Abstract
The article considers the question of the performance increase of the innovative constructions of the bucletless rotary implements of the continuously operating earthmoving machines by improving the process of the rotor discharge from the excavated soil. The physical model has been designed and produced for the proposed design of the bucketless implement with the two-stage tray discharge and a possibility to change the design of the discharge assembly in the process of the study. The model testing methodology and experimental equipment used in this study will allow the perform the necessary set of tests to create the regression equations of the studied process and for optimization of the tray discharge assembly design.
