New to pushing snow.What's a good starting point to set plow at?I have a '49-52 plow set up. There are 5 holes on each side of plow.Mine has the pin through the second one up from the bottom on each side.The pin is in the middle hole on the one with the big spring holder underneath.I seem to be digging in.Also what is something I can put on the bottom of the blade for it to ride on so it skates on the driveway(dirt lane)?I don't weld.I always get such great ideas and feedback on this site.Thanks alot.
