Abstract
A walk behind powered apparatus for operating working attachments includes a ground engaging carriage with two endless tracks on opposite sides of the frame. A support frame attached to the carriage includes a pair of rearwardly and upwardly extending side plate members with upper end portions that pivotably support a boom and a controller. The boom is arcuately-shaped and has a working attachment at a forward end. The controller includes linkages which are connected to two drive units which enable independent operation of each endless track. The apparatus also includes at least one selectively positionable counterweight that may be moved relative to the vertical traverse plane passing through the center of gravity of the apparatus to increase the operational parameters of the apparatus.
