I wanted to let you know that I run a YM 1510D with a 50" Farmking 3 point blower. I typically run it at 770 on the
pto. In light fluffy snow I run the thing in 2nd range to feed enough snow in it to make a nice roostertail. I've never run out of power with my little 18 horse Yanmar. The only problem I've ever had is with drifted snow when it packs real hard, I'll have to use the loader to break off chunks to keep the blower from riding up over the drifts. If they're not packed in hard enough to drive on I can push my blower through snow over 4 feet deep using low gear. I get snow falling over the top of the blower as I undercut the drifts. I can actually move more snow quicker with this little outfit than I could with an 1155 Massey with a 7 foot bucket. This thing is slick & maneuverable.
I bought my blower 3 years ago new from a dealer for 1900$
