The Bailey Electro-Hydraulic Third Function Kit is used to add functionality to a front- or rear-mounted skid steer-style attachment, such as a backhoe, grapple, auger, forks, broom or blade. Adds functionality by utilizing the existing power beyond function on your tractor’s valving. Kit comes with a D03 solenoid valve, manifold and mounting plate, plus diodes, wiring harness, Sure Grip AU series control handle, and quick-connect hose adapters. Kit does include installation and wiring information, but does not include hoses.
