The gas spring (53) urges the platform to pivot about the first set of wheels (68) downwardly in the rear and upwardly in the front. The motor (24) for rotating the polishing member (14) is pivotally mounted to the platform (20) by ears (23) so that the polishing member (14) can flushly abut the floor surface. The handle (16) is latched in an upright transport position by a pin (59) received in the first leg (85) of an L-shaped slot (81) formed in a latch (74) pivotably mounted to the platform (20) and is allowed to pivot in operating positions when the pin (59) is received in the second leg (83) of the L-shaped slot (81…
