Your 226 has about ~12hp capability for hydraulic power. Including moving the tractor. I'd recommend finding a way to make a belt drive work, or a belt drive to shaft drive adapter depending on how that blower was driven originally. Then you have the full 16hp.

 

Thank you for your insight, it’s truly appreciated!

 

Ben, don't quote me on this but, from memory, The main impeller doesn't turn that fast on dual stages, I'd hazard a guess at 1000 rpm? The secondary impeller, that thing is likely turning at 3600 RPM or so.

Can you post pictures of where you'd plan mounting the motor? Is it a chain drive from there to the main impeller, which also drives the secondary? You will love a dual stage,,

 

I’ll attach some pictures. The large pulley on top spins 2.8x for every turn of the impeller. I’ll have to work my way back to the tractor PTO speed. Gotta figure that out.

Sitting on the tractor I’d place the engine on the right side of the chute and tuck it low as possible. Think a kohler magnum twin would throw nice. I’d still like to try hydraulically first.

 

Well, I tried AI and this is what it came back with.
The rotational speed of a dual stage snow thrower varies depending on the model and its settings. For instance, the Greenworks 82V 24 IN Dual Stage Snow Thrower offers five speed settings for its auger and impeller, with auger speeds ranging from 80 to 120 RPM and impeller speeds ranging from 800 to 1200 RPM.

One could hazard a guess, Typically, motor driven sheaves are roughly around 4". That pulley in the picture looks like 6"? So, at wot, 3600 off the motor should be spinning that pulley shaft (70%) at about 2500 rpm? 2500/ 2.5 and that would tend to show that little sprocket at the bottom (secondary impeller) turning at about about 936 RPM. (which happens to work out close to what AI said)

This motor turns at 770 RPM, it's close,, but it doesn't say how many /gals/min but I think, it exceeds what your pump puts out,

Seeing how similar that belt drive system is to the belt drive already used on a Case/Ingersoll snowblower... I'd be even more inclined to run it belt drive. Then you can just buy a different size drive pulley to change RPM as desired. And it would already solve your "attaching to tractor" problems, the "how do I lift this thing" problems, and the "how do I tension the belt" problems.

Get an old junk snowcaster and take the mule drive off of it, build a bracket to attach from the mounting points on the 2 stage to the pivot points on the mule drive, bend those pulleys mounts on the bottom of the Kubota blower slightly inwards so the belts point towards the Case/Ingersoll pulleys, swap the flat pulley on the Case/Ingersoll mule drive for a V pulley so the orientation is correct, voila, she bolts right up.

No need to deal with hydraulic power restrictions or any of the other mounting challenges.

(Make sure it's all spinning the right direction first haha, otherwise you might have to get slightly creative with the belt routing.)

 

Agreed. I think the bracket to the Kubota caster could be the same one from the Case. Just cut it free from the housing and remove the horizontal drive shaft and sheave. If width allows it could be welded to the Kubota housing . It would solve the lifting issues.

 

Don't underestimate the present weight and extra weight moving the blower farther out AND adding an engine. Our Cases are 2 wheel drive and become quite useless once most of the weight is removed from it's hind legs.

Definitely a good point on the weight of the blower but I think by "motor" he meant hydraulic motor, not a pony engine.

 

Here is a MTD snowblower adapted to a CASE tractor. The nice thing about the CASE tractors is the engine rotation is correct for MTD style snowblowers whereas the Ingersoll 4 digit tractors engine rotation is reversed. These pictures may give you some build ideas. I saved these pictures from a craigslist add in Maine a few years back. I have a few more pictures of the build but I'll post what shows the snowblower.

 

These pictures may also give you some ideas.

 

 

I have more MTD style snowblower lift pictures I can post if you want me to but I think I hijacked your build thread enough for today.
