The article presents the results of laboratory experiments to determine the productivity and some other parameters of the disk working body, working  with the scheduler bucket in order to improve the process of leveling fields that meet the agrotechnical requirements of pre-sowing background.

Productivity, disk, bucket filling coefficient, disk diameter, drawing prism.
