4035 PTO only works on Automatic

[RockyNY]

We used the PTO for the first time on our 2 year old 4035 a few weeks ago, and found that the PTO will only work on the Automatic setting. The automatic setting works as expected, with the PTO shutting off when the arms are raised and turning back on when they're lowered. However, on Manual, the PTO will not turn on, period. The on/off switch will not even light up (it does light up with the mode switch on Automatic). I was going to give the dealer a call, but I thought I'd post this up and see if anyone else has had this issue.

Most likely the PTO mode switch needs to be replaced.

Just a quick update in case anyone else runs into this. I didn't have time to get it in to the dealer until now, but they are backed up due to harvest season and my window of opportunity isn't very big. I decided to check it out myself. I removed the instrument panel and tested the PTO mode switch, which tested OK, I checked the connections where the switch plugs into the harness and that was OK also. Just a couple inches below the switch connection is the PTO relay, I jiggled the connector on this relay and PTO manual mode started working. A little more jiggling and it stopped working...so there's a bad connection in relay harness.
