Abstract: A track assembly is formed from an endless track, an elongate guide member, a drive sprocket, and a plurality of track engaging rollers. The endless track has an inner surface having a plurality of parallel circumferential ridges. Formed between the circumferential ridges is a circumferential channel. The guide member is at least partially positioned and closely received within the circumferential channel. The track engaging rollers are arranged in a pair of parallel rows near an outer side of each circumferential ridge. During track rotation, the guide member remains closely received within the channel, and the rollers contact the outer side of the ridges to resist lateral movement of the track. Positioning of the guide member in the circumferential channel, with the rollers outside the ridges, laterally stabilizes the track thereby reducing the risk of the track slipping off the track assembly.

Abstract: A coupling assembly couples an implement to a vehicle having a pickup hitch. The coupling assembly includes a coupler frame attached to the implement. A jack stand member is mounted on two coupling pins which project from the coupler frame. The jack stand member has a first slot which receives the first pin and a second slot which receives the second pin. The second slot forms a first shoulder which engages the second pin to support the coupler frame when the jack stand member is in a ground engaging lowered position. A block mounted to the pickup hitch is spaced apart from the jack stand member to allow it to fall to the lowered position when the coupler frame is uncoupled from the vehicle. The block engages a surface of the jack stand member to raise the jack stand member when the coupler frame is moved towards the vehicle.
