ABSTRACT:
Equipment for drilling a row of equidistant holes comprises a carriage attached to a tractor and two earth augers rotated about their axes by the tractor power-take-off through transmission means. The augers are fastened in opposite alignment to a horizontal axle which is mounted in bearings on the carriage and is rotated by one of the road wheels through a chain drive causing the two augers to rotate about the axle in a plane parallel to the direction of travel. The rotating augers enter the soil alternately and drill equidistant holes during progress of the tractor and the carriage.
