In my mind you don't get enough snow to warrant a blower.
I do around a mile of private road & drive, all gravel.
The most heard complaint about plowing gravel is getting it into the grass.
I tried plow shoes, they just dug into the dirt as the ground isn't usually frozen the first couple and maybe the last couple times I have to plow.
PVC pipe was suggested, tried, it broke in cold weather.
Steel pipe is really hard to cut lengthwise and harder to attach.
Ended up using angle iron bolted to the cutting edge.
(In pic., bolted in place of cutting edge because holes were already there.)
Easy to attach & take off.
I can even plow paths in the yard with NO damage come spring.
2" x 1/8th" seems to be enough.
Works as well on front or back blades.
I even strap one on my york rake & use that to plow surprisingly well.
