Snowblower: Width vs PTO hp

[leonz]

I rounded higher for simplicitys sake. Are you in the Lignite coal portion of the Basin Jerry or near the Wyodak Coal Seam portion?

Your 147 lb per sec must be a typo then.

I live in the Mission Valley .

I thought I scribbled 147 pounds per the seven foot width
of the snow caster at a one foot depth of snow fall. Whoopsie!!!!

I will go back and fix my whoopsie.


EDIT: I cannot go back and fix my WHOOPSIE, it should be 147 pounds per 7 square feet times 3 to equal 441 pounds per second at three miles per hour of travel speed.

A solid auger is nothing more than a grain auger of sorts with
narrow flighting which is the distance between each section
of ribbon on an auger.


The key is having a large diameter drum that the ribbbon is welded
to which limits the amount of snow that can be metered to the impeller
with zero flooding and jamming.

A larger diameter drum and ribbon would be very easy to use and operate
with two stage or single stage rear mounted snow blowers.

If the flights were 10-15 degrees apart and 4 inches deep the snow removal
with a two stage or single stage snow caster would become a zero issue, but the snow caster would cost a bit more to build and purchase.

Now that makes sense.

So a guy would have to get a good sized pipe and find a way to attach the flights properly. An easy modification...right? Way beyond my skills, but an interesting idea.

Sorry to but in but the HST doesn't allow you to handle more snow. it allows you to match the blower's capacity to the ammount of snowfall by having a variable ground speed at constant pto speed.

Thank you Jerry.
I thought about it after I had posted it, and realized I had written something wrong. Definitely not more.

The ribbons are cold rolled in most cases and welded on the hollow drums used for the single stage snow casters and grain augers.


It is something that is easily done by purchasing pre- assembled conveyor pulleys and bending and winding the strap iron to create the ribbon then weld it to the pulley. The bearings would have to be 2 row roller bearings to handle the weight but they can be mounted simply on the exterior of the snow caster.

You have to convert 3 mph to feet per second to get the units correct. It's 1 ft x 7ft x 4.4ft/sec x 21 lb/cu ft =646.8 lb/sec.

Im kinda confused here with these calculations. Everytime i move snow it varies as to whether its dry pack, moist pack or just plain WET snow pack. How can there be one set #/sec rating for all these different kinds of snow conditions?

For me...it's over thinking. What i know is I have a 75hp tractor(64hp on the pto) and a 7 1/2 ft blower is big enough. My tractor has a 16x16 tranny. If i had a 45hp tractor with the same blower, it's not gonna work. Even if it's a hydro tranny. But keep in mind, I don't blow snow unless the storm is over or someone needs to get in or out.

There isn't. LeonZ stated that dry snow weighs ~21 lbs per cu ft and if it's wet, than the density can double. if the density doubles then the weight flow doubles all other things being equal. if the weight flow doubles the work doubles and so the power required to blow the snow increases. if you're running at max power, you either have to reduce traveling speed, take a smaller cut, or both.
