Abstract
Abstract A guide surrounding a trailer hitch ball protects the bumper and the rear end of the vehicle from damage by the trailer hitch member during connection thereof, and comprises a plate secured under the trailer hitch ball and having vertically extending wall portions which join at the rear of the trailer hitch ball in an obtuse dihedral angle. The guide functions to guide the trailer hitch member into cooperating engagement with the trailer hitch ball carried on the vehicle without allowing the same to engage the bumper or rear end portion of the vehicle. The side walls of the guide are sufficiently high to protect the trailer hitch ball from engaging and locking with the bumper of a vehicle used to push the vehicle having the trailer hitch ball installed.
