Results of extensive tests of a hanging brush grade equipped with track softeners and field soft devices

Abstract

The article presents the structure, technological work process, values of basic parameters, technical description, and results of field tests of a comprehensive suspended screed-leveler equipped with devices that can quickly and easily adjust the pressure on the soil and create a soft soil layer on the surface of the field. According to the results of the tests, the working depth of the trail softener was 19.6 cm and 19.3 cm. At speeds of 6-8 km/h, the performance of a comprehensive roller-leveler equipped with track softeners and a device that creates a soft soil layer on the surface of the field is 4.96-6.24 ha/h in the main time, the performance in the operational time is 3, 77-4.74 ha/h, fuel consumption was 4.0-4.4 kg/ha. These remarks confirm that the pilot copy of the comprehensive roller-leveller, equipped with track softeners and a device that creates a soft soil layer on the field surface, performed the specified technological process reliably and qualitatively, and its performance fully corresponds to the initial requirements.
