Vibratory Plow
A vibratory plow vibrates a few thousand times per minute. This allows it to slice through soil like a knife through cake. It allows direct burial cable to be laid but not larger than 32mm. For larger pipes see TrenchingEquipment and HorizontalDirectionaldrilling (HDD) http://www.americanaugers.com/www/docs/113.54 attachment:vibratoryPlow.jpeg
