  1. W & T Operation and Adjustment Section 140 W & T Residue Management

  2. Residue Management • Flexibility • Windrow straw and spread chaff (1) • Chop straw and spread chaff (2) • Remove chaff spreader to get chaff in the swath (e.g. for biomass) (3) • Meets all customers residue requirements • Even uniform residue distribution • Even nitrogen fixation over the whole area • Prevents erosion • Better rotting • Lower disease risk for following crop • Even crop emergence • Reduces input costs for • Tillage • Fertilizer • Chemicals • “Increases following year crop yield!” 1 3 2 W & T Ops & Adj- Residue Management

  3. Residue Management • Standard straw chopper • 56 knives, 54 counter knives - 5 walker • 68 knives, 66 counter knives - 6 walker • Easy, quick changeover from chop to windrow – no tools required • Pivotable counter knives to adjust aggressiveness and quality of cut • Best in class chopping quality • Hydraulically powered chaff spreader (option) • Reliable, maintenance free drive • Spreads chaff evenly over the full cutting width • Can be easily removed if necessary W & T Ops & Adj- Residue Management

  4. Residue Management Dual speed chopper drive (optional) • Two chopper speeds, by changing over the belt: • 1800 rpm (rape ,corn) • 3600 rpm (small grains) • Fits all crops and conditions ”Gives you the flexibility you need!” Vane tailboard • Electrically adjusted from the cab (optional) • Spreads chopped straw evenly over the whole working width of the platform W & T Ops & Adj- Residue Management

  5. Chop or windrow W & T Ops & Adj- Residue Management

  6. Residue disposal All W & T - series combines can be equipped with a Standard or a Premium Chopper. W & T Ops & Adj- Residue Management

  7. Premium straw chopper • Higher number of knives. • Double number of knife rows. • Higher speed of discharging air. • Shorter chopping length. • Best straw distribution. W & T Ops & Adj- Residue Management

  8. Standard Chaff Spreader Standard Spreader W & T Ops & Adj- Residue Management

  9. Premium Chaff Spreader Premium Spreader Adjustment Premium Spreader W & T Ops & Adj- Residue Management

  10. Premium chaff spreader • Patented concept • Chaff is spread with chopped straw. • Alternatively chaff can be spread separately to the side. • Stair step chaff pan rapidly moves material to the twin spreaders W & T Ops & Adj- Residue Management

  11. Premium Chaff Spreader options 1. 2. 4. 3. W & T Ops & Adj- Residue Management

  12. Premium Chopper W & T Ops & Adj- Residue Management

  13. Reasons for premium chopper • Heavy yields and long-strawed varieties. • Better straw distribution. • Cutting platforms > 6,5 m. • Fast rotting of the straw mat due to shorter cutting length. • Ideal for minimum tillage practice. • The retention of nitrogen by soil organisms can be enhanced. • Thick straw layers mixed into the root zone stop capillary water transport and cause water stress in next season. W & T Ops & Adj- Residue Management

  14. Straw Chopper “W” and “T” Combines W & T Ops & Adj- Residue Management

  15. Tailboard deflector plates • Patented Tailboard and Deflectors: • Optional electric motor adjusted tailboard (Standard on premium chopper) can be used for side wind compensation. • New automatic side swap button in the CommandCenter. • Tailboard vanes change side automatically. Straw Straw Wind compensation:> 50 % of straw is directed to one side W & T Ops & Adj- Residue Management
