Together with the growth of young trees cultivation carried out by the National Forestry Board it became necessary to mechanize the works that would increase their efficiency with equally high quality. Recognition and optimalization of worktime structure of brush cutter operators during cultivation is of great practical importance in this context. Technological improvement of cultivation in the analysed experiment applied a square method (fig. 1), while technical rationalisation consisted in cutting around young trees. The worktime structure of the described workstand was defined with the help of a working day photography being taken for three days for four workers. Next the measured time data were classified according to a scheme from fig. l. A relatively high fraction of resting time and maintenance of the brush cutter in a workshift proved that an exploitation shift time coefficient of effectiveness was 0.61. On the basis of differences between effective worktime and rest distributions as well as technological stand-still and everyday maintenance it was presumed that the cause of frequent work breaks were repeated repairs of brush cutters.(fig. 6). High value of coefficient of operating time efficiency (0.93) proved the optimum choice of the applied technology. The work efficiency assumed for the experiment - three times higher than for a hand tool -indicates that it is necessary to turn to a hand-machine level of cultivating.
