GROUND ENGAGING AGRICULTURAL TINE AND ASSOCIATED MOUNTING AND INDEXING SYSTEM

摘要

An agricultural implement has gangs of soil aerator tools. Each gang includesaset of integral multi-tine units mounted on a frame for rotation in unison.Each tine unithas a hub with tines. The hub has a first surface defining a first set ofindexing receiversand a second surface defining a second set of indexing receivers. At least oneindexingspacer separates each tine unit from the next tine unit. Keys of the indexingspacersassemble with selected ones of the first set of indexing receivers or thesecond set ofindexing receivers to establish and maintain a predetermined pattern ofrotational indexpositions among tine units in a group and groups in a gang. A method ofrotationallyindexing agricultural tools in an assembly. One method includes providing ashaft, tineunits, and indexing spacers. Assembly involves sliding a tine unit and anindexingspacer onto the shaft, and assembling in series the tine unit and the indexingspacer onthe shaft, such that the indexing spacer orients the tine unit to form anassembly.
