Mid-twentieth century saw an active development of mechanization aiming to improve the level of productivity in forestry. This process has been going on to the present day, affecting greater numbers of mechanized technological processes. Previously, only labour-intensive operations, such as hauling and rolling, were mechanized, while today even electric pruning shears have been serialized. The paper dwells on small-scale mechanization of thinning in parks and focuses, in particular, on the mini-skidder for removing waste after thinning. In order to determine the optimal characteristics of skidder chassis, we carried out experimental thinning in an overgrown park zone with the area of 0.3 ha. As a result, we obtained data on specific fuel consumption for a skidder driving on a logway with discrete obstacles such as tree stumps, roots and stones. Timing of all major operations was done; forest inventory measurements for the stand were performed. The results of thinning in the park area are as follows: the total volume of timber harvested is 4.9 solid m3, including 3.4 solid m3 of firewood. Specific fuel consumption per 1 m3 of harvested and removed timber is 1.48 kg/m3, labour constant 5.33 people per h/m3, including 1.5 people per h/m3 for timber hauling. The tests in situ for 2K2 mini-tractor with articulated trailer showed the possibility of using it to remove waste from thinning in recreational parks. In areas with soil having low bearing capacity, one needs to take extra steps to improve trafficability of tractors, e.g. by choosing appropriate type and size of tires, using snow chains and installing additional bearing axle on the trailer. For a more rational use of trailer’s carrying capacity, its sides can be enlarged to minimize fuel consumption. The data collected can help optimize the driver.
