In this study, the effects of the cotton picker model and drivers ability on cotton harvest losses and cotton quality wereinvestigated. In experiments, five cotton pickers were used. Four cotton pickers have four rowed and one picker has sixrowed with baler. John Deere cotton pickers were used in 2013 cotton harvest season. All of the experiments wereconducted on BA119 cotton variety with and without defoliant treatment in Diyarbakır city.Defoliant and boll opening chemicals (DROP Ultra + FINISH Pro) that were applied 15-25 days prior to harvest. Inconclusion, no difference was found between in cotton lint quality by hand harvest and cotton pickers. On the otherhand, cotton picker model and drivers ability were statistically differed on harvest losses. The highest harvest loss (60kg da-1) was found on 1998 model picker. The harvest losses were low than 25 kg da-1 on 2007 and the youngest modelpickers. Fiber property measurements made by High Volume Instrument (HVI) systems. It is widely used to describecotton quality in international commerce.
