I don't know if the square edges will make a difference one way or another. The thing I like about the log is that it's heavy. Much heavier then a railroad tie and impossible for me to pick up. The weight allows it to knock down the high areas and move the dirt to the low areas.
The cyclone fence smooths it all out and makes it pretty. It also pics up branches and will pull some plants out of the ground. At first, I tried to keep it clean and get those branches out of it, but now I don't even pay attention to whats caught in there. It will work it's way out in time and other stuff will work it's way in. Nothing will stop it, so it's just part of the process.
The cyclone fence that I had was from a short 4 ft fence. I cut it in half and overlaped it. The log is 8 feet wide, and the fence is 7 feet wide with a foot overlapping. I laid out the fence and rolled the log into the middle. Then I folded the fence over the log so that half is down on the ground and the other half is on top, but both ends end at the same point. I don't know if this is needed or not, but I had lots of fence and it seemed like a good idea at the time.
The chain is wraped around the ends and bolted together. I put a few lag bolts through the chain, and into the log, to hold it in place. I then figured out the middle of the chain and created a small loop by putting another bolt through two links. Then I just put the loop over a 2inch ball on my tow bar in back of my tractor. Quick and simple.
The results really are amazing!!
