Abstract
An agricultural harvesting machine, such as a forage harvester comprises a set of feedrolls () for feeding harvested crop material to a rotating cutterhead (). The feedrolls are driven by a hydraulic drive means comprising a hydrostatic pump () coupled to the engine () of the harvesting machine, a hydrostatic motor () coupled to said feeder means () and hydraulic circuitry () interconnecting the pump and the motor. The circuitry comprises a feeder arrest valve () which is operable to interrupt the oil flow from said hydrostatic motor (), thereby arresting said feedrolls (). The hydrostatic motor () is provided with a flushing valve () for diverting part of the oil flow in said circuitry through said motor for lubricating and cooling the latter. The arrest valve () is provided in said circuitry () between the hydrostatic motor () and the flushing valve (). This arrangement allows for an immediate and efficacious arresting of the feedrolls upon detection of a foreign object in the harvested crop.
