摘要：
A tillage implement has a gang of rotary spider tines, each spider tine having a center portion and a plurality of teeth forming a peripheral edge of the spider tine. Each tooth is rearwardly curving from the intended direction of rotation and has a curved leading edge and a curved trailing edge that taper to a rounded outward tip. A distal end of each tooth is angled relative to a tooth base to form a flared paddle such that the flared paddle is angled with respect to the tooth base and center portion of the spider tine. A first set of teeth have flared paddles angled in a first direction and a second set have flared paddles angled in a direction opposite said first direction, with the first set being alternately positioned with the second set in a circumferential pattern around the peripheral edge of the spider tine.
