Any input on these?? Looks like they might move a bit more snow @ 1,100 RPM VS a 540 RPM pto powered blower.....

Cost will be significant considering its hydraulic drive (think 7-10K if I was to guess) but even more concerning is the fan section. The fan appears to be almost entirely enclosed and the augers feed into small ports on each side. To me, thats a recipe for extreme clogging in anything other than dry snow.
It would be a nightmare to unclog if it packed up with all those chains and sprockets in the centre, plus all the guarding.
Also the augers have to feed all the snow into the fan and you cant rely on a "ramming effect" to keep the fan full like you can on a conventional blower.
Using the tractors hyd as a resivoir is also a bad idea without external cooling. That's blower would be high flow at 100% duty. It should have an external pto powered powerpack with its own tank.
I think there is a reason that you dont see too many blowers with that style fan. id like to see it in deep, wet, heavy snow, not a few inches of light stuff.

I would say both sides together would have as much or more of an opening than a 2 stage. The 1,100 RPM fan speed would help the clogging issue even on wet stuff i would think.....

The snow is getting pushed into that narrow cavity from augers on both sides, its not so much the total opening size, its the two small openings vs. a single, large, open fan of the same total diameter.
Hydro or not, small tractors have a limited oil reserve. This blower isnt like running a splitter off the aux hydraulics, its much higher flow and will generate considerable heat in the small resivoir. Minimum GPM for that model is 14 GPM. The rule of thumb for hyd resivoir sizing is 3:1, so @14GPM you should have 42gallons of tank. I dont know what the capacity of the 3037 is however, and you can cheat that 3:1 ratio a bit. Still, I wouldnt go with it without a external resivoir and a closed, self contained system. Would you even get 1000RPM under any real load @ 14gpm? I dont know and they dont publish much info on the Sheyenne website.

i would bet that in the video showing the hookup to the kubota tractor shows
there is a pto powered pump system on the 3ph, seeing the large filter mounted up on
the boom near the hydraulic couplers.

I too was wondering where a CUT would get that kind of hyd volume. A PTO pump on the back is a pain.
Nice blower though. Nice that people are trying to come up with new ideas.
If debris or a stone got into that thing at those speeds, it would become a bad day in a hurry.

The Berta Snow casters from Italy are built using 2 solid cross augers directing all the snow to the center solid auger section which pushes the snow into the impeller at a metered rate to prevent plugging and jamming.
The center section is split slightly to allow the gearbox to rotate the solid cross augers.
It is not what I would have done as its simpler to run a high speed chain drive to the cross auger from
a right angle gearbox using a larger diameter toothed sprocket rotating a smaller one to operate the cross auger as a single stage unit as is done with flail mowers and tillers the world over.
The "Key" to all this is having the serrations in the auger flighting to cut the snow up in smaller chunks.
If you look at the Yamaha walk behinds sold in Canada and now in Europe the cross augers are open and use serrations and a much higher speed impeller paddle- just think how much farther the snow would be shot out of the impeller housing if they used an impeller kit!!!!!!!!!!!!!!!!!!!
But they move a lot of snow in the alps so............ If anyone is interested you can contact Joel at Earthtools to get a quote.
I am still looking for the picture of the twin disc single stage snow caster I saw a while back mounted on a 4 wheel drive mule.I am mad at myself as I cannot remember where I saw it!!!!
It is modeled after the Beilhack railway snow clearer only in a much smaller size and its operated
from the rear PTO.
