By the results of theoretical researches was obtained analytical expressions to determine the speed of the airflow in the deflector of pickup – grinder forages. By experimental researches the accuracy of the obtained analytical expressions verified. Results of experimental researches have shown that the optimum speed of the airflow in the deflector of pickup – grinder forages should be 15 m / s. In the picking up and grinding of grass by humidity 18-20% pick up-crusher has the performance 6.0 … 9.0 t / h, and it provides pick up and grinding rough fodder humidity 45-55% for production of haylage.
