Each to their own! I regularly tow a 2.6 ton excavator on an 800kg twin axle plant trailer.
Bigger holes for safety chains?
Top four are NATO pintle, lower two for a standard ball:
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 surprisedVery bad for 2 axle trailers
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
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
