How do you set timing on Massey Ferguson 124 baler?

To set the timing on a Massey Ferguson 124 baler, first, ensure the baler is disengaged and the tractor is off. Locate the timing marks on the main drive sprocket and the knotter drive. Adjust the knotter timing by loosening the set screws and rotating the knotter drive until the marks align correctly, typically at the point where the plunger reaches the end of its stroke. Finally, re-tighten the screws and verify the timing by testing the baler's operation.
