Zusammenfassung:The invention pertains to an agricultural harvester (100) comprising a self-propelled vehicle (102); a feeder house (104) coupled to the vehicle (102) to pivot about a laterally extending axis (116); left and right feeder house lift cylinders (108, 110) coupled between the feeder house (104) and the vehicle (102) to lift and lower the feeder house (104) with respect to the vehicle (102); and a hydraulic circuit (122) coupled to the lift cylinders (108, 110). It is proposed that the hydraulic circuit (122) is configured to block fluid flow from the cylinders (108, 110) during normal harvesting operation and/or transport thereby reducing twisting of the feeder house (104).
