Overview
The cylindrical scrub system includes the main scrub deck and hopper, the two hydraulic brush motors,
the hydraulic lift cylinder that lowers and raises the deck, and the associated hydraulic solenoid valves.
The dual-displacement, low-speed (accessory) pump (1.20 CID) powers the two scrub brush motors and the
hydraulic scrub lift cylinder.
The scrub lift cylinder is controlled by two proportioning hydraulic solenoid valves that work together, on
opposite ends of the lift cylinder, to produce the desired main scrub deck pressure.
