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

Preface: I've have has a HS520. Due to space contraints, etc - I'm not looking at 2 stage. Single stage for the most part is a perfect fit just short of....living on the right side and the plows only plow to the right so I cam constantly getting plowed in... Throw is fine already on the HS520. I was only curios does the 421/221 or even any current models on the market may have a bit more bite on the EOD/overnight plowed snow...

AA - read you past threads. Can't seem to figure out based on date but do you feel the *newer - later revisions* of the 520AS has comparable *uumph* compared to the 610... The current routine is to keep ontop whenever the plow comes around and then follow up right him as oftentimes, what get's plowed is the hardened snow or between that and the liquified stuff that just turns into Ice Bricks if you don't deal with it ....and overnight with no activity.

The Honda HS520 does not compare to the Honda HS621 or the Toro 221 at all in my book.  Both the 621 and the 221 have considerable power advantages over the 520, which uses a low-end, honda in name only GC series 4 stroke.  The 221's 2 cycle is 141ccs and known within the commercial lawn mowing industry to be the most powerful walk behind mower engine made (known as the lawn boy duraforce in those circles) and the HS621 uses a commercial grade true honda GX series motor.

I find the impeller design to be a little better on the Toro as well, but I wouldn't turn down a Honda HS621 were one to come my way.

I had a Toro Snow Commander last year (which also uses the 141cc R*Tek 2 stroke) and while it had plenty of power and was big, I found it a bit awkward to use when compared to the 221.  It didn't seem to offer any advantage other than 2 inches more width (who cares) and if anything was slightly less powerful-seeming than the 221 because it had to turn an extra paddle (3 as opposed to 2 on the 221).

The briggs model single stage (seems to be everyone other than toro and honda have bought and badge engineered this model for 2010/2011) looks promising, especially in the auger design, but I can't see that motor being more powerful than the R*Tek, especially when the 8.75 "gross torque" OHV briggs mower engines can't hold a candle to the Duraforce (I would know, I have both).

As far as the squall, no amount of power will help that thing until it gets a better auger design.  The auger like it has is inefficient and prone to clogging - in fact that design is primarily responsible for single stage snowblowers getting a bad name.

I had an MTD single stage with an auger that looks the same as the Squall 2100 I saw some pictures of and that thing clogged constantly.

On the other hand, it was free and was better than shoveling.

When I switched to my 1985 Toro 3521 2 stage blower last year the difference was like night and day.  I had 1 clog all year and that was due to
a loose auger belt.  In fact it was loose enough that it clogged because the impeller completely stopped.

Goes to show that there's more to snowblower performance than just a big motor.

Chefwong,

I assuming you're asking about how the current HS520 compares to the older HS621.  I had both at one time so I can tell you my observations.  The newer HS520 is lighter and more nimble, too nose heavy for my taste, just a little forward tip and the wheels easily comes off the ground.  Seems like all the weight is on the paddles.  I don't like this because the snowblower wander and bounce around a lot when the rear wheels are not on the ground.  The HS520 does have more efficient flat belt for power transfer, lighter auger/paddle assembly, and throws snow further, not by a lot though, 5 feet or so. 

However, when dealing with wet heavy snow or slush, the HS621 is has more torque and the stiffer and flat center paddle will push that stuff out of the chute better than the HS520.  The HS520 will stall when pushed too hard, it's much harder to do that with the HS621.

In fact, I had my Honda HS621 run against the neighbor's Toro 221 in the thick heavy wet snow and he constantly ease up to let the rpm build back up, he constantly have to forward, stop, forward, stop.  I just push the HS621 steadily at about 1 inch per second and adjust the speed if the engine tone drops.   Pretty much like what this guy does:  http://www.youtube.com/watch?v=S_O6g_uHAA4&feature=related

Besides that test, the Toro 221 performs better than the HS621 in all other aspects. 

I will still keep my 10 year old HS621 forever though until I can buy a new one in the US.  I'm in the process of repainting it to make it look new again.

Thx all for the feedback...While the 2 stage is probably the Correct Machine given the *ultimate application* - plowing myself out after getting plowed in (they only plow to the right ). The only downside is footprint. The single stage I can store when the season is over. With a 2 stage, even a smaller monster engine 24-26" machine, it's too big of a machine for me to store at this time. That unfortunately is the compromise that I will suffer, and thus the single stage takes precendence.

No problems.  Remember we're here to help if you're itching to spend money.  :)

As far as hiding it from your wife, well, that's your problem.  :)

Heh. We all have moooooor power envy at times ;-)
