A vehicle hydraulic oil reservoir assembly includes a main reservoir and an auxiliary reservoir. The main reservoir has a lower portion and an upper portion. The auxiliary reservoir has a lower portion and an upper portion. The auxiliary reservoir has a port formed in the upper portion thereof. The lower portion of the auxiliary reservoir is communicated with the lower portion of the main reservoir. A breather vent is in communication with atmosphere. A vent pipe communicates the port with the breather vent.

Reservoir assembly with breather vent

A work vehicle includes a frame and an axle assembly coupled to the frame, including a first axle shaft and coil substantially disposed in an axle housing. A first wheel couples to the first axle shaft of the axle assembly. An axle lubricating fluid is disposed within the axle housing. A cooling circuit fluidly coupled to the axle assembly circulates cooling fluid therethrough. The coil conducts cooling fluid through the first axle housing separately from the lubricating fluid. A cooling fluid circuit is selectively fluidly coupled to the first coil to circulate the cooling fluid therethrough.

Axle cooling using hydraulic return oil

A work vehicle includes a frame and an axle assembly coupled to the frame, including a first axle shaft substantially disposed in an axle housing. A first wheel couples to the first axle shaft of the axle assembly. An axle lubricating fluid is disposed within the axle housing. A cooling circuit fluidly coupled to the axle assembly circulates cooling fluid therethrough. A hydraulic motor fluidly coupled to a fluid circuit includes a device disposed in parallel with the fluid circuit to discontinue operation of the motor in response to a predetermined pressure of at least one of the first and second circuit being exceeded.
