As this Manual Rolling Dibbler Tool is pushed down a row, the outward-facing aluminum spikes (or dibbles) on the rim of the tool's wheel(s) punch holes in the soil (or the plastic-mulch liner) into which transplants will be set. Sixteen 21/2-inch-long, 1-inch-diameter dibbles are stored (facing inward) in each wheel. Equidistant in-row plant spacing (from 3 to 41 inches apart) will depend on how many of the dibblers are re-attached to face outward. The tool's handle is offset to one side so the user does not tread on the just-marked row. Four models are available: one-person single wheeled, one-person double wheeled, one-person infinite (multiple) wheeled, and two-person infinite wheeled.)
