An attachment device for a tractor of the type including a front end loader bucket and a rear mounted backhoe comprises a rear axle and ground wheels for positioning beneath the backhoe tower and attachable to the rear of the tractor by forwardly extending straps. Beneath the bucket is permanently attached a kingpin device formed by a plate and pin mounted upon a bracket which is so shaped that the pin and plate are wholly above the plane of the lower wall of the bucket so that the bucket can be normally used with the kingpin devide in place and such that when the bucket is fully retracted the kingpin is presented vertically downwardly. Thus the bucket can be positioned upon a conventional fifth wheel of a road tractor.
