Claims

[Scope of utility model registration request]

In the mobile agricultural machine 1 in which the rotation of the engine 5 is transmitted to the transmission 9 via the transmission mechanism operated by the transmission operation lever 30, the transmission operation lever 30 has a large number of locking grooves provided in the lever guide plate 26'. 26 d~26
i, the transmission mechanism can be sequentially locked in a large number of shift operation positions from high speed to low speed and power cutoff positions, and the transmission mechanism can be locked in individual shift states and power cutoff positions corresponding to the shift operation positions of the shift operation lever 30. The belt-type continuously variable transmission mechanism 7 is configured to be able to change the state and position, and a push plate 33 is slidably provided in the vicinity of the locking grooves 26d to 26h corresponding to the shift operation position of the lever guide plate 26. , the lever push plate 33 is actuated by operating the disconnection lever 35 disposed on the handle portion 6, and the shift operation lever 30 in the shift operation position is pushed out from the locking grooves 26d to 26h of the lever guide plate 26 to cut off the power. A speed change operation device in a mobile agricultural machine 1 configured to return to a position.
