A device for uprooting a plant comprises a lever (12) having a handle at one end, a pair of jaws (16, 18) at the other end, for gripping a plant stem, and a foot formation (14) extending transversely from said other end. The jaw (16) is fixed to the foot formation 14 and the jaw (18) is fixed to the lower end of the lever (12). When the device is placed in position with the jaws on opposite sides of the stem of a plant, and the lever (12) pulled, the jaws (16, 18) close onto the plant stem to grip the stem and, when the lever is pulled further, the device pivots about a fulcrum that is formed where the foot formation contacts the soil surface, pulling the plant roots and all from the soil.

La présente invention concerne un dispositif permettant de déraciner une plante, qui comprend un levier (12) muni d'une poignée à l'une de ses extrémités, à l'autre d'une paire de mâchoires (16, 18) faites pour agripper la tige d'une plante, et un sabot (14) disposé transversalement par rapport à cette autre extrémité. La mâchoire (16) est solidaire du sabot (14) et la mâchoire (18) est fixée sur l'extrémité inférieure du levier (12). Lorsque le dispositif est présenté avec les mâchoires de part et d'autre de la tige de la plante, et que l'on tire sur le levier (12), les mâchoires (16, 18) se referment sur la tige et la happent. Lorsque l'on continue de tirer le levier, le dispositif pivote autour d'un point d'articulation formé là où le sabot touche la surface du sol, ce qui a pour effet de déraciner la plante et de l'extraire dans sa totalité.
