Use of machinery of the improvement of pastures

The use of machinery for improving pastures was considered necessary in the recent years. The reasons that imposed their usage on one hand was the increase of the work volume in the pastures (cultivating, improving and harvesting works) and on the other the need of reducing the exploitation time as well as the total cost of each work. The rapid development of modern machinery provides us with the possibility to select the right machine aiming at the quick and suitable exploitation on one hand and the reduction of the cost of each work in the pastures on the other. One of the modern machines that can be used for the improvement of pastures (removal of shrubs) is the head with a rotating chain (cutting or crushing mechanism). The machine is adjusted easily on the tractor motorized by it. In this paperwork was studied the performance of the above machine and was calculated the hourly operation cost in order to draw out conclusions (production cost), able to help out the forest praxis as much as for the quality as well as for the reduction of  he cost of the above works.
