The work compares the time consumption, productivity and prediction models of skidders performing the skidding in the territory University Forestry Enterprise of the Technical University in Zvolen. Based on the method of skidding, we divided the wheeled skidders into two groups namely: cable and cable-grapple skidder. The main aim of the study was to objectify the skidder time consumption and establish the impact of production factors on the time consumption of partial work operations of skidders. Measuring the time consumption of skidders was carried out using the methods of continual time study i.e. by connecting the work day snapshot with the fluent chronometry. Within the time study 231 work cycles were measured, and 53 snapshots of work day. Prediction models of partial work operations and total work cycle time were created using Generalized Linear Models. In the work were compared to calculate standardized times for individual work operations (winching, skidding and works in the landing) with the performance standards of the Ministry of Agriculture and Rural Development of the Slovak Republic through non-parametric tests Kruscal-Walis and Wilcoxon test. Non-operation times of the skidder operators’ shifts represent 24.6 % with the highest part taken by the technical operation of the work place. The result of the work points out significant differences of time consumption of particular work operations in case of the cable skidders use compared with the cable-grapple skidders. The overall time consumption of the work cycle and gross production rate of the monitored cable and cable-grapple skidders is affected by the following production factors: the skidding distance, volume of skidded logs and number of skidded logs. The impact of individual production factors on the overall time consumption of the work cycle is different for each group of skidders. The mean gross production rate of the monitored skidders varied from 33.3 to 6.91 m3.h-1 depending on the type of the skidder and type of forest stand
