Fertilizer Box Clean-Out
After applying fertilizer, clean the box as soon as
possible. Fertilizers often contain corrosive chemicals.
Refer to Figure 40
With a small scoop or can, remove as much fertilizer as
possible from drill boxes.
Clean-out releases material across the entire length of a
box. Have collection equipment prepared.
Release all clean-out latches on the drill, and open
clean-out door. Leave door open until after washout.
Refer to Figure 41
Wash inside of fertilizer box with high pressure water.
Let drill boxes dry before closing clean-out doors.
Small Seeds Box Clean-Out
1.
Open box lid and scoop out as much seed as
possible.
2.
To recover remaining seed, place a collection tarp
under the small seeds tubes at the openers.
3.
Raise drill.
4.
Set seed rate handle to 100.
5.
Rotate calibration crank or end wheel until no seed
flows.
6.
If a vacuum cleaner is available, remove any residual
seed from top of meters.
Disc Maintenance
Coulter and opener disc blades wear in normal service,
becoming smaller in diameter. Periodically check blade
diameter, and replace when below the recommended
limits. Discs can also be dented by unusual field hazards,
or bent. Replace damaged blades immediately.
Opener Disc Replacement
Replace 15 in. (38.1 cm) opener discs when
re-positioning spacers no longer brings both blades into
the contact as recommended at “Disc Blade
Adjustments” on page 36.
Consult updated Parts Manual for latest disc, or disc
assembly part number.
Coulter Disc Replacement
Replace 17 in. (43.2 cm) coulter blades when adjusting
drill level becomes difficult. Two signs that blade
replacement is indicated are:
• Coulter height adjustments drill-wide are using the
lowest axle hole (page 32).
• Coulter blade diameter is close to, or below,
15 in. (38.1 cm).
See page 59 for replacement and alternate coulter
blades.
