摘要： PROBLEM TO BE SOLVED: To provide a seal part for preventing leakage of a lubricating oil easily by providing a pair of right and left vertical shaft transmission parts for axially supporting the front wheels at the lower end, elongating downward from lateral shaft transmission parts of a transmission case, and providing a lubricating oil reservoir comprising a main body part and the lateral shaft transmission parts. SOLUTION: Vertical shaft transmission parts 70 elongating downward, are provided on the ends of lateral transmission shafts 61 elongating in lateral shaft transmission parts 60 elongating on the right and left sides of a transmission case such that the rotation of each of the lateral transmission shafts 61 is transmitted to a vertical transmission shaft 74 via bevel gears 71a, 71b. The rotation of the vertical transmission shaft 74 is transmitted to a front axle 73 so as to rotate driving front wheels 1. The vertical shaft transmission part 70 comprises upper case parts 70A formed integrally with the lateral shaft transmission part 60 and rotatable lower case part 70B. The connecting part for the case parts 70A, 70B is provided at a rotatable part 70C for steering. A part of a transmission case main body above the rotatable part 70C, and the lateral shaft transmission parts 60 provide a lubricating oil reservoir.

摘要： PROBLEM TO BE SOLVED: To provide a steering operating device for a working machine in a paddy field which is even a mobile apparatus equipped with a side clutch brake and scarcely damaging a field while performing a turn as small as possible. SOLUTION: This steering operating device is obtained by installing a release member for acting on a side clutch brake for left and right rear wheels and performing changeover from a state of the disengaged clutch to a brake state, providing uneven cam faces 50A and 51A on the opposite lateral faces to a clutch member 51 arranged oppositely to the release member, making the clutch member 51 approach the release member with a steering pedal, engaging the cam faces 50A with 51A, normally or reversibly moving the release member in the shaft center direction and alternately carrying out the changeover from the state of the disengaged clutch to the state of the engaged clutch so as to produce a semitransmitting state for intermittently rotating the rear wheel on the inside of the turning to an extent not to drag the rear wheel.

摘要： PROBLEM TO BE SOLVED: To cope with an automatic clutch operation specification and a manual clutch operation specification with a single transmission case by allowing a shift control valve to set the automatic clutch operation specification. SOLUTION: A main clutch 53 is engaged only when a rocking arm 64 is located at a forward position F and a reverse position R, and the main clutch 53 is kept disengaged when the rocking arm 64 is located at other positions. The main clutch 53 is engaged after the synchronous action of gear engagement by a forward/reverse switching action is completed. If a clutch pedal 19 is depressed when an oil path 74 is opened in the forward state or the reverse state, the main clutch 53 can be forcefully disengaged. This structure is an automatic operation specification constituted of the end section of a shift shaft 62 and a transmission case 10 of the portion shiftably surrounding it, and a forward/reverse switching action can be taken merely by a single action for moving a shuttle bar 17.
