Thread: D4 Tow hitch ???

You could try a highrise towball. A std ball is actually 1/2" rise (~13mm). You can get them up to 2" that I have found and rated to 3500kg. That can give you an extra ~38mm rise.

The handbook does give "recommended" max dimensions for length out from hitch pin from memory and height, which basically limits you to std hitch and ball.

Thanks gents.

The discrepancy in height is 100mm.
I have ordered a Mitchell Bros hitch, hopefully they aren't too difficult to install.
This will be better for my tandem trailer and will also be much better for a camper trailer down the track.

Centre of tow ball 440mm.
Centre of trailer hitch 540mm (when trailer is level and unloaded).


Trailer unloaded and level.


Trailer unloaded and attached to the D4, quite a bit nose down.

My Mitch hitch arrived today so I will be fitting it shortly.

The instructions list a 90º die grinder under equipment required but there is no mention of grinding in the installation procedure.

Can anyone shed light on this?

Might need to clean out the recovery eye to fit the bush.

Inside recovery eye has some rough casting which needs to be cleaned up to fit the bush.

A dremel and sanding drum will do the job fine.


BTW: in your pics, what height is your Disco set at?

Thanks gents.

In the pics my Disco is at normal height.

The handbook is quite definitive with the maximum hitch dimensions allowed. If you were to exceed these dimensions, say with a ball that is greater than the recommended 6 inches from the pin, would you have trouble with insurance if something were to go wrong?

Hi markorjack,

Does your D4 have 19inch tyres?The reason I ask is that I'm thinking of moving my Mitch hitch over from my 18 inch-wheeled D3 and am looking to confirm that it'll fit ok with the 19inch tyres. A comparison of the 18/19 inch tyre diameters indicates that it should fit ok, but there's nothing like hearing that it actually does!

The Mitch Hitch is a great bit of kit that I cannot rate highly enough.

Thanks,
RickO
