Abstract
A trailer hitch assembly for attaching the tongue of a trailer mower or the like to the drawbar of a tow vehicle, such as a tractor. The assembly includes a first clevis attached to the forward end of the tongue of the trailer for 360.degree. relative rotation therewith. The attachment is by means of a first pin extending generally horizontally and generally parallel with the line of travel of the tractor and mower to thereby accommodate roll type relative movement therebetween. The apparatus also includes a swivel member in the form of a double clevis, with one clevis thereof arranged for rotational attachment to the first clevis by means of a second pin extending generally horizontally and transverse to said line of travel to thereby accommodate pitch type relative movement therebetween. The other clevis of said swivel member is arranged for rotational attachment to the drawworks by means of a generally vertically extending pin, to thereby accommodate yaw type relative movement therebetween. There is thus provided a trailer hitch which will not permit the tractor to be overturned in the event that the trailer is inadvertently overturned, thereby providing a safer mode of operation for the tractor and mower.
