Abstract :It is estimated that the world population will be ten billion in 2050, and Türkiye’s population will be 105 million. In order to supply the nutritional needs of the increasing population, new techniques, machine usage/mechanization and technologies are needed in agricultural production. In order for plant production to be conducted at the desired efficiency, the usage of machinery is one of top priority, and the first and most intensive stage is tillage. As a result of the contact and interaction with the soil of the machines used in tillage, some negative situations such as abrasion occur. In order to reduce wear as much as possible, value-added processes are applied to the tillage active elements. The most basic process is to provide the hardness values at the technically desired level by applying regional or general heat treatment to the active elements. The hardness limits of the machines are specified in the Agricultural Machinery and Tractors Test Principles. In this study, the hardness values obtained as a result of the static hardness test conducted in accordance with the standards on 469 active elements belonging to different types of tillage machines were evaluated. The hardness values of the tillage elements of these machines, such as shares, discs, teeth and blades, were examined and the average hardness and standard deviation values were calculated. According to the results, shares of the mouldboard plows (50.7±3.2 HR-C), discs of disc plows (48.5±2.1 HR-C), discs of disc harrows (47.8±2.4 HR-C) and theet of toothed harrows (47.78±2.4 HR-C) are within the limits specified in the principles. The cultivator shares (41.2±6.0 HR-C), subsoiler shares (42.3±3.8 HR-C) and rotary tiller blades (43.8±2.8 HR-C) values are below the limits specified in the principles.
