    摘要： Control method for a tractor (1) having a TIM control unit (7) that is designed to be electrically connected with an implement (2) and/or a with navigation system (8) through respective buses (9,10) and is designed to allow bidirectional exchange of control data; said TIM control unit (7) being designed to perform a Tractor Implement control Method for acting on electro-mechanical unities of the tractor and controlling tractor functions and steering automation based on signals provided by the implement (2) and/or navigation system (8). The method comprising the following steps: activating the TIM control and displaying (11) a specific indication (12) when the TIM technology control is active; disabling by the steering control unit (19) the steering automation when the speed the tractor (1) is zero or close to zero by opening a switch (16) supplying power to a solenoid valve (15) of an hydraulic system of the tractor (1), when steering automation is disabled the TIM automation is still active but in a limited manner; sensing the position of the switch and displaying (11) a specific indication (18) of limited steering automation once the solenoid valve is in an open position.

    摘要： For allowing automatic steering at the time of rearward traveling to be easily performed, a working vehicle (1) is provided, comprising a vehicle body (3) capable of traveling either by either manual steering with a steering wheel (30) or by automatic steering with the steering wheel (30), a reference registering unit (150) configured or programmed to register a traveling reference line (L1) based on a position of the vehicle body (3) caused to travel by the manual steering, an automatic steering control unit (200) which performs control by the automatic steering on a set scheduled traveling line (L2) based on the traveling reference line (L1), a display device (45) configured to display information about the automatic steering when forward traveling by the automatic steering is to be performed, and a notification device (95, 96) configured to issue a notification of the information about the automatic steering aside from the display device (45) when rearward traveling by the automatic steering is to be performed.

    摘要： Automatic steering control is prevented from being performed when a positioning device (30) is in the second position (X2). A working vehicle (1) includes the positioning device (30) to detect a position of a vehicle body (5) based on a signal transmitted from a positioning satellite. The positioning device (30) is supported so as to allow the positioning device to be shifted between a first position (X1) and a second position (X2) lower than the first position (X1). A mounting stay (47) is disposed below the positioning device (30) when the positioning device (30) is in the first position (X1), and, when the positioning device (30) is rotated together with the mounting stay (47) from the state in which the positioning device (30) is in the first position (X1), the positioning device (30) is moved to the second position (X2) and the mounting stay (47) is positioned above the positioning device (30) in the second position (X2) and covers over the positioning device (30) so as to restrain the automatic steering control.

    摘要： A working vehicle (1) is provided that is capable of preventing a positioning device (30) when unused from hitting an obstacle. The working vehicle (1) includes the positioning device (30) to detect a position of a vehicle body (5) based on a signal transmitted from a positioning satellite. A mounting stay (47) pivotally supported by a base stay (46) has a counter surface that opposes an upper surface of the base stay (46) when the positioning device (30) is in a first position (X1). The positioning device (30) is configured to be shifted from the first position (X1) to a second position (X2) according to rotation of the mounting stay (47) causing the counter surface to face upward. The mounting stay (47) is configured so that, when the positioning device (30) is in the second position (X2), a front portion of the mounting stay is higher than an upper end of the roof (16) and a rear portion of the mounting stay is lower than the upper end of the roof (16).
