A spectrometric measuring head for forestry, agricultural and food industry applications comprises a housing having a window and a spectrometer that is arranged inside the housing and comprises a dispersive element and a sensor, a first light source for exposing a sample to light, which reaches the spectrometer through the window after having been transmitted and/or reflected by the sample, and a standard that can be exposed to light to provide a reference for the spectrometer, which standard can be exposed to light by a light source arranged in the housing.

A conditioning roller assembly includes two conditioning rollers which are rotatably mounted on associated bearing arrangements, and a holder which includes a first holder component and a second holder component that are connected together by a hinge and a spring arrangement for providing a pre-tensioning of the conditioning rollers. The first holder component is releasably connected to the first bearing arrangement, the second holder component is releasably connected to the second bearing arrangement, and the conditioning rollers, with the bearing arrangements, are detachable in each case from the components without the holder being disassembled.

A separator for a crop harvester configured to harvest sugarcane. The separator includes a frame having: i) an inlet configured to receive cut sugarcane, wherein the cut sugarcane includes cut stalk and crop residue, ii) a cut stalk outlet configured to discharge the cut stalk from the frame; and iii) a crop residue outlet. An extractor is operatively connected to the crop residue outlet. The extractor includes a tapered nozzle disposed adjacently to the crop residue outlet and a fan disposed adjacently to the tapered nozzle, wherein the tapered nozzle is configured to provide a pressure differential between the crop residue outlet and the fan in response to air flow provide by the fan. The tapered nozzle, in one embodiment, is a truncated cone having a smaller end disposed adjacently to a flow of cut crop, wherein the fan draws air through the truncated cone to separate the crop residue from the cut stalk.

A system and method according to one embodiment are provided in a vehicle to perform a two-stage cut of grass or other vegetation in a field or lawn. The first stage may be a coarse cut stage, and the second stage may be a finish cut stage. The first and second stages may be conducted by separate cutting configurations. For instance, the first cutting configuration or coarse cutting configuration may be a flail mower configuration, and the second cutting configuration or finish cutting configuration may be a rotary cutting configuration.

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.

An unloading apparatus is arranged to direct material to a container. A controller determines a build-up speed of the material in the container; in accordance with the determined build-up speed, determine a rate of change to be applied when setting an attribute of at least one of the unloading apparatus and container; and set an attribute of at least one of the unloading apparatus and container in accordance with the determined rate of change in order to direct the material from the unloading apparatus to the container.

A method for sharpening cutting knives carried by a cutter drum in a housing of an agricultural vehicle includes: rotating the cutter drum while keeping a sharpening door closed so an overpressure is created inside the housing, the sharpening door shielding a sharpening stone from the cutting knives while creating the overpressure; opening a transition door of the housing below the cutter drum to eject crop material through the open transition door; opening the sharpening door to expose the cutting knives to the sharpening stone and closing the transition door; grinding one or more of the cutting knives with the exposed sharpening stone; and closing the sharpening door to shield the sharpening stone from the cutting knives after grinding.
