REQUIREMENTS OF THE POWER AND CAPACITY OF THE LOCALLY MANUFACTURED CHISEL PLOW WITH MOVABLE WING WEAPONS

A mechanical experiment was conducted at the College of Agriculture on clay soil using a randomized complete block design (RCBD). It included three factors: three widths of the chisel plow weapon (15, 19 and 23) cm, three plowing depths (15, 20, 25) cm, and three gears. Front (S1, S2 and S3) to find out the effect of draft force, slip ratio, fuel consumption, loose soil area and field efficiency. The research aims to obtain on the best weapon for the chisel plow that can penetrate the soil with the least resistance and achieve positive results for the technical characteristics of the mechanical unit represented by the energy requirements. The upgraded chisel plow weapon, with a width of (15) cm, excelled by recording the lowest pulling force, slip percentage, and fuel consumption compared to other upgraded plow weapons and the traditional plow. The depth of plowing was (15) cm by recording the lowest pulling force, slip percentage, fuel consumption and the highest field efficiency compared to the plowing depth (20 and 25) cm. The plowing speed was superior to (S1) by recording the lowest drag force and slip percentage, while the plowing speed (S3) recorded the lowest fuel consumption and the highest field efficiency.
