Transplanter with synchronized plant drop

Abstract

An agricultural planter has a carousel-type distribution unit for handling and planting plants. The distribution unit has a rotatably driven carousel containing a plurality of cups adapted to hold plants. The cups are operable to release plants into a conveyance channel for guiding the plants into a hollow plowshare. An ejector foot expels the plants from the hollow plowshare into a soil furrow. A drive mechanism drives the distribution unit to rotate the carousel, release plants into the conveyance channel, and expel plants from the hollow plowshare. The drive mechanism in one embodiment includes a ratcheting arm connected to a drive shaft that drives the distribution unit, and a linear actuator connected to the ratcheting arm. A positioning system determines a location of the planter in a field, and a controller activates the linear actuator to rotate the ratcheting arm when the planter reaches a tripping position in the field.
