ABSTRACT:
A floor scrubber is disclosed including a frame including a drive wheel, rear wheels, brushes, vacuum squeegee system, batteries, solution tanks, and an operator seat. The rear wheels are rotatably mounted on the opposite ends of a steel rod. Arms are attached rigidly to the axle and each include a cylindrical pivot in which an elastomer bushing is press fit. Pivot pins extend through first and second pairs of first and second plates and the elastomer bushing for pivotably mounting the arms to the frame while isolating any transmitted vibrations. Elastomeric isolator mounts are provided each including a frusto-conical shaped body and each having a nut embedded in the lower end for threadable receipt of a bolt passing through an attachment plate attached to the axle. The upper ends of the elastomeric isolator mounts each include a plate secured thereto and secured to the frame.
