The present invention relates to a agricultural tractor propelled or self-propelled weeding machine for mechanically and mechanically controlling undesired vegetation, or weed plants in open ground, rows of cultivated crops such as vegetable crops and herbs. More in particular, the invention relates to a weeding machine which is equipped with a weeding element with torsion weeding teeth. The weeding machine of the above-described type according to the invention, characterized in that the weeding machine comprises at least one weeding element for holding at least two torsion weeding teeth, which weeding element for this purpose is provided with two arms pivotable independently of one pivot axis or each pivot axis, which arms are provided with fastening means for attaching at least one torsion tine tooth to each arm, which arms are mutually coupled by a spring element with an adjustable spring force. The advantage of a weeding machine with a weeding element according to these characteristics is that the processing intensity of the torsion weeding teeth can be adjusted to the working conditions in a user-friendly manner. The invention also relates to a weeding element for holding at least two torsion weeding teeth for attachment to a weeding machine, wherein the weeding element is characterized in that it is provided with two arms pivotable independently of one axis or each about an axis, which arms are provided with fixing means for attaching at least one torsion wheel tooth to each arm, which arms are mutually coupled by a spring element with an adjustable spring forceDe onderhavige uitvinding heeft betrekking op een door een landbouwtractor voortbewogen of zelfrijdende wiedmachine voor het machinaal en mechanisch bestrijden van ongewenste vegetatie, cq onkruidplantjes in vollegronds, op rijen geteelde cultuurgewassen zoals groentegewassen en kruiden. Meer in het bijzonder heeft de uitvinding betrekking op een wiedmachine die is uitgerust met een wiedelement met tors
