**Abstract**

Agricultural machinery expose to wear and corrosion. This damage results from dealing with varying conditions, such as plant moisture, density of plants, soil types, and environmental condition in the field; therefore, this damage leads to an increase in energy consumption, production losses, and a decrease in the lifetime service of reciprocating mower knives. There are many studies that have identified solutions that can be used to increase the life span of agricultural machinery by reducing the chemical corrosion of agricultural machinery. The methods used to reduce chemical corrosion in agricultural machinery can be summarized by selecting new resistant materials, using paint, and using corrosion inhibitors.
