Smyth Trailers has produced a special trailer with forced rear steering. The trailer is based on their already successful Supercube design.

The trailer is 25ft long (7.6m) and 8.3ft (2.55m) wide with an overall height of 12.8ft (3.9m), which gives it a payload capacity of approximately 50 cubic metres. Other sizes are also available.

The forced steering works in conjunction with a mini ball located next to the tractor’s hitch, which in turn is connected via an adjustable push rod to the steering’s hydraulic system.

The push rod forces oil to enter the left or right hydraulic cylinders, depending on the direction the trailer is being towed. As it’s a closed pressurised oil system, the displaced oil forces the steering axles to turn in either forward or reverse, with the front and rear axles steering in the opposite direction of each other, further reducing the turning circle and keeping it in line with the tractor’s track.

The trailer is fitted with a ball-and-spoon hitch for added safety and also the added payload that this system affords.

Attached to the axles are 560/60-22.5 low ground pressure tyres, which reduce soil compaction and increase the trailer’s weight-carrying capability and stability.
