METHOD AND APPARATUS FOR ATTACHING A LOADER TO A TRACTOR

METHOD AND APPARATUS FOR ATTACHING A LOADER TO A TRACTOR A method and apparatus for quickly mounting a loader on a tractor which eliminates need for loose connecting pins or bolts and tools. A pair of slotted brackets include sliding wedge blocks which automatically secure the mast post pins in position during mounting. The mast post pins are moved into the slots, and then the forward portion of the loader frame is rotated upwardly about the axis of the pins to engage forward mounting structure. The tractor is then driven forward to slide the mast post pins into the respective slotted brackets. Thereafter, the boom cylinders are actuated to rock the loader frame about the forward mounting structure and move the mast post pins into vertically disposed portions of the slots and to permit the wedge blocks to slide into their latching positions. A handle operated cam arrangement moves the block away from the slot portion for dismounting the loader. The slots are angled to help break the loader frame away from the brackets during dismounting without requiring excessive load drag. Pivoting hose support structure and a forwardly projecting hose bracket assembly minimize hydraulic hose length and reduce hose routing problems both during loading and mounting/dismounting operations.
