A corn harvester includes a first stalk roll having a plurality of first blades circumferentially spaced apart by a first angle. A second stalk roll has a plurality of second blades circumferentially spaced apart by a second angle. The first and second stalk rolls are rotatable about parallel first and second axes that are separated by a centerline therebetween. In an operational state when a tip of one first blade is aligned with the centerline, a tip of one second blade is angularly offset from the centerline by a third angle. The third angle is less than 45% of the second angle. The one first blade forms a cross section perpendicular to the first axis having an altitude extending from the tip toward the first axis along a first blade altitude. The cross section of the one first blade is asymmetric about the first blade altitude.

A method for producing 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 a combine harvester, 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.

A stalk roller assembly for an agricultural system includes a stalk roller having a hollow shaft. The hollow shaft has a first end having a first shape, such that the first end engages a guide element. Furthermore, the hollow shaft has a second end having a second shape that engages a drive shaft, such that the first shape is different than the second shape. In addition, the hollow shaft is formed from a single piece of material.

Chopping drum (10) for a field chopper, having a drum body (11), having a blade carrier (12) and having a plurality of blades (13) which are fastened to the blade carrier (12), each blade (13) being fastened to the blade carrier (12) via at least two fasteners (14) which extend through a fastening section (15) of the respective blade (13) into the blade carrier (12), and the fasteners (14) penetrating the fastening section (15) of the respective blade (13) at an angle of between 40 and 70.

A corn creamer may include a creamer base. A rotatable sleeve drive shall may be carried by the creamer base. A creamer sleeve may he drivingly engaged for rotation by the sleeve drive shaft. The creamer sleeve may have a sleeve wall and a sleeve interior formed by the sleeve wall. At least one creamer blade assembly may include at least one blade shaft carried by the sleeve wall of the creamer sleeve. At least one creamer blade may be carried by the at least one blade shaft in the sleeve interior of the creamer sleeve. In some, applications, a hand drill may be coupled to the sleeve drive shaft to rotate the sleeve drive shaft as an ear of corn is inserted into the rotating creamer sleeve. The at least one creamer blade of the at least one creamer blade assembly may contact the corn kernels on the ear of corn to remove the corn kernels typically for preparation of creamed corn.
