<p>PROBLEM TO BE SOLVED: To provide a riding type transplanter that prevents a full bump of a suspension spring while keeping a small size of a front axle case.SOLUTION: A damper 50that attenuates at least a rising direction movement of a king pin shaft 37 is disposed above a front axle case 29. For example, the damper 50includes a damper case 51 with oil encapsulated therein, and a piston 52 to be integrally moved with the king pin shaft 37. Upon rising or falling of the king pin shaft 37, the oil is moved through a throttle oil channel 57 disposed in the piston 52, thereby obtaining an attenuation force.</p> |
