| Abstract | ||||
| The study was conducted through season of 2020/2021to evaluate a fabricated local pneumatic cotton picker for harvesting cotton variety (Giza-94). The performance of machine was tested under different operational conditions included picking period times, cotton moister content and air suction speed. The performance of the fabricated machine was evaluated taking into account the following indicators: purity percentage, machine field capacity, power required, energy consumed and operational cost. Experimental results showed that the optimum operating parameters for cotton picking using pneumatic cotton picker were: suction hole diameter of 25 mm, cotton moisture content of 10 % and air suction speed of 50 m/s, which recorded maximum machine field capacity, acceptable purity degree, minimum both energy required and operational cost of 0.072 fed/day, 79.4%, 6.4 kW.day/fed and 3108 L.E/fed.day, respectively; compared with manual picking which recorded 6250 L.E/fed.day | ||||
