The Kesla roller harvester models Kesla 20RH and Kesla 20RHS are fast, maneuverable roller harvester heads for thinning and final felling of weak timber stands in which the trees have an average trunk diameter of less than 30 cm. The gripper opens a maximum of 45 cm.
These lightweight but sturdily built roller harvester heads have an exceptionally high feed and cutting capacity for their size class.
Four delimbing knives do a good job and make it easier to back the logs. Accessories available include ProCon and HydCon, color marking, automatic chain adjustment and stick handling. Felling machines with a wheeled chassis and an operating weight of 8-13 tons are recommended as carrier vehicles for the Kesla 20RH and Kesla 20RHS models.
