one thing that helps is the snow not sticking to begin with, each fall before the snow starts to fly i will polish the backblade and bucket with an inexpensive car polish, if i end up plowing a lot sometimes i will reapply.
That's a really good idea. I'd bet just smearing Turtle Wax onto the plow blade would help a lot, even if you don't bother buffing it off. Application is even less work than the buffing.
This also got rid of the salt residue
This is a new problem for me. I bought a nice sparkling new Deere in 2019, and because it's only for personal use, I always figured the thing might still look damn near new when I sell it in 25 years with 2500 hours.
However, a friend had a single daughter move into a house just a half mile up the road from me, and he lives something like 40 minutes' drive away in good weather, probably an hour's drive on a snow day. So, to keep him from having to drive up here to shovel her out, I told him I'd plow her driveway whenever it snows. It really only takes me 10-15 minutes to drive the tractor up there at 10-20 mph, plow it, and drive back home.
But what I found on the first attempt last week, is that the mess of black salty slush on the road sprays all over the tractor, and in fact all over
me! Now, this tractor which I never had to hose down or wash in winter, must be either washed after each snow storm, or left to rust a bit. Also, I come home with the sleeves and shoulders of my Carhartt inuslated coveralls all covered in black road water.
I'll try just driving much slower next time, but if I find I need to keep speed down at 3 mph (i.e. "trail speed"), it'll turn that 1 mile round trip into 20 minutes drive time... plus the few minutes it takes to do the actual plowing. I'm always in a rush to get to work on snow days, after having spent time to plow my own (much larger) driveway, and clear the walks by hand.
