HYDRAULIC DRIVE ARRANGEMENT FOR THE CUTTER OF A PULL-TYPE CROP HARVESTING MACHINE |
摘要 |
A pull-type crop harvesting machine has disk cutter carried on a frame mounted on ground wheels with a hitch arm extending from the frame over the header to a hitch connector of a tractor. The hitch arm is mounted for pivotal movement about a generally upright axis such that in a first position the tractor tows the frame in echelon to one side and in a second position the tractor tows the frame in echelon. The disks are hydraulically driven by a pump at the front end of the hitch arm and a motor at the frame with the hydraulic circuit including a sump tank defined by a hollow interior of the hitch arm and a cooling radiator defined by a tubular frame member which is preferably located at the disk drive as a support therefore as it is cooled by the air flow from the disks and contact with the crop and carries a low volume of fluid.
