Liquid fertilizer distribution systems
a
are optional on the
YP40 planter and are optimized for use with the optional
on-board 2x200 gallon tanks and/or the Great Plains
PFC1600 or PFC2000 tank carts.
If installed, there are several points of fertilizer setup
and/or adjustment:
1. Pump setting dial or sprockets
Basic pumping rate is adjusted at pumps.
For the cart-mounted pump and center section
ground-drive pump, a dial on the pump sets rate.
Refer to the Seed Rate manual and the tank cart

Orifice plate sizes are chosen to assure consistent
pressure at all nozzles. Refer to the Seed Rate
manual.
3. Relief valve setting
See “Fertilizer Relief Valve” on page 64.
4. Inlets
Both Type 2 (2-section, single inlet) and Type 3
(3-section, 3-inlet) systems have quick-connect inlets
and shutoff valves at the back of the planter. See
page 23 for hook-up details.
5. Strainer setup
The optional ground drive pump includes a strainer.
The mesh screen size must be compatible with the
orifice plates in the distribution system. Refer to the
Seed Rate manual.
Great Plains recommends checking with your local
agronomist as soil conditions vary. Soil conditions in your
area may need less or more fertilizer than represented in
these charts. In furrow, do not exceed 12 gallons per
acre in any case.
The liquid fertilizer system is designed to operate
(ideally) between 15 and 40 psi, but in no case more
than 65 psi. Several system elements affect system
pressure, and need initial setup, periodic maintenance,
and adjustment when changing fertilizer rates.
a. Type 2, Type 3, or both, with or without planter-mounted ground drive pumps for Type 2. See page 23 for details.
