Ewest, the back's not in good shape!! It wasn't in good shape before I started. I used a T-200 Bobcat to haul the stone and tried to place it as best as I could. When you're dealing with rip - rap you still have to hand work some of it. My Grandson was a big help in doing the hardest part of the back work. The # 4 wasn't too bad, I was able to place most of it where I wanted it with the Bobcat, then hand rake it to knock down the high spots. I just hope it stops my erosion problems and filters out the mulched up debris that runs off into the pond.I will send some pics as soon as I take them and can figure out how to send them.
