Preventing tractor back flip

[RoyJackson]

The dear professor generalizes.

And you're doing anything different...or, for that matter...any of the posts on this thread (including mine) doing anything other then conjecture based upon theory and a modicum of real life situations sprinkled in? We're all generalizing.

The difference is, this professor has more of an agricultural background then anyone here (although there might be a couple of real farmers posting). I would wager he's has a a pretty good database of tractor incidents to work from too.

THat is the point. The wheels WILL come up. But if properly hitched, it wont go on over/QUOTE]

It won't go over?? Well well what do we tell the folks that did go over?

Just need a little torque that's all.:thumbsup:

I recommended not "pulling" from the rear..ie pull from the front! post #6.

I don't think there has ever been a tractor "back flipping" using this method

No, but a good chance of damaging the gears, transmission or other components.
Also, tires such as R-1's or R-4's are undirectional. You'd have to reverse the tires for traction.
I have pulled from the front on occasion, but that was for a pretty light load (smaller trees, for example).

Maybe I'm missing something but you can still pull from the front in forward gear with the chain or cable attached to the front of the frame

Yeah, I thought you meant pulling in reverse gear.

I suppose you could rig to the front weight bracket, but you'd want to keep the cable or chain low enough that it doesn't foul the tires, hydraulic lines, cables or linkages under the tractor. Also, changing direction might be a problem (if you needed to change direction).

I would think that anyone trying to pull such heavy or restricted loads would take whatever measures to prevent the dreaded "back flip", rather than using a bigger tractor. Just trying to propose methods that answer the OP's question.

I suggested that in the last "tractor flipover backwards" thread a couple years ago and basically got laughed at. I personally would prefer pulling from the front end, but only for a particular situation of short duration such as trying to get a vehicle unstuck, etc. I am NOT suggesting that someone pull their 6ft wide disc harrow from the front end all day long to plow a 100 acre field, just to make that very clear.

While tractor flipovers from the rear are not that uncommon, you rarely ever hear/read of one flipping over from the front end, even with 4x4 engaged. With just the two rear wheels driven in reverse, I would think that the chances get even smaller of flipping one over frontward but I won't say it'll never happen. Murphy's Law, you know?

Yes, I do realize that the ring & pinion gears are designed to be stronger in the forward direction, and not the reverse direction so you may be more likely to break something this way (maybe they should be stronger!:thumbsup. I also realize a tractor won't pull quite as much weight going in reverse as compared to pulling from the rear (and going forward) because of the weight distribution, but again has anyone heard or actually seen a frontwards flip over happen?

Hey xtn, you want to draw up some vector force diagrams for pulling from the front end, and how it will go forwards just before it tips over frontwards??? :confused2: That should be good for another 200 posts in this thread! Sorry, just messing with you! :laughing:

Just speculating but I don't think a majority of back flips come from pulling properly sized implements, I would think most come from trying to pull stumps or other objects that offer more restriction than the operator realizes. ?

Most I've read about were stumps and such. The only one I know of locally (I'd posted this earlier) was a guy skidding a log up a slope. He was rigged (so I heard) to the drawbar, but the slope moved the tractor's center of gravity way aft.
