Abstract: A working apparatus includes a body, an engine, axles each carrying ground engaging wheels or tracks for moving the apparatus over the ground, an operator's cab mounted on the body, and at least one working arm supported at or adjacent one end on the body at a position for movement relative to the body, the arm being adapted to carry a working implement at or adjacent a second end thereof, and wherein one of the front and rear axles is suspended from the body by a suspension system which is adjustable independently of the other axle to raise the body to a fully raised position in which an uppermost part of the body is at a maximum height above the ground and a fully lowered position in which an uppermost part of the body is at a minimum height above the ground.

Abstract: A working apparatus includes a body, an engine, a front axle and a rear axle, the axles each carrying ground engaging wheels or tracks on which the apparatus may move over the ground, the apparatus further including an operator's cab mounted on the body, and there being at least one working arm supported at or adjacent one end on the body at a position for movement relative to the body, the arm being adapted to carry a working implement at or adjacent a second end thereof, and wherein one of the front and rear axles is suspended from the body by suspension means which is adjustable independently of the other axle to raise the body to a fully raised position in which a plane in which an uppermost part of the body lies, is at a maximum height above the ground and a fully lowered position in which the is at a minimum height above the ground.
