This study aims to reduce the growth of weeds among orchard trees using an orchard tree waste chipping machine after developing it under three levels of cutting length ratio (≤3 cm - 3 to 5 cm - ≥5 cm), four levels of cutting diameter ratio (≤1 cm - 1 to 3 cm - 3 to 5 cm - ≥5 cm), four levels of distribution efficiency and four levels of cutting efficiency. The study was conducted at forward speed (1.8 km/h), moisture content (40%), number of knives 32, and rotation speed 2600 rpm for the cylindrical chipper. The evaluation was conducted regarding the effect of distribution efficiency, cutting efficiency (%), and cutting length ratios (%). The results can be summarized as follows: Increasing distribution efficiency from 75 to 95% and cutting efficiency from 85 to 95% led to a decrease in the amount of weeds, and increasing the percentage of cutting length and cutting diameters led to an increase in the amount of weeds at a moisture content of 40.0% (gram weight) and the number of cutting knives 32.
