Raising/Lowering Planter
The planter mainframe raises and lowers independently
of the tongue.
• The planter may be fully raised at any time (and must
be raised for folding).
• The planter may be lowered onto its transport lock
channels at any time.
• The planter may be fully lowered, with lock channels
removed, only when unfolded.
Refer to Figure 22
The CFM “CLUTCH” switch positions are not shown
because they normally require no attention during lift or
lower. Lifting the planter automatically disengages the
entire drive system.
The “Fert.Pump” switch has no function YP1225 and
YP1625 planters as shipped by Great Plains because
the optional fertilizer system for these planters uses a
ground-drive pump that has no electrical control.
Leave or set the CFM Marker/Fold switch in “Marker”
position to prevent unintended folding.
Raising Planter
The planter may be raised at any time.
1. Set the CFM “Lift/Hitch” switch to Lift to enable the
lift cylinder circuit.
2. Move the Lift/Hitch circuit lever to extend the lift cylin-
ders.
3. Set the circuit to Neutral to hold the planter at lift.
The switch
may be left in the “Lift” position.
Crushing and Entrapment Hazard:
Rely on circuit neutral to hold the planter raised only for brief
periods, such as field turns and lock channel installation. Use
lock channels at all other times.
4. Install lock channels if raising for transport, parking,
storage, adjustments or maintenance.
Note: After every few hours of operation (or earlier, if un-
even lift is observed), re-phase the lift circuit. At a
lift operation, hold the circuit in Extend for
30 seconds.
FigureSpacer:
Note: If your planter has an aftermarket pumping system
compatible with the Intelli-ag system, the
“Fert.Pump” switch may require operator attention
during lift/lower.
