The invention relates to a soil-working implement (1, 2) for subsoiling (22), having a series of carrying arms (25), of which each is mounted by way of a first region, in particular a first end region, on an implement frame (20) or an implement chassis such that it can be pivoted up and down about a first pivot axis (26), having a crankshaft (34) with at least one crankshaft journal (38), having in each case at least one cutting tool articulation device (30) for articulating a cutting tool (32) on a second region, in particular a second end region, of each carrying arm (25), and having at least one crank connecting device (29) per carrying arm (25), this device connecting the cutting tool articulation device (30) to the at least one crankshaft journal (38) of the crankshaft (34) for the purpose of driving the up and down movement guided by the carrying arm (25). In order to improve the soil-working implement such that adverse effects of the cutting tools striking against obstructions can be minimized, and nevertheless smaller moving masses can be provided, it is proposed that the crank connecting device (29) has an uncoupling device (42) which, at least in the case of overloading between the crankshaft (34) and the cutting tool articulation device (30), allows relative movement of the cutting tool articulation device (30) in the direction of the crankshaft journal (38).
