I agree in a little time the scratches will fade. Ive been plowing snow for yrs, more then i care to admit,for twshp, and personal contracts.You guys crack me up worrying about things like this, a plow is no good if it doesnt clean the surface you are plowing. I have a fairly long gravel drive way , my brother does also, the last thing we worry about is plowing the gravel. the plow marks on a hard surface are nothing.If you pay attention you can do a fairly good job easily The customers I plow for want it CLEAN or as much as possible. You cant get it clean with the plow edge covered or elevated.If you run chains and spin out you do more damage the the plow edge. just my 0.02cts.
