The head for thinning work with grapple function
The tiltable feeding unit is the unique feature of the KONRAD-harvester heads and completes the family in the first thinning segment. If mounted on a compact excavator or KONRAD thinning harvester – WH40-1 always has proven its quality.
The feed rollers of the 2-wheel drive always work in optimum position and maximize traction thanks to adaptive parallel bar. The automatic knife pressure reduction in relation to diameter and tree species as well as the delimbing knives geometry maintain an excellent delimbing result. The sophisticated hydraulic system of WH40-1 is located almost entirely in the frame unit for easy access for maintenance work. Sensors always work precisely and deliver correct measurements to control system KTC.
