Study Of Evaluating The Performance And Productivity Of A Potato Digger

Abstract

A field experiment was conducted in one of the fields of the Technical Institute in Shatrah in 2022 to study the evaluation performance and productivity of the locally modified chain carrier potato. Slippage percentage, fuel consumption and machine productivity were studied in this research. The included use of three factors: the forward speed of the tractor at three levels, where it was (2.50,3.20 and 4.00 km / h) respectively, and the second factor was the speed of the chain conveyor at two levels, 43 and 38 m /min, and the third factor is a type of chain conveyor with two levels of iron bars and cloth -coated bars. A complete random design with three replications was used in the research. The results were statistically analyzed, and the averages were tested in a way with the least significant difference at the probability level of 0.05. The results showed that the tractor speed of 2.50 km/hr, recording the lowest slippage percentage, reached 4.20%, while the speed of 4.00 km/hr had the lowest fuel consumption and the highest productivity digger. Keywords: Slippage percentage, fuel consumption, speed chain conveyor type.
