Abstract
An actuating mechanism (20) for a ground-engaging tool is arranged as a swinging parallelogram such that the tool has varying components of velocity in the horizontal and vertical directions. The mechanism is synchronized such that the tool has a rearwardly-directed velocity component substantially equal to the forward ground speed of the frame, when the tool is in the vicinity of its bottom dead center position. Hence, the tool has a substantially-zero net horizontal velocity as it engages the ground. The tool may include a burner head (25) and/or an injector mechanism (26) for planting a pneumatically-delivered seed-vermiculite mixture through a sheet of imperforate plastic mulch.
