They can be tempermental. The need to carry two gas cans, one for mix and one for the spreader. In my case I dont have gas spreaders any more, but now at least the blower gas can go in the truck.
They are loud, and have no low end torque. Once you have had a honda single stage, the two stroke units seem about 30 yrs out of date.
Now in all fairness I have never used a TORO, but the JD and two Husky units I owned were terrible. Hard to start at times as well. Broke every time I used them, and the simplicity is just a cousin to that. They all use the Techemsuh 2 stroke 6 hp engine.
is the main thing to me. They seem to blow out the muffler packing eventually and end up louder than H*LL!
I lost my earplugs one night and though I was going to go deaf from the noise from that Toro.
I also grew up with small Honda dirt bikes (CT70,XR75) and grew to love the 4 stroke "thump" vs the "ring ding" of the two stroke bikes. Not to mention the fact that we'd run those thing wide open from morning till dark (lots of kids) and they NEVER quit! Oil changes once a year, whether it needed it or not
That said, I know that the power of a two stroke, simpler design, and the lighter weight, were the reasons they dominate power tool use. But there has been a revolution in 4 stroke motors and there isn't the big weight penalty anymore.
Throw in the fact that they are MUCH friendlier to our envirornment (air pollution) and I'll be getting a Honda 621 sometime this winter.
Another problem with 2 strokes is storage. You have to run the tank dry before you store it for the season, or you get a carburator full of mud when you come back.
That being said, I have a Toro 2 stroke I wouldn't part with. I looked at the specs on Dino's Honda, it weighs 40 pounds more than my unit. Not something I want to throw on and off the truck all night.
I would say that since one is a 21" wide auger and housing and the other is a 20" wide auger and housing, that no they are not the same unit. Last year was the first year for the 520, but I see 621's for sale used in our local bargain news.
However for the money the 520 is a good deal. About 100.00 per hp.
I had a snapper that was wonderfull, 3 hp and 18" width, used to bring it up on roofs. Anyway the auger broke, was more for a new one than it was worth. That is when I bought the Huskies and JD, all three were junk.
So I replaced them with the Honda's and have been happy. I dont doubt that there are good 2 strokes out there, but I have switched to the hondas, and they work great for me.
MLB, I don't have the model # handy on my Toro, it has an 18" cut, is 2 stroke, and weighs 36 pounds. I've also used it on roofs, it's real easy to carry up a ladder. It has rubber paddles and will throw the snow 20' easily, I don't know the horsepower rating.
I had a Snapper 3201 that was the "Consumer reports" choice of about 15 years ago. That little 3.5hp sucker had more balls than lots of bigger blowers. Met the same end, bent auger, $190 for the part!
That's probably the size you're talking Pelican, weighed about 35lbs.
Nice to move around for sure. But I like the bigger bite of the 5 hp and I don't have any trouble with 75lbs out of the truck. Sure wouldn't want to carry them up ladders though
