MAV Straw Choppers offer finer straw cut for better seeding performance. The development of Redekop's Maximum Air Velocity (MAV) Straw Chopper is a breakthrough in crop residue management. The MAV's revolutionary design uses two zones for cutting and spreading, rather than a traditional rotor design that depends on the cutting blades or spinners to also spread the straw. Redekop’s straw chopper's cutting zone has up to 8 rows of long life blades mounted in pairs on the rotor.
Uniform distribution of straw and chaff across the width of the cutterbar is critical for seeding – especially for reduced till or no-till systems. Poor residue management can lead to:
Retrofit kits are available for most major models of combines in Europe.
Redekop serrated blades self sharpen and will noticeably increase the chop quality therefore producing straw that is finely cut into uniform sizes. Benefit to the farmer: smaller straw particules will decay faster into organic matter and thus not disturb the next crop.
The MAV residue manager allows you to easily fine-tune the spread to match changing field conditions. In the field, the easily adjustable fins and tailboard fine-tune the spread for uniform residue distribution across the width of the cutterbar. Complete replacement choppers feature independent left and right rapid adjustment with Redekop's exclusive split tailboard design.
The airflow-generating zone uses Redekop's patented fan blades tucked away outside of the cutting zone. Specially designed shrouds build up air speed around the six fan blades at either end of the rotor. The MAV generates extra-high velocity air speeds up to 90 mph / 145 kph to blow the finely cut straw and chaff uniformly across the cutterbar width for unmatched spreading performance.
