PURPOSE:To enhance the practical use of a farm machine in which an arm journalling a wheel is journalled to the outer surface of casing of the outer farm machine and is manually locked and unlocked, by arranging such that the arm may be simply locked and unlocked. CONSTITUTION:One end of an arm 3 journalling a wheel 7 at the middle section thereof is journalled to a predetermined position in the lower section of the casing 1 of an unhulling device, and the other end of the arm 3 is curved outward to serve as a foot pedal 4. A locking hardware 5 formed at its upper end with a hook 6 is provided to the casing 1 in the vicinity of the foot pedal 4 in order to lock and release the arm 3. Further, a lock release piece 8 made of a leaf spring for releasing the arm 3 engaged with the hook 6 is arranged below the hook 6. Further, the arm 3 is arranged such that the wheel 7 is projected downward from the lower surface of the casing when the arm 3 is engaged with the hook 6, and the arm 3 engaged with the hook 6 may be automatically released under action of the lock release piece 8 when the pedal 4 is depressed. |
