摘要： An agricultural implement (1) for soil working, comprising a frame (10, 101, 10a, 10b, 10c, 10d, 10e), a number of ground-engaging tools (12, 13) carried by the frame, at least one rolling ground support (11a, 11b), the height position of which is adjustable relative to the frame, a height sensor (31) for contact-free measuring of the height position of the frame relative to a ground surface (G1), and a control unit (15), arranged to receive a signal from the height sensor (31) and to control the height position of the rolling ground support (11a, 11b). At least one of the tools (12, 13) is resilient relative to the frame (10, 101, 10a, 10b, 10c, 10d, 10e). A tool position sensor (32) is arranged to measure the orientation of the tool (12, 13), and the control unit (15) is arranged to receive a signal from the tool position sensor (32) and to calculate a work depth for said tool (12, 13) based on the signal from the height sensor (31) and based on the signal from the tool position sensor (32). Furthermore, a method of determining the work depth of a soil-working agricultural implement is shown.
