摘要： A surface maintenance machine comprising two front wheels, at least one rear wheel, a motive source for providing motive force to at least one front wheel to drive the machine on a surface. Embodiments also include an operator platform allowing an operator to stand thereon extending at least partly around the rear wheel, for supporting an operator in a standing position with the operator's feet on either side of the rear wheel.

摘要： A surface maintenance machine comprising a body having a forward section, a middle section and a rearward section, wherein the forward section is positioned to the front of a transverse centerline of the machine, the middle section is generally centered on the transverse centerline and a rearward section positioned to the rear of the transverse centerline. A storage chamber can be defined in the middle section and enclosed by a front wall, a rear wall, lateral walls, a generally planar top surface, and a generally planar lower surface, such that the storage chamber is generally isolated from components of the surface maintenance machine. The storage chamber can have a storage chamber bottom surface with or below a top surface of at least one battery positioned in the forward section.

摘要： A surface maintenance machine is provided having a maintenance head assembly positioned substantially within an envelope of the machine. The maintenance head assembly has at least one maintenance tool attachable thereto. The machine also includes a tool eject mechanism positioned below an upper surface of the body. The tool eject mechanism can generate a drop force sufficient to overcome the force between the maintenance tool and the maintenance head assembly. The tool eject mechanism can have an eject button extending above the upper surface of the deck. The eject button can be actuable by at least a portion of the upper surface of the body of the machine when the maintenance head assembly is raised toward the upper surface of the body of the machine beyond a transport position into a tool eject position. When actuated, the tool eject mechanism can eject the maintenance tool from the maintenance head assembly
