Purchasing Decisions

Q. What trailer/caravan weight can be towed with the 5 tonne Hitch-Ezy coupling?
A. Trailers weighing up to 5 tonne can be towed behind a vehicle weighing up to 8 tonne.

Q. What is the maximum advised draw bar weight with the 5 tonne Hitch-Ezy?
A. The dynamic testing of Hitch-Ezy was performed with a resting draw bar weight of 500Kg. The coupling withstood a peak down force of 1.5 tonne applied 2 million times during the dynamic testing.

Q. What trailer/caravan weight can be towed with the 3.5 tonne Hitch-Ezy coupling?
A. Trailers weighing up to3.5 tonne can be towed and the advised maximum draw bar weight is 350Kg.

Q. Can Hitch-Ezy be ordered on any new trailer/caravan?
A. Yes. Hitch-Ezy fully complies with all relevant Australian Design Rules. The Component Registration Number for the 5 tonne model is 47868. The Component Registration Number for the 3.5 tonne model is 47869.
We are happy to speak with any trailer manufacturer who is unfamiliar with Hitch-Ezy.

Q. Is retrofitting to existing trailers easy?
A. Yes.  See mounting bolt pattern documents on this website. These patterns will align to the 4 and 6 bolt patterns used by most other coupling manufacturers. 

Q. Do I have to use all six mounting bolts?
A. You must always use at least the front and rear pairs of bolt holes. When only 4 bolts are used the 5 tonne coupling is de-rated to being suitable for towing up to a maximum of 3.5 tonnes. All six bolts must be used for a 5 tonne rating.

Q. My trailer has the coupling mounted between the A-frame members so will Hitch-Ezy fit?
A. The maximum width of the routinely supplied square look Hitch-Ezy’s body is 105mm. There is an optional “Round body” style that is available at no extra cost. The maximum width of this rounded version is 99mm. Technical drawings of both versions can be downloaded from this website.

Q. Can the coupling be mounted on the underside of a drawbar’s coupling mounting plate?
A. Yes. When the body of the coupling is mounted upside down one simply rotates the longitudinal shaft through 180 degrees so that the mouth of the main sleeve is again facing down and able to engage the tow-pillar. There is a mechanical block to rotating the main sleeve through 180 degrees within its yoke. 

Q. Which tow-pillar shank diameter should I order?
A. Order the shank diameter that matches the ball-mount hole in your tow-bar tongue or weight distribution head (WDH). A standard 50mm tow ball has a 7/8² (22mm) diameter shank. A 70mm tow ball has a 1.25² (32mm) diameter shank. Also refer to weight distribution hitch questions.

Q. Is any tow bar tongue suitable?
A. The top face of the tow-bar tongue has to be free of any obstruction within a radius of 71mm of the centre of the ball-mount hole. A thin stainless steel plate bearing a label is supplied with each coupling. This plate is bolted into position with the tow-pillar and thereby establishes that there is sufficient clearance around the ball mount hole for the coupling to come to a jack-knife position without hitting other parts of the tow-bar or WDH.

Q. Is a handbrake supplied with every coupling?
A. Yes. Our handbrake is made from marine grade stainless steel and slots under the rear of the coupling’s body. The handbrake folds down below the height of the coupling.

Q. What is the height of the top of my drawbar relative to the top of my tow-bar’s tongue when they are connected with a Hitch-Ezy coupling?  
A. They will be at the exact same level when the supplied 20mm thick spacer is not used.

Q. Do mounting bolts come with every coupling?
A. All couplings are supplied with high tensile mounting bolts, appropriate washers and nyloc nuts.

Q. Will opening the barn door or tailgate on my towing vehicle result in it hitting against a fully engaged Hitch-Ezy coupling?
A. The maximum height of the fully engaged 5 tonne coupling is 120mm above the surface on which the tow-pillar is mounted. When the 20mm thick WDH spacer is used the distance is 140mm but mounting the WDH head one hole down on its drop shank can offset this increase.
The 3.5 tonne Hitch-Ezy has a height of 135mm.

Q. Does Hitch-Ezy have an anti-theft mechanism?
A. Yes. In the 5 tonne model there is a hole for a padlock below the stainless steel button that has to be pressed before the lid can be rotated to the release position. The supplied dummy tow-pillar can therefore be padlocked inside the coupling to deny hitching up. When hitched up the dummy tow-pillar stores inside the aluminium tow-pillar cover. It is not legal to travel with the coupling padlocked to the tow-pillar.
The 3.5 tonne model has a padlock hole in the yoke arm. Simply rotate the sleeve beyond horizontal and the padlock will preclude it facing downwards to engage on a tow-pillar.

Q. Can Hitch-Ezy be used with a Mitchell Hitch?
A. Yes Hitch-Ezy is fully compatible with the Mitchell Hitch www.mitchhitch.com.au that is specifically designed for Land Rovers and Range Rovers.

Q. Can Hitch-Ezy be used on a torsion bar weight distribution hitch?
A. Yes. Hitch-Ezy does not move the point of articulation back from the WDH’s ball mount hole and therefore does not disturb the geometry that the WDH manufacturer intended.

Q. Why is the tow-pillar height raised with a spacer element when it is mounted on a WDH?
A. The “wings” of the WDH hold the torsion bars and they present an obstruction to down angulation of any coupling at a jack-knife position.  Hitch-Ezy pivots at only 32 mm above the surface on which the tow-pillar is mounted while a 50mm tow-ball coupling pivots at 50mm above the surface on which the tow-ball is mounted. To preserve the range of down angulation deemed necessary by the WDH manufacturer we have included a 20mm thick spacer to raise our pivot level to 52mm when it is used on a WDH (See technical information tab for tow-pillar fitting diagram)

Q. Which WDH systems should I choose?
A. We are not in a position to pass judgement on the quality of WDHs produced by an increasing number of manufacturers. Some are cast and some are fabricated. Some have a 7/8” ball-mount hole, some a 1.25” ball-mount hole and others a 1.25” ball-mount hole with a readily removable flanged reduction sleeve down to 7/8” diameter. If your trailer weighs above 3.5 tonne you would be best to use a WDH’s with a higher rated towing capacity and these usually have a 1.25” diameter ball-mount hole.
The maxim that a chain is only as strong as its weakest link applies. You need to take account of your towing vehicle’s rated braked towing capacity (BTC) and the strength of the tow-bar and any WDH.
Lovells Springs offers a 4 tonne BTC upgrade for 200 series Toyota Landcruisers which exclusively uses our 5 tonne Hitch-Ezy as the coupling component of that upgrade.

Q. Can Hitch-Ezy be used with an Andersen Hitch?
A. Yes we produce a special tow-pillar that has an integral tapered lower shaft to suit the Anderson Hitch. Please contact us for details as there were two versions of the Andersen with different taper angles.

Q. What is the purpose of the thin stainless steel plate that has a label on it?
A. This plate is bolted into position with the tow-pillar and thereby establishes that there is sufficient clearance around the ball mount hole for the coupling to come to a jack-knife position without hitting other parts of the tow-bar or WDH.

Q. Do I always use the 20mm thick spacer that is below the O-ring bearing base washer fitted to the tow-pillar?
A. No if using a tow bar tongue. If you are using a WDHs the spacer must be used. 

Q.  What is the supplied 6mm thick stainless steel plate with two holes for?
A. It fills in the slot at the rear of the coupling if the supplied handbrake is not used.


Q. What happens if the rotating lid is not in the default open position when it is presented to the tow-pillar?
A. This could occur if the dummy pillar is absent and someone has triggered the locking mechanism by pocking something up inside the coupling. The coupling will not be able to descend to full engagement and locking-on will not occur so it is not safe to tow. Always check that the coupling has fully descended to engulf the O-ring on the base of the tow-pillar.

Q. What can make the rotating lid difficult to turn to the open (release) position?
A. When the locking ball bearings inside the main sleeve are under load it becomes difficult to turn the rotating lid. This will occur if you wind up the jockey wheel before rotating the lid.

Q. Does Hitch-Ezy automatically lock once it is fully engaged on the tow pillar?
A. Yes. The lid will rotate back to establish primary locking and then the secondary locking button engages.

Q. Will Hitch-Ezy disengage smoothly if there is an odd angle between the towed and the towing vehicles?
A. Yes. 

Q. Will Hitch-Ezy disengage smoothly if there is residual load between towed and towing vehicles?
A. The geometry of the coupling and tow-pillar guarantees that as the jockey wheel is wound up the coupling will always rise and roll-off in the direction of any residual towing force. The sleeve will never hook under the head of the tow-pillar as occurs with couplings based on a tow-ball.

Q. To connect do I have to use the reverse-in/roll-over coupling technique seen in the video?
A. No. Some people prefer coupling by positioning the mouth of the main sleeve generally over the tow-pillar and then allow it to self align on descent.

Q. Do I lubricate the tow-pillar?
A. Yes keep the tow-pillar and the top face of the base washer lubricated with high-pressure grease at all times.
Always use the dummy pillar and tow-pillar cover when disconnected to avoid contamination with grit.
