Comparison of Performance Characteristics of Different Types of Hazelnut Harvesting Machines

In this study, the possibilities of using the hazelnut harvesting machine with pneumatic effective harvesting unit produced by local manufacturers and the prototype manufactured hazelnut harvesting machine with mechanical effective harvesting unit in the mechanical harvesting of hazelnuts grown in flat and near flat land conditions were examined, some performance values (harvesting efficiency, labor requirement, machine+human labor requirement, field productivity, machine+human field productivity and kernel productivity) of hazelnut harvesting machines with mechanically operated harvesting units were determined under different orchard yield conditions. According to the results of the experiment, the hazelnut harvesting machine with a mechanical effective harvesting unit had a harvesting efficiency of 92.54-96.03% and; a labor requirement of 6.349-9.839 MİGh ha-1; machine+human labor requirement of 46.228-62.531 BİİGh ha-1; field productivity 0.158-0.102 ha MİGh-1; machine+human field productivity: 0.022-0.016 ha BİİGh-1; kernel productivity: 124.83-1322.08 kg h-1. The hazelnut harvesting machine with a pneumatic effective harvesting unit has a harvesting efficiency of 97.68-99.36%; labor requirement 70.349-105.647 BİİGh ha-1; machine+human labor requirement 108.509-147.481 BİİGh ha-1; field productivity 0.014-0.009 ha MİGh-1; machine+human field productivity 0.009-0.007 ha BİİGh-1; kernel productivity 18.90-67.18 kg h-1. As a result, when the characteristics of harvesting efficiency, field productivity, and kernel productivity of the machines are compared, the mass production of hazelnut harvesting machines with mechanically effective harvesting units can provide benefits for hazelnut producers in terms of reducing harvesting costs and demand for labor.
