A combine that can accurately measure the weight of grain retained in a grain tank is provided. When a weight measurement signal is output from a measurement switch 66, a weight measurement decision unit 75 instructs a working state determination unit 71 to perform working state determination. If it is determined that the combine is in the working state, the weight measurement decision unit 75 does not instruct a load cell 39 to perform weight measurement.

A bubble up auger includes a tubular housing, a screw auger and a baffle. The tubular housing includes an inlet opening having a first width end adjacent a first end of the tubular housing and a second width end opposite the first width end. The baffle extends from the inlet opening, outwardly from the central longitudinal axis of the tubular housing and towards the first end of the tubular housing.

An antenna mounting apparatus for a combine harvester where the apparatus includes a first grain tank extension panel mounted to a frame so as to be moveable between an open, extended, position and a closed, retracted, position. An antenna-supporting bracket is pivotally mounted to the grain tank extension panel around a first pivot axis. Actuation means are provided to pivot the antenna-supporting bracket with respect to the grain tank extension member when the grain tank extension panel moves between the open position and closed position.

An automated system for moving a crop harvester relative to an obstacle in a crop field. The system includes a sensor that is configured to sense a presence of the obstacle in the crop field, and transmit a signal corresponding to the presence of the obstacle. A motor is configured to move the crop harvester relative to the agricultural vehicle. A controller is configured to activate the motor based upon the signal received from the sensor and thereby move the crop harvester relative to the agricultural vehicle to prevent physical contact between crop harvester and the obstacle.

A harvester movable along a support surface. The harvester includes an inlet configured to receive crop, a blade configured to cut the crop into billet and extraneous plant matter, and a cleaning system configured to distinguish between billet and extraneous plant matter. Billet is directed toward a conveyor configured for discharging billet to a vehicle and extraneous plant matter is directed toward a hood. The hood includes a debris director defining an outlet configured to eject extraneous plant matter as residue onto the support surface. The outlet is disposed at an angle of residue ejection with respect to the support surface. The debris director is configured to adjust the angle of residue ejection with respect to the support surface.

An elevator assembly for a harvester may include an elevator extending within between proximal and distal ends. The elevator may be configured to carry harvested crops between its proximal and distal ends. The elevator assembly may also include a storage hopper at a location adjacent to the distal end of the elevator. The storage hopper may include a rear deflector and a hopper gate. The hopper gate may be movable between a discharge position, at which the hopper gate exposes a discharge opening of the storage hopper, and a storage position, at which the hopper gate covers the discharge opening to prevent harvested crops from being discharged from the elevator assembly. Additionally, when the hopper gate is moved to the storage position, the hopper gate and the rear deflector may at least partially define a storage volume adjacent to the distal end of the elevator for storing the harvested crop.

A combine harvester includes a threshing device 4 configured to perform a threshing process of threshing reaped grain culm in a threshing chamber 23, in which the threshing chamber 23 includes a threshing cylinder 31 configured to rotate around a front-rear axis X, and an arc-shaped receiving net 32 provided extending along an outer circumferential portion of the threshing cylinder 31, and a top plate 30 covering an upper portion of the threshing chamber 23 is supported detachably along the rotation axis direction of the threshing cylinder 31.

One or more information maps are obtained by an agricultural system. The one or more information maps map one or more characteristic values at different geographic locations in a worksite. An in-situ sensor detects a material dynamics characteristic value as a mobile machine operates at the worksite. A predictive map generator generates a predictive map that predicts a predictive material dynamics characteristic value at different geographic locations in the worksite based on a relationship between the values in the one or more information maps and the material dynamics characteristic value detected by the in-situ sensor. The predictive map can be output and used in automated machine control.

A harvesting machine includes a chassis, a ground-engaging mechanism for supporting the chassis, and a tank assembly mounted to the chassis for storing a crop material. The tank assembly includes a retractable door for at least partially covering an opening formed in a top of the tank assembly. A mobile sensor assembly includes a rod and a sensor for detecting a weather condition, such that the rod includes a first end coupled to the retractable door and a second end to which the sensor is coupled. The retractable door is operably moved between an open position and a closed position, and the mobile sensor assembly is rotatably moved between a deployed position and a stowed position as the door is moved between the open and closed positions, respectively.

A harvesting machine has a crop tank and a conveyor screw inside the tank which extends from a material inlet opening on a wall of the crop tank into the interior of the crop tank. The conveyor screw comprises at least one proximal portion adjacent to the material inlet opening and one distal portion spaced apart from the material inlet opening at least by the proximal portion. The proximal portion and distal portion are rotatable around conveying axes running in different directions. The conveyor screw can be operated in a work position in which the conveying axis of the distal portion is oriented to be steeper than the conveying axis of the proximal portion.
