In order to accelerate the process of drying of grass mowed for hay and haylage there are numerous technological treatments: multiple tedding, raking in rolls and turning rolls, mechanical impact on green forage in the process of mowing by the use of presses and windrow scarifiers. Presently mechanical maceration of green forage with mowing is popular. Papilionaceous feed plants are subjected to windrow presses and graminacenous plants to beating working systems. Analysis of various devices for acceleration of the drying process of green forage proves that they are quite complex and expensive on account of considerable material consumption. In order to eliminate the faults in the Russian Scientific and Research Fodder Institute of Wiliams a completely different windrow scarifier for the rotary mower KR-2.4 M was developed. It has a simple structure and it serves for acceleration of field drying of mowed grass in loose rolls. The paper presents the results of the research on a mower with an experimental windrow scarifier

In case of traditional harvesting methods the losses of perennial grass seeds may reach 45-50% of the biological yield in unfavourable weather conditions. The paper presents the results of comparative assessment efficiency of various methods of harvesting of perennial seed grass. It was found that the use of special devices and structures in combine harvesters allows increase of yield of technological mixture to the combine tank, degree of seed threshing to 93% and limit the losses of crop to 20-29%. Harvesting of seeds in non-waste technology with harvesting of the entire yield with later transport, drying, threshing and seeds cleaning in stationary devices results in reduction of losses by 5 to 10% but it leads to the increase of energy inputs by 24-25% in comparison to traditional with threshing method. Harvesting with a combing method of plant seeds on a trunk in „Невейки” technology results in the increase of the seeds harvesting to 86-98% of a biological yield.
