<p>A tine assembly comprising a plurality of individual tines, each tine with an arcuate shaped base section (104) and a blade section (106). Each time is mountable between a pair of hubs suds that each blade extends radially outward therefrom. The base portions are clamped, secured, or otherwise engaged between the hub assemblies. The blades may be positioned to be twisted in various angles about a line extending substantially radially outwards, by the use of wedge-shaped, arcuate blocks. The blocks and individual tines may be positioned in a multitude of different configurations to providing desired rotational positioning of the tine blade sections.</p> |
