Why do blowers do better on a full load tham when half filled?

[Fluid]

What did I say that you disagree with?

A snow blower and a snow thrower are two different machines. A snow blower does not pack snow before it blows it out the chute. So I guess the packed word, unless your talking about a snow thrower. If you watch this video you can see that the auger fluffs the snow before the impeller blows it out of the chute. https://www.youtube.com/watch?v=jX14jLoHjmI

I don't know where you are getting your information, you are talking about a snow thrower or caster, snowblowers are whole different animal. Are you just talking about a caster? There is a two stage snow blower and then there is a single stage snow thrower. The auger on a snowthrower collects and packs the snow a little as it moves it toward the chute and throws the snow out of the chute. The auger on a snowblower breaks up and fluffs the snow before it enters the impeller which blows the snow out of the chute. You will never see a snowthrower do this.

UH HUH, the self propelled Italian railway single stage railway snow clearer using twin snow clearing discs with four snow scoops on each disc in the picture is clearing snow that was plowed in the center of the railline by a plow train with a gathering plow mounted on the rear car of the plow train in the Alps.


My experience and information comes from dealing with 47 years of New York winters.
using a 12 horse single stage IHC cub cadet with rear chains, walk behind two stage snow casters,
Toro Snow Pups from 1968 to today, tractor mounted plows on IHC cub lowboys, 1969 Simplicity
tractors with single stage snow casters, snow plows mounted on Wheel Horse tractors with rear
chains and single stage snow casters, Wheel Horse tractors with plows, The Plow on my 244 weights
more than the JDLA115 tractor itself.

The proper term is snow caster. The impeller on the currently offered machines would not and could not blow the snow it is encountering because the impeller contacts the snow and lifts it up and out the chute and spout OF ANY singe or two stage snow caster.

The snow is also too heavy for an impeller of this type to BLOW IT due to the speed and volume of air required and the pressure required to perform the same task.

Please look up railroad jet engine powered snowblowers to see what I am referring to.

What you have posted on your video is horsepower delivering horsepower to create torque to be delivered to
the cross augers and the imeller paddles to cast the snow away at a high rate per minute strictly in relation to
the prime movers (Tractor) speed forward and the depth of snow it encounters wherein the open design cross
augers are conveying the snow it is encountering to the center of the snow clearing attachment flooding the
impeller creating the appearance itis being blown out of the cute and spout(ITS NOT).

A high speed blower/jet engine would have no control over the snow it encounters and its creation of a wide
pattern of dispersal of the snow and ice it encounters.

The Russians have been mounting surplus jet engines on surplus tanks for years and using them to
clear streets as its easier than trying to plow them and its nothing new.

Thread pruned. Too many participants to send notices to. Come on fellas... its close to spring, snow's a melting, no need to fight about how a snow blower/thrower works. Please discuss it in peace instead of throwing/blowing insults. Thanks.

I,m sorry for you guys (mods) have to deal with this thread.

Has anyone done a study of what goes on?

Seems like a blower should blow air if it's not filled with snow...but we all observe, this is not the case. Chutes choke...etc..

What would be the physics?

First, blowers are generally considered two-stage, with an auger to break up the snow and direct it towards a center impeller, that blows it out the chute, while throwers are generally considered single stage, with a rotating drum that directs the snow straight up the chute, thus throwing it, not blowing it.

As to why either of them work better when filled than not filled, as other's have mentioned, the analogy of throwing a packed snowball VS a fluffy handfull is pretty good. With a single stage unit, you kind of have to find the sweet spot to keep the unit filled with snow so the snow that's entering is pushing out the snow that's leaving. It seems counter-intuitive that if the thing isn't throwing the snow very far you may have to increase forward speed to pack more into it, but that's pretty much what you have to do sometimes.

So you guys are just talking about snowthrowers, not snowblowers?

What about a snow caster?

It cannot be discussed in peace in the presence of adamant wrong "opinions". To ignore such is a disservice to knowledge.

NO. It throws the sno as it would a rock. The incidental air in the discharge is moving at the same speed as the snow or orher stuf that is in the discharge. The air does not impel.

But then you still post more:confused3:
