Abstract

A harness adapter is disposed between the seed monitor logic circuitry and the individual row unit seed detectors upon conversion of a planter for operation of only a portion of its planting units. The adapter provides a continuous series of connections from the detectors associated with operative row units while electrically isolating the detectors on the non-operative row units.

Claims

1. In a multi-row planter having a plurality of seed dispenser equipped row units, a portion of said plurality of units being operatively disconnectable from said planter, a remaining portion of said row units being operative, a plurality of seed detecting circuit means respectively associated with the dispensers of the plurality of row units, readout display means, logic circuit means coupled between said plurality of seed detecting circuit means and said readout display means and responsive to output signals from said seed detecting circuit means for energizing said readout display means to identify which of said plurality of dispensers is operating improperly, wherein the improvement comprises:

a quick attachable adapter, usable when said portion of said dispenser equipped row units are disconnected, that is insertable between said plurality of seed detecting circuit means and said logic circuit means and connecting the seed detecting circuit means associated with said remaining portion of said row units to said logic circuit means while isolating the seed detecting circuit means associated with the disconnected units, said adapter also connecting said logic circuit means in a continuous series of connections to provide a display for said remaining portion of said seed dispenser row units.

2. The planter of claim 1, in which said portion includes individual dispenser equipped row units that are generally spaced between adjacent dispenser equipped units of said remaining portion of units.

3. The planter of claim 2, in which said individual units of said portion are positioned rearwardly of said adjacent units of said remaining portion.

4. The planter of claim 3, in which said portion of said dispenser equipped units totals 5 and said remaining portion totals 8 for a plurality of dispenser equipped units of 13.
