Abstract
A furrower having shares that are displaceable on a support pipe which is connected to a tool attachment socket by a swivel joint, that can be fastened in any position. The fastening place is effected by a clamping device which can be released against spring action by a manual knob or button. A clamping member within the head of the share is pressed by means of its clamping section against the support pipe. This clamping section can be released by pushing the manual knob inwards. Preferred places of attachment to the support pipe are defined by notches. Each notch can accommodate one share, the share being engaged with the notch by means of a notch pin.
