Abstract
A tine device for a soil conditioning aeration machine capable of replacing a tine with another in a simple motion. The tine is mounted onto a driving portion through a coupler having an internal member. The internal member has a body portion capable of being inserted into the tine and the coupler retains the inserted tine through movable steel balls. The steel balls are freed by pushing an outer cylinder of the coupler against the force of a coiled spring so that the tine may be removed/mounted in a simple motion.
