Yes, that is very helpful, Thank you! But i have about decided to take it to the John Deere dealer. I think now if mine did the same it might come off, but there are some others issues that might require expert attention, so I think I will bite the bullet in the hope it can be all put to right; that and I am 75 Years old and I know my limitations.I JUST PUT A NEW ONE ON MY 225 . I took the drive belt off ,which let me move the motor forward about a half an inch,then i wedged a screwdriver under the front of motor between frame and motor. It took a little fine manuevering but i did get it on in about 30 minutes. Hope this helps.
