Drawbar pulling question

[etpm]

Reading in another thread about rollovers, and recalling how I almost rolled my 9N over backwards shortly after I bought it made me think some about pulling with my Yanmar YM2310.
When I almost rolled that old Ford over backwards it was because of the way I was pulling and because it was my first tractor. I have learned a lot since then. So, now I'm driving a lighter tractor with more horsepower. It will soon have 320 pounds of wheel weights added. I suspect that the added traction may be a problem when pulling logs if I'm not careful.
I'm thinking that one thing that could increase traction AND keep the front end on the ground would be to turn my drawbar around. This way the connection point to the drawbar would be ahead of the rear axle centerline. Attaching the chain this way would pull the front end down a little and, I think, also transfer more of the pulling force downward, giving the tractor even more traction.
I understand that the angle of the chain would have to be such that the chain would always be slanting downward away from the bottom of the tractor. This won't be a problem. The logs I'm pulling are in places where I can't get the tractor close to, so I usually have 15 or twenty feet of chain stretching between the log and the tractor. I can't lift the end of the log up so sometimes I chainsaw a sort of point on the end of the log so that it won't dig into the ground.
Opinions?

Leave your drawbar like it is. It is designed for pulling from that position. If you are worried, keep a rear blade or box blade attached. Run the chain under it.

My first thought is that if the chain is attached under the tractor any distance ahead of the back axle, turning the tractor might have you driving over the chain. But, maybe not, if you're careful.

If you turn the drawbar around, and pull from the front of it below the back axle, you might be imposing a "peeling" force to the drawbar attachment which it's not designed for. I'd stay with the conventional connection.

I drove more than one N when they were new and never saw one with enough power to do a back flip while pulling at drawbar or 3 point. You should have put wheelie bars on her and kept that old gal.
I reccomend you look at an arch skidder for your tractor until you gain some experience. I've moved logs with an atv hooked to an arch skidder.

Keep your attachment point (whatever it is) BELOW the rear axle. Excessive pulling force applied will then tend to pull your front end down not up.

Typically the factory draw bar is situated below the centerline of the rear axle. Thus it can not exert a force which would pull the tractor over to the rear. Folks typically do the roll over to the rearward, when they have attached the load to something other than the the drawbar socket with something other than a straight drawbar.

Install a drawbar with a dogleg going up in it, and it can pul you over backwards. Hook a trailer hitch onto the 3-point hitch, and lift a heavy trailer tongue, to above the centerline of the axle and give it a tug. The front comes up, and the tractor goes over backward.

All good reasons for in person training rather than u-tube and interweb buds.

The three point arms designed to be loaded in tension, not in compression. If you turned your drawbar to face forward, you would likely bend the arms like pretzels unless you re-enforced the heck out of them. If you are worried about lifting the front end, connect the chain to the front and pull backwards. Maybe what you really need is a bigger tractor.

If pulling from the drawbar, not a drawbar installed on the 3 Pt hitch, it's virtually impossible to flip a tractor over backwards. The front end can and will come off the ground, embrace it, that's one reason tractors have split brakes

re: getting the nose of the log up. I confess to hooking the chain to the drawbar, running it over top of the 3 Pt drawbar, and using the 3 Pt to lift the log slightly when / as necessary to clear obstacles Don't profess to know about this being safe, but the 3 Pt is there to lift and the drawbar is there to pull.

This isn't actually right. The lever arm trying to lift the front end is the vertical component of the vector from your driving tire's ground contact to the attachment point. Only if you could attach the load below ground level would pulling force pull your front end down. Of course, if you're not straddling a ditch and hooking the load to the bottom of a ripper, this is easier said than done.

The lower the attachment point, the better. But there's nothing special about rear axle level.
