Abstract
A work machine () comprises an operator interface (), an auxiliary electro-hydraulic circuit (or) adapted to operate a hydraulic actuator () of an auxiliary tool () when the auxiliary tool () is attached to the work machine (), and a controller unit () that communicates with the operator interface () and the auxiliary electro-hydraulic circuit (or). The controller unit () is adapted to receive from the operator interface () an electrical setpoint signal representative of a flow setpoint selected by an operator via the operator interface (), and electrically operate the auxiliary electro-hydraulic circuit (or) so as to output flow from the auxiliary electro-hydraulic circuit (or) to the auxiliary tool () at a substantially constant magnitude represented by the flow setpoint. An associated method is disclosed.
