Abstract
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.
