ABSTRACT:
In an aspect, the invention is directed to a ripping mechanism for a vehicle. The ripping mechanism includes a support frame, a ripping member and an impact mechanism which is configured to reciprocate the ripping member forwardly and rearwardly. The impact mechanism is preferably a vibrator mechanism. In a particular embodiment, the ripping mechanism has a longitudinal axis, is mountable to the vehicle and is movable between a raised position and a lowered position. The ripping member has an engagement head that is configured for plowing a groove in the ground and that is pivotally supported on the support frame about a ripping member pivot axis that is positioned such that pivoting of the ripping member displaces the engagement head longitudinally. The impact mechanism is preferably a vibrator mechanism. The vibrator mechanism is connected to the ripping member wherein activation of the vibrator mechanism causes reciprocating pivoting movement of the ripping member.
