MAV Straw Choppers: A fine 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 to also spread the straw.
Our straw chopper's cutting zone has 4 rows of long life blades mounted in pairs on the rotor. For optimum cutting performance, a high density counterknife (tight spaced knife bar) is recommended.
MAV Straw Chopper Features
- Straight sharpened reversible blades finely cut straw into uniform sizes
- Paddle blades increase chopper air flow, spread width and uniformity in wide body choppers
- Fan blades generate maximum air velocities of up to 90 mph
Uniform Spreading From 20 to 45 Feet
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 uniformly spreads crop residue up to 45 feet.
The MAV generates extra-high velocity air speeds up to 90 mph to blow the finely cut straw and chaff uniformly across the cutterbar width for unmatched spreading performance.
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.
MAV Plus+ Option
The MAV Plus+ Option for Redekop complete choppers provides the extra spread needed when using 40+ft headers. All MAV Plus+ rotors run larger 50mm bearings on a forged end rotor which gives all MAV Plus+ choppers extra durability & longevity. MAV Plus+ rotors are fitted with larger tight tolerance fan blades which increase the air velocity up to 150mph and the use of specially scooped tailboard fins to spread the straw the extra distance.
