Liquid Fertilizer Operation (Option)
For planters with serial numbers (YP425A s/n B1008N-)
(YP625A s/n B1043Q-) (YP825A s/n B1014S-) the pump
is driven from the same ground drive that operates the
seed metering system.
For planters with serial numbers (YP425A s/n B1009N+)
(YP625A s/n B1044Q+) (YP825A s/n B1015S+)57
the pump is driven by ground wheel drive.
When the planter is lowered and in motion, the pump
operates, and fertilizer is applied based on fertilizer
transmission sprockets and pump adjuster setting.
Great Plains recommends checking with your local
agronomist, as soil conditions vary. Conditions in your
area may need less or more fertilizer than represented in
the charts. For in-furrow applications, do not exceed 12
gallons per acre in any case.
The liquid fertilizer system is designed to operate
(ideally) between 15 and 40 psi. Several system
elements affect system pressure, and need initial setup,
periodic maintenance, and adjustment when changing
seed rates.
These steps presume that fertilizer has been loaded
(and other setup items completed) per “Loading Liquid
Fertilizer (S/N+)” on page 29 and page 31 (and per the
Seed and Fertilizer Rate manual 401-651B).
Refer to Figure 132 on page 140 or Figure 133 on page 141
1.
Confirm Quick-Fill inlet valve Closed:
handle to planter left.
2. Set selector valve to Pump:
handle to planter rear.
3. Set tank discharge valves to Operate:
handles toward plumbing to selector valve.
4. If relief valve has not been previously adjusted,
perform initial setting per page 58.
Prime the fertilizer system before filling meter disks (to
avoid wasting seed, as it usually takes more than one
meter revolution to fill the boom).
5. Shut off the fan.
6. On suitable ground, lower the planter.
7. Pull forward until the fertilizer gauge registers
some back-pressure from the boom.
8. Open row slide gates and meter shutters.
9. Monitor the fertilizer gauge. Make relief valve
adjustments per page 58.
10. Mind the fertilizer tank levels while planting, both to:
a. confirm expected consumption rate, and;
b. avoid running the pump dry.
11. If residual fertilizer is not recovered at end of
planting, apply it to the last field planted. Turn fan off
to prevent metering seed or remove a meter drive
system chain. Optionally lock up rows to reduce row
unit wear (page 77).
12. Clean out fertilizer system per page 99.
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 accident occurs. Know what to do in
case of accident.
Equipment Damage/Material Misapplication Risks:
Do not run pump dry. With all drive chains in place, the pump
always runs when the planter is lowered and in motion. Air
rapidly damages a pump. Keep fluid in pump at all times.
Disconnect a chain when not applying fertilizer.
If fertilizer is exhausted prematurely, reload fertilizer
immediately. If fertilizer is not available, load clean water,
continue planting with pump operating (to flush system), and
disconnect pump drive before water is exhausted (to keep
pump wet).
