A lawnmower with a mulch plug with a plurality ramps for deflecting lawn clippings out of a cutting deck with more than one depth planes. The mulch plug is configured to attach to the lawnmower by one or more attachment points to block a collector opening of the lawnmower. The plurality of ramps comprises a first ramp and a second ramp on the lower plane of the cutting deck extending downward from the mulch plug. The second ramp is positioned further in the cutting rotation of the lawnmower on a trailing edge of the mulch plug. The secure attachment of the mulch plug with a plurality of ramps provides a more even distribution of grass clippings.

A residue vision system includes an image acquisition device configured for mounting to a harvesting machine. The image acquisition device is configured to acquire, during operation of the harvesting machine, information regarding a first pass in a field. The first pass is a harvested area of the field. During the operation, the first pass is laterally offset from a second pass in the field. An electronic control unit is in communication with the image acquisition device and with a residue distribution system. The residue distribution system is configured to be coupled to the harvesting machine to distribute residue onto the second pass and onto the first pass. The electronic control unit is configured to analyze the information acquired by the image acquisition device and to adjust a distribution of residue onto the first pass while the harvesting machine is harvesting the second pass.

A sorghum cutting header and a sorghum harvester with large feed volume and multiple reeling pans includes a reeling header, a rod crushing device, and a reciprocating cutter device. The rod crushing device is located under the reeling header. The reeling header includes reeling pans, frame rods, bearing seats, reeling pan shafts, tandem shafts, and tandem shaft bearing seats. The reeling pan shafts are installed in parallel on the frame rod through bearing seats. The adjacent reeling pan shafts are in transmission connection, and at least one reeling pan shaft is in transmission connection with the power device. An inner part of any reeling pan shaft penetrates the tandem shafts. Both ends of the tandem shafts are supported on the frame rods, and one end of the tandem shafts is fixed on the tandem shaft bearing seats. The reeling pans are mounted on any reeling pan shaft.

A device for the deaeration of a hydraulic fluid of a hydraulic system has at least one hydraulic motor arrangement and a hydraulic fluid storage which is hydraulically coupled with this hydraulic motor arrangement. A suction device for sucking out the hydraulic fluid is associated with the at least one hydraulic motor arrangement such that the suction device guides hydraulic fluid out of the hydraulic motor arrangement into the hydraulic fluid storage by means of vacuum pressure (Δp). The suction device is constructed as a jet pump and is integrated in the return line between the hydraulic motor arrangement and hydraulic fluid storage.

In one aspect, a system for monitoring crop yield for an agricultural harvester includes a material processing system configured to receive a flow of harvested materials, a first sensor configured to generate data indicative of a volume of the flow of harvested materials being directed through the material processing system, and a second sensor configured to generate data indicative of a density of the flow of harvested materials being directed through the material processing system. In addition, the system includes a computing system communicatively coupled to the first and second sensors, with the computing system being configured to determine a mass flow rate of the flow of harvested materials through the material processing system based at least in part on the data received from the first and second sensors.

A harvester monitoring system configured to determine one or more parameters associated with harvested items, the system comprising: a camera module having a field of view and configured to generate image data associated with the harvested items; a mounting bracket configured to secure the camera module to a harvester such that a conveyor of the harvester is within the field of view of the camera module; a location sub-system configured to determine and output location data representative of a geographical location of the harvester monitoring system; and a processing unit configured to receive the image data and the location data, to determine one or more parameters associated with the harvested items, and to record the one or more parameters in association with the location data on a computer readable medium.

The invention relates to a method for operating a harvesting machine for harvesting a crop in a field, at least one operating value for a working part of the harvesting machine being determined in dependence on at least one plant property of the crop. According to the invention, it is provided that the plant property is mapped in a plant growth model, the plant growth model modelling a development over time of the plant property and determining a predictive value or a predictive characteristic of the plant property for the time of the harvest.

A harvester including a mono-camera having a first field of view, where the camera outputs a first image representative of the first field of view, and where the first image is a two-dimensional representation of the first field of view. The harvester also includes a controller in operable communication with the mono-camera, where the controller establishes a second two-dimensional reference frame fixed relative to the first field of view, where the controller identifies a reference point within the first image, where the controller locates the reference point within the second two-dimensional reference frame, and where the controller calculates the location of the reference point relative to the first, three-dimensional reference frame based on the position of the reference point within the second two-dimensional reference frame.
