Row Unit Shut-Off
To shut off seed flow to individual rows, such as to
operate with an alternate row spacing, there are two or
three steps involved:
1. Block the seed flow to the row with an optional seed
tube plug. See page 163 for ordering.
2. Re-calculate the drill’s swath, and check for any
changes needed to:
• marker extension (see pages 21 and 176) and
• calibration (step 15 on page 45).
3. On 10HD and 25 Series, reduce needless wear on
the unused rows by locking them up. See page 105.
Seed Meter Setup and Adjustment
Your Drill was originally supplied with a specific seed
meter type and internal components optimized for a
particular crop. Depending on the meter type and
configuration, there may be adjustments available.
On 10HD and 25 Series openers, you can also entirely
change the meter as your crop mix changes.
All models support:
•
Great Plains Singulator Plus™ meters
The 3N4010HDP and 3N4025 further support:
•
Finger pick-up meters.
The 3N-40 does not support feeder cups. Use a
Singulator Plus™ meter with specific wheels for
volumetric applications.
