first position and allow the charge pump to operate at the first pressure when the rotational position sensor detects that the operator seat is in the first position.
