The article discusses the efficiency of the cow mechanical driver milking cows in side-by-side parlours 2 x 10. If the mechanical driver is not used, the animals must be driven by cow tenders – cow drivers and milkers, but it causes considerable consumption of work. The research has been carried out on the training and research farm of the Latvia University of Agriculture “Vecauce” where in 2015 the light type mechanical cow driver Cow Mover M of the company DeLaval was introduced. For this purpose the cow milking procedure was timed before using the mechanical driver as well as about after two years of its exploitation. In the research it was stated that usage of the mechanical driver increases the cow crowding in the waiting yard up to 1.41.5 animals calculating per one m 2 of the yard area what is within the admissible limits. Therefore, the cow movement from the waiting yard to the milking places becomes faster increasing the productivity of milking from 79 to 82 cows per hour. Besides, the consumption of work of people engaged in milking decreases by 36 %. The calculations show that on the training and research farm of the Latvia University of Agriculture “Vecauce” introduction of the cow mechanical driver paid back within less than a year.
