They can can tight and hard to operate if the mechanism dries out. Too much lubricant attracts dust etc, but if you regularly flush the mechanism with a spray lubricant, there should not be any seizing issues.

Have noted ours is getting a tad harder to remove after around 600km of off bitumen towing in quite dusty conditions. Simple solution is to give the pin and locking pin a flush with silicone spray as this does not attract dust and we use the same technique on our Oz Hitch pin as well. The practice has served us well over many thousands of outback kilometres towing the Ulti in recent years.
Like anything that moves on a 4WD it requires a little TLC on a regular basis

I shall give it an Inox treatment.
Graeme, information I have from Vic TOG is that using the recovery loop is not legal as the chains are above the ball. 'Course given the divergence of opinion on anything towing, this may or may not be correct and may be an individual interpretation :(

Hi All
Last week I had a new tow hitch installed by British Offroad on the Sunshine Coast; great job and great unit. The unit sits about 200mm higher than 'the plough' and makes use of the recovery point, no need to uninstall it. See photos http://www.aulro.com/afvb/d3-d4-rrs/...ml#post2305825 entry #46
:D
I believe the issue is related to the chains "catching" the drawbar as it drops. The information was that they are required by law to be below the tow ball. Now, I know someone is going to request the specific legislation or is going to quote sub-section d, para f, of an Act but that is the info as received.

I understand that individual states have their own regulations but there's no mention of towbar chain attachment height in VSB1, the ADR technical requirements for trailers bulletin.
