In the past I have welded on Hard Facing welding rod, same thing they weld on Scraper and Dozer blades, lasts for years on an ATV blade.
Exactly. 4" or less new snow doesn't get plowed. It gets driven on. I keep the plow feet at full extension ... just take the snow down to 'just drive on it' depth and save wear and tear on both the plow and the driveway, and for me, reduce the chances of hitting a bad root, rock, or hard block of ice ... and I still bust a shear pin now and then - good thing they're two-ended and you can just flip it over and use it again ... takes 5 minutes!My drive is around 700 foot or so. I don't need it to be cleaned down to the gravel, just need to be able to get in and out. I drop my plow to the ground, lift it a couple inches and start plowing. Leaving a couple inches of snow is not a problem, especially once it gets driven on a couple times.
