Description

Description: BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a raccoon transplanter in which seeds of raccoon are sequentially planted on a soil surface after tilling by a tilling rotary. 2. Description of the Related Art In a raccoon transplanter equipped with a seed cultivating rotary and a raccoon planting device at the rear of a traveling vehicle body, an operator's seat is provided at the rearmost portion and a plantation is provided in front of the operator. Work is performed in which the attachment device is deployed and the working posture of the worker is directed forward. [0003] However, in the case of such a means, the working seat is overhanged greatly behind the planting device, so that it is not possible to smoothly move up and down with a small and medium-sized traveling body. There are drawbacks such as difficulty in lifting and lowering. SUMMARY OF THE INVENTION Accordingly, the present invention provides a tilling rotary and a raccoon planting device which can be lifted and lowered at the rear of a traveling vehicle body, and an operator is provided substantially above a claw shaft of the rotary. In the raccoon transplanter, which has a work seat for sitting and a step between the rear of the rotary and the raccoon planting device, the front and rear supply cups and one lower receiving cup are provided.
