Loading Liquid Fertilizer (Option)
If liquid fertilizer will not be applied, lock-up the fertilizer
ground drive (page 44), or disengage the chain on the
pump drive.
System Inspection
1.
Wear protective equipment suitable for the material
presently in or previously dispensed from the tank(s).
2. Remove the tank lid and inspect for:
- residual fertilizer incompatible with next use
- contaminants
- debris that might clog filters
- trapped animals, lost tools, etc.
3. If it is necessary to flush the tank, or remove debris
too large to flush, see “Tank Clean-Out” on
page 110.
4. Re-secure the lid.
5. At first use each season, and after extended use,
check the strainer mounted under the pump. Perform
any cleaning before loading fertilizer.
6. The standard screen size is 80 (Blue). Some orifice
selections (step 9) require changing the strainer.
Tank Loading
Refer to Figure 26, and
Figure 45 on page 56
Review the information below before commencing steps.
• Load chemicals immediately prior to use. Material
loaded too early may sediment or stratify, resulting in
uneven application or system plugging.
• The tank is designed to be loaded using the 2 inch
CAM quick-fill inlet ( ), located at the left front of the
implement. If for any reason you cannot use that inlet,
you can also load material via a ladder and tank top
hatch. The lid is threaded and unscrews. The smaller
cap center may be removed as well.
• Determine how to monitor tank fill level. A sight gauge
is provided on one side of the tank. If the day is bright,
or loading at night with a bright light available, it is
possible to see the fluid level through the
semi-translucent tank walls. Otherwise, it is necessary
to have an observer monitor through the tank hatch.
• Be familiar with the location of plumbing valves.
Common tasks require setting as many as three
planter valves. See page 56.
7. Consult the Seed and Fertilizer Rate manual
(411-020B) for rate setting details.
8. Set the Fertilizer drive sprockets and piston pump
rate adjuster per the Rate charts.
9. Install the recommended size orifice plate at each
active drop line (Seed Rate manual).

Agricultural Chemical Hazard:
Avoid contact with skin or eyes. Wear proper protective
equipment as required by chemical manufacturer. Avoid
prolonged breathing of chemical fumes. Wear respirator as
required by chemical manufacturer. Some chemicals will cause
serious burns, lung damage, and death. Seek medical
assistance immediately if an accident occurs. Know what to do
in case of accident.
Equipment Damage Risk:
Do not run the CDS-John Blue
®
pump when dry. Remove the
final pump drive chain if not applying fertilizer. Air rapidly
corrodes the pump. When not pumping, fill the pump with
clean water or RV antifreeze.
Equipment Damage and Plugging Risks:
Use only materials compatible with polyethylene and
polypropylene. Use only pre-mixed liquid fertilizer. The system
is not designed for dry fertilizer mixes. Granular fertilizer may
damage the pump and plug orifices.
Equipment Damage Risk:
Do not leave fertilizer standing. Load late. Pump it all. Clean
out the system. Fertilizer is usually extremely caustic, and can
damage the piston pump if left standing. Also protect the pump
from air. See “Liquid Fertilizer Clean-Out” on page 110.
Note: Is it not possible to use the planter pump to load
material, as it only pumps when the planter is in
motion and is only plumbed to pump to the boom.
If the fertilizer source has no pump, it needs to be
elevated above the tank for gravity fill.
