The smallest KESLA harvester cranes are suitable for light thinning harvesters and heavy-duty farm tractors. The lateral tilt and excellent working geometry of the boom enable efficient operation in dense thinning stands. The KESLA 671H can be used with the KESLA 16RH, 18RH and 20SH harvester heads. The 685H model with a telescopic boom is compatible with lightweight bioenergy heads.
