Apparatus for providing a six-inch deep trench in a lawn surface, for the primary purpose of installing irrigation pipe for sprinkler systems. A trenching tool which includes a lower portion having two heavy steel blades and a hinge mechanism. The steel impact blades are sharpened at the bottom to accommodate a V configuration to enhance the downward penetrating action by the operator as he drives the blades into the ground until the desired 6" is reached. The operator then forces the handles together which separates or widens the bottom portion of the channel. The channel/trench is elongated for any distance the operator desires by repeatedly thrusting the tool into the lawn right next to the elongated section of the original opened trench.
Outil permettant de creuser une tranchée de 15 cm (6 po) dans un terrain gazonné dans le but d'installer les tuyaux d'irrigation de systèmes d'arrosage. Cet outil d'excavation de tranchées comporte une partie inférieure pourvue de deux lames d'acier épais et d'un mécanisme à charnière. Les lames à percussion en acier sont aiguisées au bas de manière à présenter une configuration en V, ce qui permet à l'opérateur d'enfoncer plus facilement les lames dans le sol jusqu'à la profondeur souhaitée de 15 cm (6 po). L'opérateur rapproche alors les poignées afin d'élargir la partie inférieure de la tranchée. Il peut allonger la tranchée sur la distance voulue en enfonçant l'outil à répétition dans le sol à partir de la partie de la tranchée déjà pratiquée.
