A drawn agricultural implement includes a main frame and a plurality of ground engaging units supporting the main frame from a ground surface. A working unit is supported from the main frame and configured to engage crops as the implement moves in a forward direction across the ground surface. A draft tongue extends from the main frame for attachment to a tractor. A camera having a field of view is mounted on at least one of the draft tongue, the main frame and the working unit. The camera is movable relative to the at least one of the draft tongue, the main frame and the working unit to reposition the field of view.

A lawnmower, and in particular a robotic lawnmower, can include a passive cleaning assembly for removing detritus from the lawnmower housing. The passive cleaning assembly can be moveably mounted on the housing. Movement of the lawnmower with respect to the ground can cause a cleaning portion of the passive cleaning assembly to move with respect to the housing, and thereby remove detritus from the housing.

An autonomous ground treatment appliance, in particular a robotic lawnmower, includes a housing, a running gear, a control unit, at least one wheel unit, and a sensor unit. The control unit is configured to control the autonomous ground treatment appliance. The at least one wheel unit is mounted on the housing so as to be at least partially movable relative to the housing. The sensor unit is configured to ascertain a position of the wheel unit relative to the housing.

An agricultural device associated with reduced tillage techniques in a field includes a frame and at least one mower module supported by the frame, the at least one mower module positionable to cut plant matter between adjacent crop rows in the field. The plant matter has penetrated a previously formed mat of at least partially crushed residual plant matter.

A method of inspecting plants for contamination includes generating a first series of images of a plant using a camera mounted to a frame being moved along a planting bed by a harvester, identifying a region of interest displayed in the first series of images as a region of contamination on the plant based on a color criterion and a morphological criterion applied to the region of interest, and transmitting data including an instruction to increase a vertical distance between the plant and a cutter of the harvester to avoid harvesting the plant in response to identifying the region of interest as the region of contamination. The method further includes generating a second series of images of an additional plant as the frame continues to be moved along the planting bed by the harvester while the vertical distance between the plant and the cutter is being increased.

According to one embodiment, provided is a method for controlling a system comprising a lawn mower robot, the method comprising: a boundary setting driving step wherein the lawn mower robot drives in order to set a boundary of a target work area in which at least three anchors are installed on the boundary thereof; a shadow area determination step wherein, in the boundary setting driving step, the lawn mower robot receives a signal from the anchors and sets, as a shadow area, an area where the signal cuts off; a driving ending step wherein when the lawn mower robot returns to an initial position, the boundary setting driving step is ended, and driving information received from the anchors is stored; an information transmission step for transmitting, to a simulator, the driving information and information on the shadow area and the target work area; an obstacle map generation step for generating, by the simulator, an obstacle map on the basis of the shadow area of each anchor; a screen output step wherein the simulator overlaps an externally provided map and the obstacle map, and outputs same on a screen; and an anchor recommending step for recommending, to a user, positions at which the size of the shadow areas identified within the target work area can be minimized. According to the present embodiment, a user can easily check whether the anchor installation positions are desirable.

A mower includes a mowing system for cutting grass, a housing, and a traveling assembly including walking wheels. The mowing system includes a cutting assembly, a driving mechanism, and a height adjustment mechanism. The cutting assembly includes a mowing element for cutting the grass. The height adjustment mechanism is used for adjusting a movement of the cutting assembly to have different cutting heights, where the height adjustment mechanism includes an adjustment motor for generating an adjustment force for adjusting the mowing element to the different cutting heights. The mower further includes a parameter detection unit and a control unit, where the parameter detection unit is configured to detect a working parameter of the adjustment motor in a working process, and the control unit is configured to identify a cutting height of the mowing element according to the acquired working parameter.
