An apparatus for cutting grooves in a ground surface includes a wheeled vehicle with a tool carrier connected to the wheeled vehicle. The tool carrier is rotatable about an axis parallel to the direction of travel of the vehicle and perpendicular to the direction of travel of the vehicle. A grinding tool for cutting grooves in a ground surface is rotatably mounted to the tool carrier. The grinding tool may be movable laterally relative to the vehicle. A rotatable cam is configured so that rotation of the cam causes pivotal movement of the tool carrier relative to the forward frame. Rotation of the cam moves the grinding tool into and out of engagement with the ground surface.

A floor stripping machine has a support frame with a pair of rear wheels rotatably mounted to the support frame. A motor with a motor output shaft is coupled to a gear reduction box mounted to the support frame. Rotation of the output shaft of the gear reduction box reciprocates a drive plate, which is fixed to a follower plate. Chisels mounted to the follower plate reciprocate therewith.

A surface preparation apparatus has a drive-on wheeled vehicle with a surface preparation tool attached thereto. The surface preparation tool can move vertically and can rotate about two separate axes relative to the wheeled vehicle. The surface preparation tool therefore can float over the contour of a floor being treated.

The surface preparation apparatus includes a motor-powered wheeled vehicle and a grinding head assembly. The grinding head assembly may oscillate relative to the direction of the travel of the vehicle. The weight applied to the surface by the grinding head assembly may be varied from the weight of the grinding head assembly to zero.
