In my experience with chutes clogging, this Toro powermax "bypass" thing would do nothing to fix the problem..
Every time I have had a chute clog, its due to very wet sticky snow..
the snow clogs up in the chute *above* the impeller, the spinning impeller isnt powerful enough to force it up and out, so it just spins, and if the snowblower is still moving forward the snow is simply forced out the sides of the bucket because it cant go out the chute..
In this situation, even if there was a "bypass" it wouldnt do any good, because there is only one possible way to clear the clog: shut down the machine and jam a stick down the chute to loosen it up.
So, I dont see how this Toro bypass thingy is supposed to help..
If the chute is going to clog, its going to clog..whether or not the bypass is there.
and once it is clogged, the bypass does nothing..
I suppose this bypass could slow down the formation of a clog..
but I dont see how it could prevent it.
it cant prevent the snow from building up above the impeller, and eventually closing up and clogging.
maybe it could slow down the snow volume through the chute enough to prevent a clog in the first place..that's possible...maybe.
but wet sticky snow is still wet and sticky either way..I think if the snow conditions are good for clogging,
its still going to clog.
