2-Point Planter with Lift Assist
 The electrical circuit must be connected to allow the
wings to lower completely after the planter is
unfolded.
M ake sure the low pressure return line from the fan is
connected to the tractor low pressure sump return before
folding or unfolding the planter. Operating the wing flex
circuit dumps oil (from the rod ends of the flex cylinders) into
the low pressure return circuit, so the low pressure return line
must be connected to the tractor.
