Abstract
A fluid heating system for a work vehicle includes a pressurized fluid circuit having a pump for providing pressurized fluid to the fluid circuit. A control module for controlling a first control device is in fluid communication with the fluid circuit, the first control device operable between a first position and a second position. The first position of the first control device permits a load sense pressure to be applied through the first control device, thereby preventing pressurized fluid from the pump flowing to a pressure return tank for heating the pressurized fluid. The second position of the first control device prevents the load sense pressure from being applied through the first control device, thereby permitting pressurized fluid from the pump flowing to a pressure return tank and resulting in heating of pressurized fluid of the fluid circuit.
