Fertilizer Systems Overview
The YP4025A-48TR20 supports one or two optional
fertilizer boom systems:
•
one or two Type 2 single-section booms, typically
used with on-board tanks, trailing SML tank cart, or a
user-provisioned trailing cart, supplied by an optional
product- or cart-mounted hydraulic pump system;
•
a Type 3 three-section boom, typically used with a
user-provisioned trailing cart, supplied by a pump
and manifold on the cart.
Use only pre-mixed liquid fertilizer. Do not use dry
fertilizer added to water in the tank.
Agricultural Chemical Hazards:
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 accident occurs. Know what to do in
case of an accident.
If the fertilizer product is at any risk of precipitation,
stratification or sedimentation, load it shortly before
application. Although the on-board and SML tanks
include bypass return ports, the flow through these lines
is too low to act as agitation (and may even be shut off).
S
ystem Plugging Risk:
Do not allow fertilizer to remain in the tanks for extended
periods or settling of material and system plugging will occur.
The next four pages cover plumbing diagrams and
system component identification for the available
on-board system and the available SML cart system.
Operations are described on page 59.
The “Fert.Pump” switch
on the Clutch Folding Module is not used with any
presently supported Great Plains tank, pump and
boom systems. It might be used to control a clutch
on a user-provisioned system that has a
solenoid-operated clutch.
