  • Patent number: 10981416
    Abstract: A track work vehicle includes an axle input shaft defining a first axis of rotation, and a differential gear case having at least one planetary gear set. The track work vehicle includes a track drive system contained, at least in part, in the differential gear case. The track drive system includes a first gear coupled to the axle input shaft and a second gear coupled to the first gear. The track drive system includes a bevel gear assembly coupled to the second gear and a bevel gear set coupled to the planetary gear set. The track work vehicle includes at least one drive axle coupled to the planetary gear set and a drive wheel for driving a continuous ground-engaging track. The drive axle has a second axis of rotation that is vertically offset from the first axis of rotation and substantially coaxial with a centerline of the drive wheel.

  • Patent number: 10207581
    Abstract: A work vehicle includes a multi-mode power distribution assembly that selectively distributes power from a drive shaft between a first axle and a second axle. The power distribution assembly includes a plurality of clutches, each moveable between an engaged position and a disengaged position. The power distribution assembly includes a first mode, a second mode, and a third mode. In some embodiments, the first mode may be a four-wheel drive mode, the second mode may be an all-wheel drive mode, and the third mode may be an overdrive mode. Also, a park mode may be provided, wherein the clutches are in the engaged position.
