ABSTRACT:
A skid steer loader is adaptable to be used with a hydraulically powered attachment. A hydraulic system in the skid steer loader includes a hydraulic circuit providing fluid under pressure. A first auxiliary control valve is coupled to the hydraulic circuit and is movable between a full open position and a full closed position, and is couplable to the attachment. An operator input device provides a variable operator input signal. A controller is coupled to the operator input device and to the first auxiliary control valve. The controller controls the first auxiliary control valve to move a portion of the way between the full open position and the full closed position based on the operator input signal. This provides smoother control over systems which merely operated the auxiliary control valve in a full open or full closed manner.
