Towing Hitch

[Jean Mercier]

For those who have doubts about the trailer hitch height, I could make the picture below at my dealer today (no towball mounted yet), height is about 42 cm to the lower part of the plate, or 17 inches.

Thanks - out of curiosity I just measured my new defender (US) and it is 17" to the bottom of the tow hitch hole. From your picture the IG hole starts about 20". So the IG tow hitch looks like it is 3" higher than a new defender. Very good to know.

Very bad for 2 axle trailers

The adjustment holes seem to be different diameters .
4 one size 2 larger.

Possibly, I also won’t ever tow anything close to 3.5 tonnes, I personally think it’s madness to tow anything heavier than the tow vehicle, for me about 2.5 tonnes and 250kg ball weight is the most I would contemplate.

Each to their own! I regularly tow a 2.6 ton excavator on an 800kg twin axle plant trailer.

V8 diesel range rover sport pulls it and stops it very confidently. Engine breaking from the RRs 6 speed is efficient enough when coupled with the trailers brakes.

I wouldn't be happy towing it with a 4 cylinder double cab pick up though. Looking forward to the Grenadiers towing manners as its similar power to the RR, but with 2 more gears and more weight

Just slide one of these into the socket

Bigger holes for safety chains?

It's sound advice you don't go through any 'washouts' or culverts at speed with these on, you'll soon know you dont have an off road trailer.

Top four are NATO pintle, lower two for a standard ball:

I was more comparing for Europe as they probably don't have anything like the D035 or similar

Yes, they all are made for special usage. I think the lower ones are for the European solution (ball) the upper four for a clutch/hook (don’t know the English word, sorry) and the rectangular hole for the Oz and US adapters. Does that make sense to you?

No for a NATO tow bar that has 4 M12 bolts

Ifor Williams trailers recommend tow hitch at 485 to 535mm. I must admit that when I checked I was surprised

 

[Spjnr]

The air suspension systems adjust their height automatically though.

The INEOS has to account for being loaded up, and with ball weight of a trailer, all with steel springs.

We know the rear axle articulation is really good for a vehicle with its payload, so it makes sense the hitch starts higher and will "droop" to accommodate the spring rate. As soon as mine turns up ill hitch my 3.5 ton set up on the back and take some snaps

 

[bigleonski]

Yeah springs are an interesting one. Since we found out a while ago that they have varying springs they can apply given various accessories you add to the vehicle, I’m surprised, and a little disappointed, that you can’t nominate say springs to cater for 200kg extra weight in the back based on your intended use. It’d save modifying it soon after delivery. Given the suspension is apparently so well sorted perhaps just getting airbags added will do the job for towing or loading up.

I don't believe that figure. I Googled it, but it doesn't look right especially when compared to the EU regulations. I think something was lost in the searching. I have 3 IWTs so when I get a chance I'll dig out the actual manuals.

Top 4 holes for NATO, bottom 2 for EU tow ball

 

[Hannes01]

what happens when the trailer hitch is 50 cm high, the IG is not loaded and I am attaching a 3.5 to trailer with a vertical load of 350 kg.
does the IG stand on the street like a boat accelerating?

The hitch hight seems a little high for me was going to bolt a drop plate on.

Can always bore them out to make all 5 holes the same size or bush the lower ones to M12
