摘要： The cultivating element rock shaft has an extension actuating micro-switches in conjunction with a floating sensing arm. The micro-switches operate solenoids which control the valves connected to the hydraulic piston and cylinder assembly for raising and lowering the elements either manually or automatically.

摘要： An hydraulic ram is situated between the tillage tool and the frame and is normally fully extended and acts as a rigid link. The ram has a predetermined and adjustable pressure so that if an obstruction is encountered by the tool, it only retracts when the preset pressure is exceeded and then returns to the fully extended position as soon as the obstruction is passed. It can be used on machines such as discers, hoe drills, press drills or any ground working implement which includes tillage tools which are pivoted to the frame and which do not engage the ground by raising and lowering the frame. An adjustable pressure reducing valve is situated in the hydraulic line extending to the ram and senses the pressure downstream of the valve rather than the pressure upstream as is usual.

摘要： A depth control device is attached to agricultural implements such as cultivators, seed drills, discers and the like, in order to control, within pre-determined limits, the depth of penetration of the earth working components. It comprises firstly a ground or surface engaging sensing member extending forwardly of the framework and secondly, a sensor that is connected to the earth working components. Both of these sensors are connected to mechanism to raise and lower the earth working components which controls the depth of penetration thereof so that, for example, if uneven ground is encountered, the depth penetration is corrected and if the density changes of the ground being worked, thus affecting the suction, then once again depth penetration is corrected. Structure is provided to average out the effect of conditions changing the depth of penetration so that the desired average depth of penetration is maintained particularly in relatively wide machines. Switches are actuated by the sensors and these switches are connected to solenoids or solenoid valves which in turn operate the raising and lowering mechanism for the earth working components, the mechanism being operated either by hydraulic rams or reversible electric or hydrostatic motors.

摘要翻译： 液压柱塞位于耕作机和框架之间，通常完全伸展并作为刚性连杆。 压头具有预定和可调节的压力，使得如果工具遇到障碍物，则只有在超过预设压力时才会缩回，然后一旦阻塞通过就返回完全伸出位置。 它可以用于诸如变色器，锄头钻头，冲压钻头或任何地面作业工具的机器上，其包括通过升高和降低框架而枢转到框架并且不接合地面的耕作工具。 可调节的减压阀位于延伸到压头的液压管路中，并感测阀门下游的压力，而不是像往常一样上游的压力。
