Performance of locally manufactured chisel plow weapons in different working conditions

: included determining the dimensions and measurements required for the manufacture of excavator weapons, determining the appropriate type of metal, and manufacturing the plow weapons according to the dimensions and measurements.The field evaluation of competence took place. Manufacture of locally manufactured excavator plow weapons and compare them with traditional plow weapons and study some field performance indicators by conducting a practical experiment in which the following factors were adopted: The first factor is the use of the forward speed of the plow at the two levels (3.56 and 5.11) km/h, and the second factor is the use of the type of metal. For excavator plow weapons. On two levels (traditional plow weapons and locally manufactured plow weapons). And a study of the extent of the influence of these factors on the studied characteristics, which included: tillage appearance (the number of dirt blocks with a diameter of more than 5 cm/m2), the work width utilization factor, and performance efficiency.. A randomized complete block design (RCBD) with a split-plate system and three replications was used. The following are the most important results : The front plowing speed was (3.56) km/h significantly superior in giving higher values for the plowing appearance, while the front speed was (5.11) km/h and was significantly superior in giving higher values for each of the parameters. Exploitation. Job offer and performance efficiency. As for the plow, the manufactured plow weapons were significantly superior in recording higher values for both the labor supply utilization factor and performance efficiency, while the traditional plow weapons were significantly superior in recording higher values for the plow appearance. The bilateral interaction between the forward speed of plowing and the type of plow weapons was superior. Locally manufactured excavator plow weapons with a forward speed of (5.11) km/h give significantly higher performance efficiency values.
