ABSTRACT:
A self-propelled carpet/tile stripping tool of the walk-behind type includes a drive train including an electric motor coupled through an electromagnetic clutch and a gear reduction box to ground-engaging wheels for advancing the machine in a forward direction when the clutch is energized. The same motor driving the wheels also is coupled to a cutting head member by means of an eccentric drive where the cutting head member is suspended in elastomeric shock mounts to reduce vibration while yet permitting orbital movement of a floor-engaging cutting blade. Finger-tip controls allows selective operation of the drive motor and electromagnetic clutch. The machine is further weighted to increase the frictional engagement between the floor scraper blade and the floor surface and because of the self-propelled aspect, operator fatigue is minimized.
