In the harvesting of silage corn were tested several types of knives, counter plate and throwing blades for combine harvester JAGUAR produced by the manufacturer CLAAS, and their analogues. Both the original and analog spare parts were purchased on the German market at retail prices. According to experts of the chambers of Agriculture, the ratio of value of components from different manufacturers on the markets of most countries, as a rule, remains unchanged, so the results of comparative tests relevant to customers in all regions.

High wear resistance, the tests showed the ORIGINAL CLAAS knives for corn. After treatment 580 ha of residual coating knives-analogues did not exceed 5 mm with significant areas of "washing out" that allowed you to use them for further cleaning in area is not more than 180 hectares. the original knives for corn JAGUAR sharpness of the blades and the residual coating 14 mm preserved after processing 360 ha. Is allowed to use knives when cleaning another 840 hectares. Thus, the overall performance of the parts CLAAS amounted to 1,200 hectares against the 760 hectares analog of the blades. Taking into account the need for more frequent replacement of the overall costs of using non-original components was 33% higher than the CLAAS ORIGINAL.

Quickly offset the higher purchase price, and allows a longer service life of knives CLAAS ORIGINAL for green mass. If the analog parts were completely worn out after processing 332 hectares, the original knives remains operational during the cleaning of 543 hectares In operational costs when using analog parts was 28% higher. In addition, due to the small manufacturing tolerance knives for green mass CLAAS ORIGINAL increased the quality of work and service life of the machine, protecting the drum and bearings from damage.

Twice the efficiency demonstrated during testing of the counter blade CLAAS ORIGINAL. So, without replacing them was removed 720 ha 360 ha during the use of analogues. The total costs for each hectare removed the original blades were 33% lower.

High durability and reliability demonstrated, and throwing blades. If counterparts the overall performance was limited to the same period in 930 hectares of the original blades can be used for the treatment of 1400 ha. This is the area which, on average, removes harvester JAGUAR for the season.

According to the results of the test of German experts identified several key benefits of CLAAS ORIGINAL parts when operating forage harvester JAGUAR. First of all, we are talking about higher economic efficiency and preservation of the fully functional machines for a longer period of operation. Also original parts can reduce the cost of fuel and maintenance, provide more high quality grinding and maximum productivity when harvest.
