RESIDUE MANAGEMENT

  THE IMPORTANCE OF DEALING CORRECTLY WITH CHAFF AND STRAW

  In operations where the use of straw is not the practice, CR9000 Elevation combines provide the optimum handling of straw and chaff. Conservation tillage is an arable farming technique that is growing in popularity and consists of planting after minimal or even zero land tillage. It reduces labour time and can lead to increased crop yields and reduced soil-erosion. One draw-back of this farming practice may be the pest problems created by moisture trapped in crop residues. This makes it vital to have adequate straw chopping and wide and even straw and chaff distribution, especially when working with the large headers common on CR9000 Elevation combines.

  PERFECT STRAW FOR BALING

  The in-line crop flow of the pure rotary breed CR9000 Elevation combines respects the straw. The exclusive Twin Rotor™ system eliminates the need for a drastic change of speed and direction. As a result the straw maintains its structure. The gentle crop treatment reduces straw breakage even at high outputs and produces high quality straw that is ideal for baling.

  CHOPPING FINE – SPREADING WIDE

  The increasing importance of residue management has resulted in the offering of choppers entirely developed and produced by New Holland. On CR9000 Elevation combines there is a choice between four or six rows of knives. On the choppers with six rows, knives with impeller characteristics are installed at the outer edges of the rotor for high spreading capacity. The high chopper speed of 3500rpm helps ensure the fine chopping and wide spreading of even the heaviest crops.

  FULL WIDTH SPREAD FOR OPTIMISED CULTIVATION

  The use of the 10.7m (35ft) Varifeed™ header on the CR9090 Elevation requires a dedicated and powerful straw spreading system. The optional Opti-Spread™ straw spreader mounted behind the straw chopper, easily meets any practical spreading width requirement. The two powerful rotors have full adjustment to neutralise side-wind or hillside impact. For total operator convenience and uninterrupted field work, the adjustments are fully cab controlled.
