Outdoor Power Equipment (Lawn Mowers, Snow Blowers, Chain Saws and more) Discussions

Well I couldn't let it go.
It was just bugging me why the thing was so pitiful when it came to it's throwing distance.
So a few days ago I removed the steel that formed the center hub around the auger shaft.
Then made plates to support the center of the paddles and welded them in place.
Now it looks like most of the other Toro SS blowers out there.

Tried it out, and it really didn't make much if any difference in the distance.
And it had no effect on the engine performance.
So back into the garage we went.
Decided there was only one more thing to modify.
So I removed the stock pulley and replaced it with a stock pulley from another Toro SS.
Most of the pulley's are the same. But I think it may have come off a CCR 2000.
The stock SC pulley is 7 1/2" in diameter.
The replacement one is just a little less than 6" call it 5 7/8"
So a full 1 1/2" smaller.

Now the blower is set up just like most other Toros out there and the impeller
will be running at the same RPM as those blowers.

The really good news was that after I measured what new belt length I was going to need.
I found a great and helpful belt supplier on line.
vbeltsupply.com
I gave them the measurements told them what I needed and they said no problem.
$21.00 ($10 for the belt $11 shipping) and four hours later it was on it's way.
I should get it Monday afternoon.  So by Monday night I should know something.
It will be interesting to see how the added auger RPM directly effects the throwing distance.
And how the engine responds.  Removing the center hub steel plates probably dropped off
about 6 or seven pounds.  We'll see!

 

It think in designing the SC Toro tried, or was trying to design a machine.
That would have the snow moving, or snow processing capacity of a 2 stage.
Unfortunately what they seem to have wound up with.  Is simply a large SS machine
with a poor throwing distance.

My thought is this.  The 210R that I have has no problem handling 10 maybe 12"
of average weight snow.  It will throw it twice as far as the SC.
And although SS machines can be used for greater depths.  That really is not what they are designed for.
If your working with those kinds of depths on a regular basis. Your really needing a 2 stage anyway.

 Taking into consideration that my 210R or the 421
have only a 2 1/4" smaller bucket opening. It seems to me that the additional
2Hp of SC engine would have had enough power to handle the increased snow
from a wider bucket.  So why not just forget about building a SS blower that can maybe
handle 18" of snow volume.  Why add a third paddle to make that possible.  When the trade off seems to be
 a sizeable drop in throwing distance.  What they ended up with, is a blower that won't complete with a
2 stage.  And a blower that won't throw as well as some of their other Single Stages.
When it's being used in snow depths of 2 - 8"
I'm not saying that a long throwing distance is all that matters.  Because it's not.
But having an average throwing distance of at least 10 - 12' is an important performance factor.
Simply having a 24" SS blower with adequate power and a decent throwing distance.
Would still have given Toro a blower that no one else was offering.
Who cares if The SC will handle 18" of snow more easily than another SS blower.
If it won't throw it clear off your driveway.  Then what advantage does it really have
over a 210R, 421QR.
The Toro Power Curve designed augers with two paddles work extremely well.
The newer model SS blowers those including the 4 cycle engine. Have no problem
handling 8 - 12" of the right kind of snow.  I think Toro tried to fix or change something that
was working fine the way it was. Meaning they added a third paddle.

Snow never remains in the center of the bucket around the shaft.  For the simple reason that snow is always being pushed into
the bucket as the blower moves forward.  The snow is always being forced or pushed to the back of the bucket by the incoming snow.
Until you stop pushing the blower forward. 

I don't really understand why Toro felt the hub pieces were needed.  All they had to do was look at the performance of their other
models that don't have hubs. e.g. the 210R, 421, 621 and many others.  Why do those models perform so well without hubs?

Why add the hub and a third paddle.
In my opinion it's simply a flawed design.

But I do give Toro credit for some of the other innovations on the SC.
The tilting feature that let you control the amount of forward pull works very well.
The larger diameter and wider tires makes it much easier to push and pull.
And the extra pair of wheel underneath comes in handy when just moving the blower around.

LOL, That's a good question.
Everything that I've done to the blower so far can be easily undone.
And put back to stock.
I wouldn't mind taking off the third paddle and seeing how it performs with just two.
But that modification would be a little more difficult and time consuming to undue.
So I guess I'm done with it.
We got 8" of the wettest snow I've ever seen last night so I had it out again today.
The Toro 210R ran circles around it.  The only reason I still use it is that I love the powered chute
set up that I put on it. I do a few small commercial parking spots and it really helps out.
My 210R has a different chute rotation design that won't let me swap the set up off the SC.
Was thinking about buying a used CCR2000.  It has a chute crank that would except the powered chute motor.
Then I could pull the engine off the SC and put it in the 2000.
That would probably make a great machine.  Part out the SC sell the Suzuki engine out of the 2000
and maybe come close to breaking even. Also thought about trying to fit a Honda 6.5hp into a CCR2000.
 
It never ends!
