When roller chains remain unused for several days, mois-
ture in the air will accumulate on the chain, causing the
chain to rust. This can, and will, become serious enough in
time to cause the chain joints to become stiff, restricting
their normal free movement. While very difficult to detect,
this stiffness can encourage the chains to operate abnor-
mally and disturb the smooth rotation of important meter
components, causing deterioration in performance.
If the planter is not used for several days, or if oil has been
removed from chains, etc. while cleaning the planter thor-
oughly lubricate chains with multipurpose chain lube.
NOTE: Do not use chain lube or any other heavy petro-
leum base lubricant that may cause a buildup of dust or
dirt in the sprocket or gear teeth.
Turn the meter drive shaft by hand to be sure the drive
shaft and seed meter are free to turn. Rotate forward only,
as assemblies are not designed to rotate in reverse.
Be certain all adjustments are made for the planting con-
ditions to be encountered.
Service at the End of the Season
When planting is complete clean the seed and chemical
hoppers. Remove all dirt, debris, chemicals, and fertilizer
from the planter that may hold moisture and cause
corrosion.
Use spray paint to cover scratches, chips, and worn areas
on the planter to protect the metal.
Lubricate the planter as outlined in Lubrication. Pay care-
ful attention to the lubrication of the chains to help prevent
rusting.
Inspect the planter for worn or damaged parts. Make re-
pairs and service during the off season to reduce down
time in the field.
Place the 1 X 12 closing wheel handle in the middle slot to
relieve the tension on the closing wheels. Move opener
adjustment bar on heavy and medium down pressure
spring packages to hole A, refer to Figure 4-7 on page 26.
Remove the finger pickup meters from the hoppers. Dis-
assemble the meters and inspect them for wear. Make
any repairs required at this time. Blow excessive debris
from the meter. Wash the meters with mild soap and wa-
ter. Dry the meters and spray a light coat of rust inhibitor
on the meters. Reassemble and store in a dry place.
Thoroughly flush liquid herbicide system with clean water.
Disconnect from tractor and completely drain all lines and
components to prevent damage from freezing.
Store the planter in a clean, dry place with all tires out of
the sun. A sheltering structure is best for overall protec-
tion, but a high quality tarp would suffice.
