PROBLEM TO BE SOLVED: To provide a ridger for scallions operable with less labor and which will not give damages to crops.SOLUTION: The ridger for ridging having ridging means and a front wheel is mounted at the front of a traveling machine for farm working. In this state, the front wheel, the ridging means and driving wheels for the traveling machine are arranged from the front. Since a field is furrowed and earthed up before hardening the field with the driving wheels, the small labor for the operation is required. Furthermore, there is no risk of rolling leaves in the driving wheels. When the ridging means and the driving wheels are arranged on one straight line parallel to the forward direction, the driving wheels of the traveling machine are passed through the hard part furrowed with the ridging means. Hence, the driving force can be fully exhibited. As a result, the ridger is particularly effective for the scallions cultivated in sandy soil with the soft surface.COPYRIGHT: (C)2009,JPO&INPIT【課題】少ない労力で操作でき、かつ作物に損傷を与えることの少ない、ラッキョウの培土機を提供する。【解決手段】農作業用走行機の前方に、培土手段及び前輪を有した培土用の培土機を取り付ける。この状態で、前方から前輪、培土手段、走行機の駆動輪という配置にする。駆動輪で圃場が固められる前に培土手段によって作溝し、土寄せされるので、操作に必要な労力が少なくて済む。さらに、駆動輪が葉を巻き込むおそれがない。また、培土手段と駆動輪とを進行方向と平行の一直線上に配置すると、培土手段で作溝された固い部分を走行機の駆動輪が通るので駆動力が十分発揮できる。このため、表面の柔らかい砂地に栽培するラッキョウに特に有効である。【選択図】図1
