How high you hitch the stump controls how easy it is to tip the tractor back.
If you keep the hitch low, the pull of the stump pulls down on the front opposing the rise from the torque of the back tires. Figuratively when the back tires can't move, the tractor climbs the ring gear in the differential with the pinion gear. That is resisted by the weight of the front of the tractor on its moment arm.
When you hitch high, like axle high, then the pull of the stump doesn't hold the front of the tractor down. When you hitch above the rear axle, the pull of the stump helps the front of the tractor rise.
When you use the three point there is nothing to hold it down on most tractors so if you hitch to a post up high it raises the three point and moves up the hitch point giving the same effect as hitching to the upper link or the axle which makes tipping over backwards very easy.
The 8N I had didn't have a strong enough hydraulic to lift the front end by lifting with the three point alone. I've other tractors that will get the front end very light with load on the three point. Often to the point of requiring steering with the brakes not the front tires.
Stump pulling with a wheel tractor is not a safe operation when pulling from the back. It might be safer to hitch the chain to the drawbar and run it under the tractor and to pull in reverse, but even then to never jerk on the chain.

This story is about the day my Grandfather Brown (true name) decided along with my parents to purchase a new Ford tractor. It wasn't really new except to us. The year was about 1967 and my father found a good used Ford 601 tractor to use on the farm instead of "Bob", our old mule. Now my grandfather had had this mule since the mid 40's and he was getting some age on him. S
