I have a B7100 with 3 point hitch. I have some wooden posts that I need to pull out of the ground. Can I use the lift on the hitch to pull them up? The ground is pliable. I have them wiggling. If I can, how should I attach the chains? Using 1 bottom arm? Or should I put a chain to both arms and then attach the lifting chain in the middle? I tried using a chain on my t-post puller but that wasn't happening.
