ABSTRACT:
A loader having a working implement is removed from a tractor by placing the implement and a stand into contact with the ground as spaced apart from each other in the direction of advance of the tractor, disconnecting each of masts from a mount, subsequently advancing the tractor to raise the mast off the mount with the ground contact portion of the stand serving as a fulcrum and cause the implement and the stand to support the loader in a standing state, and thereafter retracting the tractor. The loader is attached to the tractor by advancing the tractor toward the loader in the standing state to set the mount in position in the rear of the mast, further advancing the tractor to incline the stand downwardly rearward and fit the mast into the mount from above, thereafter connecting the mast to the mount and removing the stand.
