ABSTRACT:
A loader device is described comprising a bracket assembly mounted on the tractor adapted to removably receive a tower assembly having a pair of boom arms pivotally secured thereto. The bracket assembly includes a pair of horizontally disposed support members which are positioned substantially above and rearwardly of the front wheels of the tractor. A pivot pin is provided on the forward end of each of the support members. The tower assembly includes a pair of spaced-apart side frames having uprights mounted at the rearward ends thereof. The side frames pivotally engage the pivot pins during the mounting and dismounting operations to provide the necessary clearance between the loader and the front wheels of the tractor. The rearward ends of the side frames rest upon the upper ends of the support members when the loader is mounted on the tractor. The tower is mounted on the bracket assembly in such a way to prevent movement of the tower assembly relative to the bracket assembly during the time that the loader is being operated.
