PROBLEM TO BE SOLVED: To solve the problems in which: in a tiller (for example, small cultivator), soil surface tilled by a tilling tine rotor is ridged and nursed by a wing hiller (ridger) if a special wing hiller is attached, the tiller is increased in size and weight, and output house power is further required so that workability and operability are likely to be deteriorated and mounting operation of the wing hiller becomes complex to take trouble.SOLUTION: In a tiller, a substantially square-shaped rear cover 6 is installed vertically rotatably at a rear lower end edge part of a rotor cover 2 covering an upper peripheral part of a tilling tine rotor 1. The rear cover 6 comprises: a grooving nursery soil plate 3 which is a reverse trapezoidal shape in a front view and which is located at a substantially central part of the rotor cover 2 in a width direction and a slope pressing plate 5 which can rotate backward with respect to right and left nursery lateral plate edges 4 of the grooving nursery soil plate 3. A scraping and leveling plate 7 is installed at a rear end edge of the rear cover 6.COPYRIGHT: (C)2015,JPO&INPIT【課題】 耕耘機(例えば、ハンドカルチベータ等)にあっては、この耕耘爪ロータによって耕耘される土壌面を培土器(畝立器)によって畝立培土するために、特別の培土器を装着すると、構成が大形化、重量化されることになり、出力馬力を大きくすることとなって、作業性、操作性も低下し易くなる。又、培土器の着替え操作も煩雑化して、手数を要する。【解決手段】 耕耘爪ロータ1上周部を覆うロータカバー2の後下端縁部に、このロータカバー2の横幅方向の略中央部に位置させる正面視逆台形状の溝切培土板3と、この溝切培土板3の左右培土側板縁4に対して後側へ回動可能の法面押圧板5とからなる略方形状のリヤカバー6を、上下回動可能に設け、前記リヤカバー6の後端縁に掻き均板7を設ける。【選択図】 図3
