A mowing device for mowing material between rows of planted crops in an agricultural field, comprising a series of mower assemblies attached to a tractor and spaced from each other so that each mower assembly is located between an adjacent pair of rose of a printed crop. Multiple blades are mounted for rotation on each mower assembly for cutting material growing in the space between adjacent pairs of rows of a planted crop. A first deflector in front of each mower assembly moves planted crops around the outside of the mower assemblies so as not to be cut by the mower assemblies. A second deflector may be provided within each mower assembly and located rearwardly of the blades to push mowed material laterally toward the adjacent rows of a planted crop.

Implementations are described herein for analyzing vision data depicting undesirable plants such as weeds to detect various attribute(s). The detected attribute(s) of a particular undesirable plant may then be used to select, from a plurality of available candidate remediation techniques, the most suitable remediation technique to eradicate or otherwise eliminate the undesirable plants.

One variation of a method for executing agricultural actions on an agricultural field includes: based a type of a crop planted on the agricultural field and a maturity of the crop, setting a nominal blade gap width of a weeding module installed in an autonomous agricultural vehicle; and, at the autonomous agricultural vehicle, while autonomously traversing the agricultural field, detecting a first target plant passing under the autonomous agricultural vehicle and aligned with the weeding module, triggering the weeding module to open a set of weeding blades to the nominal blade gap width at a nominal blade speed in response to the first target plant approaching the weeding module, and triggering the weeding module to close the set of weeding blades in response to the first target plant passing the weeding module.

The invention relates to an adjustable hoeing device (10) for removing weeds situated on a ground surface, the hoeing device (10) having a supporting frame (50), on which there is arranged at least one hoeing unit (100), which hoeing unit comprises the following:at least one main bar (200) and at least two transverse bars (250) arranged parallel to one another, which transverse bars (250) are each mounted rotatably on the at least one main bar (200);at least two connection bars (300), which run parallel to the at least one main bar (200) and which mechanically connect the at least two transverse bars (250) to one another;at least two blades (500), wherein the blades (500) are arranged on the at least two transverse bars (250) at a normal distance from the main bar (200); andat least one actuation device (400), which acts on at least two transverse bars (250) or a transverse bar (250) and the main bar (200) in order to rotate same by means of a linearly displaceable actuation arm.

Herein provided is an autonomous unmanned ground vehicle (AUGV) and handheld device for pest control. The AUGV comprises a chassis with a drive mechanism to displace the AUGV among a plurality of plants comprising at least one weed; an image-capture device to obtain images of the plurality of plants; a motorized arm with a free end displaceable with respect to the chassis; a microwave emitter mounted to the free end, displaceable therewith, and operable to emit microwaves; and a control system to operate at AUGV. The control system comprises a processing unit; and a memory having stored thereon instructions to cause the AUGV to perform: independently navigating the chassis among the plurality of plants; identifying the at least one weed in the images; displacing the motorized arm to position the free end in proximity to the at least one weed; and emitting microwaves toward the at least one weed.
