A sickle bar mower is a type of agricultural implement used for cutting grass, hay, or other crops. It consists of a long, horizontal bar with small serrated blades, known as sickles, attached along its length. As the mower is pulled or pushed through the field, the sickles move back and forth in a reciprocating motion, cutting the crop close to the ground. These mowers are particularly well-suited for cutting tall grass, small grains, or delicate crops without causing significant damage.

Sickle bar mowers are often used in small-scale or traditional farming operations and are available in various sizes and configurations, including tractor-mounted and hand-operated versions. They are valued for their precision in cutting and their ability to handle a variety of crops with minimal damage.
