Product Overview
If a loader hydraulic function is locked out or the spool lock does not release correctly, the control-valve solenoid is one component to inspect. This replacement is intended for compatible lockout-valve arrangements, including selected Case and New Holland skid steers and compact track loaders. Electrical and control problems elsewhere can cause similar symptoms.
