Abstract

The harrow includes a series of sleeves each having a plurality of teeth and telescoped non-rotatably over a rod which is rotatably journaled by laterally spaced bearings supported by mounting arms which, in turn, are attached to a tool bar. The teeth roll over the ground and pulverize and level the soil as the tool bar is pulled forwardly. The toothed sleeves may be laterally positioned as necessary on the rod to enable the bearings and the mounting arms to be located laterally as required to permit attachment of the arms to any particular tool bar. The tool bar is supported by parallel links which may be adjusted upwardly or downwardly by manually operable jacks in order to change the operating height of the harrow, the jacks being connected to the links in such a manner as to enable the links to float upwardly or downwardly in the event the harrow encounters a rise or falls into a valley.
