Man... Reminds me of working with my granddad on his farm. His favorite method was using two people, a chain, and a tractor with a hook welded onto the top/head the bucket. Hook the chain on the bucket, wrap the other end of the chain around the post and pull. We did a LOT of fence that way. We also drove a lot of posts with the tractor. I would hold the post in place while he smashed it down with the bucket. Maybe not the safest method, but it got the job done! 😂
