Snowblower: Width vs PTO hp

[Klorinth]

_________________________________________________________________
EDIT: All this mess goes back to the cross auger(s) as the manufacturers are in no hurry to offer solid cross augers as standard equipment OR as an option except for the one or two dual auger models by Pronovost using a solid auger on the bottom ribbon/auger.
If they implemented a solid cross auger with narrow flighting the snow caster would work wonders and cast the snow a long distance

Can you explain that further?
What do you mean by "solid", and how could that help the OPer in selecting a blower?
I get the impression that it would control the flow of the snow better, but I can't quite see how. Would this make the difference between buying a 72" vs 84"?

Do you have a picture maybe?

I have a JD3320 with 33hp. Living in NW Iowa I have had no troubles with my 85" chief snow blower. This thing will eat anything I feed it ( including one of the kid's toys that happened to get left in the yard ) still picking up plastic ......

Leonz, your explanation was well said. The HST is perfect for jobs such as snow casting, where you have to vary the ground speed to maintain a constant load on the PTO.

BTW, you would lose the wager on where the salt comes from. It used to come from Pugwash, but around here it now comes as a by-product of the potash mine in Penobsquis, N.B. I am about 60 miles northwest of Pugwash and 35 miles northeast of Penobsquis.

Aw, Leonz, planting mums! I just finished cleaning up and tilling the vegetable garden on Friday, which is the latest I've ever done it, what with the mild fall we've had here so far. But that's about to change, based on the latest weather forecast! Hope you get 'er done, sir. All the best! :thumbsup:

I wonder if thier potash is like everyone elses with the Halite salt bed seam on top of the Potash seam? The folks at Irish Salt have a thick bed of potash they are mining below the salt bed that they are mining as well under the Irish Sea.


Herringchoker, how far are you from the new deep soft coal mine that was recently opened? Are they mining at the five mile depth near where the older workings were?

Sure,

The Schmidt picture I have uploaded shows a single stage unit with
a gathering wing but the theory of operation is the same as the auger may
be used to operate that fast feeding the impeller but some experimenting would be needed to obtain the proper speeds for the snow caster auger to feed the impeller.





If you look in YouTube - Broadcast Yourself. for european snow casters you will eventually find snow clearers used for highways and there are a herd of them built and sold for Mercedes Unimogs which are single stage and the casting distance is huge.

The snow casting drum would not have to rotate that fast with a two stage unit but the casting distance would be just as far or further.




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.

I'm not sure and I stand to be corrected, but I think the salt seam is above the potash.

There's been some talk about re-opening the deep mines on Cape Breton Island (about 300 road miles east of here), but as far as I know that's all it is...talk. Those shafts are out under the Atlantic Ocean. There were also very deep coal mines at Springhill, N.S. (near the Pugwash salt mine) but the big mines closed after the disasters in 1956 and 1958.

That was definately different. The only thing i wonder is what happens if you make a second pass, does the snow cover the first pass?

You need to upgrade to the deluxe model with movable shutes to take care of that problem :laughing:

Herringchoker,

You have answered the question I was about to ask... What is the effect of having an HST.

Seems to me that the infinite control of speed should allow a machine to handle more snow or a larger blower then a gear drive.

Am I wrong in my thinking?

If it is true that the HST can handle more in this case then the gear transmisson, then how much and how should you be running the tractor to ensure that it can handle it?

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.
As I stated in my original post, the snow throughput , from continuity, equals the snow depth x the width of the snow blower x the speed of travel. With a geared transmission you if you set the blowers speed to rated pto speed, the speed of travel is fixed by the gear ratio. In an HST, you can tailor the speed of travel (within some limits) at constant engine speed. So it allows you to lower the through put through a drift , for example, by only altering the tractors cround speed and keeping the blower at rated pto speed.

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