Used Comparison: Toro 521 ('89) vs. Ariens 624 ('74)

Was wondering what people's thoughts were on these two units? Right now I have an average sized driveway, narrow but longer than most. Snow is northeast type, and I'll get occasional blizzards. I'm guessing the Ariens is a wider auger unit at 24" based on the numbers? They both need some minor work (carb for Toro and belt for Ariens). Which is the better one? And if one's engine is on the weak side, what's a better choice for a Predator drop in? I'm also looking for overall durability of them.

Wow what a difference in age. I'm familiar with 80s Ariens, not 70s. The 21" width is great for power ratio for a 5hp. The 24" is OK and most situations fine. Because of the age it's probably a heavy machine. I don't know anything about parts availability but Ariens is known for being able to get parts for. There are enthusiasts on here who are happily using 70s Ariens as their main machine.

The Ariens Most Likely has a Differential, and are Virtually Bulletproof. I'd get the Ariens. Easy Upgrades are the Chute, and Impeller Seal.

I have a couple of toro 521's and have no problems blowing snow with either. one has an impeller kit and they don't need a differential to aid in turning them. I've always had good luck with toro products so I pretty much stay with the brand never used any ariens snowblower but looking for one

Both the Toro and the Ariens are good old school machines. I would try each and make your own decision. You won't go wrong with either. My own preference would be the Ariens....I've had several of that model and they are totally bulletproof. Very easy to upgrade engine with a Predator for cheap money and almost bolt on. Same with the Toro. I've had to replace impeller bushings on the Toros, but the Ariens uses a bearing that seems to stand up better.

I presently own a Toro 521(with a 6.5hp HF "Greyhound" engine) and used to own a mid-seventies Ariens 624.

Frankly,I hated the Ariens and couldn't wait to get rid of it.It had an unusually narrow discharge opening and shute and would only throw the snow (dry) about ten-fifteen feet,with wet snow,it was useless.

It also seemed very under-powered for a 24" machine.I can't say if all Ariens 624s are like that,I've never used another one.I presently also own two Ariens ST824s and like them.

The Toro is a surprisingly rugged little machine that's very lightweight and easy to maneauver.No impeller mod is really needed,mine will throw anything from water to heavy,sticky snow just fine.It throws it further than either of my two Ariens and probably my Allis(Smplicity) Sno-Pro 828,too.

The Toro's auger gearbox is huge for such a small machine,in fact,I believe it's the same one used on the 7 an 8 horse models.The impeller shaft is a full 7/8" in diameter-that's larger than my Ariens and my Allis.

The Toro's wheel drive system is all gear drive-no chains and is easy to work on.

On the negative for the Toro-it's a tad slow and small to rely on as a main/one and only snowblower.I would want the 724 or 824/26 myself.
If you never had snowfalls over a foot,Id say go for the 521.I've done 20 inchers with my Toro,but it do take a while.
Another negative is that Toro parts are relatively expensive compared to other brands.I can buy a drive disk for my Ariens 824 for less than half of what the 521 disk costs and Ariens parts are far easier to come by than Toro-in MY neck of the woods.

Another note:I can't say in all honesty that the Harbor Freight engine on the Toro actually seems more powerful than the original Tecumseh 5 hp.In fact,as far as torque goes,I'd give the SLIGHT edge to the Tecumseh.I don't really care for Tecumseh engines,but I'm being truthful.

However.... the Harbor Freight engine is a LOT quieter,better on gas,smoother and will start on the second pull at 40 degrees or 4 degrees below zero.The Tecumseh might start on the first pull or the twentieth-I was never sure.

Thanks everyone - unsure I'm going to go for either, looking at the size of them and thinking about my driveway, I think a bigger machine is the way to go. Snow season is ending, I've got some time.

Personally, I'm not a fan of the old old ariens that use a lever by the chute to engage the drive and augers, it's a particularly dangerous and archaic design. Im not sure what that Ariens has but, I think sometime in 74 Ariens made a change to a console mounted auger engagement. That generation of Ariens i can appreciate. The right combination of sturdy steel with slightly more contemporary controls.

I had a 3521 toro, same machine just smaller engine. I installed a predator 212cc and snow hogs... it was very good. Only modification nessesary is with the chute control. Weld in a universal with a brace (better) or a large spacer near the handle to clear the engine (works but widens the footprint considerably?

7hp to 21" bucket is a real sweet power to width ratio.
