It's complicated to explain and nearly impossible for some to comprehend. What should really be the focus is what it does, not how it works.
Snowmann, one thing is for sure...it's very difficult for ME to understand. And all I'm thrying to understand is what they do. After all my reading I think that it works like this:
Ariens Pro "wheel" models - I think that they have a true differential that automatically supplies a percentage of the total power independently to the right and left wheels as required. On straight lines the power might be divided 50:50. On turns the power might be divided 90:10.
Ariens Deluxe "wheel" models - I believe that they have a remote lock/unlock lever that locks the axle so both wheels are powered the same. When unlocked the left wheel is free turning but the right wheel is powered for easy left hand turns.
Ariens Platinum Deluxe "wheel" models - They have the automatic traction control that I think works the same as the remote lock/unlock lever however the locking/unlocking of the axle happens automatically without the need to manually operate a lever.
I might be all wrong with my perceptions so please feel free to correct anything that's off base.
In marketing 101 you learn to never mention a feature without it's benefit. Example, the Ariens Deluxe 30 has a dual handle interlock system, which to the user means...(insert benefit).
Whoever manages Arien's website does a nice job of listing all the features...but a terrible job of associating a benefit to those features.
