Optional Piston Pump
If the machine is equipped with the piston pump option,
the rate of liquid fertilizer application is determined by the
piston pump settings.
To adjust delivery rate, loosen the 3/8" lock nut that
secured the arm with the pointer and rotate the scale
flange until the pointer is over the desired scale setting.
The adjustment wrench will facilitate rotation of the scale
flange. Tighten the 3/8" lock nut being careful not to over
tighten.
Cleaning
The tanks and all hoses are made of sturdy plastic and
rubber to resist corrosion. However, the tanks, hoses and
metering pump should be thoroughly cleaned with water
at the end of the planting season or prior to an extended
period of non-use. Do not allow fertilizer to crystallize due
to cold temperature or evaporation.
On machines equipped with the piston pump, the strainer
located between the piston pump and ball valve should
be taken apart and cleaned daily. Remove the end cap
to clean the screen.
Piston Pump Storage
KEEP AIR OUT OF THE PUMP! This is the only way
to prevent corrosion. Even for short periods of storage,

the entrance of air into the pump will cause RAPID AND
SEVERE CORROSION.
Overnight Storage
Suspension Fertilizer must be flushed from the pump for
ANY storage period.
Winter Storage
1. Flush pump thoroughly with 5 to 10 gallons of
fresh water and circulate until all corrosive salts are
dissolved in the pump.
2. With the pump set on 10, draw in a mixture of half
diesel fuel and half 10 weight oil until the discharge is
clean. Then plug inlet and outle.t

The above chart is for planters equipped with ground drive
wheels that have 7.60 x 15 tires, 26 tooth drive sprocket,
and a 22 tooth driven. This chart is based on average
wheel slippage and liquid viscosities. This chart is also
based on standard pump sprockets of 30 tooth drive and
16 tooth driven. Other sprockets are available.
Measure and weigh one gallon of actual fertilizer solution
to determine exact application rates. This chart was
calculated based on a solution weighing 10 pounds per
gallon.
IMPORTANT: Fertilizer application rates can vary
from the above chart. To prevent application
miscalculation, make field checks to be
sure fertilizer is being applied to all rows
at the desired rate.
NOTE: Flow to all rows should be checked periodically.
If one or more lines are plugged, the desired rate
will be delivered to the remaining rows keeping
total application rate at desired rate.
How to check the exact number of gallons fertilizer
attachment will actually deliver on 30" row spacing,
proceed as follows:
