ABSTRACT
In this article, the analysis of field leveling and compacting machines used in the preparation of land for planting seeds and the research conducted on them, the improvement of the technological work process of the leveler and the justification of its parameters, the improvement of work quality and productivity in the preparation of land for planting seeds of seeds and other crops are discussed.
INTRODUCTION.
Today, the development and use of energy-resource-efficient, high-quality and productive machines in the cultivation of agricultural crops is taking a leading place in the world. "Currently, the cultivated area in the world before planting in the soil is 1.6 billion. hectare", the creation and production of energy-resource-efficient, high-quality and productive machines and devices used in the cultivation of land before planting is considered an important task. From this point of view, there is a need to pay special attention to the development of the technical means used in processing the land before planting.
In Uzbekistan, one of the most important tasks in preparing the land for planting seeds of seeds and other crops is early fertilization of the fields. If this agrotechnical event is carried out on time, long-term storage of moisture accumulated in the soil during the autumn-winter period is achieved, the loss of sprouting weeds and salt in the soil does not rise to the surface of the field is ensured.
Delayed fertilization in early spring causes loss of soil moisture, looseness of the field surface, and hardening of the plow layer. As a result, the possibility of high-quality sowing of seeds and harvesting of seeds is lost. For this reason, early spring fertilization of the fields should be started as soon as 8-10 cm of soil surface layer is formed and should be completed within 2-3 days.
MAIN PART
Immediately before planting, the lands where the seeds are harvested due to the natural moisture in the soil are fertilized along with leveling (grinding), and the lands that have been given moisture and washed with salt are softened 1-2 times with chisel-cultivators, and the trail is ground and fertilized 2-3 times in one go. .

Ws,
Based on the above, the main agrotechnical requirements for land clearing are as follows
- the paved area should have a flat surface, that is, the mean square deviation of the unevenness of the field surface in the transverse and longitudinal directions should not exceed ±2 cm every 5 m;
- the density of the soil in the 5-15 cm layer over the entire area should be 1.1-1.2 g/cm3 on average;
