General Maintenance
Proper servicing and adjustment is the key to long imple-
ment life. With careful and systematic inspection, you can
avoid costly maintenance, downtime and repair.
Always turn off and remove the tractor key before making
any adjustments or performing maintenance. Securely
block raised drill before working under or around it.
1. After using your drill for several hours, check all bolts
to be sure they are tight. Periodically check and se-
cure all bolts, pins and fasteners. Tighten as specified
on Torque Values Chart, “Appendix,” page 29.
2. Clean or replace any fittings that will not take grease.
Lubricate the drill as noted under Lubrication, this
page.
3. Adjust idlers to remove excess slack from chains.
Clean and use chain lube on all roller chains as need-
ed.
4. Always maintain correct tire pressure. Refer to Tire In-
flation Chart, “Appendix,” page 29.
5. Check disk scrapers for proper adjustment. Refer to
Disk Scraper Adjustment, “Adjustments,” page 19.
6. Replace any worn, damaged or illegible safety decals
at once. Refer to Safety Decals, “Important Safety In-
formation,” page 4, for correct decal placement. Ob-
tain new decals from your Great Plains dealer.
Marker Maintenance
Under normal conditions, the disk hub bearings need to be
repacked every 2 or 3 years. If the grease seal cap is dam-
aged or missing, disassemble and clean the hub. Repack
with grease and install a new seal or grease cap.
Storage
Store the drill where children do not play. If possible, store
the drill inside for longer life.
1. Clean the drill as necessary. Be sure the seed boxes
are cleaned completely before storing.
2. Adjust and oil all roller chains. Lubricate the drill at all
points indicated under Lubrication, this page.
3. Check all bolts, pins, fitting and hoses. Tighten, repair
or replace parts as needed.
4. Check all moving and soil-contact parts for wear or
damage. Make notes of any parts needing repair.
5. Use Great Plains touch-up paint to cover scratches,
chips and worn areas to prevent rust.
IMPORTANT: Be sure the seed-cup drive sprocket is
oiled before the drill is stored. Squirt oil onto the
square seed-cup shaft and move adjustment handle
to get the oil into the square.
