A moving robot has a body and at least one wheel for moving the main body. The moving robot has a transceiver to communicate with a plurality of location information transmitters located within an area. The moving robot also has a memory storing coordinate information regarding positions of the location information transmitters. Further, the moving robot has a controller that sets a virtual boundary based on location information determined using signals transmitted by the location information transmitters. The controller controls the wheel so that the main body is prevented from traveling outside the virtual boundary. The controller sets a reference location information transmitter and corrects the stored coordinate information by correcting height errors based on height differences between the reference location information transmitter and the other location information transmitters. The controller also corrects a current position of the main body based on the corrected stored coordinate information.

An implement for an agricultural vehicle including a toolbar and a pair of marking devices pivotally connected to the toolbar. Each marking device includes a first arm, a second arm, and a first attachment bracket pivotally connecting the first arm to the distal end of the second arm. The first and second arms are configured for pivoting between a stored position in which the first and second arms are folded relative to one another and an operational position in which the first and second arms are unfolded relative to one another. Each marking device further includes a second attachment bracket, a kick out link, and a biasing member connected to the kick out link and configured for providing a biasing force acting on the kick out link to retain the first arm relative to the second arm in the stored position.

An agricultural row unit adapted to be moved over soil by an agricultural planter to clear crop residue includes a residue clearing disk or brush. The row unit may include a motor to drive rotation of a crop residue disk or brush. The agriculture row unit may also include a controller configured to adjust the operating speed of the motor in response to factors internal and/or external to the agricultural row unit. The factors may include at least one of a speed of the agricultural planter along the row, a height of crop residue disk or brush the relative to a surface of the soil, a height of the crop residue disk or brush relative to a surface of the soil, amount of crop residue in the row, and a downforce pressure on the row unit.

One embodiment is a work machine including a frame extending along a length, a width and a height. Front and rear ground contacting wheels are rotatably coupled with the frame. A linkage is coupled with the frame and a tool mount coupled with the linkage. A suspension element accommodates movement of the tool mount in response to external force. An actuator system is structured to move the tool mount through translation and/or rotation. An edging tool assembly is coupled with the tool mount and includes a ground working implement.

A first machine of a tree planting system includes: a cultivator cultivating soil where a plant for tree planting is to be planted; a first traveling device traveling with the cultivator; and a cultivated position detector obtaining and outputting actual cultivated positions corresponding to positions of the cultivator while the cultivator travels with the first traveling device and cultivates the soil. A management device of the tree planting system stores actual cultivated positions. A second machine of the tree planting system includes: a planting device planting a plant in the soil; a second traveling device traveling with the planting device; a planting device position detector obtaining a position of the planting device; and a controller controlling a position of the planting device based on: actual cultivated positions acquired from the management device; and the position of the planting device at the timing when a plant is planted.

An agricultural implement includes the use of one or more electromechanical hydraulic cylinder assembly in place of hydraulic cylinders. The assemblies may take various forms for actuation, and can convert an electric power source to hydraulic power for use on or with the implement. A control system is also provided for connecting to a tractor to provide control information to the assemblies or to a central hydraulic supply via a ISOBUS that rebroadcasts input controls from a source, such as a tractor used in conjunction with the agricultural implement.

A hood of a tractor including a front grill, a light unit, and an upper cover is provided with a center pillar. The front grill is attached to the center pillar, the light unit is attached to the front grill, and the upper cover is supported by the center pillar. The hood is further provided with a side frame and a lower cover, where the side frame is attached to the center pillar, and the lower cover is attached to at least the upper cover and the side frame.
