Abstract: A track assembly for moving a vehicle which includes a track having lugs including both drive and guide portions on its inner surface. The guide portions substantially abut against the track rollers of the assembly. Such abutment maintains alignment of the track between those rollers so as to prevent it from moving from side to side and interfering with feeding of the drive portions onto the assembly drive sprocket. Further, the guide portions grab against the drive sprocket to maintain contact of the drive portions therewith. Each of the above functions permits uninterrupted movement of the vehicle since the track is enabled to move in a continued path.

Abstract: A loader linkage having a bucket and boom arm mounted to the loader vehicle by way of top and bottom links, the top link being pivotally coupled with a structural member of the vehicle that extends upwardly from the vehicle frame generally at the rear of or behind the operator station. The top link is coupled to the structural member at a point generally above and behind the operator seated on the vehicle. The linkage establishes a bucket path that extends generally vertically initially and that then extends forwardly through the entire range of upper motion of the bucket. The linkage causes the bucket to achieve maximum reach at the bucket's maximum height. The orientation of the top link also reduces the vehicles tendency to tilt rearwardly onto the rear wheel's during leveling operations.
