Abstract: A power-operated sickle for cutting agricultural plants and for preventing the cut stalk of the plant from coming in contact with reciprocating components of the sickle. The sickle includes a plurality of cutting teeth attached to a drive bar that is slidably retained on a stationary horizontally disposed sickle bar. A plurality of underside teeth are attached to the sickle bar and extend forwardly therefrom. A cover member is attached to the sickle bar and extends over covering the drive bar and other reciprocating components thereat. The cover member includes a plurality of upper teeth that extend over the underside teeth and sandwich the reciprocating cutting teeth therebetween. The cover member includes a semi-circular section extending between its attachment to the sickle bar and the upper teeth.

Abstract: A plow moldboard made of a plurality of sections which are reversible and interchangeable so that each moldboard section can alternatively serve as the leading edge of the moldboard in two different positions. Each section has substantially parallel top and bottom edges and substantially parallel side edges. Each section has a uniform curvature and also has two apertures for receiving a bolt therethrough and for fastening upon the plow frame.
