ABSTRACT:
Supporting the forward end of a mobile frame is a rotatable drum having a number of sawtooth-shaped or beveled ribs extending circumferentially around the drum. Owing to the sawtooth configuration of the circumferential ribs, each rib opens a furrow having a sloping side and a vertical side. A plant supply tape is employed, one for each furrow to be formed, which has a series of resilient blocks secured to a nonstretchable flexible belt, the root ends of the plants to be transplanted being releasably held in the slits between adjacent blocks. A roller mechanism changes the direction of tape travel directly over the sloping side of the furrow being supplied with plants from the tape so that each slit is opened to deposit a plant on the sloping side of the furrow. A scraper blade, one for each furrow, extends downwardly from the frame to backfill the furrow immediately after several plants have been dropped therein.
