I put a pipe on my edge. Welded tabs on and then just bolt it to the edge. Got to use it for the first time last week and I was real happy with it. I have around 1100 feet of driveway and 1/3 of it is hill. My hill also has 3 swales to divert water off the drive and into the ditch. The drive is 12' wider and wider is some areas. The pipe worked great but I still have to control the down pressure and work the control on the swales. Hoped I could just let it float but that pushed to many stones. My system is to angle the plow and only clear the center 8' or 9'. That way any stones just stay on the edge of the drive and not in the lawn. I did not move many stones but some did come up. I don't like the pack down the first snow system because I am on a north slope and I have had as much as 4'' of solid ice using that system. If your drive is flat then no problem.
I also have another invention. I have a stone rake for my garden tractor. I put a thick piece of rubber on the bottom edge.. Then angle it and pull it up the hill to clear as much snow as possible. That gets me down to the bare stones without moving many stones. That really helps to keep the ice off the hill. In fact if we only have 1-2 inches the rake is all I use. It is very fast operation. My problem is I must keep all snow off the hill or chop ice. I don't like chopping ice. It is not a fun afternoon.
Does anybody wax their snow plow? I used to do it all the time with the snow blowers.
Guys- I don't get the pipe thing. As Don W noted, you run the risk of ending up with ice. I have an HDPE edge on my 7'Fisher- problem I have with that is it will not "cut" hardpacked snow- it's a "catch 22" situation-either you move some stone or you leave enough that at some point, depending on snow/rain cycles,you end up with a glazed surface.
Then you are into the sanding thing-by the way, for what its worth, best way I found to do that is put the bucket back on and pile sand in each end of bucket. I then drive at a good clip and "flick" the bucket-leaves sand where you need it -in the tire paths.
