The present invention relates to devices and methods for loading grain into a grain bag using a grain bagging apparatus that can expand and contract to accommodate different grain bag sizes. The apparatus is comprised of an expandable grain discharge tunnel. This expandable tunnel comprises a stationary section and a flanking side. The flanking side can expand in an outwardly direction away from the stationary section to increase the overall width of the grain discharge tunnel such that differently sized grain bags can be utilized with a single grain bagging apparatus. The flanking side can be slid in an inwardly direction towards the stationary section into a first position for use with smaller grain bags. In the first position, the apparatus is easier to transport or store. The grain bag can be loaded onto the grain bagging apparatus in a first position and then the expandable grain discharge tunnel can be expanded into the second position.

A crop elevator for a combine harvester includes an ascending section and a descending section and a housing enclosing the ascending section and the descending section. The elevator further comprises an elevator loop arranged inside the housing which includes a plurality of paddles for elevating a harvested crop. The elevator also includes a weighing system configured to determine a weight of harvested crop that is present on at least one of the paddles during an ascending movement of the at least one of the paddles in the ascending section. The weighing system includes a weight sensor configured to output a weight signal representative of the weight of the harvested crop. The ascending section of the elevator comprises a measurement section, wherein the weighing system is configured to retrieve the weight signal when the at least one of the paddles is in the measurement section of the elevator.

A process for weighing a harvested crop stored in a tank of a harvesting machine, a frame supporting the tank is mounted on a wheel set by a lifting device which is operable to move the frame upwardly and downwardly upon control of a hydraulic system. The process controlling the hydraulic system and includes the steps of: determining at least one height position of the frame on the displacement course; measuring a lowering pressure and a raising pressure in the hydraulic system at the position; calculating, from the measured pressures, a balancing pressure for the frame. The process is performed before unloading the stored crop in order to calculate a loaded balancing pressure and after the unloading in order to calculate an empty balancing pressure. The weight of the stored crop is calculated from a pressure variation between the loaded balancing pressure and the empty balancing pressure.

An agricultural machine includes a first threshing rotor and a second threshing rotor positioned adjacent to the first threshing rotor. Each threshing rotor is configured to rotate to process harvested crop. The agricultural machine includes first and sensors configured to measure a parameter indicative of crop load on the first threshing rotor and on the second threshing rotor, respectively. The agricultural machine includes a controller configured to change distribution of harvested crop in the agricultural machine based on a comparison between the measured parameter received from the first sensor and the measured parameter received from the second sensor.

A harvest weighing mechanism utilizes a variable speed conveyor comprised of evenly spaced solid rods such that marketable product is suspended on the rods while small foreign material falls between the rods. The product moves at the same velocity as the conveyor until discharged and directed into an impact plate attached to an impact sensor. As the product collides with the impact plate the resultant deflection of the impact plate is converted to an electronic signal which is sent to a control box which uses an algorithm to convert radial velocity to linear velocity and through laws of energy conservation determines the weight of the product required to cause the deflection measured by the impact sensor.
