Craftsman Snow Thrower always in drive

I have a Craftsman 27" 8.5hp Dual Stage snow thrower (#536-881851) and the problem is that the drive wheels remain engaged and turning despite the position of the traction lever and any cable adjustments.
Ive removed the bottom plate to investigate and discovered that the friction wheel and friction plate are always in contact with one another. There is no gap between the wheel and the plate, and the friction plate assembly is in the most retracted position.
I initially thought that the plate assembly might be stuck against the friction wheel, but when I loosened and removed the friction wheel, I was able to freely move the plate assembly normally with the traction lever or by hand. It would move and return to its normal spring mounted positions.
But when i reinstalled the friction wheel, I noticed that the wheel would immediately be touching the friction plate assembly instead of having any gap between them despite the friction plate assembly being in its most retracted position.
So for now the thrower remains in drive when the engine is on.
What do you think?

It's been a few days, maybe you resolved the problem. If not, I think that there in a problem in the linkage,probably on the drive end. You have to operate the drive lever, and observe what happens. There should be some movement to and from the drive discs. there should also be ether be a lug, or a space at the center of the driven disc, to prevent contact between the two discs. There should be some kind of adjustment there to take care of that. You should be able to get some idea from the owner's manual, on the parts display pages.
