Also, since the recoil rope (50) is provided below the step-and-casing body (26), the recoil rope is provided.
Mud does not adhere to (50), so that troubles such as wear and snagging do not occur.

In the above embodiment, in the riding rice transplanter equipped with the engine (2) with the recoil device, the grip for operating the recoil is used and the seat surface (13A) of the driver's seat (13) is viewed from the side. Step below the straight line that passes
(26A) is located at a position (52A) above a straight line passing through the upper surface of
Since it is configured to be operable in the direction close to 3), when the driver starts the engine, the driver can operate the gripper (52) for recoil operation while sitting in the seat. It is easy to apply force during the lifting operation of the gripping rod (52). In addition, the driver can start the engine only by pulling-up operation in a stable manner, so that the starting operation is easy and the work efficiency is improved.

Also, the gripper (52) for recoil operation is located above the upper surface of the step, so that muddy water does not adhere to the operation tool (52) and the operation tool (52) can be operated. Sometimes hands do not slip.

[0024]

According to the present invention, the gripper for recoil operation is disposed between the rear end of the hood and the front end of the driver's seat in a side view, and the seat surface of the driver's seat is provided. And below the straight line passing through the upper surface of the step, and at the time of recoil operation, the gripping device can be pulled upward in order to approach the driver's seat. Therefore, when the driver starts the engine, the driver is seated, the upper body is bent forward, the grip for recoil operation is gripped, and the upper body is leaned forward. While raising the state, the pulling operation can be easily performed to bring the gripping tool closer to the driver's seat. Therefore, the driver can easily and reliably perform the engine start operation only by the pulling-up operation in a stable posture, and can improve the engine start operation efficiency.

Since the grip for recoil operation is located above the upper surface of the step, muddy water does not adhere to the grip and the driver's hand is required to operate the grip. The problem of slippage does not occur.
