Liquid Fertilizer Clean-Out
With proper attention to maintenance, end of day
clean-out, end of season clean-out and winterization,
you can substantially increase the life and reliability of
your fertilizer system. Protect the pump, clean the tanks,
strainers, lines and nozzles, and you can avoid costly
and time-consuming repairs at the next season.
Fertilizers are usually highly corrosive to metals other
than stainless steel. Suspension fertilizers can clog
system components in storage.
Flush entire system with clean water. Do this at the field
last treated, or other location compliant with chemical
supplier clean-up instructions.
14. Remove end caps from booms and flush booms out
with water. Drain and replace end caps.
15. Remove strainer and drain it out. Drain all lines and
tanks completely to prevent freezing damage.
16. Remove drop line nozzles. Clean orifice plates.
17. Cap or plug inlet line to tractor.
18. Flush pump per pump supplier manual. Fill pump
with RV antifreeze and cap off.
19. Wash all spilled fertilizer off the planter.
Tank Clean-Out
Refer to Figure 132 on page 140 or Figure 133 on page 141
1.
If the pump has already been filled with RV
antifreeze for storage, set the main selector valve
to Off or Quick-Fill to prevent draining pump.
Refer to Figure 109
2.
Move the planter to a location suitable for draining
material last applied from the tank, or where the
drainage can be collected. A site with access to rinse
water is ideal.
3. Open the tank lids. Observe the quantity of material
present. Check for build-up, sedimentation and
foreign matter, particularly any objects large enough
to clog the drain.
4. On a two tank system, clean one tank at a time.
5. Slowly operate the tank discharge line valve
handle to open the tank to the drain elbow
(“FLOW” legend toward drain elbow).
6. Power-wash the inside of the tank from above.
7. When the tank is clean and drained, set the
discharge valve to Off or Fill/Pump.
8. Close the tank lid.
