ABSTRACT:
A flexible spike-tooth harrow having a plurality of tooth-supporting angles spaced fore-and-aft by connecting structure including reversible link straps having opposed edge surfaces on one end thereof tapered with respect to the axis of the strap at differing angles. A selected one of the edges is positioned against the top side of the angle to maintain the spikes in a preselected working attitude. By simply reversing the strap with respect to its longitudinal axis, the working angle of the spikes can be changed.
