A harvester includes a main frame, first side frame, and a second side frame. The first and second side frames are rotatable about the main frame between a deployed position and a stowed position. A first crop divider is rotatable with respect to the first side frame to change an angle between the first crop divider and the ground. A first biasing member biases the first crop divider into the raised position. A second crop divider is rotatable with respect to the second side frame to change an angle between the second crop divider and the ground. A second biasing member biases the second crop divider into the raised position. During movement of the first and second side frames into the stowed position, the first and second crop dividers are moved into the lowered position against the biasing force of the respective biasing member.

Method for imaging a corn ear having an outer surface, the method implementing an imaging module having a field of view that enables an image of the outer surface of the corn ear to be acquired, the method comprising the step consisting in dropping the corn ear within the field of view of the imaging module and acquiring an image of the outer surface of the corn ear while the corn ear drops within the field of view of the imaging module.

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.

Differential speed stalk rolls mountable to a row unit of a row crop head. A first stalk roll body has an outer peripheral speed less than the outer peripheral speed of a second stalk roll body in lateral spaced relation. At least one of the first and second bodies includes a knife defining a knife plane normal to the axis of rotation of the first or second stalk roll. The stalk roll bodies may have modular and interchangeable body segments of different configurations.

The invention provides a device (10) for acquiring images of a plant, which device comprises: i) a first structure (60) defining a cavity (33) for receiving a portion to be imaged of the plant, the cavity presenting a longitudinal axis (13) and an opening (65) at one of its ends, the cavity being defined by at least one transparent wall forming a window (12) for observing the portion to be imaged; ii) a second structure (61) extending around the window (12) and mounted to move in translation along the longitudinal axis (13) relative to the first structure, and comprising: hollow reflective optics (11, 19) extending around the window and including a reflecting surface (19) directed towards the longitudinal axis; and a plurality of image sensors (18) regularly distributed around the window (12), the field of view (77) of each sensor including at least a portion of the reflective optics so as to capture images of the portion of the plant that is surrounded by the window, which images are reflected by the reflective optics; and. iii) an actuator (64) for driving the second structure to move relative to the first structure along the longitudinal axis.

An agricultural vehicle including a frame, a prime mover supported by the frame, and a header connected to the frame. The header includes at least one drive line, at least one transmission, at least one rotating cross shaft, and at least one gearbox operably connected to the at least one rotating cross shaft. The at least one gearbox includes a housing connected to the header and configured for housing a working fluid. The housing has an inlet, an outlet, and an end. The at least one gearbox also includes a gear train housed within the housing and an auxiliary sump connected to the end of the housing and fluidly coupled to the inlet and the outlet of the housing such that the working fluid circulates through the housing and the auxiliary sump.

In one aspect, a system for operating an agricultural harvester may include a sensor assembly having a base member pivotably coupled to a first row divider of the harvester. The sensor assembly may also include first and second arms extending outwardly from the base member along opposite sides of a centerline of the first row divider. The system may further include a controller communicatively coupled to the sensor assembly. The controller may be configured to monitor the distance between the first and second arms based on measurement signals received from the sensor assembly. Furthermore, the controller may be further configured to switch the harvester from a first operating mode to a second operating mode when it is determined that the monitored distance has exceeded a predetermined distance threshold.

An agricultural vehicle including a chassis, at least one power take off member, and a folding header operably coupled to the agricultural vehicle and supported by the chassis. The folding header includes a center section operably coupled to the chassis of the agricultural vehicle. The center section includes a pair of lateral ends and at least one drive assembly operably coupled to the at least one power take off member of the agricultural vehicle. The folding header also includes at least one additional section pivotally coupled to one of the lateral ends of the center section and operably coupled to the at least one drive assembly. The at least one additional section is selectively pivotable between an operational position and a nonoperational position. The center section is configured to harvest a crop material in both of the operational position and nonoperational position of the at least one additional section.

A stalk roll mountable to a header of an agricultural combine for rotation about a rotation axis during processing of plant stalks has an annular drum with detachable blades. The stack roll has a plurality of circumferentially spaced flutes extending in an axial direction of the rotation axis of the drum and projecting radially outwardly from the drum. The flutes define mounting surfaces along lengths of the flutes. A plurality of blades are attachable to the drum with multiple of the plurality of blades being attachable to the mounting surface of a common one of the flutes. Mounting hardware is configured to removably connect the blades to the mounting surfaces of the flutes.
