ANNOTATION
The article considers comparative tests of a chisel- cultivator with elastic tines. In economic tests, traction resistance, the quality of soil crumbling, the uniformity of the depth of cultivation, the ridgedness of the surface and bottom of tillage, and the mass of plant residues and weeds enveloping the working bodies along the length of the rut were determined.
Extensive tests have shown that the experimental chisel-cultivator has both qualitative and energy indicators higher than those of the serial ChKU-4A.
Key words: working body, rack, chisel -cultivator, spiral elastic rack, chisel implements, experimental chisel-cultivator, traction resistance.


INTRODUCTION

One of the ways to increase the efficiency and productivity, as well as the reliability of chisel implements in pre-sowing tillage is to improve the design of their working bodies. It should be noted that in the recent period there have been significant changes in the energy base of agriculture, energy-saturated high-speed tractors have been created and are increasingly being used . At the same time, individual agricultural implements and their working bodies remained the same, this also applies to the chisel cultivator. In the cotton-sowing zone, chisel-cultivators are the main tools for loosening the soil after leaching and reserve irrigation.

Recently, both in our country and abroad , the working bodies of chisel-cultivators and other tillage machines are equipped with spring-safety or elastic racks. According to many researchers , the use of such racks leads to a decrease in the traction resistance of the tool, provides the best quality indicators of its work, and eliminates breakage of the working bodies. / 1-6 /
Despite this, the working bodies of cotton chisel cultivators ChKU-4 and ChKU-4A still have rigid racks.
In this regard, we conducted a scientific, technical and patent review of the leading countries producing chisel tools, and based on its results, we chose the most promising version of elastic racks. /7/
It consists of a carrier frame 1, pneumatic wheels 6, an extension frame 4, a towing device 2, elastic racks with working bodies 5 and a mechanism for transferring 3 from the transport position to the working position and vice versa (Fig. 1)
