Özet
Bu çalısmada, klasik biçerdöver baslığıyla tahıl hasadına alternatif olabilecek yolucu baslığın buğday hasadında teknik ve isletmecilik yönünden karsılastırılması hedeflenmistir. Bu amaçla, her iki baslıkla hasada ait dane kaybı, gerçek tarla kapasitesi ve yakıt tüketimi değerleri belirlenmistir. Tarla denemeleri, hasat baslığı (klasik ve yolucu), biçerdöver ilerleme hızı (5, 7 ve 9 km $h^ {-1}$) ve ürün dane neminin (% 11 ve % 16) faktör olarak seçildiği tesadüf bloklarında bölünmüs parseller deneme desenine göre yürütülmüstür. Denemeler sonucunda ilerleme hızı ve dane neminin dane kayıpları ve yakıt tüketimi üzerinde istatistiksel olarak etkili olduğu belirlenmistir (P<0.01). Klasik baslıkla hasatta 5 km $h^ {-1}$ ilerleme hızında %11 nem içeriğinde toplam dane kaybı %0.79, yakıt tüketimi 10.4 l $ha^ {-1}$ bulunurken, % 16 nem içeriğinde toplam dane kaybı %0.71ve yakıt tüketimi ise 12.2 l $ha^ {-1}$ olarak saptanmıstır. Yolucu baslıkla hasatta toplam dane kayıpları ilerleme hızı ve ürün neminin artmasıyla azalmıstır. Yolucu baslıkla hasatta toplam dane kaybı değerleri ilerleme hızına bağlı olarak %11 nem içeriğinde %1.11 ile %0.86 arasında değisirken %16 nem içeriğinde %0.82-%0.59 arasında değismistir. Yakıt tüketim değerleri ise ilerleme hızının artısı ile azalmıs ancak dane neminin yükselmesiyle artmıstır. Bu değerler yine ilerleme hızına bağlı olarak yüksek nem içeriğinde 6.4-8.0 l $ha^ {-1}$ arasında kalırken, düsük nem içeriğinde 7.6-8.8 l ha-1 arasında değismistir. Klasik baslıkla ideal hasat hızı (5 km $h^ {-1}$) ile yolucu baslığın en yüksek hasat hızı (9 km $h^ {-1}$) karsılastırıldığında yolucu baslıkla hasatta toplam kayıpların aynı kaldığı, gerçek tarla kapasitesinin %153 arttığı ve yakıt tüketiminin ortalama %32 azaldığı belirlenmistir.
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, 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 $h^ {-1}$) 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 $h^ {-1}$ forward speed, total grain looses and fuel consumption were 0.79%, 10.4 l $ha^ {-1}$ and 0.71%, 12.2 l $ha^ {-1}$ 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 $ha^ {-1}$ for high moisture content and varied from 7.6 to 8.8 l $ha^ {-1}$ for low moisture content. Comparing the conventional header at ideal forward speed (5 km $h^ {-1}$) with the stripping header at highest forward speed (9 km $h^ {-1}$), 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.
