Center-Fill Planters
On ground drive models YP1220, YP1225#55,
YP1225A#55, YP1625#55, YP1625A#55, YP1630F,
3PYP#55 and 3PYPA#55, the PTO system drives one
motor, the fan supplying air for seed delivery and meter
pressurization. The air ratio is servo vane controlled by
the seed monitor. The vane needs to be active for
accurate flow control adjustments.
Adjustment Steps:
1.
Hitch the tractor to be used, and install the PTO
pump. Raise the planter. Unfold the planter.
Refer to Figure 10
2.
Release the lock disc counter-clockwise to
release the knob . Turn the knob fully clockwise to
shut off flow to the motors.
Entanglement and Crushing Hazard:
Use extreme caution in the hitch area when the PTO is
operating.
3. Start the tractor, and seed monitor. Bring the PTO
up to expected field rpm (which is often not the full
1000 rpm).
4. With one person observing the fan rpm readout on
the seed monitor, turn the knob
counter-clockwise until the fan is at the rpm
recommended for this planter configuration, crop,
population and intended field speed.
Secure the knob at this setting with the lock disc.
5. Monitor fan rpm when planting. If it is lower than
during flow setup, perform the setup steps again,
and set the valve for a higher rpm.
