A rotary tool for marking a straight or curved groove in a garden in which seeds are to be laid. The tool includes an enclosed drum, which may be filled with water, with the drum rotatably mounted to a yoke fixed to a handle. A rim centrally fitted with an external V-shaped projecting flange is detachably fastened to the cylindrical drum wall. Alternate detachable rims are provided with each rim fitted with a flange of a different size so as to each form a groove of a different depth when rolled across a garden seed bed.
