My 567 jd baler has net wrap but is not working correctly. After the bale has reached the correct size and it calls to wrap the net the actuator that controls the net wrap doesn't move far enough to make the rollers engage. I can stop and open back door (net wrap door) and the actuator cycles perfectly and the wrap wraps the bale wrap correctly. Nothing on the back net wrap door is touching the actuator arm anywhere. The actuator is new and the voltage is correct. Any ideas?
