3.17.5.2 Check for a tight pinch point
Procedure
1.
Raise the drill until the openers are off the ground.
2.
Stop the tractor, stop the engine, apply the park brake, and take the ignition key with you.
3.
Grasp each blade from behind and rotate them independently in the opposite direction of each other.
Result
The blades should glide against each other easily without binding.
4.
If the blades bind or work against each other while rotating, install shims between the opener bar and
the blade to space them apart.
Shims are sometimes required when new blades are installed.
5.
Add the number of shims necessary to maintain the pinch point.

shims (5) from one side to the other,
depending on the adjustment required.
5.
Insert the 3/4 inch bolt (1) through the blade bearing and place the shims (5) on the end of the bolt,
against the bearing.
6.
Reattach the blades (4) to the opener bar with the 3/4 inch bolt (1).
