ABSTRACT:
A burnishing floor polisher (2) includes a frame (4), an engine (6) mounted on the frame, and a rotary brush or pad (8) mounted through a universal joint (10) to a rotary shaft (12) supported from the frame, enabling flush engagement between the brush and the floor notwithstanding tilting of the frame. Left and right wheels (20, 22) on left and right axles (36, 38) support the frame for forward-rearward movement, and are adjustable forward-rearward relative to the frame for balancing the frame forward-rearward about the wheels as a fulcrum. A pulley and drive belt system (24) couple the engine to the rotary shaft for driving the rotary brush through the universal joint. An electromagnetic clutch (26) is provided for engaging and disengaging the coupling system from the engine. The disclosed subject matter is particularly characterized by its heavy grade durable construction minimizing down-time in industrial burnishing operations.
