摘要： To provide a working vehicle configured to be operated with easy speed shifting even when an operation lever for speed shifting is difficult to operate due to the operator's posture or other factors.
The working vehicle (1) includes an operator seat, an armrest (15) arranged on a side of the operator seat (10). The armrest (15) includes an upper surface (16a) on which an operation tool arrangement portion (19) is arranged, the operation tool arrangement portion (19) arranging an operation tool; and a side surface (16d) having a concave portion (15a). The concave portion (15a) is located on an area overlapping, in a front-to-back direction, with another area including the operation tool arrangement portion (19).

摘要： A working vehicle (1) includes: a clutch (5d) displaceable to a connected state in which power is transmitted to a drive (7), a disconnected state in which the transmission is disconnected, and a half-clutch state in which power is slidably and partly transmitted to the drive (7); a detector (53) that detects an operation position of a clutch pedal (32A) and outputs a detected value corresponding to the operation position detected; a control device (40) that brings the clutch (5d) into the half-clutch state if the detected value corresponds with a threshold, and brings the clutch (5d) into the disconnected state if the detected value is less than the threshold and into the connected state if the detected value is greater than the threshold, and vice versa; and a change unit (40A) that changes the threshold to a different value in accordance with an operation on the operation member (45).

摘要： [Problem] To provide a work vehicle that alleviates a shock that may occur during a speed change by circumventing stalling of a motor caused by a speed increase in a speed change apparatus and also circumventing over-rotation of the motor caused by a speed decrease in the speed change apparatus.
[Means for Solving the Problem] A work vehicle according to the present invention includes a rotationally driven motor; a traveling vehicle body on which the motor is mounted; a travel apparatus that is provided to the traveling vehicle body and is also driven by drive power from the motor; a work apparatus that performs work on a farm field; a speed change apparatus that changes the speed of drive power that is input from the motor and transmits the drive power; a speed change operation tool that includes a plurality of speed change stages and is also capable of speed change operation of the speed change apparatus by way of a human operation; a speed change controller that, when the number of speed change stages is changed over a plurality of stages based on human operation of the speed change operation tool, outputs to the speed change apparatus a speed change command for each predefined number of stages and is also capable of outputting the speed change command for each defined speed change interval; and an operation mechanism that enables adjustment of the speed change interval.

摘要： A work vehicle, wherein, in the first mode, the controller (H) is configured to control the travel speed of the work vehicle so as to be consistent with a travel speed to be set by the speed controller; in the second mode, the controller is configured to control the travel speed of the work vehicle so as to be lower than a travel speed to be set by the speed controller; during vehicle travel in the first mode, the controller is configured to switch the first mode to the second mode when either: the detector (43) detects that the coupling member (31) positions at the releasing position, or the detector does not detect that the coupling member positions at the coupling position; and during vehicle travel in the second mode, the controller is configured to switch the second mode to the first mode when: the detector detects that the coupling member positions at the coupling position, and the controller (H) determines that a releasing movement is performed by the speed controller (17, 44).

A working vehicle (1) includes an operator seat (10), an armrest (15) arranged on a side of the operator seat (10), and a speed shifter to change a traveling speed. The armrest (15) includes an operation lever (21) to be swung back and forth to cause the speed shifter to perform acceleration and deceleration, and an operation switch (30, 31, 32, 34, 35) to be pressed to cause the speed shifter to perform acceleration and deceleration.

摘要： A working vehicle (1) capable of easily steering a vehicle body (3) is provided. The working vehicle (1) includes the vehicle body (3) to travel, a steering handle (30) to be turned to steer the vehicle body (3), and a steering switch (153) to steer the vehicle body (3) separately from the steering handle (30). The steering switch (153) may be a switch to be operated in a pressing manner or in a sliding manner for steering the vehicle body (3). In addition, the steering switch (153) may be arranged around the steering handle (30). ( Fig. 1 )
