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.

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.

A landscaping marking system comprising a plurality of individually selectively actuated pop up visible markers mounted adjacent subterranean features of interest, wherein each marker includes pop-up visible components moveable between a popped up deployed visible position and a stored non-visible position and that may be reset to the stored non-visible position; and a controller for selectively actuating each marker.

A system includes a series of converters provided along a boundary of an agricultural cultivated area. A converter is configured to emit a second signal in response to an incoming first signal. The system also includes an autonomously driving agricultural machine including a transmitting device configured to emit the first signal in an environment of the agricultural machine, a receiving device configured to receive the second signal emitted in response to the first signal, and a processing device configured to determine a position of the agricultural machine with respect to the boundary based on the received second signal. An arrangement and/or a conversion characteristic of converters is designed differently at a first section of the boundary than at a second section of the boundary.

An agricultural implement includes a frame supporting a plurality of ground-engaging tools and a foldable marker assembly having a first marker arm coupled to the frame at a first pivot joint. The first marker arm is operable to pivot between an extended position extending laterally outward from the frame and a folded position at an acute angle relative to the frame.

A traveling assistance system for an agricultural machine includes a position detector to detect a position of an agricultural machine, a criterion creator to create a determination criterion located forward of the agricultural machine for determination about a turn of the agricultural machine, an area identifier to identify a first area and a second area, the first area being an area in which the agricultural machine travels in a predetermined circumferential direction and the working device performs work, the second area being an area which is a portion of an agricultural field, which is adjacent to the first area, and in which entry of the agricultural machine is prohibited in advance, and a setter to, in a case where the determination criterion is located in the second area, set a turning portion at a position in the first area and between the agricultural machine and the second area.

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.
