Thanks for the kind words and advice 4shorts. It might seem odd to someone to modify something you just made without trying out. But in this case your explanation made a lot of sense to do so. And just in time. One week ago today we got our first snowfall of the season here in southeast Michigan. And in my location we got 12 inches of wet snow. I couldn't believe how well this new plow setup worked; a night and day difference from my old plow which was much lighter. I also made another change from past seasons. I needed new front tires so I went wider from 8.5s to 10.5s and I got them loaded with Rim Guard. There was no tendency I could feel of the front of the tractor being pushed to the other side with the blade at full angle. I don't have a cross over valve and had no problem. I know about the skids you added to your loader arms and with the last plow I had I made a couple of rollers out of 1 1/2 inch galvanized pipe that I welded on the bottom of my plow frame crossover tube (which was just in front of the loader arms) which prevented the arms from touching the ground. I'm not sure I need something like that here because this driveway is asphalt (my old house was gravel) and I set the mount up so with the plow at 90 degrees vertically the cutting edge is just touching and the arms are a ways up. I also do one neighbors driveway which is all cement. This gave me an unexpected opportunity to have the bottom edge trip, which is much better than having the whole plow trip forward and flip back. All snow plows should be made like that. I believe you made a mod to prevent snow from flipping back, but this type of plow negates that. Happy plowing; I can't wait for the next snowfall.
We all have our opinions and preferences on blade types. I'm not a cutting edge trip fan. The full blade tripping absorbs much more force but that's just my opinion. I do like the arctic poly skin on mine. I've had it since 1994 and nothing sticks to it especially wet snow. Before I had this blade I had a regular steel blade and had to beat the wet sticking snow off the blade every three or four pushes. Enjoy your winter. There should be plenty of it ahead.
