How to design pulley system for pulling out tree stumps

[EXF]

Could a Bunnings adviser provide a list of items from Bunnings to design a mechanical advantage pulley system (at least 2:1) for pulling out a tree stump? The anchor would be a large nearby tree.

Hi @EXF,

Welcome to the Bunnings Workshop community, it is fantastic to have you with us.

How big a stump are you looking to pull out?

The best option is something like this Gorilla 2000kg Lever Block With 1.5m Lift, which has the pulley system built in.

You would need to grab a couple of Gorilla 2000kg 3m Polyester Round Slings to attach the lever block to the tree and the chain around the stump, then pull the lever to slowly pull the stump out.

Let me know what you think and if you have further questions, please don't hesitate to ask.
