<p>UNDERCUTTER SEED PLANTER An undercutter seed planter in the form of an elongated tubular seed delivery member adapted to be pulled beneath the soil behind the blade of an undercutter plow. An air metering system supplies seeds to the seed delivery member and such seeds are released at preselected intervals beneath the soil surface from a discharge opening at the member's trailing end. The trailing end portion of the member is formed to create a V-shaped channel to receive the discharged seeds, and a gage wheel assembly connected to the member's trailing end rides upon the surface of the soil and maintains the seed discharge opening at a predetermined distance beneath that surface. A two-way hinge connects the leading end of the seed delivery member to the undercutter plow to permit vertical and horizontal movement of the member's trailing end with respect to the plow.</p> |
