Tool mounting assembly for a surface maintenance machine

A squeegee mount and assembly which cooperate to permit both pivotal and linear motion of the squeegee assembly relative to the machine frame. To avoid contact with a stationary object, the squeegee assembly can be both pivoted and linearly moved relative to the surface maintenance machine, thereby preventing damage to the squeegee assembly and/or the surface maintenance machine. The squeegee mounting assembly includes a mounting arm, a subframe, a return spring coupled between the subframe and the frame, and a stop. A squeegee assembly comprised of a squeegee blade, an arcuate squeegee blade holder, and a link which couples the blade holder to the squeegee mounting assembly. A guard rail is also coupled to one end of the blade holder and rotatively coupled along another end to the frame.
