The cutter implement may include a housing, a cutter, and a curtain. The housing has a forward end for engaging the crop material when moving in a direction of operation. The housing at least partially defines a cutting region disposed at the forward end. The cutter is coupled to the housing and can cut the crop material in the cutting region. The curtain is coupled to the forward end of the housing and is positioned forward of the cutter relative to the direction of operation for engaging and leaning the crop material upstream of the cutter. The curtain includes a stiffness control feature operable to control a vertical stiffness of the curtain to provide a variable vertical stiffness that increases with an increase in a bend angle of the curtain rearward relative to the direction of operation.

A harvester (1), comprising a harvester aggregate (2) for felling, trimming and preparing tree trunks, a first measuring device (I) provided in connection with the harvester aggregate (2) for measuring of at least one dimension of a tree trunk. The harvester comprises a second measuring device (II) for measuring a feature of the first measuring device, whereby said feature is an attribute reflecting the capability of the first measuring device to measure said dimension correctly, and a control unit (11) configured to make a comparison between an actual value (a) of the measured feature and a target value (β) of said feature, whereby the target value is indicative of a state of the first measuring device, where its measurement of said dimension is considered to be correct.

A plant harvesting system for use with a vertical hydroponic tower, the hydroponic tower containing a plurality of vertically aligned plants. The harvesting system includes a payload transport system and a harvester. The payload transport system, which is configured to be positioned at a location adjacent to the hydroponic tower, includes a base and a lift tower, the lift tower including a motorized lift system configured to move the harvester upward and downward. In addition to cutting plant stalks while moving upwards along the face of the hydroponic tower, the harvester also groups and collects the plant leafs.

A harvesting header is disclosed that comprises a support frame and a crop moving apparatus supported on the support frame and operable for moving cut crop material to a transfer region. The header also has a cavity located proximate and lower than an output end of the crop moving apparatus. The header has a crop flow assistance device having a plurality of transversely spaced elements that extend generally longitudinally at least partially above the cavity, and which are operable to assist cut crop material in being transferred from the output end of the moving apparatus to flow over the cavity. The cavity may be operable to receive rocks and/or debris carried by the conveyor to the transfer region. The header may include a rock trap located in the transfer region the cavity being part of the rock trap and may be operable to receive rocks and/or debris carried by the conveyor to the transfer region.

An agricultural vehicle including a chassis and a header connected to the chassis. The header includes a frame, at least one crop divider connected to the frame and having a crop divider body with at least one opening therein, and at least one down crop gatherer rotatably mounted to the at least one crop divider and at least partially extending through the at least one opening of the crop divider body. The at least one down crop gatherer has a first rotational direction. The header also includes a drive unit rotatably mounted to the at least one crop divider and contacting the at least one down crop gatherer. The drive unit has a second rotational direction and is configured for contacting the field and driving the at least one down crop gatherer in its first rotational direction.
