The paper presents a device with chisel-type working parts for measuring the tensile strength independently on each working parts or on various groups of working parts, equipped with devices designed for separate measurement, intended for complex research of agricultural machinery in interaction with the soil. The proposed solution is new and is based on flexibility and allows the mounting of various working parts in various positions. The functional model developed with elements of novelty and innovation led to the elaboration of a patent application, which refers to a load-bearing structure modulated with multiple applications for tillage machines, on which active parts are mounted in different working variants, in order to extension of the period of use, depending on the size of the agricultural exploitations and the power of the tractor. The modular design of the device will allow the development of a range of flexible cultivators that can be configured to in order to use power sources (tractors) from 30 hp to 90 hp, allowing the manufacturer to expand its market.
