Abstract:

A seedling transfer tool including a flexible inverted U-shaped blade assembly in an essentially inverted U-shaped configuration with two generally parallel fingers. Each finger has a U-shaped lower end terminating in a point and facing arcuate recesses at its upper end. A central section is provided having a generally semi-circular cross-section between its upper and lower ends. The blade assembly also has a downwardly facing U-shaped intermediate section which couples the fingers with a central aperture therethrough. The axis of the intermediate section is at a right angle from the axes of the central sections of the fingers. A screw extends through the apertures of the blade assembly and cylinder coupling the blade assembly and cylinder.
