So I just inherited a 1973 cub cadet 149 from uncle who passed away, and couldn't be more happy to be a cub cadet owner!! It had sat for a couple years now, but he had the tractor and motor restored just before it sat. It would not start so I took the carb off and rebuilt it, drained the gas tank and cleaned it and now it runs perfect! Then hooked up the QA42 and when I started it the auger started moving. So the investigating began trying to adjust when I realized the wear button was ground down to nothing. The restore included paint on the pto which I am wondering if that caused problems or if it is just seized. The one throw out lever is not connected in the center to the thrust button anymore and the screw just spins, so should I remove the pto and rebuild or just try to put new wear button on and see if it works?
