Conditioner Action

  • A combination of the wide rolls (129”) which promotes a thin material mat and the roll profile (crush type) is ideally suited to such crops as alfalfa, alfalfa/grass mix
  • Also effective for finer stemmed plants which usually have more solid stems like native hay, timothy and bermuda grass

Steel Inter-Meshing Conditioning Roller Option Steel Inter-Meshing Conditioning Roller Option

Conditioner Action

  • A crimp style is especially effective for stiff or solid plant stem material
  • Produces well-formed windrows over a wide range of widths


  • For high volume crops where aggressive feeding through header is an advantage, such as milo, sudan grass, and oats
  • In smooth stemmed crops like timothy, the steel bars provide positive crop flow from cutterbar to the windrow
  • For alfalfa producers, the steel inter-meshing roll action assists plant dry down by creating uniform crimps on the plant stem, without bruising the delicate leaves
  • Able to provide consistent conditioning through uneven crop volumes
  • In areas where crops and or conditions are considered to be abrasive
  • Extremely durable requires minimal maintenance

Finger Conditioning Roller Option Finger Conditioning Roller Option

Conditioner Action

  • Wipes stem wax from plant stems


  • Crops and conditions where removal of stem waxes combined with fluffier windrows are able to achieve desired dry down times such as Coastal Grass and other mixed forages
  • Requires the least amount of horsepower of the conditioner types
