A working vehicle includes a radiator that cools cooling water of an engine and a plurality of first cooling devices disposed on a front side of the radiator and slidably provided with respect to a vehicle body, in which the first cooling devices include an oil cooler that cools oil and a condenser that cools a refrigerant of an air-conditioning unit.

A working machine (1) includes a machine body, an operator's seat provided on the machine body, an operator's seat protector to protect the operator's seat, a support body (41) to support the operator's seat protector, the support body (41) including a placement portion (42) for placement of the operator's seat protector thereon and a front leg portion (43L,43R) extending diagonally forward and downward from the placement portion (42) and attached to the machine body), a weight (46) provided at a rear portion of the machine body (2), and a connector member (47) to connect an upper portion of the weight (46) and the support body (41). The weight (46) is configured to support a portion of the support body (41).

A swinging body pivot mechanism (P) includes a pivot shaft (2), a first member (31) and a second member (32) coupled to each other via the pivot shaft (2) swingably relative to each other and a rotation stopper (3) attached to the pivot shaft (2). The rotation stopper (3) includes an insertion portion (3e) into which a rotation stopper pin portion (31b) of the first member (31) is inserted. The insertion portion (3e) includes a first width (Wr) in a direction along a first straight line (Dr) that is an imaginary line which extends in a direction matching a radial direction of the pivot shaft (2) and a second width (Wt) in a direction along a second straight line (Dt) that is an imaginary line which is perpendicular to an axis (2a) of the pivot shaft (2) and the first straight line (Dr). The first width (Wr) is defined such as to allow the rotation stopper pin portion (3 1b) inserted in the insertion portion (3e) to change a position thereof in the direction along the first straight line (Dr). The second width (Wt) is defined such that the rotation stopper (3) and the rotation stopper pin portion (31b) are restricted from moving relative to each other in the direction along the second straight line (Dt), the rotation stopper pin portion (31b) being inserted in the insertion portion (3e) and abutting the rotation stopper (3) at at least one of the opposite ends (3e1, 3e2) of the insertion portion (3e) in the direction along the second straight line (Dt).

A rotational structure (40) includes a base (29), a detected body (49) fixed to the base (29), a pivot (41) supported on the base (29) such that the pivot (41) is rotatable about an axis (Y), a swing bracket (42) attached to the base (29) via the pivot (41) and configured to rotate relative to the base (29) by rotating together with the pivot (41), a sensor (47) to detect the detected body (49), and a sensor bracket (44) fastened to the swing bracket (42) to support the sensor (47).

A working machine (1) includes a machine body (2), a traveling device (3) to support the machine body (2) such that the machine body (2) is allowed to travel, an operator's seat (4), a protector (8) provided on the machine body (2) to protect the operator's seat (4), and a position detector (40) to acquire position information from one or more positioning satellites. The protector (8) includes a roof (17) provided above the operator's seat (4). The position detector (40) is housed in the roof (17). (Fig. 2)

A method and a system for training an artificial intelligence (AI) model for agricultural pruning includes generating a training group (S26-1) that corresponds to a portion of a fruit tree, generating a training data point based on the training group (S26-3), and training the AI model using the training data point (S26-4). The training data point includes a pruning decision for each of one or more canes included in the training group, and a measurement value concerning one or more attributes for each of the one or more canes included in the training group.

An agricultural pruning system includes a storage to store a plurality of trained artificial intelligence (AI) models, and a processor configured or programmed to select a trained AI model from among the plurality of trained AI models. Each of the plurality of trained AI models determines whether to remove or retain each of one or more canes of a fruit tree (200).

A cut-point generation method for agricultural pruning includes using a trained artificial intelligence (AI) model (25-1) to determine whether to remove or retain (25-4) each of one or more canes of a fruit tree (200), determining whether or not each of the one or more canes of the fruit tree includes a cut-point, and determining a cut-point location for each of the one or more canes of the fruit tree that is determined to include the cut-point.

A remote device (30) includes a remote manipulator (35) to remotely manipulate a remote working machine (1), and a display (34) to display a captured image of an area in a direction of travel of the remote working machine (1) and a path object (90) indicating an expected travel path of the remote working machine (1) such that the path object (90) is superimposed on the captured image. The display (34) is configured to display the path object (90) in a manner that corresponds to a manner in which a ground surface slopes.

A remote device (30) includes a remote manipulator (35) to remotely manipulate a remote working machine (1) configured to attach a working device (2) thereto, and a display (34) to display a captured image of an area in a direction of travel of the remote working machine (1) and a path object (90) indicating an expected travel path of the remote working machine (1) such that the path object (90) is superimposed on the captured image. The display (34) is configured to display the path object (90) in a manner that corresponds to a state of the working device (2).
