Abstract
A tractor has a main frame with a fore and aft body portion and a transverse rear axle housing, and includes a pair of hydraulic outlets. A transverse upright U-shaped member depends from the body portion of the tractor and has a central fore and aft socket, and a pair of rearwardly open V-shaped latch elements are connected to the tractor axle housing. A separate backhoe has a forwardly extending frame portion having a probe at its forward end that is insertible into the socket and has a pair of transverse pins extending outwardly from opposite sides of the frame for engagement with the V-shaped latch elements. The backhoe is mounted on the tractor by backing the tractor toward the backhoe with the tractor wheels straddling the fore and aft backhoe frame portion. Backhoe control valves are then connected to the tractor hydraulic outlets, so that the backhoe frame can be adjusted to a height and attitude wherein the probe is aligned with the socket on the tractor and the pins are aligned with the latch element on the axle housing. The tractor is then backed until the probe enters the socket and the pins engage the latch elements, and the pins are then locked into the latches.
