This invention reveals a corn harvester header comprising: multiple harvesting units placed adjacently among them, where each of said harvesting units has a central slot through where a maize plant is processed to separate the ears from the stalks; multiple crop divisors, each placed between two adjacent harvesting units; and multiple frontal devices, each place in front of and between two adjacent harvesting units; where each one of said multiple frontal devices comprise: a pair of guiding elements, where the guiding element is selected from a group of: chain or belt; two or more wheels; and a support; where the guiding element is placed around said two or more wheels; where one of the two or more wheels drives the spin of the guiding element, where the tangential speed of the guiding element is configured according to the distance between the plants in the crop; and where an opening greater that the harvesting slot is created.

A header for an agricultural vehicle includes: a header frame; at least two row dividers carried by the header frame and defining a gap therebetween; and a crop material saver disposed in the gap and including a pair of saver flaps, each of the saver flaps being positioned such that the saver flaps co-act as a one-way pass-through to allow crop material flow past the saver flaps in an admission direction and inhibit crop material flow past the saver flaps in an inhibited direction opposite the admission direction.

A row crop header for an agricultural machine harvesting a crop having stalks, such as corn. The row crop header includes a frame, a first crop row divider mounted to the frame, and a second crop row divider mounted to the frame and spaced from the first crop row divider to define a space therebetween. A row unit is disposed at the space, wherein the row unit includes a deck assembly defining a gap, the deck assembly including a compliant deck configured to adjust the gap based on contact with the stalks of the crop. The compliant deck includes a plurality of overlapping plates having edges defining the gap where the edges are configured to move responsively to varying diameters of stalks. Crops are separated from the stalks upon contact with the overlapping plates. A gathering chain moves the separated crops toward a collector.

A sugarcane harvester comprises a frame, a basecutter coupled to the frame for translation relative to the frame, a knockdown roller mounted for translation relative to the frame, and a synchronizer configured to translate the knockdown roller in unison with the basecutter so as to maintain a position of the knockdown roller relative to the basecutter upon translation of the basecutter relative to the frame.

A self-adjustable feeder for a sugarcane harvesting device having two vertical feeding rollers rotating in opposite directions, aligned side by side and horizontally moving, kept under traction one against the other by at least one actuator. The upper edges of both feeding rollers, besides being coupled to hydraulic engines rotating in opposite directions, are also hinged to a rear opening and closing structure, with a guiding system to change the distance between the vertical centers of the feeding rollers.

A deck plate extension for a row unit of an agricultural harvester. The deck plate extension configured to attach to the return side of the row unit side thereby preventing a kernel crop from dropping to the ground during harvesting. The deck plate extension is further provided with a kernel channel configured to direct the kernel crop along the return side of the row unit side to the harvest side of the row unit side. The deck plate extension may be provided as part of a deck plate of a row unit side or may be provided as a second plate added to the row unit side. The deck plate extension is configured to be added as original equipment and as a retrofit to existing row units.
