HYDRAULIC DRIVE LINE AND HITCHING ASSEMBLY FOR PULL-TYPE IMPLEMENT
摘要
A hydraulic drive apparatus for powering mechanical components of a pull-type crop harvesting unit or other agricultural implement or the like. The apparatus has an elongated extending hitching arm (15) for pivotal attachment to a powered vehicle (20) provided with a power take-off shaft (50). The drive apparatus includes a hydraulic pump (70) for attachment to the hitching arm (15), a mechanical drive shaft (54) for operation of the hydraulic pump (70) upon attachment of the drive shaft to the power take-off shaft (50) of the powered vehicle (20), and connections for hydraulic fluid lines (72, 74) for delivery and return of hydraulic fluid to and from a hydraulic motor for operation of the mechanical components of the pull-type crop harvester. The apparatus may include an articulation assembly (76) to isolate the drive shaft (54) for the pump (70) from movements between the hitching arm (15) and the vehicle (20).
