  • Patent number: 4407371
    Abstract: Apparatus is disclosed which facilitates the ready attachment and detachment of coulters to a standard seed planting device. The seed planting device is typically of a type that is towed behind a tractor and automatically furrows the ground, deposits the seeds in the furrows at spaced intervals and covers the seeds over. The disclosed apparatus allows an operator to readily attach a plurality of coulters to this planting device thereby enabling its use for minimum-till, or no-till farming operations. The coulters are attached to a framework which is bolted onto the planter frame. This framework may be readily removed as a unit to enable the use of the planter in its standard condition. The framework locates the coulters in a forwardmost direction to increase the downward force on same so as to enable no-till farming operations with hard or rocky soil. This location of the coulters eliminates the need for ballast weights.
