Special efforts are taken to replace manual work by machines when it is dealt with precious stands such as Croatian pedunculate oak forests. The paper deals with morphological analysis of mulching flail mowers and with exploitation test of one assembly: mulcher Seppi m. Miniforst 150 and tractor Steyr 8090a Forst. Based on the morphological analysis of this type of silvicultural working machines, it is possible to define characteristics and rules of its construction, trends of its- evolution and evaluation. The exploitation test (torque measuring) was accelerated by the problems that had occurred in the transmission of the tractor, the coupling power take-off. Key words: mulching flail mower, mechanized of silvicultural works, silvicultural pass and trail, morphological analysis, tractor PTO torque |
