Soil Firming Device Adjustment; Rigid Scraper Adjustment; Opener Blade Pinch Point; Check For A Loose Pinch Point - CONCORD NT30 Operator's Manual

3. Operation
Result
If the measurement (A) is less then 2 to 2 1/2 cm (.75 to 1 in) increase down pressure in the monitor.
If the measurement (A) is more then 2 to 2 1/2 cm (.75 to 1 in) decrease down pressure in the
monitor.
5. Measure the frame height cylinders from the cylinder head casting to the clevis on the rod end of the
cylinder.
6. Determine how many stroke control segments are needed to hold the drill at this height.
7.
Place the same number of stroke control segments on each of the frame height cylinders.
8. Place the openers in the tire track in a higher setting if more down pressure is required.

3.17.3 Soil firming device adjustment

The purpose of the soil firming device (1) is to
prevent blowout and to minimize soil and residue
disturbance. For most seeding conditions, the
firming device angle should be set at approximately
28.6 cm (11.25 in) measurement (A). If you are
seeding excessively deep or shallow, you may
need to change the angle of the firming device to
match your conditions.

3.17.4 Rigid scraper adjustment

The rigid scrapers should maintain slight contact with the inside of the blades for best performance. If
adjustment is required, loosen the two mounting bolts and adjust the scraper. Tighten the mounting bolts.

3.17.5 Opener blade pinch point

The point at which the two opener blades contact each other is called the pinch point. The pinch point
must be properly setup with the right amount of pressure to maximize performance and extend blade and
bearing life. If the pressure is too tight, excessive wear, bearing failure and plugging may occur. If the
pressure is too light, bearing failure and seed trench deterioration may result.

3.17.5.1 Check for a loose 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 a blade from behind and rotate it in the forward direction.
Result
The pinch point pressure should be adequate enough to rotate both blades while turning only one. A
slight loss of contact during rotation is acceptable but ideally you want full contact between the
blades during rotation.
4. If the blades are loose, remove shims from behind the opener blades to move them closer together.
5. Remove the number of shims necessary to maintain the pinch point.
