Ok, have a 1a tiller that had extensions on it that I sold to fellow cubber on here. I got one extension off but the other side was giving me a hard time so I took it to my local cub dealer figuring they'd have no problem getting it off. Let me state that I got the tine assembly off, I couldn't get the extension shaft out. So after $108 the pic is what I'm left with, still have the shaft lodged in there too! To me it looks as if the integrity maybe compromised. I'll get the shaft out, but is there any fix for the deformation in photo?? I kinda want to call the dealer and raise a rukus
