34 - Scrub System
Functional Description
Overview
The scrub system includes the scrub brushes, scrub brush motors, side squeegees, and the scrub deck
actuator which lowers and raises the scrub deck.
The scrub deck actuator lowers the scrub brushes any time the scrub system is enabled. The brush motors
switch on when the drive pedal is moved from the neutral position. The operator can enable the scrub system
independent of the solution and recovery systems to scrub without adding or picking up solution.
