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

is this a quality product.......or would i be better off for a few hundred, going with the 28" toro powermax?

that's strange because toro did have problems with their plastic in the beginning.It was cracking and there was a recall on their machines.The dealer told me.And I'm referring to the frame being steel and the chute etc.Like I said,steel doesnt crack,plastic does.And you cant convince me that the plastic chute rotator is more robust than my chute rotator/deflector.

The Toro PowerMax discharge chutes are made from HDPE and have no Teflon content. They (and other PowerMax plastic parts) were made from a different polymer material when the problems ocurred on early models.

The term you are searching for on the Ariens shear bolts is "stress relieved", not "pre-stressed". It is an annealing process to eliminate hard spots in the steel caused by the carbon content. It provides for a very repeatable and predictable shear. The Ariens Deluxe XS and Pro gear cases can easily shear the Gr5 bolts the Toro uses. They'll also snub 13hp engines if the shear bolts fail or the augers seize to the shaft. Throw some grade 8 aircraft bolts in and this will be the case (and yes, the warranty will then be void as with any non Ariens prescribed OEM shear bolt). However, just because you can put a gun on safety doesn't mean you point it at your head when you clean it, if you get my drift. A gear case replacement will metaphorically have the same painful consequence (financially) on the off-chance something fails and the warranty is expired or voided.

That said, the Toro gear case is hardly "without equal". The comparable Ariens models (XS Deluxe and Pro) use a similar sized alloy steel gear, similar 4 lead worm, similar use of EP/GL rated gear oils (versus less capable grease), similar ~1/4" casting wall, and identical diameter 7/8" input shaft and 1" output shaft. The Ariens also has a true worm/worm gear mesh where the Toro uses a worm/helical gear setup to make it easier to manufacture. You can PM mold helical teeth, but a true worm gear has to be machined (which is more difficult with a steel gear, versus the more common free-machining bronze gear). The less-than-ideal gear mesh present on the Toro creates higher localized tooth stresses (sliding point contact instead of line contact). The Ariens also uses an asynchronous "hunting tooth" design which causes the teeth to break-in over time to mate perfectly for longer life, and, in this particular case, boosts the ratio for increased capacity (39T w/4 leads versus 40T w/4 leads). This feature also further reduces tooth stress, reduces operating oil temperature, and lessens the burden on the oil's EP additives.

The top-line Simplicity gear cases are a tier below these with 2 lead worms, relatively small diameter bronze worm gears, and smaller 3/4" input shafts (hidden under some rather enlarging plastic sleeves). If you run the math on these the load carrying capability is down ~30% when compared to the equivalent Ariens gear case. The aluminum versions go without auger shaft bushings (shafts run on the housing casting) and the cast iron versions use grease instead of gear oil. They do use a "hunting tooth" design, but with 21 teeth and a 2 lead worm they effectively reduce auger RPM's when compared to others (with equal impeller speed). Given that impellers are always the capacity bottleneck, this is less desirable. These gear cases are not known to be problematic in either version (that I'm aware of). I'm not sure about the Murray style gear boxes that go on the L1226E and the Intermediate series (and the comparable Snapper bretherin), but they're probably another tier below. The questionable application in my mind is the use of the Murray/Brute style auge gear box on the 2009 L1226E with the 14" augers (this gear box has historically run only 12" augers).

The mainstream MTD's are at the bottom from a pure specification standpoint. Very small diameter bronze gears, 2 lead worms, 3/4" input and output shafts, and grease lube with no apparent serviceability capability of the lubricant. EP/GL gear oils are far better functionally but higher viscosity grease is easier to seal which is probably why there is no fill point on these.

There are many variables going into making a plastic part. Having problems with plastics initially is not unusual, and expected by the designers and molders. This should not prematurely fault on plastics in general. Anecdotal failures only gives us the occurence/frequency of failures. Robustness has little to do with the material itself. There are many robust designs that are lightweight and plastic. Look around. I will leave it up to you to be enlightened or call it a day.

yes you have enlightened me.Plastic doesnt crack and is stronger than steel.Are you for real?Guess what steel doesnt crack in the initial stages or ever .I guess snowmann put u(AA) and ajallen in your places about the Toro auger gear case being better than the rest.Thats the problem AA.You think you know but snowmann does know.....

Hmmm...

I'm reading and reading... But what about the " Husqvarna?" is the 14527 as good or better as the toro/ Ariens ?

I am slightly leaning toward this unit as well over the Toro 1028OXE. The Husky has the same steering settup but with a larger engine and it a bit narrower. Even snow blowers direct like the the Husky over the Toro!

get the huskvarna 14527-XLE. its only true dealers. its a monster with all the goodies...
