In Europe, there are potentially large amounts of pruned biomass from orchards that could be used for energy production. One of the main barriers is a lack of complete technologies for mechanisation of the harvesting of these products. Under the EuroPruning project, a new baler adaptable to different site conditions was designed and constructed. The article presents the results of performance testing of the newly developed baling machine, conducted during the harvesting of pruning residues in apple orchards. The aim was to determine the potential yield of branches per unit area of orchard, harvesting losses, and the machine’s efficiency, including its capacity and fuel consumption in two different operating configurations (with and without windrowers). It was shown that the average area rate was 1 ha/h, with a yield potential in the range 2.89-3.31 t·ha-1 and fuel consumption of 4.5-5.1 dm3·h-1. Average harvesting losses measured in the studied orchards amounted to 22% with the machine working with activated windrowers and 37% without the use of windrowers.
