Come-alongs are very very slow to use!
Try getting some pulleys, you can then double/quadruple etc your pulling power very easily. (If you have a strong nearby tree to use as the fixed point).
That is what I do when I need to pull something real heavy with my largest tractor (JD 4120 with loaded R1 tires). One snatch block, a big tree, and some 1/2” wire rope can work wonders.
I resently pulled down a big old timber framed barn, that my great great grandad built in 1883,
like it was made of toothpicks and those are 9” and 11” square hand-hewn beams.
