Scoops +

Coal Scoop Carry Capacity
30.0 yd³
Type
Large capacity scoops for both wood chip and coal applications. A mesh screen integrated into the back of the scoop maintains visibility to the cutting edge. The chip scoop version has extra screens at the top due to higher capacity.
Components
Both scoops come with dual lift cylinders for increased lift capacity. Integrated stabilizer system makes sure that the scoop stays stable and centralized on the machine. Scoop tilt function is standard and provides ±15 degrees of tilt to maintain grade conditions and keep your operation safe.
