Feederhouse gearboxes are provided for installation on combine harvesters. In embodiments, the feederhouse gearbox includes a gearbox housing, an output shaft rotatable about an output axis, and a primary drive input. The primary drive input is mechanically linked to an engine of the combine harvester when the feederhouse gearbox is installed thereon. A reverser drive input is mechanically linked to a reverser motor of the combine harvester when the feederhouse gearbox is installed on the combine harvester. The feederhouse gearbox further includes a selector mechanism within the gearbox housing and movable between a primary drive position and a reverser drive position, a primary gear train transmitting rotation from the primary drive input to the output shaft when the selector mechanism is in the primary drive position, and a reverser worm drive transmitting rotation from the reverser drive input to the output shaft when the selector mechanism is in the reverser drive position.

This summary of the invention refers to the development of a ramp (flexible front guard) that is mounted to a cutting platform to prevent grain loss and dirt from entering the conveyor, consisting of a flexible material sheet (1), capable of being curved (2) near the cutting blade area (3) of a cutting platform (4), containing an inclined portion (8) and another curved portion (5) near the conveyor (6).

An agricultural mounted implement for the cleaning of harvested material, which cleaning is mobile and operated on a vehicle, said implement having an implement frame, a fan, and a cleaning unit. The cleaning unit has a pick-up for picking the harvested material to be cleaned; a first air distributor base connected to the fan via an air conveying channel and has a first air passage; a conveyor unit via which the cleaned harvested material is ejected from the cleaning unit; and a drop sieve which is mounted on the implement frame so as to be congruently below the conveyor unit. During operation, the fan sucks in an air flow, guides it under the first air distributor base and blows it out through the first air passage counter to the force of gravity such that the harvested material picked by the pick-up is transported to the conveyor unit.

A fan control system for a variable pitch fan of a work vehicle includes a blade pitch module that adjust a pitch of a plurality of blades of the variable pitch fan to generate airflow in a first direction. A reversing module selectively commands a fan reversal that includes instructing the blade pitch module to temporarily adjust the pitch of the plurality of blades to generate airflow in a second direction. A first timer module, in response to the reversing module commanding the fan reversal, resets and increments a first timer and compares the first timer to a first threshold. A first reversal prevention module, in response to the first timer being less than the first threshold, prevents the reversing module from commanding a fan reversal by indicating that a first type of fan reversal is not permitted.

A clean out system of a header for an agricultural vehicle including at least one cover having a plurality of perforations and at least one actuating member connected to the at least one cover. The at least one actuating member is configured for moving the at least one cover between a first position to completely cover at least one cutout of the frame of the header for blocking the unwanted material from exiting the header, a second position to at least partially uncover the at least one cutout for permitting the unwanted material to pass through the at least one cutout, and a third position to align at least one perforation of the plurality of perforations with the at least one cutout for permitting the unwanted material to pass through the at least one cutout and the at least one perforation of the plurality of perforations.

A cleaning system of a header for an agricultural vehicle. The header includes a frame with a floor having at least one cutout therein. The cleaning system includes at least one door, an elongated member operably connected to the at least one door, and at least one actuator connected to the elongated member. The elongated member is rotatable by the at least one actuator to slide the at least one door between a first position for covering the at least one cutout and a second position for at least partially uncovering the at least one cutout and allowing an unwanted material to pass through the at least one cutout.

A clean out system of a header for an agricultural vehicle. The header includes a frame with a floor having at least one cutout for allowing an unwanted material to pass therethrough. The clean out system includes at least one door configured for pivotally connecting to the floor and selectively engaging with the at least one cutout, a latching mechanism connected to the at least one door and configured for securing the at least one door to the frame, and at least one actuating member operably connected to the at least one door and configured for selectively latching the latching mechanism and pivoting the at least one door in between an open position and a closed position.

A system and method for reversing a rotational direction of an auger of a header. The system includes a fluid line for delivering fluid to a motor that drives the auger. A directional flow control valve is connected to the fluid line and is movable between a first state in which the valve is configured to deliver the fluid to the motor in a first fluid direction to cause the motor to move the auger in a first rotational direction, and a second state in which the valve is configured to deliver the fluid to the motor in a second fluid direction that is different from the first fluid direction to cause the motor to move the auger in a second rotational direction that is opposite to the first rotational direction.

A reinforced feeder housing for an agricultural machine includes a housing body having a top surface, a bottom surface, and two opposing side surfaces each extending between the top and bottom surfaces. The housing body includes a front opening through which crop material is directed into the feeder housing from a header of the agricultural machine, and a rear opening that is substantially opposite the front opening through which crop is expelled from the feeder housing and is delivered to a threshing mechanism of the agricultural machine. Various panels of the housing body are reinforced to improve the structural integrity of the feeder housing and prevent damage to the welds in the housing body.

A forage harvester includes a shear bar and a panel that directs the crop material downstream of the shear bar. A processing component is disposed downstream of the panel. An impact sensor is coupled to the shear bar and operable to detect data related to a magnitude of a force applied to the shear bar. The panel is moveable from a first position to a second position. The first position of the panel forms a channel for directing the crop material in the direction of crop processing along a first path toward the processing component. The second position of the panel alters the channel to direct the crop material along an alternative path not including the processing component. In response to a sufficiently high impact force applied to the shear bar by debris moving with the crop material, the panel is moved from the first position to the second position.
