Snowblowing or Snowthrowing?

Discussion in 'Commercial Snow Removal' started by Chuck Smith, Sep 14, 2003.

    I didn't want to take the original thread this discussion started in off topic, so I started a new thread.

    Where to start?

    Lets see, a single stage unit uses an auger to route snow to the center of the auger that has a flat section, or paddle, which "throws" the snow out a chute.

    A two stage unit has a set of two augers, that route snow to the center of the auger housing where it is sucked into the impeller housing by the impeller which in turn "blows" it out the chute.

    An impeller is basically a fan. The difference is that the vanes are not curved, because the impellers on snowblowers are designed to move a solid (snow) not a gas (air). If you were to engage the auger/impeller drive on a two stage unit, and placed your hand over the discharge chute, you would feel the air blowing out. Not at the same velocity, or cfm as a leaf blower, but, that is due to design. Leaf blowers are designed to move a high cfm, thus the curve of the impeller blades on a leaf blower.

    If you look into the front of say an 8hp walk behind leaf blower, you will see the impeller (fan). It does not look like the ceiling fan in your house, or the radiator fan in your truck, because it is actually more of an impeller, not a fan. Some owner's manuals call it a fan, and some an impeller.

    If you were to replace the front cover, and add a different discharge chute, you could use it as a leaf loader, to put leaves in a truck. Same impeller. In that case, the impeller is moving a solid (leaves) and not just a gas (air). The vanes create a suction, that draws the solid into the vanes, which in turn "blow" the solid up the discharge chute.

    Main Entry: [1]fan
    Pronunciation: 'fan
    Function: noun
    Etymology: Middle English, from Old English fann, from Latin vannus —more at WINNOW
    Date: before 12th century
    1 : any of various devices for winnowing grain
    2 : an instrument for producing a current of air: as a : a device for cooling the person that is usually shaped like a segment of a circle and is composed of material (as feathers or paper) mounted on thin rods or slats moving about a pivot so that the device may be closed compactly when not in use b : a device that consists of a series of vanes radiating from a hub rotated on its axle by a motor

    Sounds like an impeller to me.

    Main Entry: im·pel·ler
    Variant(s): also im.pel.lor /im-'pe-l&r/
    Function: noun
    Date: 1685
    1 : one that impels
    2 a : a rotor located in a conduit to impart motion to a fluid

    Impellers were designed initially to move fluids. All plow pumps have an impeller inside, that moves the fluid, and creates pressure.

    In a nutshell, an impeller can move a solid, a liquid, or a gas, depending on design. The size of the discharge orfice will regulate the pressure at which it leaves the impeller housing or pump body.

    IMO a unit with an auger only (single stage) is a snow thrower. A unit with an impeller (two stage) is a snowblower.

    I can understand why the engineers that invented / designed / manufactured these two different types of units assigned the names that they did.

    WE have always called it a snowblower,does it make a difference what it's called as long as it works and clears snow.But I guess technically it does throw the snow,With the wind blowing it ;)

    Okay this is how I see it.When i start my Leave Blower it starts blowing air out of it and moving objects that are light around.when I start my Sno Thrower and put it in gear and engage the auger it is collecting up what is in its path and throwing it out the chute.My Snow Thrower Ariens even calls it's units Sno- Thro.

    While the snow is being thrown and if wind starts coming it tends to blow around the snow making a blizzard like appearance.So why don't we all just settle on its a machine that can simulate a small blizzard.

    Oh by the way Chuck I am not trying to argue with you, then again you are most likely smart enough to know that.I originally wrote snow throwing not snow blowing as a satire point of view.It's just there are some people here that just don't understand certain postings because their mind cannot distinguish interpretations too well.

    Bottom line call it what you want, snow blower , snow thrower I can care less.As long as the thing starts and does its job then everyone's happy right????

    Well at least I learned that there are some people here that cannot process information correctly and to be more in depth when posting something.

    Anyway Chuck you seem to have involved yourself very deeply into this topic with your detailed point of view.Thanks for the insight and contributing your 2 cents worth.

    Ill call mine a Gas powered, Portable, wheeled, snow removing machine. That way no one will question my blowing or throwing of snow.

    Snow blower or snow thrower who really cares? Everyone will agree that as long as it will remove snow then it can be called anything. Ive always called them snow blowers so sue me. there better then snow shovels and not as good as snowplows.

    dont matter to me, but items listed as a "snowblower" on e-bay get more hits then "snowthrower"

    I would have to agree with you snowjoker, my 566 will throw snow from my driveway up over my Ranch and into the backyard!! Jay will be amazed at how far that Gravely will throw snow with the engine just at an idle.

    My single stage, tractor mounted blower does indeed move air from the chute. Then again, the characteristics of the expelled snow is more that of being thrown and not blown. I believe the factory paperwork on the attachment does label it as a "snowthrower".
