Back when I plowed I found that while it was nice to get some speed up and get the snow to fly over the edge and down the hill it was easier to just accept that every so often I just had to use my FEL to push the snow over the edge to keep the banks down. My '77 International truck has a 10' blade and weighs over 10klbs so it can move some snow but sooner or later the banks would start closing in no matter what I did. Now I have a front mounted blower and while slower it only takes one pass down then back up and I'm done and the snow is gone forever.
Thanks for joining the discussion and for your input. I can appreciate what you're saying because even the big highways trucks that look after out rural roads, eventually end up with banks that are too high to throw the snow over. Then they use a wing to push back the tops, which allows the front mounted plows to throw the snow again. I guess I will always need a blower but sure would like to reduce the number of times I need to use it. Maybe I won't mind using it when I get it converted to front mount. The stage I'm at now, the banks are about 30" high and I have used the blower to make the driveway as wide as possible. Now when I plow it just stacks up against these banks on both sides and there are some areas where the bank to bank distance is fairly narrow and it wouldn't take much snow plowing before I will need to blow again. Based on the long range forecast I may not have to blow again, if I'm lucky.
