Lifting Rod Won't Stay Tight

[bambam31]

The right lifting rod on my 3PH kept getting loose today. I tightened the locking nut with a wrench but it kept working itself loose. I was covering seed with my disk and was not in the float position. I was in in the 5-6 position. Could this have been the problem?

Sounds as if you're not applying enough torque to the "lock nut". I'm curious since most 3 pt hitches have no down pressure how can one operate a 3 pt implement without the 3 pt floating?

I was covering seed and I did not want the disk to fully contact the ground and bury it too deep. So I just ran the disk in the 5-6 position instead of the float position. It kicked up enough dirt to cover and I have a 6' post pulled behind my disk for leveling.

I'm not trying to argue but your disk was still in "float position" no matter where you had the control as long as not fully raised position. I agree having control lever in the 5-6 position was limiting the depth/penetration of the disk which may be what you referring to.

I fight mine some times. I usually slip something over the cross stud on the top link and apply counter pressure to the lock nut. IOW, the lock nut doesn't lock unless more force is applied. Its more likely to be a problem when there is load and vibration on the top link.
