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

I didnt even know this model existed! When I seen how big this motor is in a 28" width I almost $#%* myself! lol I thouht this mountain motor only came in 36"+ wide units.

How does this thing turn? How does the power steering compare to that of a Toro?

I am picking up the Pro 28.  The ATC is not powersteering.   IN FACT it's harder to steer under power than the Toro.  The difference is that when you are turning under power the OUTSIDE wheel released and the INSIDE wheel is powered.  Not ideal for turning.  The thought process on the ATC is to keep the machine going straight.

I'm having trouble understanding this concept.  How is this an improvement over solid axle between two wheels?  If you want it to go straight , don't you want the two wheels rotating at the same speed and torque? 

I can see Ariens ATC will allow gentle turns while under power, but for 90/180 degree turns, I think the Toro trigger systems seems to make more sense to me.

This is question for Toro owners, can you feather the trigger to turn more or less as desired?

It seems to that ATC is a step above fixed axle in some situations, but it is not superior to the trigger release just because its different.

The ATC is "better" in theory because it's a "traction control"  If you start spinning a wheel it takes power away from it.  Also if you take on snow that unevenly distributed and it causes the blower to pull to the left it will take power away from the right wheel and only power the left in essence trying to keep the machine straight.  Thats it in theory.  In the real world I have no idea how well it works. 

Sounds like an implementation of "limited slip differential"

Essentially yes.

I think Ariens should make a video showing this ATC actually works.  Then they can convince would be buyers from buying Toro machines single stage snowblowers. 

I agree.  The problem is that people get it confused with the ability to turn around easily.  Not going to happen.   Now when you turn the machine around unpowered its fine.  The wheel disconnects and you can spin it right around.  But the with the Toro you can pull the trigger on the inside of the turn and actually power the blower around.

I have an old 1983 Cub Cadet 26" machine which has a complete differential with spur gears enclosed in the housing.  When it is driving forward it will pull hard with both wheels.  If i try to hold it back in the driveway it will spin both tires, but, whey you go to turn it if you hold back on the handle on the side you want it to turn to it disengages that wheel and only sends power to the other side making almost a zero radius turn. This machine with an 11hp engine and 20lbs of nose weight weighs well over 335lbs and it will turn on a dime and still pull with both wheels when allowed to pull forward on its own.  If you hold back on either handle it will turn in that direction instantly. It has a option to lock both wheels to a single axle but there is really no point in using it as it is a beast to try to turn with them locked.

Yeah thats exactly opposite from Ariens ATC.

I have an older Ariens ST1032.  Which has the lockable hub on the left side and the axle differential unit.  Which does function like a limited slip car rear end and as it has been described here.
I think I have only locked the axle maybe twice in the last two years  When the hub is in the locked position both wheels spin at the same speed. Which makes it a real bear to turn.
Actually it won't turn you have to drag it to turn it.
With the hub unlocked I can literally make a 180 degree turn with little effort, I've done it one handed.  If I'm in first or second gear I can turn left and almost keep the left wheel planted and simply pivot around it. While the right wheel drives the blower around.  If I'm in a higher gear I'd have to almost run to keep up with it as it turns. The only situation that locking in the axle would probably be useful in. Would be trying to blow deep snow going up a rather steep incline. Or simply driving the blower through deep snow. I've never had a traction problem with the hub unlocked regardless of the snow depth. Just my observations.
