Your tractor was built in March 1960 and is actually a Super Major, 51 HP. There is therefore a distinct possibility that you have a "live clutch". These were not available on Majors until after 1957. Look under your clutch side foot-board. You will find the clutch pedal works in a "bent metal" frame. About halfway down that frame there may be a pin across that prevents the clutch pedal from moving further. This is to prevent wear on the PTO side of the clutch when it is not in use. Remove the pin and your PTO clutch should work. It may be that the PTO plate has stuck to the drive plate. This may free if you have any hard going. When you hit the hard work, push the clutch right down and after a couple of times the clutch should free. If not, its a splitting job. The clutch pedal should have about 1/2" of free play from the foot-board to the point at which you feel it getting harder to push. If there is more than this, shorten the threaded rod that works from the clutch to the place where it goes into the clutch housing. Reduce the free movement to between 1/4" and 1/2". Try the clutch pedal fully down. your PTO should stop. The gear change for the PTO and the main box is never a "clean" change. There are no syncromesh on the gears, you really are moving one gear into contact with another. Don"t rush to change when you first put the clutch down. They are built like a tank and will run for years yet. I still use a 1952 and a 1960 tractor myself.
