Combine harvesters are provided for use in harvesting seed corn from corn plants in fields. In connection therewith, a method for producing such seed corn from the corn plants, for use in growing subsequent corn plants, includes measuring a moisture content of corn kernels on ears of the corn plants in the field and removing, by one of the combine harvesters, the ears of corn from the corn plants when the moisture content satisfies a threshold moisture content. The method then includes separating the corn kernels from cobs of the ears of corn onboard the combine harvester and collecting the separated corn kernels for use as seed corn, whereby one or more subsequent corn plants can be grown from the collected corn kernels.

There is disclosed a power-assisted corn kernel remover comprising a rigid frame supporting an annular corn kernel cutter. A powered mechanism mounted above the cutter activates a piston downward to push shucked ears of fresh corn onto the cutter. The cutter is sized and has a sharp cutting edge that severs the corn kernels from the cob as the ear descends. The cob is pushed downward through a passage to a disposal bin, while the kernels are captured by a basket surrounding the cutter. The cutter is formed of spring steel and is loosely held within the frame to allow for some expansion due to different sizes of corncobs. The powered mechanism may be a pneumatic piston and cylinder assembly supplied with compressed air and having a control mechanism that permits partial activation.
