14 201130407 The variable catching lever 70 is operated to the neutral detecting device 73 to detect the 彳-u region T, and the take-off stop state is taken out at the traveling speed to the center of the motor 83, by the slave control device. The output rotation of 21 stops. The hydrostatic type stepless speed change device is further configured to output the static oil pressure type by the operation of the stepless speed change unit 21 by the main key from the control unit 74 to the motor 83n on the engine start side. The second/sleeve 80 automatically rotates to the deceleration side and returns to neutral: by this means, even if the engine 22 is abnormally stopped in the state of the harvesting and transporting, the re-starting time is increased. . The large quilt is driven by high speed, which makes it safe: in the case of going from the wow to the farmland, when going downhill, it may be ^ » the weight of the harvester and the body naturally goes down ^ ss B , 乂 进 逮 逮 逮Fast, so... Foresee this point and operate the shift lever 70 down to the neutral zone on the downhill. If the missing lever I is operated in the state where the shift lever 70 is operated to the neutral zone τ, the rear-loading device is in a stopped state, so that the mast may be pushed down. In addition, 'the speed of the forward speed is exceeded before the body, and the operator may perceive the necessity of decelerating the traveling speed to operate the shift lever 70 to a position higher than the center position of the neutral zone toward the highest speed operation position of the retreating side. Here, with the above configuration, when the shift lever 70 is operated to a position Τ' which is closer to the highest speed operation position on the retreating side than the center position of the neutral zone, the speed pulse is continuously detected by the traveling speed detecting means 73. Above time, the output of the static oil-independent stepless speed change device η is automatically started, and the harvesting device 4 is driven to prevent the stem from being pushed down. Further, when the body is retracted, the shift lever 7 is moved beyond the position and moved to the position on the retreating side. However, in this state, the control device 74 is not outputted to the motor 83, and the static oil type for the harvesting and transporting is performed. The stepless speed change device η is maintained in a stopped state, and the harvesting device 4 is not driven. Thereby, the inadvertent driving of the harvesting device 4 at the time of the agricultural (four) entry can be prevented, and the operability can be improved. Further, the neutral zone T may be sighed in the shift control φ$ Ρ η π _ of the static oil-covered stepless transmission 20 for traveling, and the static oil-pressure type stepless shifting device 2 for harvesting and transporting The 1st batch is also a gentleman. The setting of the neutral zone in the wide π 1 control system is not required, so the control can be simplified. Further, when the dialing pedal is stepped on, the stepping position is detected by the position sensor Η) 3, and is output from the control unit 74 to the motor 83, and the harvesting and conveying static oil type I stepless transmission unit 21 starts outputting. That is, after harvesting the farmland and reaching the saliva, the shifting device 7 is operated to the state where the lamp is turned on, and the harvesting device 4 is in the state of the pulling device 1 〇Α _ ^ person mast Stop below. In this state, the harvesting device 4 is driven by the pedaling operation to drive the harvesting device 4, and the mast is pulled up while the mast is pulled up and dialed in, so that the wrow is on the side of the wand. In addition, this type of static oil for harvesting and transporting is not limited to one type, and the speed of rotation of the set (the rotation speed of the harvesting vehicle by %) is shifted in accordance with the stepping position of the dialing pedal, so that the harvesting can be performed. The driving speed of the device 4 is adjusted to the speed desired by the operator, and the harvesting operation of the mast of the saliva can be facilitated. In addition, it can also replace the above position sensing with the history of 0N/0FF.

16 201130407 The switch 103 is configured to output a predetermined time from the control unit 74 to the motor 83 when the pedal is depressed. As a result, by stepping on the dialing pedal, the static oil-pressure type stepless speed change device 21 for harvesting and conveying is gradually increased, and the mast of the side can be harvested.
