Scrub System, Disc
Functional Description
Overview
The SC6500 disc models use rotary brushes powered by permanent-magnet motors and gearbox assemblies.
The 40” decks have two scrub brushes that are both powered by one 3 HP motor/gearbox assembly. The 45”
and 48” decks have three brushes, each powered by a separate 1-1/2 HP motor/gearbox assembly.
The scrub deck lift actuator raises and lowers the scrub deck, and automatically adjusts the deck height
while scrubbing to maintain the desired scrub pressure.
