In the process of helping Mum & Dad move out to a new property we decided to take my ute and go for a tour, right up the back. Apparently to ground up the is pretty boggy and we managed to get my ute stuck in there. The ground was solid enough until after you drove over it. Once you did that and disturbed the crust then all the loose soft stuff below would just let you sink.
This may have had something to do with why we got stuck.
We ended up getting a set of recovery tracks. (Not this brand but similar) and all of a sudden we were out. These things worked so much better than we thought. Even my 2wd ute with an open diff was fine. Until I reversed a little close to a tree for comfort and had to stop again.
The first one goes free.
