Maintenance and Lubrication
Maintenance
Proper servicing and maintenance 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 any maintenance.
!
WARNING!
You may be severely injured or killed by being crushed from a
falling implement. Always have transport locks in place and
frame sufficiently blocked up when working on implement.
!
WARNING!
Escaping fluid under pressure can have sufficient pressure to
penetrate the skin. Check all hydraulic lines and fittings before
applying pressure. Fluid escaping from a very small hole can be
almost invisible. Use paper or cardboard, not body parts, and
wear heavy gloves to check for suspected leaks. If injured, seek
medical assistance from a doctor that is familiar with this type
of injury. Foreign fluids in the tissue must be surgically removed
within a few hours or gangrene will result.
1. Inspect hoppers for debris and clean if necessary.
2. Clean dirt and grease from chains and moving parts.
3. Lubricate planter at points listed under Lubrication,
page 24.
4. Check all bolts and replace worn parts on the planter.
Check that all safety decals and reflectors are legible.
Replace if damaged. Refer to Safety Decals, “Impor-
tant Safety Information,” page 4.
Finger Pickup Meter
To inspect and repair finger-pickup meters, remove meter
from hopper, then remove three 1/4-inch bolts (1) on the
meter baffle (2) to gain access to the finger mechanism.

Inspecting Meter Fingers
Inspect the brush for wear. The brush should cover at least
half of a finger tab. Replace brush after every 100 acres of
planter operation.
Clean chaff and debris from meter after every 50 hours of
planter operation. To clean meter, see Figure 5-3.
1. Remove cotter pin (1), cage nut (2) and adjusting nut
(3) from shaft.
2. Lift finger assembly (4) off shaft and clean. Replace
worn fingers and springs after 250 to 300 acres of row
operation. To remove a finger, lift finger out of slot.
When replacing a finger, place the springs so the open
side of the spring loop faces the inside of the spring
housing.
3. Inspect carrier plate (5) for seed indentations and
wear. Replace carrier plate when wear affects seeding
accuracy.
