Troubleshooting
Problem
Solution
Drill raising and lowering rough and uneven
Check for too little play in slide-block area. Refer to Maintenance, “Mainte-
nance and Lubrication,” page 68.
Check for air trapped in hydraulic lines or cylinders. Bleed hydraulics if nec-
essary. Refer to Bleeding the Hydraulic Systems, “Preparation and Setup,”
page 18.
Coulters not going deep enough
Retract tongue cylinder.
Add weight to hitch frame. Refer to Coulter Down Pressure, “Adjustments,”
page 26.
Too much weight is being used by openers; set drill openers to lightest
spring setting. Refer to Opener Down Pressure, “Adjustments,” page 27.
Shorten coulter springs to increase down pressure. Refer to Coulter Down
Pressure, “Adjustments,” page 26.
Drill not tracking behind coulters
Check if coulters are aligned with openers.
Check that pivot-lock tubes are in drilling position. Refer to Figure 6
Check if leaf spring is out of alignment. Refer to Leaf Spring Adjustment,
“Adjustments,” page 28.
Openers plugging in no-till conditions
Drill across standing residue.
Drill seeding too deep
Change the press-wheel setting. Refer to Opener Depth, “Adjustments,”
page 27.
Uneven seed spacing or uneven stand
Check for plugging in seed cups.
Check if seed tubes are plugged.
Reduce ground speed.
Check that opener disks turn freely.
Use a faster drive type and a lower seed-rate-handle setting. Refer to Setting
the Seeding Rate, “Adjustments,” page 30.
Increase opener down pressure so opener disks penetrate. Refer to Opener
Down Pressure, “Adjustments,” page 27.
Check for trash or mud build-up on optional Seed-Lok
® wheels.
Opener disks not turning freely
Check for trash or mud build-up on disk scrapers. Readjust scrapers. Refer
to Disk Scraper Adjustment, “Adjustments,” page 28.
Check if scrapers are too tight, restricting disk movement. Refer to Disk
Scraper Adjustment, “Adjustments,” page 28.
Check disk bearings.
Check opener frame for possible damage.
Check if opener disks turn freely by hand but not in field. If so, reduce down
pressure on openers. Refer to Opener Down Pressure, “Adjustments,” page
27.
Check press-wheel adjustment for seeding depth. Refer to Opener Depth,
“Adjustments,” page 27.
