- Abstract
The aim of this research is to evaluate three types (pulsed motion double head, hook type, and pneumatic comb) of commonly used hand-held olive harvesters for small scale olive orchards. The evaluation criteria were harvester productivity (Pr), fruit removal percentage (FR), fruit damage (FD), specific consumed energy (SCE), and olive harvesting cost (HC). Overall evaluation criterion (OEC) was developed depending upon the relative weight of each evaluation criterion. Relative weights were arranged according to the importance of each evaluation criterion. The results showed that the highest value of the overall evaluation criterion was 84.9% for the T3P1500 treatment (pulsed motion double head olive harvester at speed of 1500 rpm). Through this condition, the values of evaluating criteria were 88.4 kg h-1, 98%, 6.6%, 17.0 W h kg-1, and 0.041 $ kg-1 for Pr, FR, FD, SCE and HC respectively. In addition, the values of OEC of the pulsed motion double head olive harvester for the other treatments (T1P1100 and T2P1300) outperformed the other harvesters at all treatments.
