A header includes: a header frame; a cutter carried by the header frame; a roll disposed rearwardly of the cutter and configured to convey cut crop material rearwardly in a crop flow stream; a swath gate coupled to the header frame and movable between a spreading position and a converging position; a spreader coupled to the swath gate and configured to laterally spread the crop flow stream as the crop flow stream flows across the spreader; and a converger coupled to the swath gate and configured to converge the crop flow stream toward a centerline of the swath gate as the crop flow stream flows across the converger. The spreader and the converger are configured to not be in the crop flow stream at the same time, depending on the position of the swath gate.

A mower which may include: an engine for driving at least first and second cutting blades, wherein the first and second cutting blades are located in first and second cutting chambers of the cutter deck structure, wherein the cutter deck structure may include an inclined surface in the first cutting chamber so that at least part of the inclined surface is located closer to the trim side of the cutter deck structure than is any cutting blade rotational axis, the inclined surface extending downwardly from an upper surface of the cutter deck structure toward at least the trim side of the cutter deck structure, wherein the inclined surface slopes downwardly from the upper surface in a direction away from the side-discharge opening; wherein the inclined surface is configured to help provide a high pressure zone within a rear portion of the cutter deck structure and a low pressure zone proximate the trim side of the cutter deck structure for helping vegetation to be cut to be pulled into the first cutting chamber.

The present invention refers to vertical roller devices to assist the supply of stems to sugar cane harvester, which are installed on the front side (A) of the harvester, fastened to the row dividers and which work in pairs, with elements on the right and on the left, which can consist of one or more pairs. The devices are designed to continuously propel and to guide the sugar cane stems to the inside of the harvester. The devices with vertical rollers (6) are formed by hydraulic motors (6a), finned cylinders (6b), upper fixing support members (6c) and lower fixing support members (6d). In the case of a single row, the devices are installed in the harvesters in accordance with to (B) and, in the case of two or more rows, in accordance with (C) on the inner faces (2) of the row dividers. The distance between the elements of the respective pairs decreases from the front to the inside of the harvester, guaranteeing continuous directional pressure on the cane mass as the vertical roller devices convey the cut canes towards the inside of the harvester, eliminating the jamming of stems, and maintaining a constant flow in the front part of the harvester and a consequent increase in harvest yield.

A harvesting head yield monitor comprises two sensing elements (328, 330) respectively disposed in two adjacent row unit covers (114). A driver circuit (400) drives one of these sensing elements (328) to produce a high radio frequency signal. The other sensing element (330) receives the signal. A signal conditioning circuit (402) receives the signal from the other sensing element. A controller (404) coupled to the signal conditioning circuit converts the received signal into a signal that indicates the crop yield of the row unit that is disposed underneath the two adjacent row unit covers.

A turfgrass brushing assembly and system is disclosed. A frame assembly may be configured to removably couple to a mower cutting unit, and may have a cross member and two opposing side plates. Each side plate may include an array of holes and a pivot coupling configured to pivotally couple the turfgrass brushing assembly to the mower cutting unit. Each side plate may be releasably coupled to a different end of the cross member through at least one hole of the array of holes. A brush holder assembly may be adjustably coupled to the frame assembly, and may have a brush block coupling configured to couple to a brush. An angle adjustment assembly may be coupled to the brush holder assembly and the cross member. The angle adjustment assembly may pivot to adjust a relative angle of the brush holder assembly with respect to the frame assembly.

A crop cutting device including a crop guiding surface including parallel slots. A row of knives pivotally mounted below the guiding surface is pivotable between a retracted inoperative position in which it is located below the guiding surface and an extended operative position, wherein the knives project above the guiding surface. An actuating mechanism includes movable operating members. Each operating member is associated with a respective knife and is movable from a first position in which the knife is in its retracted position to a second position in which the knife is in its extended position. Further, there is included a lifting mechanism for raising at least a part of each knife above the guiding surface, while the operating members are in their first position.
