ABSTRACT:
multi-operational earthworking machine is disclosed wherein the frame includes a telescopible front wheel assembly to permit a selective varying of the length of the wheel base. A carriage, housing an operator's station, is rotatably mounted on the frame for rotation about a generally vertical axis and carries a backhoe assembly pivotally mounted thereto for working the ground beyond the frame of the machine. A pusher type scraper assembly is also provided beneath the frame between the front and rear wheel assemblies. The scraper assembly is provided with a pair of stabilizer pads engageable with the scraper blade to stabilize the machine during operation of the backhoe assembly.
