The aim of the work was to determine the quality of a new and used cultivator blade to assess the condition of the metal with the development of rejection norms of its variability in a magnetic parameter – coercive force using various types of equipment – coercimeters. The new cultivator blade shows the highest level of coercive force that is characteristic of its right and left parts and its decrease occurs towards the toe. After operation, variability is noted, characterised by both an increase and a decrease in the indicators of the coercive force. Rejection norms of the metal state, which determine the possibility of restoring a worn cultivator blade, which can also provide satisfactory indicators for their further use in operation, have been proposed. For restoration, it is recommended to use a cultivator blade made of low carbon steel, the zones of which should not change the level of the coercive force > 10.0% during operation. It is not recommended to restore those blades in which, after increasing the indicators, they then decreased to (< 5.0%) and are characterised by close values of the indicators.
