<p>A spiker blade for use on a turf spiker assembly to break and ventilate a ground surface thereby facilitating penetration of air, water and nutrient through the surface. The spiker blade has a tooth profile with a trailing edge having a counterdepression segment. The counterdepression segment functions to create a ground surface depression into which ruffled material kicked up by the tooth during spiking may be deposited. As a result, the ground surface after spiking has taken place is maintained relatively smooth with an unruffled appearance.</p> |
