Row Unit


Case IH engineering worked tirelessly through the Customer Driven Product Definition (CDPD) process to bring an all new row unit to the marketplace. The new row unit cuts residue, opens a high quality, uniform seed trench, delivers the seed perfectly, and closes the trench better than any row unit in the market place. And even with all those features, it requires less maintenance and utilizes less power to pull than prior designs and competitive units. This makes the producer more efficient, improves yield potential and makes them more productive.



  • Consists of an upper and lower arm that extends rearward and attaches to the sturdy cast row unit frame.
  • The cast lower link carries the weight of the 165 pound row unit
  • The upper link allows the row unit to lift and lower level
    • Ensures even seed depth placement in any soil condition
  • Provides the potential for faster ground speed and more acres seeded per day
    • Allows 8.5 in. of upward travel and 11.5 in. of downward travel for maximum ground following capability
  • The parallel link bushings feature oil impregnated copper iron alloy bushings
    • Don’t require grease, reducing maintenance and increasing uptime


  • Each of the ranks across the drill utilizes a cylinder to lift and lower the rank
    • Rank down pressure is also sustained by this cylinder
  • The number of row units on each rank are matched to cylinder size to minimize the differential pressure between ranks
  • The down pressure across the full width can be adjusted via
    • Mechanical knob adjustment on the down pressure manifold
      • Features a mechanical gauge positioned on the toolbar to allow the operator to easily view the current down pressure
    • In-cab adjustment on the AFS Pro 700 (or ISOBUS)
      • Features an electronic display
  • Available down pressure range is between
    • 200-1300 psi (30 ft.)
    • 200-1450 psi (40 ft.)


  • Additional weights can be added to the tool bar if needed for hard ground conditions and deep seeding depths
    • Could be needed in soil conditions that are no-till and/or clay based soils
  • Tilled ground typically doesn’t require any additional weights
  • Optional weight brackets are available for easily adding additional weights to both wings and center section
    • No more than 1400 lbs should be added to the center section
    • No more than 600 lbs on each wing
  • 100 lb (45 kg) suitcase weights are available from the CNH parts organization (part #: 86988727)


  • Responsible for carrying and providing the down pressure for the two unit ranks
  • The majority of the sub-frame and rockshaft is welded together for additional strength
  • Makes the frame more robust and provides superior durability over bolted joints


  • Made from boron earth metal steel and measures 18 inches in diameter and is 0.197 in.
    • When the coulter’s outer diameter reaches 16 in. it should be replaced
  • The coulter is positioned at a 7 degree angle to open a high quality seed trench
  • The opener hub utilizes a heavy duty, double row, triple lip sealed bearing
    • No bearing maintenance is required
  • The single bevel opener is ideal for cutting residue because the angle of entrance is close to 45 degrees, even at shallow depths
    • Allows the opener to slice and cut through residue to reduce hair pinning that can reduce soil-to-seed contact, germination and ultimately overall yield


  • Critical to keeping the opener disk clean is the scraper with tungsten carbide wear components
  • Extends further down the opener to protect the seed as it is dropped into the seed trench
    • Provides proper seed placement for high yield potential
  • The spring loaded scraper fits behind the profile of the angled opener which prevents it from dragging in the soil and seed trench
    • Provides lower overall draft of the entire disk drill and lower down pressure requirements


  • Help guide the seed towards the seed trench after metering
  • Features a unique tube with a forward facing design
  • Directs the seed toward the scraper which stops the seed and allows the seed to fall vertically in the seed trench and reduces seed tumble once it reaches the trench
  • To overcome the seed tumbling or prevent the seed from exiting the seed trench prior to closing, often a seed-loc wheel is used on competitive openers
    • In some soil conditions the seed-loc wheel can actually pull seed out of the trench
  • The Precision Disk Drill row unit doesn’t require a seed-loc wheel due to the design of the scraper, seed tube and closing wheel
  • A deflector is located behind the scraper and seed tube to help contain any seed that might attempt to bounce out of the seed trench


  • A single, spring loaded T-handle allows simple adjustment of row unit depth at each opener
    • No tools are required for adjustment
  • As the T-handle is adjusted fore and aft, the gauge wheel rotates up or down to adjust seeding depth for an individual row unit
    • The row unit and the T-handle are made of cast iron
  • True 0-3.5 in. depths are available in 14 different increments
    • Every other notch is identified on the case frame to help the operator apply the same depth across the tool and easily return to that preferred depth
  • The only greaseable point on the row unit is found on the gauge wheel adjustment spindle
    • Requires greasing every 50 hrs. or once per season
  • The tolerance between the handle tab and the notched row unit frame is tight to help retain the handle in place and provide worry free depth control


  • A single, spring loaded T-handle allows simple adjustment of row unit depth at each opener
    • No tools are required for adjustment
  • As the T-handle is adjusted fore and aft, the gauge wheel rotates up or down to adjust seeding depth for an individual row unit
    • The row unit and the T-handle are made of cast iron
  • True 0-3.5 in. depths are available in 14 different increments
    • Every other notch is identified on the case frame to help the operator apply the same depth across the tool and easily return to that preferred depth
  • The only greaseable point on the row unit is found on the gauge wheel adjustment spindle
    • Requires greasing every 50 hrs. or once per season
  • The tolerance between the handle tab and the notched row unit frame is tight to help retain the handle in place and provide worry free depth control


  • The four-inch wide, double-edged closing wheel is designed specifically for closing in any condition
    • Sand, loam or clay
    • Even in soft ground, the closing wheel is able to float and close the seed trench
  • This extremely durable wheel is tilted slightly to one direction
    • One raised edge of the wheel breaks the side wall
    • The opposing edge captures the soil, preventing it from moving outside of the trench area


  • There are three different down pressure settings to meet the field conditions
    • 59 lbs.
    • 71 lbs.
    • 84 lbs.
  • Adjustment of the pressure is easily done by moving the single handle to a different notch




The new Precision Disk 500 Air Drill sets new standards in productivity and agronomics in broad acre seeding because of the new row unit and frame design. The Precision Disk 500 utilizes an external seed supply air cart. Depending on your configuration this can be a tow between or tow behind air cart.
