The small blade for a reaper machine is a precision-engineered cutting component made typically from mild steel or high-quality steel alloys, designed to efficiently cut crops such as wheat, paddy, millet, sorghum, and other cereals. These blades are mounted on the cutter bar of the reaper and work in coordination with the machine’s rotary or reciprocating mechanism to provide clean, uniform cutting of crops at adjustable heights, usually ranging from 3 to 5 centimeters.
