BX2750 snowblower specs

[rugs]

Bitseeker--

Honda's tracked walkbehind blowers *are* great machines. Tip speed for Kubota's BX2750 blower is ~70 ft/sec.

It snowed yesterday so BX2750 on the BX23 got its first use. This snow was heavy and wet. The BX2750 throws almost as far as the Honda HS1132. It moves about twice as much snow per time spent. It also has plenty of down force so it does not try to ride up over drifts. It clears the roadside berm, left by the County Plow with no problem. The skids don’t really work, in “float” to keep it out of the gravel on the driveway. Has anyone here made up a quick adjust set of big caster wheels or some other fix to handle gravel driveways. The skids work fine on pavement. The Kubota rotator and deflector work fine, but the rotator is very slow, so it’s more efficient to back up quite a way and take a second cut, rather than turning around and changing the chute rotation. I sheared a couple of auger pins on what seemed to be just excess load (no rocks). Is that normal? Also, is it normal to have to drive the piece of the pin left in the shaft?

bitseeker,

I agree the BX2750 works great on heavy, wet snow. As for the skids I have a lot of gravel and very little paved so I setup for gravel and use the float. Works best if I let the ground freeze first. I end up having to scrape off the paved areas. I thought about making a 3pt "squeegee" for the paved areas but haven't bothered yet. I built my own rotator and deflector controls. As some others have here using an old car door power window motor. I tried a windshield wiper motor but it was too fast /forums/images/graemlins/shocked.gif I believe Kubota's unit is along those lines. You may be able to swap out to a faster unit. As for the auger pins they should shear for rock jams but not snow load. Is it possible one is getting a jam and they dropping it as the other pushes snow back across (backfeeding the sheared unit)? Are you using the Kubota shear pins that are turned down or a grade 2 substitute? It isn't unusual for the sheared half to be left in the shaft but I often see this with softer grade 2 pins that tend to shear and mash rather than harder units that break cleanly, thus the reason I was asking.

Enjoy your tractor and be safe,
Michael

Hi Michael,

Unfortunately, I can't wait for the surface to freeze permanently, as it thaws here throughout the winter. Lots of snow, but not continuous below-freezing weather. I think this winter the road has not frozen for more than a few days in a row (global warming?).

I planned to build my own hydraulic rotator and deflector controls based on ideas posted here, but when the Kubota electric units became available, my recollection ot my LONG list of unfinished projects took over. The Kubota unit looks like a car door power window motor. When I got to use the blower, I was really glad I had ordered the Kubota units, even though the rotator is slow. I am working on an enclosure, and by next winter when its done , the inside control will be great.

I am using the turned-down Kubota shear pins. I am considering changing the system to be like the impeller's two-plate and a conventional bolt. When sheared, the bolt-halves would be gone, and you could see the alignment and be back in business in a minute.

Thanks for your help and ideas.
