Abstract: A new chain harrow of improved performance with regard to effective harrowing and non-clogging is made up of V-shaped elements (as seen in plan) interlinked with the apex of one connected to the end of a respective arm of a more forward element. The elements are formed of unusually large diameter steel rod (e.g. about 16 mm instead of the prior thickness of about 11 mm) with relatively unusually large loops and with a horizontal apex loop that is an incomplete turn of about 270 degrees so as to provide for a specially effective sweeping and guiding action. Each arm is provided at its end with a respective tooth at the end of a respective vertical loop for interlinking with the horizontal loop of the forward element.
