SW Montana | So we have a 645C Challenger hooked to big baler, and the PTO will not stay engaged and also disengages if you rev up engine to fast, even if baler pto is not hooked up. Ran the PTO calibration and didn't change anything. It will stay engaged if no baler is hooked up and very slowly bring up rpm. I have had it finally stay engaged with baler if I go on/off about 20 times at idle or 1200 room but as soon as I bale and get varaition it will disengage. Have also replaced one PTO sensor and tried swapping the two with no success. Any thoughts? | |
