It's a little tall for pullin stakes but it would work. It is made to pull t-posts when you only have one or 2- if you have very many you get the bucket tractor out
Never used one- but here's where I would start: 1: Place the jack parallel with the T-Post, with two welded slot brackets inserted into the bottom of the T configuration 2: Lift the fulcrum handle all the way up and attach the bracket slot on the chain to the handle 3: Secure the opposite end on the chain to the lowest ground level point of the T post 4: Push down on the handle - pulling the post from the ground. 5: Pick-up testicles from the ground and repeat
