Popis: The study was conducted during the agricultural season (2017-2018) and the size distribution of soil particles was (10.5% sand, 51.7 clay, 38.25 silt) so soil texture is clay soil to find out the effect of adding weights on the wheels of the agricultural tractor using the moldboard plow by measuring some indicators, including the drawbar power, soil resistance penetration, tillage depth achieved, and the soil disturbed volume and the field was divided according to a split plot arrangement under Randomized Complete Block Design with three replications. The results of the study showed that the addition of weights on the wheels of the tractor (310) kg recorded the lowest value for drawbar power and highest value for the tillage depth achieved, and the soil disturbed volume, while not adding weights (0) recorded the lowest value for the soil resistance penetration. The forward speed (3.3) km.h-1 excelled in recording the lowest value of the drawbar power and highest value of tillage depth achieved, while the third speed (7.7) km.h-1 excelled in recording the highest value of the soil disturbed volume and the lowest value of soil resistance penetration. The interaction between adding weights on the wheels of the tractor (310) kg and the forward speed (3.3) km.h-1 registry the less value the drawbar power and the highest value for soil resistance penetration and tillage depth achieved, while the addition of weights on the wheels tractor (310) kg and the forward speed (7.7) km.h-1 registry the highest value of the soil disturbed volume.
