I'm glad it is working for you. I looked at those prior to purchasing my Farm King. I ended up with what I did, because it is local dealer and I know how well the build is base on the one we have at the office. Virtually no/little maintenance and sits outside summer long. Not our firms equipment, belongs to the property Owner who takes care of maintenance.
We have an 850 JD with a 60" Farm King 2 stage blower. It is a gear tractor, but in snow more than 8" it is all the tractor can handle if you want any speed what so ever. The low side of reverse is so slow it almost doesn't move. That speed is too fast for drifts. According to tractor data the JD has about 20 hp at rated PTO speed. Beats my 17.
My bx2350 has the same blower only in a 50" and it does a good job with 16" drifts without having to crawl or stop.
