A month or so ago, my John Deere mower stopped mowing. It still runs like a Deere, it just doesn't mow like one. After a little investigation, I noticed that the deck was disconnected from the PTO, it appears that some component of the locking collar for the PTO drive shaft has failed. I took it to a local Deere dealer. Initially they quoted $420 to replace the entire shaft, then they said I could just get half the shaft with the locking collar for about half of that. This still seems a bit ridiculous. I cannot quite figure out what fell out our broke so that the spring that provides tension is no longer held in place by the ring at the base of the collar. Does anyone have any suggestions for repairing this?
Looking at Buy OEM Parts it appears that I may be able to get by with the AM133972, but I'd still rather fix than replace, if possible.
Any suggestions?
Thanks!
