Gotta reiterate the absolute need for a dead man hanging off the cables on these winch / cable / come along set ups… heavy blanket, chain whatever to weight down and catch / slow the slingshot if it releases or breaks…

 

I’ve used a prusik knot around cable tied to object being pulled. If cable slips / breaks the prusik will drop the cable…

 It’s a slip knot used in mountaineering to ascend rope or stop an unwanted descent. Slides when not under load. When under load it locks tight.

The workers digging the Erie canal in NY in the 1800's used a system like this for uprooting trees.  Larger wheels (6-8' in diameter) and a pair of actual horses.

I'll bet the Romans and maybe even the Egyptians had something like it, too!

The spare tire idea is really a way to redirect the force, but it doesn't add leverage. The mules-and-lever is simple and effective with a massive increase in leverage.

 

More elaborate, but when you are building a canal and you have a lot of tree stumps, well, this is pretty clever. Essentially a horizontal windlass on wheels. Must've weighed a few thousand pounds.
