pull-type

TerrainPro Row Unit

  • 20” lead coulter features 1,500 lbs. of down pressure and 6-bolt greaseable hub with 5 layers of seal protection for long-term, trouble-free use.
  • Free-floating row cleaners follow ground contours independently from the lead coulter and clear residue from the strip. The curved finger design prevents trash from wrapping and width adjustment allows the operator to adapt the row cleaner to varying conditions.
    • Row cleaners feature 4-bolt hubs with triple-lip seals and tapered roller bearings.
    • Standard add-on weights allow the operator to increase down pressure if needed.
  • Independent row unit depth is maintained by the crowfoot depth control wheel that runs between the row cleaners and the shank for consistent shank depth from row to row.
    • The 16” diameter crowfoot design prevents mud, rocks and other debris from building up, allowing the operator to run in varying conditions.
    • Each row unit features independent parallel linkage which allows it to free-float 7” upward and 4” downward to follow uneven terrain which ensures that each shank runs at the same depth for consistent tillage and fertilizer placement.
    • Optional rock guard crowfoot depth control wheel with reinforcing rings adds strength in rocky soil.
    • Optional rubber depth control wheels with scrapers are available for extremely rocky and tacky soil conditions.
  • The shank features tool-free height adjustment from 6” to 12” deep and a convenient depth gauge allows the operator to quickly and easily adjust each shank.
    • Available with spring-cushioned auto-reset trip mechanism with 2,000 lbs. of point load pressure or shear-bolt protected shank with 5,000 lbs. of shear pressure.
    • Replaceable 2 ¼” cast point and 1 ½” wide integrated wear bar provides long-term, trouble-free use.
    • Replaceable shank wear plates are standard to protect the shank from abrasive soil.
  • 18” notched concave closing coulters on each side of the shank keeps the soil in the path of the trailing basket. Each coulter floats independently from the other to keep constant ground contact through uneven terrain.
    • Tool-free width and angle adjustment allows the operator to easily change the width of the strip and height of the berm.
    • Each closing coulter features tool-free adjustable spring down pressure and angle adjustment to control the amount of soil being sent into the berm.
    • Closing coulters utilize 6-bolt hubs with triple-lip seals for long-term, trouble-free use.
  • The trailing 14” diameter crowfoot conditioning baskets break up clods, condition the berm and feature a unique design to prevent plugging with mud, rocks or other debris.
    • Each crowfoot conditioning basket rolls independently from the other and features tool-free adjustable down pressure.

Fertilizer Systems

  • Dry or liquid fertilizer application systems are available for pull-type models of the Raptor strip tillage tool and the tanks are located behind the toolbar for better row unit visibility from the tractor cab and easier filling from behind the machine.
  • Both systems feature a standard Raven RCM ISOBUS controller which allows the operator to control the rate from the tractor's virtual terminal screen.
    • This system integrates with section control and pre-loaded field prescriptions.
  • 380/90 x 46 dual wheels and tires maximize flotation and provide a stable ride during road transport.

Nitrogen Fertilizer & Application

  • Dry/Granular by Broadcasting – Urea contains 46% nitrogen
  • Gas/Vapor by Banding - Anhydrous Ammonia contains 82% nitrogen
  • Liquid by Injection – UAN Solutions contain 28% or 32% nitrogen

Ways We Lose Nitrogen

  • Denitrification – temperature, moisture and pH play a major roll.  If the soil is cold and saturated, active soil organisms take oxygen from the nitrate molecule, which converts it to Nitrous Oxide, Di-nitrous Oxide or pure nitrogen gas, becoming unusable.  These gases are released into the atmosphere, otherwise known as denitrification
    • Denitrification is most serious on soils that are poorly drained but can occur on any soil that is saturated with water
  • Volatilization or Urea Hydrolysis – a biological process that occurs when the urea molecule converts to ammonia gas and is released into the atmosphere
  • Leaching – the nitrate molecule is not held by the soil and will be carried by water.  This movement of nitrogen through the soil can deliver nitrates below the roots into the subsoil, otherwise known as leaching
    • Leaching is most serious on well-drained, sandy and gravelly soils but also can occur on well-drained upland limestone and shale soils

Ways We Can Minimize Loss

  • Delaying part of the nitrogen application until corn is 10 to 16 inches tall (sidedressing) can minimize leaching and denitrification when corn needs it the most
    • Corn needs nitrogen at each stage of development, however, the most nitrogen is required prior to the grain fill period
  • Incorporating fertilizers that contain urea into the soil within 24 hours can minimize volatilization

Example

  • Approximately 1 pound of nitrogen yields 1 bushel of corn
    • If the goal is 200 bushels of corn per acre, then 200 pounds of nitrogen per acre is needed
    • Ideally, 50 pounds applied at planting and 150 pounds at sidedressing (when the plant is between 10 and 16 inches tall and needs it most)
