Effect of various tractor speeds on potato digger performance

Abstract

A field experiment was conducted in one of the fields of the Technical Institute in Shatrah in 2022 to study the effect of different tractor speeds, conveyor chain speeds and their type on some performance indicators of a potato digger. Severely scratched tubers and slightly marked tubers and quantitative loss were studied in this research. The hand involved three levels of tractor forward speeds (2.5, 3.20,4.0 km / h), two groups of conveyor chain speeds (43, 49) m/ min and two levels of the type of chain conveyor of iron bars and rubber-coated. The complete random design with three replications was used in the research. The results showed that the tractor speed of 2.5 km/h gets the severely scratched tubers, which amounted to 3.03%, and the slightly scratched amounted to 12.37%, and the lowest quantitative loss was 1.16%. The speed of the chain conveyor, 43 m/min, get the lowest percentage of severely scratched tubers, which amounted to 4.53% and was slightly irritated. It was 14.10%, and the speed of the chain conveyor was 49 m/min. The lowest quantitative loss was 2.09%, and the rubber rods had the lowest percentage of severely scratched tubers, slight marked and quantitative loss. Keyword: qualitative loss, severely scratched, slightly scratched.
