In this article the felling, primary conversion, and transportation of wood assortments of pedunculate oak are treated. Until the end ofthe 19. centure, the main assortment of the pedunculate oak were cask staves. First sawmills were established about 1860. Separately are treated thinning andmature stands. In mature stands logging debris amounts around 20% (only bark 1 3%). In converted wood volume, cordwood participates 18% and merchantable timber 82%. In merchantable timber, logs participate 92% (veneer logs 16%), mine props 7% and conducting wire poles 1%. Felling and primary conversion work is performed with power saws. In thinning, conversion of long length logs is prefered.By primary transportation wheeled and crawler tractors are used, with tree len gth, semi-tree length-, and long length log-systems. By assortment are mostly with mounted winches. Now, the wood over 7 cm diameter o.b. is converted. By chipping is would be possible to exploit thinner wood too.
