Tank Field Operation
Field Start-Up
These steps presume that all implement and cart setup
items are completed.
1. Position implement at start of field to be planted.
Raise and unfold the implement.
2. Open the inlet valve on the implement.
3. Open the outlet valve on the cart.
4. Open the discharge valve on the cart.
5. Check for leaks.
6. Prime the pump
a
:
Rotate the ground drive wheel (top forward) to oper-
ate the pump until material appears at the row drop
lines.
7. If using an electrically activated pump integrated with
the seed monitor, set the “Fert.Pump” switch (on the
switch under the console) to “ON”.
No other actions are usually required. Using a ground-
drive pump on the implement, material application starts
automatically when the implement is lowered and in
motion.
Planting
Liquid fertilizer systems on Great Plains implements are
generally not integrated with seed monitor electronics.
The tractor operator must visually monitor and periodi-
cally check tank condition.
Mind the boom manifold gauge. Investigate any periods
when the gauge is reading zero. Generally, the tank sight
gauge will not be visible from the tractor cab. The mani-
fold gauge may be the only indication of a material issue.
Check the material level in the tank at every opportunity.
Refill as needed to avoid pumping dry.
Material Run-Out
If the entire supply of material is consumed before plant-
ing is complete, disconnect the ground drive pump (see
implement Operator and/or Seed Rate manuals for
steps to disable a pump, typically removing a sprocket or
chain).
Null4:
a. For a pump other than a Great Plains ground drive, consult the pump or system documentation for stationary operation.
Note: Pump Priming:
The standard Great Plains ground-drive piston
pump is lower than the tank when the implement
is lowered for planting. Any amount of air in the
fertilizer lines is quickly pumped out.
If you are using another pump, such as a tractor-
mounted pump, or a pump that does not have pos-
itive displacement. The pump may have some dif-
ficulty with air in the lines. Refilling the tank to
pump installation height usually aids in priming.
Equipment Damage Risk:
Avoid dry pumping. Pumps, such as the CDS-John Blue pump
supplied by Great Plains, can be damaged if operated without
working fluid to pump.
