Pivotable shields for disc mower-conditioner |
摘要 |
A crop harvesting machine having a disc cutterbar is disclosed wherein the shields covering each individual disc cutter unit are connected to a transverse rotatable shaft so that the shields can be pivotally moved between a lowered operative position immediately above the disc cutter unit and a raised inoperative position, wherein convenient access can be had to the disc cutterbar for service and maintenance thereof. The shields are connected to the shaft by mounting tabs having a downwardly depending leg that engages a stop on the header frame to prevent the shields from lowering into a position that would interfere with the rotative operation of the disc cutters. A spring-loaded pin and bracket control mechanism is also provided to selectively lock the shields in either the lowered or raised position by controlling the rotative position of the shaft.
