A hybrid flute for a stalk roll may be configured with a sharp edge positioned between a first blunt edge and a second blunt edge along a length of the flute edge. The flute edge may extend radially outward from a main cylinder of the stalk roll. The flute edge may be engaged with a radius at the base of the flute edge, and a flute base may extend from the radius. A plurality of flute bases positioned adjacent to one another may be configured to form a main cylinder for the stalk roll.

A crop stripper header includes a crop stripper rotor with a central core and a plurality of stripper teeth projecting radially outwardly from the central core. The central core is supported for rotation by first and second end hubs. A dynamic balancing system is provided in each of the end hubs. The dynamic balancing system includes a plurality of steel balls or other suitable weights contained in hollow cavities in the end hubs. The balls are freely moveable within the hollow cavities during rotation of the rotor so that the weights of the balls are distributed to positions within the hollow cavities that tend to neutralize any imbalance in the rotor during operation.

Some crops, such as soybeans, grow close to the ground, having a low canopy relative to that of weeds growing interspersed in the crop. A farm implement removes weed growth above the crop canopy. The implement has a chassis with at least three wheels connected to the chassis, a cutting mechanism, mounted at a front end of the chassis, a means for collecting weed growth cut by the cutting mechanism, mounted on the chassis, means for generating and selectively applying rotational torque to at least one of the at least three wheels and means for a user to guide the chassis down the rows in which the crop is grown.

A crop harvesting header having a frame mounted on a propulsion vehicle has a cutter bar carrying a sickle knife and a draper transport. The draper is guided at its front edge by a longitudinally extending rail mounted on the frame for movement therewith. The cutter bar is mounted on the frame at spaced positions by spring blades attached to a fixed beam at the rear which allow up and down flexing movement of the cutter bar relative to the draper engagement member. At the center discharge the cutter bar is carried on shorter blades which are carried on a beam in front of the front draper roller. The small amount of flexing of the cutter bar combines with a balanced three piece header frame to provide effective ground following.

A system for removing parts from plants rooted in an agricultural field while leaving other parts of the plants rooted in the agricultural field may include a harvester apparatus with an intake throat formed by structures such as the combination of an infeed head and infeed conveyor, a pair of stripping assemblies including stripping belts, or stripping assemblies including stripping members such as chains.

A harvesting system for harvesting stalky plants is mountable on a power unit such as an agricultural or construction tractor having hydraulic power and/or a power takeoff (PTO). The system includes at least a reel-based harvesting head configured to cut off at least the tops of the plants and to transport the cut plants laterally of the harvesting system without threshing or otherwise processing the plants. The harvesting head may be mounted on, for example, an upper lift arm assembly or a three-point hitch mechanism of the power unit. If the harvesting head is mounted on the upper lift arm assembly of an agricultural tractor, a second harvesting head may be mountable on the tractor's three-point hitch mechanism beneath the first harvesting head for cutting stalks near their base, gathering the cut stalks, and windrowing the cut stalks behind the second harvesting head.

A stalk roll having twelve flutes extending radially from the main cylinder along the length of the main cylinder. Within the row unit opposing stalk rolls cooperate to engage and capture the corn stalk, thereafter, controlling and processing the corn stalk. The flutes may be configured with differing edges to facilitate control and movement of the stalk to the point of ear separation within the row unit. The flutes may be configured such that opposing compressive forces acting on the exterior of the stalk at approximately 180 of separation operate to implode the stalk while sharp edges on the flutes operate to cut the stalk into small segments which are deposited on the ground for decomposition.
