摘要： A cover crop termination system includes a smooth drum and a crimping arm assembly operatively connected to the drum through a cam mechanism including a cam follower. The crimping arm assembly includes a plurality of crimping assemblies having crimping bars which crimp the cover crop after it has been rolled in order to prevent resprouting of the crop.

摘要： An apparatus and method are provided for continuously measuring the soil strength on-the-fly and at different depths. The apparatus includes a downwardly extending probe having an impedance sensor mounted on a leading edge thereof so as to be impacted by the soil as the probe is moved in a horizontal direction therethrough. A reciprocating drive is also provided which is effective for simultaneously oscillating the probe in an up and down movement while it is passing horizontally through the soil. The mechanical impedance exerted upon the sensor is then measured as the probe is passed both horizontally and up and down through said soil, thereby providing a continuous depth-variable profile of the soil strength over a large area.
摘要翻译：提供了一种用于在飞行中和不同深度连续测量土壤强度的装置和方法。该装置包括向下延伸的探头，其具有安装在其前缘上的阻抗传感器，以便当探头沿水平方向移动时被土壤冲击。还提供往复式驱动器，其有效地在水平地穿过土壤的同时使探头在上下运动中摆动。然后，当探头水平和上下通过所述土壤时，测量施加在传感器上的机械阻抗，从而在大面积上提供连续的深度可变的土壤强度分布。

摘要： Cover crops may be rolled and crimped using an apparatus which may be rolled across a field at a relatively high speed without excessive vibration. The apparatus includes a substantially cylindrical drum which has a plurality of rows of outwardly extending blades projecting therefrom. The blades may be wave-shaped, curved, substantially straight and discontinuous, blades paired with a plurality of spaced apart outwardly extending rings, or combinations thereof. In use as the apparatus is rolled across a field having a crop thereon, the blades contact and crimp the stalks of the crop, effectively killing the plant.
摘要翻译：覆盖作物可以使用可以以相对高的速度在田间上滚动而不会过度振动的装置来卷起和卷曲。该装置包括一个基本上圆柱形的鼓，其具有从其突出的多排向外延伸的叶片。叶片可以是波形的，弯曲的，基本上直的和不连续的，与多个间隔开的向外延伸的环或其组合成对的叶片。在使用中，当装置在其上具有作物的田地上滚动时，叶片接触并卷曲作物的茎，有效地杀死植物。
