Rake and collect in one operation
Utilizing adjustable depth control wheels, the Stonebear rakes are designed to follow the contours of uneven fields, enabling stone picking after germination. 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 stones are sieved by tines on a rotor over the exchangeable sieve after which tines lift the stones into the hopper.
When the storage hopper is full, a unique hydraulic dumping system and the approximate dumping height of 10' (3m) allows easy discharge directly into a dump trailer, truck or pile. With the high-dumping feature, stones can be dropped straight into a truck.
Theoretically, the Stonebear 2.60 has a capacity of up to 5 acres (2 ha) per hour at a 3.7 mph (6 km/h) speed. A decisive factor for productivity is the capacity of the hopper. The volume of 3 cu. yard (2.4 m3) and the load of up to 5 tons of stones, offers the best load capacity in the market.
Removes stones up to 20" (50 cm)
Thanks to heavy-duty design of lifting rotor and screen, stones from 1" (3 cm) up to 20" (50 cm) in diameter can be picked up. The lifting rotor of Stonebear 2.60 is equipped with the well-known and strong Kongskilde VTH tines that increase durability of wear parts and reduce operating costs. Further, the new sieve design allows the stones to roll into the tank for maximum cleaning effect.
