A pulley system with snatch blocks works great for removing tree stumps if you set it up correctly. In this episode we make multiple attempts removing tree stumps using basic physics and we finally understand how to configure the pulley system to multiply your force. Multiple techniques are shown with diagrams showing rope configuration to maximize your pulling power with only a few snatch blocks.
