John Blue Ground Drive Pump
Refer to Figure 68
With newer Type 2 fertilizer systems, the pumps
are
driven by a ground contact wheel . Fertilizer rate is
independent of seed rate. Fertilizer coarse rate is set by
a driving sprocket
on the ground drive assembly, and
fine rate is adjusted at the setting hub (dial) on the
pump.
Equipment Damage/Material Loss Risks:
The ground drive contact wheel and chain system will operate
whenever the planter is lowered and in motion. If planting
without fertilizing, the pump must not be allowed to run dry.
Disconnect the chain or remove a sprocket.
Note: When a Type 3 fertilizer system is installed, the
pump is mounted at the source (not on the planter),
usually on a tank cart.
For sprocket and dial settings, refer to the Seed Rate
manual.
