Guys, here are some pics I took of my setup including Edge Tamer. Lot's of peace of mind with them on there. Obviously a snow pusher is superior, but I think they are apples to oranges as one is $80 vs $1,000. The Edge Tamer skids very nicely over anything. I have about 15ft of belgium block striping at the end of my driveway apron. This was NOT good for my bucket edge. So the Edge Tamers are clutch even for just this portion.
As you can see in one picture, I can fit my finger under the edge of the blade. So perhaps between .5in and .75in gap there. The rear blade takes care of the rest, however. After practicing with this setup and I happy with the capabilities and money spent. I only did last winter and most of this one to realize I cannot plow with a naked bucket edge for even one more day. I cringe just thinking about it.
