140 Clutch Question

I was reading through the service manual for the 140 (30,000 and up) got to the section on power train and so I went out to look over my tractor and make sure I could find everything and I certainly cannot find the throwout arm and bearing.

I've searched here and on WFM and cannot find anything definitive. Did JD get rid of the engine disconnect on the later model 140's? Any body know why?

Thanks,

Jeff
