Snow Attachments Snow PUMP

[fitterski]

To double the mass flow of snow and throw it 4X as far will require 8X as much power. In other words doubling the speed of the blower pump will require 8X the power. If you want to advance through the snow twice as fast but throw the snow twice as far the required power will be 4X as large.

are the only ones that I know of who actually state the throw distance and the tons/minute. I want those throws but at a lesser volume. I haven't yet been able to put 'numbers' on 7-foot swath, 8 inches-deep, 10km/hr, dry/wet, x-feet-up ...etc. but experience has also confirmed the basic physics i.e. that an obscene power increase is required. I'd be wasting my time even considering anything below 180hp and since the only difference between 180 & 350 is weight and fuel consumption all I really have to solve is the weight limitation as it applies to 4-5 different dev. scenarios.

Having a small block chevy talking to you at full bore on the back of a Ford f250 pickup blowing snow 100 feet in the air? That would be you-tube worthy.

It brought a smile to my face just bringing it up!

They ARE on the list of candidates as part of a possibly hydraulic solution mostly because they start easy in cold weather and because a hydraulic pump doesn't care much about the rpm where the power is available. On the current rig any mechanical reduction beyond the present 2.5:1 would be too problematic without a weight increase and no weight increase at all is available. All aluminum versions weigh-in at less than 500 lbs which could be interesting but I haven't kept up to date about gas engines at all (since my Corvette/Mustang days). I pay 500-1000 for engines good enough to rebuild with just a standard kit & I have never built an aluminum engine.

I'm not following you with the reduction. A pto gear box isn't that expensive if you can find one setup the right way. The nice thing about hydraulic would be the flexibility of the mounting location for your power unit.

This should become a winter motorsport right up there with pulling and things. I sugested that much in the original video but it isn't happening. A whole new industry could form around it AND increase the demand for non-digital (sport/farm/industry) engines which seem to be about to go extinct.

That was for the existing mechanical solution on the existing platform where I just don't have room for a bigger pulley than the one already on there for the 2.5:1 reduction right off the flywheel. In any hydraulic solution, and yes flexibility would be its only excu$e, I would need mechanical reduction only for/in the auger chain-drive

Do you not have room to add an additional shaft and therefore another belt pulley reduction in a different direction. Think one leg of a triangle vs two

Pronosvost lists their back hoe loader bucket mounted self contained snow blowers capacity in tons per hour or at least they did last year.


My friend you have forgotten the magic of an age old invention, the flywheel.

A small weight flywheel supported by a pair of pillow block bearings attached to
the 540 rpm gearbox of your Frankenstein snowblower will surprise you no end
as that 4 cylinder Duetz engine will barely grunt when the flywheel reaches the 540 RPM
maximum of the gearbox.

The same would apply to a pronovost TRD800 with the rotating impeller drum if a
flywheel was used.

Would a flywheel help in a long sustained full load blowing event?

If you look at the u-tube video cited in my sig @ around 1:35 & 2:15 you'll see it, it's solid steel and weighs like a ton but I had to use it even though the rig cannot take another ounce of fat. As for stalling the 4-holer fear no evil, in 8 years I have become an expert at it :laughing::laughing:

i'd have to move the engine farther back by by about one cylinder, same as i would swapping in a 5-holer, but it's too tight. I've already touched the alternator pulley once.

Those Schulte blowers are BTW very well made. I looked at them in 2008 already, also tried to sniff out if they'd sell me a ready made fan but never got a reply.
