The necessary pieces for this are quite simple.
A heavy duty nylon tow strap connects to the truck. At the other end of the strap is a somewhat long piece of chain that attaches to the stump puller.
The pulling device is built from the ground up like this: A log, split lengthwise in half forms the two bottom pieces that the device pivots on the ground over.
Spiked to those are two 6"x6" posts that are held together by nuts on the outside of a very long, threaded bolt.
At the top holding the posts together is a steel plate that has a 2" square tube welded to it. A "v" notch is cut into the top of the square tube and this is where the chain from the tow strap gets wedged.
