Well I finally figured out the pto on the 5020 there is a pto disconnect lever on the floor board of the cab someone had turned that lever to the disconnect position flipped it the other way and the pto started working again I don?t Know why they would put a disconnect lever in the system but they did . I wish the publishers of i&t would try just a little harder to make their manuals Easier to use the information Is usually in there it?s just finding it and putting it together so you can actually use it . The factory manual is worth the money just for the description of how the various systems work and all the information is grouped so you can find it
