You're right, as I think about it more. So the maximum amount of "push" you can get is limited to the weight you have up front. On the rare days when my 2010 backhoe worked a little bit, it always wanted to tip over backwards on the slightest upgrade. Sometimes I'd go up the hill backwards. One time it stalled on the hill and was balanced very precariously until I went and threw a bunch of rocks in the loader bucket.
With the log scheme I can see the worst case situation is when the log first hits the ground since it's providing NO forward push at that point, but just lifting the nose of the tractor. So, if the log was too long and didn't dig into the mud at all, it wouldn't help you go forward at all. There must be an optimum length of log that will dig in all the way but will still provide enough push.
