My husband and I have just finished one and one-half miles of fencing. We used six strands of barb wire :cboy: and found that the air driven t-post driver saved the day. WE ordered it over the internet and also the air-compressor as well. It never stopped and drove through some rough Okloahoma dirt and rock. The only concern we now have is the fact that we used the expensive red wire, thinking we were using the best.
