Abstract: A floor scrubber machine can comprise a chassis, a scrub deck and a propulsion system. The scrub deck can include a hands-free, double-scrub side skirt mechanism, and a dual mode side blade assembly. The chassis can include a rear squeegee assembly having a self-aligning hanger system with balanced handles. The propulsion system can include a throttle pedal having a button for forward/reverse control, and a control panel having a setting for rescaling the acceleration profile. A disc brush scrub deck can include a brush centering mechanism. A cylindrical brush scrub deck can include an idler end brush cover with self-aligning tabs, and a self-contained drive mechanism.
