ASSISMENT PERFORMANCE OF TWO TYPES OF ASSISSTANCE PARTS (LANDSIDES) LOCALLY MADE AND TRADITIONAL FOR MOLDBOARD PLOW UNDER EFFECT DEEP TILLAGE IN SOME INDECATORS MECHANICAL PERFPRMANCE

Abstract

This study was conducted to compare two types of assisstance parts (landsides) locally made on performance moldboard plow for two levels of deep tillage. Then their effectsin power requirements criteria (drawbar power, soil resistance force to cut and consistency, energy utilization efficiency) and field performance criteria (vertical deviation percentage, and horizontal deviation percentage). Results showed that the increase deep tillage from 10-15cm to 20-30cm gave higher values for each drawbar power, soil resistance force to cut and consistency and horizontal deviation percentage. Manufactured landsides gaves higher values for energy utilization efficiency while traditional landsides gave higher values for drawbar power, soil resistance force to cut and consistency. The interaction between 20-30 cm depth of tillage and traditional landsides gaves higher values for drawbar power, soil resistance force to cut and consistency.
