PrimeLine straw chopper knives

The PrimeLine straw chopper knives by GROUP SCHUMACHER combine extreme wear resistance with a self-sharpening effect for consistently precise cutting performance. The tungsten carbide coating, applied by laser cladding technology, embeds ultra-hard particles into the blade surface – dramatically extending service life compared to standard blades. As the carrier material wears back faster than the coating, a permanently sharp cutting edge forms automatically. Less energy consumption, lower fuel costs, optimum straw distribution and faster decomposition. GROUP SCHUMACHER – Perfect Harvest.
