Skid steer snow blower on tractor loader?

[ruffdog]

The point being made by the Messicks video is how much power is really made at the FEL lines. This 60hp tractor has 9.5gpm at 2800psi which amounts to only 15.5 hydraulic HP. They wanted to make the point that just because it fits on the tractor, it doesn't mean it will work.

The op isn’t planning on doing that. He knows the tractor hydraulics can’t do the job. He’s planning on building a pto pump setup.

The internal tractor hydraulics are probably never sufficient to drive hydraulic attachments like that, but the PTO mounted pump pack is how it is properly done. They discussed both but still made it seem like a PTO mounted pack was never a good idea. My point was simply that a properly sized system of that nature would be perfectly fine, and proven by the fact that they are manufactured and used regularly. I don't believe anyone here has suggested running off the tractor's internal pump.

They wont work on internal pump. My pto pump puts out at least twice the flow and 1,000 psi more than the tractor.

The Messick's video is good, and covers most of what people have said here...

1) Tractor hydraulics aren't powerful enough.

2) A properly sized PTO power pack can provide sufficient power

3) There is more power loss in a PTO hydraulic pack + drive motor than in a shaft drive

So my take is that there is no reason it can't be done and work well, provided everything is sized and engineered correctly.

Yes you can build a PTO power unit to drive a front mounted snow blower. Like you stated the components just need to be sized correctly.

what input speed are you looking at for the blower? 540 or 1000 RPM? No clue what skid steer operate at.

My toolcat has a rear 540 rpm pto that is hydraulic and the specs say it is 25 HP. Last winter I tried my 5 foot blower for the first time and it was in deep snow (2-3ft)(sleet) that was very heavy (like sand). I never stalled it and was surprised it did that good, even through plowed banks (4ft). With using specs and formulas, you should be able to size what you need.

I've been looking at the hydraulic specs for SS blowers, presuming that if I meet those specs I will get sufficient blower and auger speed for good operation. And I'm leaning towards the higher end of the specified flow rates because I know my PTO snow blower works much better at the highest speed I get get. But in a hydraulically driven blower, I don't know how the flow rates translate into blower or auger RPM.

I'm NOT planning to convert a PTO blower to a hydraulic motor, mostly because I want to keep my existing PTO unit operational until I've proven any hydraulic replacement.

Skid steers can have between 25-40 GPM AND 3,000 to 5,000 psi. They dont have pto systems, at least not that i have ever seen. My own rear power pack only produces 3,000 psi at 15 gpm. Thats all a 45 hp tractor pto could power.

the last skid steer i rented was 100 hp.

When you get close to the numbers you want, you will have to decide on a motor package on the blower. There may be some overlap on the specs so you can decide what displacement motor will better fit your needs. Do you want more grunt for drifts or farther throwing? A smaller motor normally runs hotter so you need better cooling.
