I've was mowing & stop for awhile and went back to cut again,put the pto on for the deck & it didn't come on the first time,but I push it in & out again and it came on.Since then about 2 weeks later,I started the tractor and then went to put the pto on and it did not come on at all. I've changed the switch and checked the 2 fuses,now I wondering how to change the pto clutch.Can you tell me how or did I oyer look something.
