I need to put a 1600' fence around property, thought I would buy some 8' tall, 4" diameter, treated wood posts, push them into the ground about 2' and put a 6' wire fence up. I was going to get some 100' fence rolls with the small 2' squares on bottom to keep critters out of garden. Need a post driver, seen a few, Shaver, others. This would be a one time project, with repairs and add-ons down the road as I develop my farm. I don't need an auto-leveling, $6,000 driver, a couple of grand maybe, three tops. Any suggestions on driver and fence materials would be appreciated. TIA.
