Well Hey!!! Thanks for all of that!!! I can only say that since the dreaded repair and modifications, the tractor has been running just fineish....
Really, It has held up well, until last week.... I was mowing a 1 acre field of tallish grass and the PTO went! I'm guessing it is the independent PTO spur gear because I thought at first the drive shaft that had to get re-welded back together snapped, but when I put it in syncro PTO, I can roll the tractor in low gear....
So in Googleing PTO repair, my old threads came up!!! LOL... Now it is off to take apart the whole center section in order to open up the top of the box to see what is hiding inside.... Of course the repair couldn't be as easy as swapping out the syncro gear for the broken independent gear... or the independent gear fell off when the snap ring wore out.... Nope. I betcha a bad sealed bearing went and sheared the pto gear shaft made of unobtanium....
