Maintenance
Proper servicing and adjustment is the key to the long
life of any farm implement. With careful and systematic
inspection, you can avoid costly maintenance, time and
repair.
1. After using your drill for several hours, check all
bolts to be sure they are tight.
2. Adjust idlers to remove excess slack from chains.
Clean and use chain lube on all roller chains as
needed.
3. Feed cup drive sprocket should be oiled in its square
bore. Move feed cup adjustment lever away from
the sprocket as far as possible in order to get the oil
back into the square.
5. Always maintain the proper air pressure in the rib
implement tires.
6. Disk scrapers should be kept properly adjusted.
7. Replace any worn, damaged or illegible safety de-
cals by obtaining new decals from your Great Plains
Dealer.
Marker Maintenance
Breakaway Protection. The marker arm is attached to
the marker body with a 3/8-inch, grade 2 shear bolt. If it
breaks, replace the shear bolt with a grade 2 bolt. The
bolt is Great Plains part number 802-253C.
Disk Bearings. Normally, the disk hub bearings need to
be repacked every 2 or 3 years. If the grease seal cap is
damaged or missing, disassemble and clean the hub.
Repack with grease and install a new seal or grease cap.
Storage
1. Clean the drill as necessary. Be sure that the bean
boxes are completely cleaned before storing.
2. Lubricate and adjust all roller chains.
3. Lubricate all pivots as indicated in the following Illus-
trations.
4. Feed cup drive sprocket hub should be oiled in its
square bore. Squirt oil on to the square feed cup
shaft and move feed cup adjustment lever back and
forth in order to get the oil back into the square. This
is most important before putting the drill in storage.
5. Disconnect seed hoses from parallel linkage open-
ers. Permanent elongation and premature cracking
of hoses may occur if stored connected
6. Store the drill inside if possible for longer drill life.
