反時計回りに回せば、前述とは逆に、延長板Ｉは代掻整
地板３の方に摺動し、有効代掻幅は縮少される。In the past, when reducing the effective purging width, by turning the handle 29 counterclockwise, the extension plate I would slide toward the purging leveling plate 3, contrary to the above, and the effective purging width would be reduced. The scratch width is reduced.
然し乍ら、上記第１比較例においても、各延長板７が調
節機構を介して代掻整地板３に固定されていたため、上
記従来と同様の問題があった。However, in the first comparative example, each extension plate 7 was fixed to the plowing leveling plate 3 via an adjustment mechanism, so there was a problem similar to that of the conventional example.

や調節シャフトに大きな外力が作用することはなく、こ
れらが外力によって破損、損傷される惧れはない。The present invention is constructed as described above, and includes drive pulleys fixed to the main shaft at approximately the center in the width direction of the purge leveling plate, and driven pulleys provided on each left and right side of the purge leveling plate. Since a power transmission wrapping member connected to the extension plate via the adjustment shaft is hung between the pulley and the pulley, when doing plowing work, etc., the outer part of the extension plate on one side should be If an obstacle comes into contact with the
The wrapping member connected to the - side extension plate via the adjustment shaft slides against the driving pulley and the driven pulley, and the - side extension plate escapes to the other side. A large external force does not act on the extension plate or the adjustment shaft, and there is no risk that these will be damaged or damaged by the external force.

とはなく、これらが破損、損傷される惧れはない。Additionally, even when adjusting the movement of the extension plate, if the movement of the extension plate is blocked for some reason, the drive pulley that moves the blocked extension plate will idle relative to the wrapping member. Even in this case, no large external force is applied to the extension plate or the adjustment shaft connected thereto, and there is no fear that they will be damaged or damaged.

The operating force is well transmitted to the extension plate, and therefore the extension plate can be smoothly moved from side to side without fear of being twisted.
