In order to solve this problem, more environmentally friendly and sustainable solution methods are gaining importance by shredding the pruning residues and mixing them into the soil, thus preventing erosion, increasing the soil organic matter content, and accordingly increasing the agricultural yield. Shredding process is carried out with branch shredding/grinding machines developed for this purpose. Therefore, it is important to know the cutting properties of the residues to be shredded so that these machines can work more effectively and efficiently. For this purpose, the cutting force and energy values to be considered in the design of a machine to be used for shredding pruning residues were determined for 7 different plant species (Juniperus Drupacea, Pyracantha Coccinea, Shrub, Pine, Oleaster, Peach and Oleander), at different moisture levels and in the cutting axis, considering the diameter values. The effects of these variables were researched on cutting force, strength, energy and specific energy consumption. As a result, changing the cutting axis significantly affected the cutting force, strength, energy and specific energy consumption values in all varieties, and the values found for the horizontal axis were quite high compared to the values found for the vertical axis. When the changes in the moisture content and diameter of the samples and their effects were examined, although the moisture values of Shrub, Pine, Oleaster and Peach cultivars were reduced (respectively % 34.5, % 30.1, % 28.6, % 35.6), these moisture rates did not have a statistically significant effect on the cutting force, strength, energy and specific energy consumption. The variation of moisture content of Juniperus Drupacea, Pyracantha Coccinea and Oleander cultivars had a significant effect on the cutting parameters. These results obtained in the study can be used in the design of a machine to be developed for the effective and efficient shredding of the pruning residues of the tested varieties.
