Abstract: A device for preventing over-articulation of a trailer towed by a towing vehicle. The device includes a bracket and a pair of opposed shock absorbing members affixed to and extending outwardly from the bracket. The bracket includes a horizontally oriented upper portion, a pair of side portions extending downwardly from the upper portion, and at least one opening defined in at least one of the side portions for connecting the device to a trailer tongue.

Abstract: A Trailer hitch for towing a four wheeled vehicle. The hitch has a fixed in place portion attached to the towing vehicle and a translatable portion attached to the vehicle being towed. The translatable portion is spring biased to a center position. A damper is attached between the fixed portion and the translatable portion to prevent abrupt movement of the translatable portion. The hitch provides controlled lateral movement between the towing vehicle and the towed vehicle to diminish wear on the front end parts and tires of the towed vehicle.

Abstract: A device for stabilizing the two lower steering arms (1) of a tractor, with the lower steering arms (1) actuated by a hydraulically operated power lever (9). The arms are each associated with a side strut (6) with a first single-acting hydraulic cylinder (7) for stabilizing and fixing purposes. A line connection between the first single-acting hydraulic cylinders (7) and the power lever (9) can be effected by a control valve (13). In order to center the lower steering arms (1) and set the arm to a pre-determined dimension of spread, even when no implement is attached, the line (14) which leads to the second single-acting hydraulic cylinder (10) of the power lever (9) contains a pressure-controlled first return valve. A bypass line (21) with a second return valve (22) is provided to lock in the direction opposite to that of the first return valve.
