    摘要： An agricultural implement (1) comprises at least one soil-working tool (10) and at least one tool (11) with mainly a levelling function, arranged to work soil (100) across which the agricultural implement is moved. The agricultural implement further comprises a surface evenness sensor (20) for sensing a surface evenness of said soil (100) after being worked by said soil- working tool (10) and levelled by said levelling tool (11) as well as an indicating means (23) connected to the surface evenness sensor (20) and arranged to provide an indication of said surface evenness.

    摘要： The invention relates to an adjusting device for an agricultural machine, comprising at least one tool (3, 20) for working the soil, and at least one power member (12) for adjusting the tool (3, 20) in relation to the soil (6). A sensor (16) interacting with the tool (3, 20) detects soil (7, 22) displaced by the tool (3, 20), and a control unit (15) coupled to the sensor (16) controls the power member (12) in accordance with information received from the sensor (16).

    摘要： A distance sensing system (10) includes an ultrasonic transducer (XM1), a transceiver (12) and a microcontroller-based signal processing unit (14). The transducer (12) periodically generates and directs towards the terrain a dual frequency ultrasonic signal. Echo signals from the ground and/or any intervening crop or trash are reflected back to the transducer (12) and are processed. The system generates amplified and filtered echo envelope signals. Leading and trailing edge times are determined as the times the echo signals cross a threshold value which is a certain proportion of a maximum echo amplitude value. A near distance value is derived from the leading edge time of the first echo which exceeds a minimum amplitude. A far distance value is determined as the trailing edge time of the last echo signal which has an amplitude which exceeds a certain value. Multiple echo time and amplitude values are derived from the maximum amplitude echo. These values are used to prevent echoes which occur after the multiple echo time with less than a certain amplitude from being used in the determination of the far distance value. This far distance value represents the distance to ground and weaker, earlier echoes from trash or crop and later, multiple echoes may be ignored.

    摘要： A control system (30) for residue management with an agricultural implement (10) is disclosed. The control system (30): at least one image sensor (74, 78) mounted to the agricultural implement (10) to capture a first image of an area (76, 80) of ground ahead of or behind the agricultural tillage implement (10); a computing device that determines an indicator of residue coverage on the area (76, 80) of ground; wherein the computing device further determines if the indicator is within a regulatory standard addressing erosion that specifies a target percent coverage; wherein the computing device further determines an effect of an operation on the residue coverage based upon the determined indicator; and wherein the agricultural implement (10) changes one or more aspects of a subsequent or on-the-go ground engaging operation on the area (76, 80) of ground based upon the effect and based upon the determined indicator. Further, a method (200) for residue management for an agricultural implement (10) with at least one image sensor (74, 78) is disclosed.
