A side shift backhoe mounted on a sliding frame adapted for sliding transversely along upper and lower tracks of a main frame and in which the sliding frame and one of the tracks have matching chamfered surfaces and the sliding frame and other track have matching horizontal surfaces, and a power device extending between the sliding frame and main frame to effect movement of the sliding frame vertically in one direction to tightly engage the chamfered surfaces and in the opposite direction to cause the horizontal surfaces to engage so that the weight of the backhoe is carried on said other track having the matching horizontal surface.
