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.
4. Always maintain the proper air pressure in the rib
implement tires.
5. Disk scrapers should be kept properly adjusted.
6. Replace any worn, damaged or illegible safety de-
cals by obtaining new decals from your Great Plains
Dealer.
Fertilizer Unit
It is recommended that the fertilizer unit be thoroughly
cleaned every two or three days during operating sea-
son and before putting the drill in storage for an extend-
ed period of time.
Storage
1. Clean the drill as necessary. Be sure that the seed
boxes are completely cleaned before storing.
2. Lubricate and adjust all roller chains.
3. Lubricate all pivots as indicated in the following Illus-
trations.
NOTE: Fertilizer build up on the rotor will affect the
fertilizer application rate. Drop fertilizer tray doors by
releasing latches on back of tray. Using a high-pres-
sure water system, thoroughly clean the fertilizer
tray, gate openings, and rotor. Rotate end sprocket
to ensure cleaning the entire fertilizer metering star
at each drop location.
