I have enjoyed using the imitation Gannon very much and it works well. I have smoothed the road in front of our church and my driveway, I smoothed the parking area at church and dug a sand pit in the back property. I have used the scarifiers to pull out old curbing and a thin poured sidewalk. I have a couple of things that I would change if I were redoing it today. 1) I found that I would get hung up with the scarifiers because I could not lift the box any higher. If I had put my pivot point a few inches further back I would have gained that much more in clearance. 2)I made the draft arms of the box (the arms that go from the square tube back to the pivot point.) out of 10
mm (3/8 ") material, and I wish that it were thicker, min of 12
mm. 3) I made my pivot point with a piece of pipe inside a piece of pipe with a back up 24mm bolt. I wish that I had used larger pipe for the pivot. I have not broken anything and I have not used it gently. So it is a success from my stand point, although it is really more blade than my traction can pull in our sand. I just run out of traction before I get the blade full or even nearly full. I believe that it could handle a 30 to 50
hp tractor.
I have done some exploratory surgery into the piles in the back, but have not fully leveled things out. I did not find anything too surprising; broken bricks, asbestos tiles, and a few pieces of rusty somethings that went into my metal recycle pile.
