Abstract: A tractor towed seedling transplanter includes a main frame with a pair of canted rear wheels, a rearwardly facing operator's seat and a tray for storing a supply of seedlings to be transplanted. A power take-off from the wheels operates a rotary metering turret supporting a plurality of clam shell type hopper cups which receive individual seedling plants and are opened in proper timed relation by an adjustable cam to deposit individual plants in a vertically disposed feed tube having a lower end positioned above a furrow opened in the soil by a plow positioned forwardly of the canted rear wheels. Adjustment of the cam means permits an accurate release of the seedling plants from the clam shell hopper cups to properly discharge the seedlings into the feed tube for discharge into the furrow which is closed over the root clumps of the seedlings by the canted rear wheels.
