Troubleshooting
| Symptom | Problem | Solution |
|
Disks not revolving.
| Scrapers adjusted too tight. |
Loosen scrapers so they
have just sufficient pressure to clean disks. Disengage scrapers when
not needed.
|
| |
Pressure not adjusted properly so furrow opener is not
in constant soil contact.
|
Increase pressure with
hydraulic down-pressure valve.
Adjust depth control press
wheel.
|
| |
Openers spaced too close together.
|
Adjust opener spacing.
|
| |
Insufficient spacer washers on disk hubs—Double-Disk
Openers.
|
Add washers to hubs.
|
|
Clogging of grain tubes and furrow openers.
| Using trashy seed. |
Use clean seed.
|
| |
Stopping machine in field and letting machine roll backward,
filling the bottom of boot with dirt.
|
Raise furrow openers before
stopping machine. Do not permit machine to roll backwards if it is
necessary to stop without raising furrow openers.
|
| |
Convolute tube rib collapsed inside opener boot.
|
Install tube correctly.
|
|
Fluted-feed shifter lever difficult to shift.
| Dirt on exposed tube. |
Remove dirt.
|
| |
Feed shaft locked up.
|
Turn feed shaft back slightly
with wrench.
|
|
Varying quantities drilled by individual feeds.
| Seed bridging in box due to unclean seed, inoculation,
treatment, or dampness. |
Use agitators.
|
| |
Feed gates not all set the same.
|
Adjust gates according
to instructions.
|
| |
Feed cup out of adjustment with the fluted-feed roll.
|
Adjust feed, as shown.
|
| |
Section of grain box emptying unevenly.
|
Adjust cups.
|
|
Quantities drilled not agreeing with seed chart.
| Feed gates improperly adjusted. |
Adjust gates according
to instruction.
|
| |
Heavier or lighter than average seed weight.
|
Check quantity drilled.
Check seed density.
|
| |
Improper tire inflation, tire size, or tread.
|
Inflate tires.
|
| |
Feed cups not properly set.
|
Check cup adjustment.
|
| |
Excessive field speed.
|
Reduce ground speed.
|
| |
Drive wheel not contacting ground.
|
Reduce hydraulic down-pressure.
|
|
Bunching and skipping.
| Improper adjustment of furrow openers resulting in openers
not penetrating low spots or “bouncing” over rough ground.
|
Prepare seedbed, adjust
furrow openers and reduce operating speed.
|
| |
Improper cup setting procedure.
|
Use correct procedure.
|
| |
Double-disk opener not turning smoothly.
|
Loosen scrapers, adjust
disks.
|
| |
Seed caught in tubes.
|
Make sure tubes are properly
installed.
|
| |
Stopping machine in field.
|
Stop only at ends of field
whenever possible.
|
|
Lack of penetration.
| Insufficient down-pressure. |
Increase down-pressure.
|
| |
Insufficient seedbed preparation.
|
See individual opener for
seedbed requirements.
|
| |
Excessive field speed for field conditions.
|
Reduce ground speed.
|
|
Irregular grass seed distribution.
| Seed tubes clogged with foreign objects. |
Remove tubes and clean.
|
|
Varying quantities between individual feeds.
| Distributing light chaffy seeds. |
Mix seed with heavier seed
or other material such as cracked corn to give it weight.
|
|
Row markers.
| Marker raises and lowers voluntarily. |
Check your tractor hydraulic
system. See your John Deere dealer.
|
| |
Markers will not raise or lower.
|
Air lock in hydraulic hoses.
Bleed hoses.
Selector valve malfunction. Check valve.
Selector valve malfunction. Check valve. Check hose routing.
Hydraulic cylinder malfunction. Check hoses.
Remove
lock up pin.
|
|
Openers drift down after being raised.
| Contamination in V1 ball check assembly. |
Remove ball check assembly
from V1 port, clean in mineral spirits and replace.
|
| |
Piston seal in hydraulic cylinder leaking.
|
Close transport valve and
disconnect hydraulic hoses. If openers continue to drop, replace piston
seal.
|
|
Pressure gauge near zero when openers are lowered and
SCV lever is held forward for a few seconds.
| Hose routing between pressure control valve and opener
cylinders incorrect. |
Route hoses per Hydraulic
Diagram-Opener Cylinders.
|
|
Openers rise when SCV is held forward and lower when
SCV is held rearward.
| Hydraulic hoses are connected to tractor incorrectly.
|
Interchange hoses in SCV
coupler.
For Tractors With Closed Center Hydraulic Systems
|
|
Pressure gauge shows zero when openers are down.
| SCV lever too far forward. Valve in float position.
|
Install R52667 SCV clip
in proper position to hold SCV lever forward, valve open.
|
| |
SCV lever not far enough forward. Valve in neutral position.
|
Install R52667 SCV clip
in proper position to hold SCV lever forward, valve open.
|
|
Openers do not “float” over undulating ground.
| SCV lever not in forward position. |
Install R52667 SCV clip
in proper position to hold lever forward.
