Beschreibung
Zusammenfassung:	A work machine (10) comprises an operator interface (30), an auxiliary electro-hydraulic circuit (22 or 322) adapted to operate a hydraulic actuator (16) of an auxiliary tool (12) when the auxiliary tool (12) is attached to the work machine (10), and a controller unit (24) that communicates with the operator interface (30) and the auxiliary electro-hydraulic circuit (22 or 322). The controller unit (24) is adapted to receive from the operator interface (30) an electrical setpoint signal representative of a flow setpoint selected by an operator via the operator interface (30), and electrically operate the auxiliary electro-hydraulic circuit (22 or 322) so as to output flow from the auxiliary electro-hydraulic circuit (22 or 322) to the auxiliary tool (12) at a substantially constant magnitude represented by the flow setpoint. An associated method is disclosed.
