PROBLEM TO BE SOLVED: To directly support the load from front wheels by a main frame, and compose central differential cases of front axles of a light material. SOLUTION: A sulky type rice transplanter 10 has a right and left pair of main frames 18 arranged nearly parallel along the front and rear direction of a machine body. A front axle case 21 supporting front wheels 12 is installed in the main frames 18. When supporting the front axle case 21, if final cases 21a at right and left both end sides of the front axle case 21 are directly fixed to the right and left main frames 18, the load which the front wheels 12 accept from a road is supported by the main frames 18 through the final cases 21a, and because the load from the front wheels 12 is not directly applied to the central differential case 21b, the central differential case 21b can be made of a light aluminum alloy cast, etc.
