Reinforced disc construction – robust 940 mm diameter disc, designed for heavy-duty operation without placing excessive load on the tractor engine.
4 cutting blades + 1 counter-blade – made of hardened tool steel, double-edged, ensuring a clean and efficient cut. New-generation hydraulic system – two hydraulically driven feed rollers ensure rapid and uniform material intake; features 10-level feed speed adjustment and a reverse function for retracting branches.
Independent hydraulic system – features its own pump and oil reservoir, eliminating the need for external hydraulic connections.
Paddle and breaker system – located on the rear of the disc, it enhances shredding performance and effectively ejects wood chips through a 290° rotating discharge chute.
PTO drive – torque is transmitted via a PTO shaft equipped with a shear bolt to protect the system against overload.
Three-point hitch – ensures a stable and secure connection to the tractor.
Maintenance-free bearings – shielded against dust and debris, with easy access for lubrication.
