    John Deere 4640 and 540 pto ?

    Hi I am wondering if you can get 540 pto for a 4640. I ran a 4640 on a 540 rpm before with a pto shaft adapter and didn't like it. Implement runs to fast and tractor has to be at low idle. Is there a pto reduction that is designed to fit on the back of these tractors so you can run a 540 pto...
