Abstract
Polymeric materials are advised to be used in the construction of operating devices for energy-saving soil cultivation. Purpose of work is to develop the design of new operating devices with polymer materials. Development of the design of new operating devices with polymeric materials is carried out by replacing part of the metal parts with ultra-high molecular polyethylene of low density. New operating devices carry out several technological operations in one pass. The design of the new operating device contains a rack with a chisel for deep tillage. The front of the rack is equipped with removable plowshare blades. Clod crusher with a possibility of movement and thrust plate are located at the chisel. In the upper part of the rack the ripper for surface tillage is mounted with the possibility of replacing. Ultra-high molecular polyethylene of low-density was installed on the chisel and clod crusher of the tillage operating device, the thrust plate and the ripper for surface tillage are made entirely of polymeric material. Decrease to 18.28% of draught resistance of the operating device with polymeric materials was established.

There is compliance with the agrotechnical requirements of the operating device with polymeric materials, the preservation of plant and crop residues of 65-76%, ridgeness of 6.9-7.9 cm, the quality of crumbling of 87.4-94.8% with fractions of less than 50 mm in size. It ensures the fulfillment of the specified depth of soil cultivation (25-35 cm) by operating device with polymeric materials with allowable deviation
Summary
In engineering polymeric materials are becoming more widespread. Engineering is one of the largest consumers of metal. The low weight and low resistance of the processed medium to polymeric materials allows them to be used in the design of operating devices for energy-saving soil cultivation. There is unlimited adaptation of the properties of polymers based on composite materials that can be used in many engineering structures. Field studies have shown the durability of the elements of the tillage operating device, made of polymer based on composite materials, under difficult working conditions compared to those made of alloy steel. The use of ultra-high molecular weight polyethylene can solve the problems of adherence, wear and corrosion on plows, cultivators and other tillage machines Due to their low density and high endurance, the operating devices of ultra-high molecular polyethylene can compete with ones made of low-strength structural steels. Purpose of work is to develop the design of new operating devices with polymeric materials
