Reduced tillage forms a subgroup of conservation tillage. In this system, chisel or disc tools are
generally used for primary soil tillage, and milling machines, disc tools or cultivators are used for
secondary soil tillage and seedbed preparation. The entire area is tillaged so that the plant residues
are on the soil surface and prone to the surface. It provides significant fuel and energy savings
compared to conventional tillage due to less machine traffic. In order to ensure sustainability,
conservation tillage (using a chisel instead of the plow that works by turning the soil) as an alternative
to conventional tillage and the development of agricultural tools and machines used for this purpose
have gained great importance. Chisel is a soil cultivation tool widely used in stubble destruction and
conservation tillage system. It is known that the chisel provides significant savings in terms of fuel
consumption compared to the plow. For a chisel construction that can operate at an optimal level, the
basic requirement is to have optimal material quality, optimal weight and optimal cost. In this
research, the physical and chemical processes of chisel tines produced as cast steel were examined.
It is of primary importance that it provides minimum fuel consumption with its optimal chemical
content, easy mounting to the chassis, unbreakable model structure and angles. A casting and
agricultural machinery company that helped with the study was visited and the GS-52 steel casting
process, which is widely used for chisel tines in our country, was examined and tensile, yield and
rupture tests were performed. As a result, it has been observed that a better construction can be
created by changing the chemical content of GS-52 steel. Different trials to be carried out as the
continuation of the research will help determine the optimal structure of the chisel tines.
