ABSTRACT:
A chisel plow point consisting of a unitary tip section, a tip extender portion extending in the direction opposite to that of the tip section and conforming to and adapted to overlie the end section of a moldboard to present a working surface that turns and throws the soil during the plowing operation, whereby the moldboard is protected against wearing engagement with the soil, a recess behind the extender portion shaped to receive an end section of the moldboard, and an adapter for attachment of the plow point to the plow frame. The tip extender is approximately equal in length to the length of the tip section, is thinner in cross-section than the tip section and has a generally concave configuration to conform with the plow moldboard.
