Rake and collect in one operation
The Stonebear rakes are designed to follow the contours of uneven fields thanks to the adjustable depth control wheels. The reverse rotating rakes and the heavy duty spikes, made of high tensile steel in a spiral arrangement, draw the stones to the center of the machine onto the sieve. The heavy duty vibrant Kongskilde tines, engage the drum sieve and throw stones into the hopper. Soil and smaller stones are effectively separated through the sieve.

The Kongskilde Stonebear is a solid structure of high quality material, designed for a long working life with features like the power transmission which consists of V-belts to protect against overload and absorb shock forces when the drum or rakes engage a large stone. Or the heavy duty vibrant Kongskilde tines, made of convex steel, with a specially developed shape for optimal strength.
