Less than 1% FRONT rollovers is probabally 99.9999% of people pull with the rear so that number is a bit skewed. And of the 15% rear 14.9999999% probabally weren't pulling from the drawbar.
Bottom line best adcive for the new guys, call your tractor manufacture and explain to them in detail what you will be pulling (ie a tree top, stuck truck, etc) and ask them if you should pull from the drawbar or loop a chain around the front axle![]()
The study I read didn't have any detail info on front or rear rollovers and where the attachment point was in each case. It would be good to know that (or any statistics in that regard) but I haven't been able to find any information on that. I think it would surprise a LOT of people on this forum.
It's not just the horizontal pulling force to be concerned about. You also have to consider the vertical (downward) force on the drawbar. For instance, if you are towing a big, heavy trailer (with round hay bales for instance) and they shift and roll forward, the sheer increase of the weight of the trailer tongue pressing down on the drawbar can raise the front of the tractor up (assuming the drawbar doesn't bend down with the increased weight), or at least make the front end a lot lighter.
The '81 JD 750 I had years ago came with a drawbar that was 2" wide by 1.5" thick and maybe two feet long. Well, one end was bent such that it was about 2 inches off of centerline of the bar. I would like to know the story behind that one!
