No Seed Flow Rockshaft hubs locked out Engage hubs (page 22).
Seed cup door setting is smaller than
seed size (large seed, Main Box) Open doors for even flow with minimal crack-
ing. See Seed Rate Manual.
Height switch mis-adjusted or malfunc-
tioning Check that clutches cycle with height switch
operation. Readjust switch engagement point
(page 71).
Clutch failure Lower drill to engage height switch and
clutches. Shaft should be impossible to move
at calibration crank if clutch is engaged.
Chain break Check all stages of chains from ground drive
wheels to meter boxes.
Seed run-out Check seed box.
Obstruction in meter. Clean-out meter.
Seed plugs installed Remove any unintended seed tube plugs.
Uneven seed spacing Seed-Lok plugging Lock up Seed-Lok, page 52.
Drive Type too low Use higher Drive Type and lower handle rate.
Damaged or missing seed flap Replace seed flap.
Openers not penetrating low spots Check/adjust frame height, coulter settings,
row down-force and weight available per row.
Opener disks not turning. See “Opener disks not turning freely” in this
Troubleshooting chart.
Drill boxes do not empty
evenly Drive Type (Main Box) or rate adjusters
not the same on all sections Check and correct.
Opener seed tube plugged. Raise drill and clean out seed tube with wire.
Chains broken or skipping. Check chain condition and slack on all sec-

Concentric passes - if planting in turns,
inside boxes plant less than outside. Reverse pass direction periodically, add more
seed to outside boxes, or use opposing
passes.
On 7.5in/19cm spacing, center box
empties first, as it has one more row
than wing boxes. Add extra seed to center box.
Rough or steep traverse field condi-
tions moves seed in boxes. Add extra seed. For Small Seeds, install
dividers.
Openers drill too deep
(bulldozing) Too much opener spring force. Reduce opener down force to match condi-
tions (page 47).
Frame height too low Check and adjust (page 17).
Incorrect press wheel adjustment Check and adjust (page 53); however, do not
use press wheels to compensate for incorrect
down force.
