Exploitation parameters of silage combine during silage corn harvesting | Eksploatacioni parametri silažnih kombajna pri ubiranju kukuruza za siliranje

English. This paper presents exploitation results of two types of silage combines in the same working conditions during whole corn stalk harvesting: Krone BIG X-V8 and John Deere 6810. Both of combines present contemporary machines designed with high production capacity. Operational width for Krone BIG X-V8 was 10 rows and for John Deere 6 rows, what coused difference in realized capacity. Averege mass efficiency by Krone BIG X-V8 and John Deere were 156.59 t/h and 104.39 t/h, respectively. Area efficiency by Krone BIG X-V8 and John Deere were 2.79 ha/h and 1.41 ha/h, respectively. The quality of cutting was satisfied for both tested combines. Therefore, adjusted cutting length for Krone BIG X-V8 of 10 mm and for John Deere 6810 of 11 mm, were realized with average values of 9.84 mm and 12.3 mm, respectively. Both tested types of combines are suitable for big farms in domestic agriculture.

Serbian. U radu su prikazani rezultati ispitivanja dva tipa silažnih kombajna u istim uslovima rada pri ubiranju cele stabljike kukuruza : Krone BIG X – V8 i John Deere 6810.Oba kombajna su savremene konstrukcije i projektovano visokog kapaciteta. Kombajn Krone je radnog zahvata 10 redova,a John Deere 6 redova,te su i analogno tome ostvareni kapaciteti različiti. Sa kombajnom Krone ostvaren je prosečni maseni učinak od 156,59 t/h,a sa John Deere-om od 104,39 t/h.Površinski učinak sa kombajnom krone ostvaren je od 2,79 ha/h , a sa John Deereom 1,41 ha/h.Kvalitet seckanja je zadovoljavajući kod oba kombajna. Podešena dužina seckanja kod kombajna Krone na 10 mm ostvarena je,prosečno od 9,84 mm. Sa kombajnom John Deere podešena dužina seckanja na 11 mm ostvarena je, prosečno na 12,3 mm. Oba ispitivana tipa kombajna pogodna su za velike farme u našoj poljoprivredi.
