Abstract

1. Method for controlling the working depth of sowing coulters (3) of seed drills (2), wherein a probing device (6) probes the ground surface (4) and generates appropriate signals (S1 , S2 ,... Si ) which are evaluated in an evaluation circuit and are used for ascertaining the working depth (AT ), characterised in that a value (SM ) is ascertained from the signals (S1 , S2 ... Si ), which takes account of the clods (5) lying on the ground surface (4) and is characteristic of the ground profile, such value corresponding to a value which would be obtained when be obtained when probing an ideally smoothened ground surface, and in that the working depth (AT ) is determined in dependence upon this characteristic value.
