Soil cultivation device for depth loosening of soils which is movable in a moving direction relative to the soil, the device comprising: a device chassis or device frame, at least one supporting arm articulated with a first portion thereof to the device chassis or device frame so as to be pivotable up and down about a pivot axis stationary with respect to the device chassis or device frame, a driving device for driving the up and down movement of the at least one supporting arm, at least one piercing tool articulation device for each supporting arm by means of which at least one piercing tool can be articulated in a manner pivotable about a second pivot axis relative to the associated supporting arm to a second portion of the supporting arm in such a way that the piercing tool can be inserted into the soil during the downward movement of the supporting arm, and that the piercing tool articulation device is pivoted relative to the supporting arm and to the soil at least while the piercing tool is being inserted and the soil cultivation device is moved on in the moving direction so that the soil beneath the ground surface can be loosened, and at least one transmission mechanism connected between the piercing tool articulation device and a damper device for damping the relative movement between the piercing tool articulation device and the associated supporting arm at least partially, wherein the damper device comprises a body of an elastomeric material that is interposed between a holding element for fixing the damper device and an input element connected to the transmission mechanism so that on the initiation of a movement by said transmission mechanism, the holding element and the input element can move for damping under deformation of the elastomeric body, characterized in that a) a first side of the elastomeric body is fixedly connected to the holding element while being flatly supported on a holding surface of the holding element, and that a second side of the elastomeric body opposite the first side is fixedly connected to the input element while being flatly supported on a holding surface of the input element, and/or b) that the body of elastomeric material is elastically biased by means of a separate biasing device acting against said body. a device chassis or device frame, at least one supporting arm articulated with a first portion thereof to the device chassis or device frame so as to be pivotable up and down about a pivot axis stationary with respect to the device chassis or device frame, a driving device for driving the up and down movement of the at least one supporting arm, at least one piercing tool articulation device for each supporting arm by means of which at least one piercing tool can be articulated in a manner pivotable about a second pivot axis relative to the associated supporting arm to a second portion of the supporting arm in such a way that the piercing tool can be inserted into the soil during the downward movement of the supporting arm, and that the piercing tool articulation device is pivoted relative to the supporting arm and to the soil at least while the piercing tool is being inserted and the soil cultivation device is moved on in the moving direction so that the soil beneath the ground surface can be loosened, and at least one transmission mechanism connected between the piercing tool articulation device and a damper device for damping the relative movement between the piercing tool articulation device and the associated supporting arm at least partially, wherein the damper device comprises a body of an elastomeric material that is interposed between a holding element for fixing the damper device and an input element connected to the transmission mechanism so that on the initiation of a movement by said transmission mechanism, the holding element and the input element can move for damping under deformation of the elastomeric body, characterized in that a) a first side of the elastomeric body is fixedly connected to the holding element while being flatly supported on a holding surface of the holding element, and that a second side of the elastomeric body opposite the first side is fixedly connected to the input element while being flatly supported on a holding surface of the input element, and/or b) that the body of elastomeric material is elastically biased by means of a separate biasing device acting against said body. a) a first side of the elastomeric body is fixedly connected to the holding element while being flatly supported on a holding surface of the holding element, and that a second side of the elastomeric body opposite the first side is fixedly connected to the input element while being flatly supported on a holding surface of the input element, and/or b) that the body of elastomeric material is elastically biased by means of a separate biasing device acting against said body.
