husqvarna higher end snowblowers have a high speed impeller.Honda impellers rotate at a higher rpm compared to toro,ariens simplicity etc.Is this just a company decision ?Are there reasons why an Ariens or Simp dont set their rpms higher?

Read slowly AA.I know its hard for you,you're from the midwest yuk yuk(flyover country) lol.I said starting Jan 1.But now all bets r off.I do have the worlds greatest snowblower and u r a fool hehehe.And knee biter u r a douche.Dont be mad because Buckner blew it in 86.....

Lets hope for 2011, you can make some progress on that sophomoric behavior.

That says it all-The ability to throw great distances is not desirable where houses are set close together or in urban settings like New York City where the Sanitation Dept. will give you a Summons for blowing snow into the street.

 In addition you can't get something for nothing. If you adjust the size ratio of the pulley system to increase the rpm of the fan then under load you are going to need more HP to take advantage of the distance potential of the new pulley size. If they achieve a 30% increase with the same HP engine the unit must be over designed  to begin with. I wonder what happens when you hit the EOD with the high speed set up. If the available hp  is now being used to achieve high fan speed I don't think the end of driveway performance in plow packed conditions would be as good.

thanks marc for the explanation.I was asking a question but knee biter and AA had to start.Malachi crunch lol .yea ok knee biter you better run along,Happy Days reruns start in 1 hr...geez lol.....

At least you are ok that it is all in fun

Changing the auger drive pulley to a smaller diameter will increase rotation speed. The effect is the same as changing sprockets on a motorcycle. The larger the diameter sprocket on the rear wheel, the greater the torque delivery will be and acceleration will also be quicker than with a smaller diameter sprocket. However, top end speed will be compromised even if the engine has the power to achieve higher speeds. When the engine has achieved it's maximum rpm, regardless if it's making tons of horse power, the bike's speed will be restricted by the relative gearing. In most cases, even strong engines can only pull so much gearing. That's why it's important to have a balance between acceleration and top speed through correct gearing. With a snow thrower, one can achieve higher impeller speeds in lesser increments than 30%. If a person want's more throwing distance, but does not want to sacrifice too much torque, an increase of 10 to 15% might not be noticeable. Another thing to consider is that if you really want the throwing distance, re-power and re-gear. Some snow throwers are difficult to re-power due to controls locations. I know it would be very easy to put a bigger engine on the Simplicity 9528. However, I have no issues with snow throwing distance nor torque with the engine and gearing it has. The last big dump we had, it plastered heavy wet snow two thirds the way up the 35' light poles down at the street. That's good enough for me.

I picked up one of the high speed impeller kits for half price off of eBay. I am going to add it to my unit as well as a Clarence impeller kit (also on order). Dry powder throwing distance of mine is probably around 30-35 feet. I'm hoping with these two add ons I can maybe get toward 50 feet.

Is that realistic?

The Husky kit alone under perfect conditions should get me to 39-45.5 feet.

Do you think the Clarence kit could give me 5-10 feet more? I probably have a 3/8 inch gap at the impeller.

Great explanation Borat.  I agree with you completely.  For residential use, all of the 2 stage throw more than adequate distance.  There's no need for me to throw snow 50+ feet on my property, but it is fun to do it once in awhile.  Typically, 20-30 feet is what I usually aim for.  While throwing distance is not comparable to today's machines, the older 2 stage machines seems to perform well with their modest horsepower.  They are definitely geared lower and they make use of available torque.  They dive into end of drive piles and chew up that snow fairly well.

To answer mikiewest original question, I think Honda are designed to be used in rural area with large open space.  Therefore, distance is more important so that you don't have to throw the same snow over again.  I also noticed that it also has tighter stream of snow for less dispersion over long distance.  Because of the higher impeller rotation speed, this may also helps with dealing with slush, especially the almost liquid kind.  Not trying to brag but Honda was built to satisfy different performance requirements.  Given same hp rating, there's a compromise in volume to achieve longer distance.

Overkill on my part.... I am rural so throwing distance too far isn't an issue. It's more a "sleeper" competition with a guy down my road with the HS1132TAS. :-) He'll probably still throw further but I thought I'd give it a shot with a few bucks. aa335 wrote:
