Abstract: A trailer coupling for tractive vehicles, in particular agricultural tractors, consisting of two vertical guidance cheeks (7), fitted with lateral spacing to the rear of the vehicle, the guidance cheeks including vertical slots (7a) and a bearing member (11) held detachably at the lower end region of the guidance cheeks, on which a coupling member (12) is arranged for attaching an implement. In the case of a prior art trailer coupling, all forces transmitted from the attached implement to the coupling member used, a ball coupling (12) for example, are conducted via the bearing member (11) into the guidance cheeks (7). Thus this involves the undesirable necessity of having to dimension the guidance cheeks in a robust manner, which in turn leads to space problems within the tail end region of the vehicle. Therefore a trailer coupling is to be created which reduces the load on the guidance cheeks (7), when the forces of the attached implement are conducted into the rear of the vehicle.

Abstract: A sulky apparatus and method are described. The sulky rides behind a self-propelled mower. The sulky apparatus allows the mower operator to ride behind the mower, as the self-propelled mower is guided about a lawn. Common to the sulky apparatus is a swing arm that extends from the mower to the sulky.

The pin is then projected into an aperture disposed in a top portion of the sulky, thus locking the mower and sulky together in straight position alignment. Once locked, the mower and sulky can be driven in reverse.

Abstract: An improvement in or relating to a hitch assembly for connecting a trailer to a towing vehicle. The hitch assembly consists of features which are moveable in a telescopic manner and/or in a rotational manner to allow the adjustable repositioning of a coupling member of a trailer for it to be conveniently connected to a tow ball of a towing vehicle. The hitch assembly consists of ratchet type features that when a movement of the trailer is provided by the towing vehicle, the hitch assembly will move towards a condition, substantially automatically, where the connection between the trailer and the vehicle becomes substantially rigid apart from the degrees of freedom of movement normally provided by the coupling. The ratchet type features can be made in operative to allow for a user to manipulate the position of the tow coupling of the trailer so as to achieve a coupling between the trailer and the tow vehicle without the trailer needing to be in an exact location in respect of the tow coupling of the trailer.
