Abstract
A vertical tapered trailer hitch coupling adapted for mounting on a vehicle hitch mounting frame. The mounting frame attached to an undercarriage at a rear of a vehicle. The vertical tapered trailer hitch coupling includes a vertical tapered collar with a four, equal sided tapered collar hole. A vertical, four equal sided tapered post is received inside the tapered collar hole. The post can be rotated 90 degrees in the collar hole. Mounted on top of tapered post is a trailer ball plate with a trailer ball. Also, the ball plate can include more than one trailer balls. This design allows for two different heights of drop hitches on a single hitch. The trailer balls are adapted for pulling different types of trailers behind the vehicle.
