According to the data of the Central Statistical Office, there has been an increase in forest cover in Poland from 27.8% to 29.6% over the last 25 years. This increase contributed to an increase in the possibility of wood obtaining and processing for energy purposes. The aim of the study was to analyse the efficiency of a chipping machine manufactured by the American Company Bandit Industries (Bandit 990XP chipper) based on the working day chronometer. The study was carried out in specific conditions related to the place of the chipper application because the machine was used to process the material obtained from standing trees in the framework of park maintenance. As it was shown during the analysed working day, the effective capacity W1 in the work cycle of the Bandit 990XP machine was 9.2 m3∙h–1 chips. Specific working conditions made it impossible to organize the work smoothly. Ongoing obtaining of the material for chipping from standing trees resulted in low productivity during the exploitation time of the shift W08 on the level of 1.3 m3∙h–1 chips.
