Patent

CA 2527531

A tubular drawbar having at each end thereof a pair of spaced apart tab members integrally attached to one side of the drawbar. In an assembly position, when harrow hooks for supporting a harrowing section are initially placed onto the drawbar, the tab members are positioned on a side of the drawbar distal to that of the towing vehicle. Once the harrow hooks have been placed, the drawbar is then rotated to assume a working position, whereby each of the pair of spaced apart tab members likewise also rotate to assume a position proximal to that of the towing vehicle, thereby retaining the outermost harrow hooks securely therebetween, so that the harrowing section cannot become unhooked during use. Coupling means are also provided on a side of the drawbar, whereby the drawbar and harrowing section can be connected to a vehicle for towing.
