I got a start on my rotary snow plow. I am basing it on the UP 900081 plow. The 900082 is still operational and in their roundhouse in Cheyenne, it is so shiny it is hard to get a picture of it! Here is 81 in St Louis museum.
It is 52’ long so the Aristo B unit works fine for it’s chassis. I will use it’s power trucks also. I got it on ebay, a guy had started a rotary but did not get far. I did use his blade he had in the box. The B unit was new, $35!
I used the blade that came with it. The shroud is a 4" plumbing cap that I turned down a bit on the lathe so that it would fit inside. I built up around it with 1/8" plastic.
I am using a old 12 volt drill, I plan to use a 18 volt battery, Ron Senek did that in his rotary to make it spin faster, he said it worked great. I added some re-infocement angles that are glued/screwed. Just screwed to the frame though. I am ging to put aluminum angle along the top of the frame to strengthen it and widen the body some, if you look at the above photos you can see it hangs over some.
