I saw were somebody put a pvc pipe on their blade, so that what not pick up the gravel on their driveway.
I had a piece of 1-1/2" pvc pipe lying around , so I cut it to length of the blade and cut a slot in the pipe to fit on the blade edge.
I drilled a couple holes and screwed it to a 2x4, so the I could cut the slot on my table saw.
that way it make a straight cut.
it fits on the blade tight.
I tried it on the driveway, had to go a little slower because it started to bounce.
I did a good job on the driveway, then I tried the sidewalk. I did a good job there too.
it was sliding over the grass next to the driveway ans sidewalk.
It did not tear up the grass like the steel blade was doing in the past.
it is a keeper. will keep it for this winter.
I wish I had it last fall when I used the blade to push walnuts into a pile.
It tore up the grass. next year I will use it to push the walnuts into a pile and will not be yelled it for tearing up the grass in the yard.
