  • Patent number: 11516963
    Abstract: A work vehicle includes a first detection unit that detects an optical beam emitted from a beam projector disposed at one end of a reference travel path, a first position deviation calculation section that calculates position deviation by a vehicle body from the reference travel path based on a detection signal from the first detection unit, a second detection unit that detects a work boundary line that occurs due to work travel, a second position deviation calculation section that calculates position deviation of the vehicle body traveling along successive travel paths from the work boundary line based on a detection signal from the second detection unit, and a steering information generation section that, based on the position deviation calculated by the first position deviation calculation section and the second position deviation calculation section, generates steering information for correcting the position deviation.

  • Publication number: 20200178461
    Abstract: A work unit to be attached to a lower side of a work vehicle that includes a wheel includes a work portion, a housing that covers the work portion, a bridge portion that is provided above the housing, auxiliary plates that change their positions between a state of being housed in the bridge portion and a state of protruding from the bridge portion, a linkage mechanism that is provided in the bridge portion and is connected to the auxiliary plates, and an operation tool for operating the linkage mechanism. As a result of operating the operation tool, the linkage mechanism is folded or unfolded, and positions of the auxiliary plates are changed between the state of being housed in the bridge portion and the state of protruding from the bridge portion.

  • Patent number: 10377219
    Abstract: A tractor includes an engine that is mounted on a vehicle body frame, a hood that houses the engine and is configured to pivot about a front pivot in a top-bottom direction between a closed position at which the hood covers the engine, and an open position at which the hood exposes the engine, a mounting rubber that is provided between the engine and the vehicle body frame to support the engine in an anti-vibration manner, and a hood stay that supports the hood such that the hood is pivotable up/down about the front pivot. The hood stay includes an abutting-target portion against which the engine can abut from a rear side, to prevent the engine from swinging forward in a front-rear direction of the vehicle body.
