Abstract
The aim of this study was to compare the performance of conventional and stripping headers, which can be an alternative for cereal harvesting, in terms of technical and management aspects. For this purpose, grain looses, TA R IM B IL IM LE R I D ER G IS I J O U R N A L O F A G R IC U LT U R A L SC IE N C ES 1 6 (2 01 0) 2 42 -2 53 Bugday Hasadinda Kullanilan Klasik ve Yolucu Hasat Basliklarinin Performans Karsilastirmasi, Say et al T a r i m B i l i m l e r i D e r g i s i – J o u r n a l o f A g r i c u l t u r a l S c i e n c e s 16 (2010) 242-253 243 effective field capacity and fuel consumption values of both two headers were determined. Field tests were conducted based on split plots in randomized blocks that header (conventional and stripping), forward speed (5, 7 and 9 km h) and moisture content of grain (11 and 16%) were chosen as independent variables. It was obtained that the forward speed and the moisture content were effective on grain looses and fuel consumption statistically (P<0.01). In harvest with conventional header at 5 km h forward speed, total grain looses and fuel consumption were 0.79%, 10.4 l ha and 0.71%, 12.2 l ha for 11 and 16% moisture contents, respectively. Total grain looses decreased with increase in forward speed and moisture content in harvesting with stripping header. For stripping header, total grain looses ranged between 1.11-0.86% and 0.82%-0.59 for 11% and 16% moisture contents, respectively. Fuel consumption decreased with increasing forward speed, but it increased with increasing moisture content. These values varied from 6.4 to 8.0 l ha for high moisture content and varied from 7.6 to 8.8 l ha for low moisture content. Comparing the conventional header at ideal forward speed (5 km h) with the stripping header at highest forward speed (9 km h), it was found that the total losses were almost same for both two headers, the effective capacity was 153% higher and the fuel consumption was 32% less for stripping header.
