发明名称 Tractor with cargo box and removable hitch ball
摘要 A tractor having a cargo box and an axle mounted hitch ball in which the hitch ball projects upward through an opening in the cargo box floor. This arrangement enables the ball to be used when the cargo box is mounted to the tractor. Furthermore, since the ball is mounted to the axle and not the cargo box, greater load carrying capacity is achieved and the hitch can be used when the box removed from the tractor.
