- edit. I was thinking the KS66, but the idea should be the same. And I assume it still takes a mountain of a man to move that one as well-
Yes. I think if you pulled the lower pins (the gold oval shaped things) that attached the subframe from the blower then you can tilt the back of the subframe high enough that it will 'unhitch' from the blower. Be careful, that subframe is a lot heavier than it looks. And the blower itself is like 700 pounds or something. You might want a helper to prevent it from falling forward. (and possibly lifting the subframe)
Once its separated, the square portion of the subframe should fall enough to get the pin out.
I am sure it can be done, but the subframe needs to be attached to the tractor first, then use the subframe to lift the blower. And removal should be the opposite. They shouldn't be stored 'assembled' for reasons that you unfortunately discovered.
Good video (though I think he attaches the hoses wrong the first time, iirc) that explains it pretty well. I use dollies for mine, but the idea is the same.
