Hello everyone, the PTO on my 782 began working intermittently in the late summer, then not at all in the fall. I would like to figure out the issue and if needed replace the pto so I can still mow or rototill with it. Here is what I have tries so far; bypassing the seat switch, replacing the pto switch. Neither one fixed the problem. I am wondering if the next step should be to remove it from the front of the tractor and test or inspect it? How often do they fail? This could very well be original. Finally, how expensive are they to replace? Thank you for your help!
