Abstract

Abstract A kit for converting a conventional rake having one row of tines to one having two rows of tines in back-to-back relation. The kit comprises a straight attachment bar having sawteeth on one edge and three clamping plate assemblies, each of which consists of a pair of complemental plates shaped to have the back bar of a conventional rake snugly received therebetween, and a pair of bolts and nuts which clamp the plates toward each other. A shim is also provided for each plate assembly which adapts the latter to a conventional rake having a particular curvature in its back bar and tines.
