31 Maintenance and Lubrication
Maintenance
1. After using your drill for several hours, check
all bolts to be sure they are tight.
2. After using or transporting your drill for sever-
al hours, check all wheel lug bolts and nuts.
Be sure they are tight.
3. Disk scrapers should be kept properly adjust-
ed.
4. Always maintain the proper air pressure in the
gauge wheel and transport tires. For proper
air pressure refer to “Tire Inflation Chart,”
page 36.
5. Before the drill is transported and regularly
during normal operation, check the hitch safe-
ty chain. Make sure the chain is properly at-
tached to both the drill and the tractor draw
bar. Inspect the chain and hardware for wear
or other damage. Replace immediately if
needed.
6. After a period of time, the drill boxes may
gradually become out of line with each other.
To correct this condition, refer to " Box Align-
ment Adjustments," page 23.
Lubrication
1. After using your drill for several hours, check
all bolts to be sure they are tight.
2. Listed below are the items you need to lubri-
cate every 20 to 25 hours of operation:
a. Marker body hinges.
b. Jack shaft bearings.
c. Feeder cup drive sprocket bearings.
d. Post top roller shaft.
e. Box post lower spindles and cross tubes
on main frame.
f. Telescoping axle tube lower roller be-
tween transport tires.
Maintenance and Lubrication
3. Listed below are the items you need to lubri-
cate before storing the drill:
a. Clean and oil all roller chains.
b. Seed cup drive sprocket should be oiled
in its square bore. Move seed cup adjust-
ment lever away from the sprocket as far
as possible in order to get the oil back into
the square.
c. Oil knob adjustment trunnion lower pivot
tube on press wheels.
Note: 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.
Storage
1. Clean the drill as necessary. Be sure that the
seed boxes, fertilizer box and all feed systems
are completely cleaned out before storing.
2. Lube chain and adjust all roller chains.
3. Lubricate all fittings as indicated in “Mainte-
nance & Lubrication” on page 31.
4. When storing in transport position, use all
locking devices as described under "Trans-
porting," page 26 and "Operating Proce-
dures," page 24.
5. Apply a light coat of grease to all exposed hy-
draulic cylinder rods.
6. Seed cup drive sprocket hub should be oiled
in its square bore. Squirt oil on to the square
seed cup shaft and move seed cup adjust-
ment lever back and forth in order to get the oil
back into the square. This is most important
before putting the drill in storage.
7. Store the drill inside if possible. Inside storage
will reduce maintenance and make for a long-
er drill life.
