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.
