The Hyland coupling is as simple and easy as a standard 50mm coupling to hitch and unhitch. When hitching up, the head will rotate in two planes to aid alignment. One point to note is that a 50mm ball (rated to 3500kg) with a slightly longer shaft should be used to ensure the coupling seats properly. Often, standard 50mm shafts will not allow the coupling to ‘drop’ on far enough, and the unwary will have their trailer parting ways when least expected – there were no safety or warning aspects for this problem built into the hitch.

Most standard 50mm coupling aren’t particularly low profile, making for damaged rear doors if you’re not careful while opening. A pin is stronger than a bolt. For example, a clevis pin fitting an 8mm hole will fill up the entire diameter. Comparatively, an M8 x 1.25 bolt will only have the 6.65mm core diameter, making it the much weaker option. How strong is a clevis pin? This hitch can be removed from your tow vehicle, even under load from the trailer, making for easy operation. A point to note on the original design for making hitching up easier is to remove the round red side-mounted knob to help hold the pivoting head in position; otherwise, you’ll find yourself unnecessarily holding the head up level. Don’t forget to replace it before driving off! The newer design overcomes that teething problem. The main advantage of the Hyland hitch is that it doesn’t require changing from a 50mm ball; meaning one fitting can be used with both your standard on-road trailer and an off-road trailer.

The horizontal pivoting action is via a solid metal bush positioned where the vertical bolt attaches the whole unit to the tow vehicle. The 90-degree vertical movement (up and down) is via the main (bushed) pin, while the rotational motion is via the main shaft – three simple axis movements. While the original AL-KO Off-road Ball Coupling is no longer available (it has been replaced by a design similar to the old Hyland product) the New Off-road Ball Coupling still utilises a standard 50mm ball, although clamps on differently to a standard ball coupling.

Watch out for all the cheap overseas copies that have hit our shores. While some may have been tested and ADR approved, and some may be designed for our use off-road, I can assure you some fall short of the goalposts and do vary slightly from the original design parameters from which they were copied.

The newer, taller tow pin allows for easy fitting of weight distribution hitches without relying on adaptors. The hanger has both a U-shaped clevis and a V-shaped clevis. In the V-shaped clevis, there’s a hole in the flattened area at the base. The components are joined together with a pin or bolt. Clevis hangers offer vertical pipe adjustments, making them ideal for pipe attachments. Laser-cut designs utilising forged steel, stainless steel and polyurethane, combined with casting methods to ensure precision and strength, 360-degree rotation combined with 70 degrees vertical and horizontal angles, all ensure you’ll tow through almost any angled terrain.

With its pivoting head, the system is somewhat self-aligning and is unhitched via a lift-up T-piece handle at the top of the main pivoting head. The non-corrosive zinc coating should see the hitch looking good for many years.

One point to note is that most 50mm ball couplings are adjustable, and most people don’t set them correctly. See the nut and thread protruding from the snout of the trailer hitch – it needs to be adjusted when the hitch is sitting on the ball to rid movement and noise. You’ve still got metal- on-metal, which will produce wear and tear over time, but a 50mm ball should not rattle if adjusted correctly. The small tongue should be adjusted (via the nut on top of the hitch) to rid the movement of the ball in the hitch. A bolt can function as a clevis pin, but a bolt is not intended to take the lateral stress that a clevis pin must handle. Normal bolts are manufactured to handle tension loads, whereas clevis pins and bolts are designed to withstand shearing forces.
