Snowblower

[PILOON]

My blower has about a 16" 3 bladed 'fan' and at 550 RPM it barely shoots 8 ft.
Fortunately my CUT has 3 speed PTO and I use the 750 RPM for regular fresh snow blowing.
When in hard packed banks I do revert to the 550 to save shear bolts.
My 'take' is diameter= distance or perhaps better stated, blade tip speed=distance and blade surface=capacity.

Hence; larger diameter=better throw distance.

Surface/capacity would depend on PTO HP as well as travel or feed speed and hence a hydrostatic tranny is best suited for blowing with the manual tranny as last choice.

Curved blade would help 'toss' furthur, but is it worth the fabbing extra work?

Personally I believe that the best 'upgrade' a fellow could do is have a 'non stick' liner in the blower drum as well as a moulded plastic shute as that would eliminate the most frustrating blowing headache of all.
CLOGGED SHUTE FROM WET SNOW!

I long have wished to paint my snow shute with pickup truck liquid bedliner just to try that out.
Fitting my shute with plastic kids slide-a-boggin sheets has hepled tremendously but tends not to last all that long due to attachement difficulties but does prove the principal.

Jim I think that peace of steal you refer to is part of my mower deck mounting system. Yes the loader will detach as well as my bucket. As soon as I can I well post more pictures.

I have built a loader for my BX 1850 Kabota. Now I am planning to build a snowblower. I am not satisfied with the commercial snowbblowers. The fans run too fast, the vortex is hampered by the flat blades and they create a wall of air that impedes the intake. I propose to build my snowblower with a fan speed of 270 rpm, 8" fan depth, 24" fan diameter, 10" exhaust port, a 95* pitch, and overall width of 50". Will the backing plate impede the horizontal air intake I am trying to create?

Hi Garnet,

Nice looking loader, no doubt you can fab. Not sure I agree with you about the wall of air. As the fan paddles rotate and push the air ultimately out the chute it is replace by air at the front edge. There is no wall of air there, there's a suction there, just in like all centrifugal impeller pumps. Maybe there would be a wall of air if there was no discharge chute.

As are a fan speed goes, the more the merrier...up to the point where bearings are an issue as well as your speed to power curve goes.

I think that most run around 500 RPM for this reason. The large diameter fan is a plus, size of the cute opening is critical. Keep it as big as possible. Some engineers figured that a small chute would cause higher velocity and less clogging. Small chutes clog just fine and stink when it comes to throughput. No need to squeeze all that snow thought a small chute...just eats up HP.

Speaking of which, how much HP do you have to play with? I'd keep to no less than 3 hp per foot of auger. Keep in mind the losses of transmission and splitting of power off to drive the tractor.

For this reason and others I put an engine on my attachment, Frankenblower. YouTube - Frankenblower March 9 2009

Good luck with the project and remember, there are NO crackerjack prizes down the chute.
