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.

left hand threads) that mounts the blade to
the opener bar.
2.
If equipped with soil control devices, remove
the locking arm 3/8 inch bolt (2) and the
locking arm (3) first.
3. Slowly remove the blade (4) and bolt (1)
together being careful not to drop and lose
any shims (5).
4. Remove the 3/4 inch bolt (1) and transfer the
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).
7.
Tighten the bolts and recheck the pinch point pressure.
8. Install the soil control devices, if equipped, and set the angle while tightening the 3/4 inch bolt (1).
9. Check the pinch point pressure.
10. If the pinch point pressure is correct, attach the locking arm (3) and the locking arm 3/8 inch bolt (2).
