Toro Super Recycler-- self-propel adjustment stuck

[Yabadabadoo]

I'm talking about the from the handle cable to the rear gearbox will not move the engagement adjuster its attached to. The cable is fine, unhooked it from the adjuster and manually still get it to move. Opened up the gearbox and couldn't make it move from the inside either. Hesitant to take all the gears out cause sure it's not a gear issue---- cant dope out why the adjuster wont budge. Anyone with any thoughts, wouldn't expect such a simple thing to be so perplexing
