Precision Disk Air Drill Family

Make the Most of Your Season, Soil and Seeds
Case IH Precision Disk air drills are designed to help you work more efficiently, so you can be more productive — no matter the residue conditions you’re dealing with or crops you plant. Precision Disk air drills are a versatile seeding tool to help you seed a broad range of crops more consistently and effectively.Plus, Precision Disk air drills allow you to seed at higher speeds and spend less time on daily maintenance.

High-Efficiency Seeding

Boost ROI with Earlier Soybean Emergence

Studies show that getting in the field earlier for planting is critical to maximizing soybean yield potential1 — and late-emerging soybeans can be costly, with a potential loss of up to $140/acre.2 That’s why Precision Disk 500 series air drills are agronomically designed with a parallel link row unit to promote earlier, more rapid emergence than competitive air drills.

Precision Disk 500 series air drills let you plant soybeans earlier and into tough no-till seedbeds — so you can seed with accuracy, no matter the conditions, and stay within budget. The new single-rank Precision Disk 500T air drill offers a cost-effective solution for earlier soybean seeding.

Frame & Transport

Convenience and Durability in a Rugged Frame Design
From welded-frame connections to increase durability to simple folding for transporting, Case IH Precision Disk air drills are designed to add reliability and ease of use to exceptional performance.
    Main Frame
    • Main Frame
    • Wing Frames
    • Transport
    Main Carrying Frame
    Utilizes 6" x 10" x 3.8" (15 cm x 25 cm x 9.5 cm) wall tubes to support the row unit carrying subframe.
    Center Main Frame
    Tubes are oriented in a "V" to distribute the weight of the main frame, adding additional support and stability during transport.
    Front Caster Wheels
    Travel in a different path than the rear caster wheels, providing exceptional weight distribution, reduced ground pressure for even emergence and allowing for a smaller transport envelope.
    Nearly every part of the machine is powder coated to provide a superior paint coating that is resistant to impacts and paint-fading UV rays and helps prevent corrosion.
    Three-Section Flex
    A three-section frame drill with single-fold wings provides narrow transport. When in field position, the wings can flex 15 degrees up and 10 degrees down for superior ground following.
    A single-fold cylinder is used to fold the wings, providing fewer service points and resulting in more uptime and reliability.
    Wing Pins
    Each wing pivot utilizes hardened Grade 8 wing pins with replaceable hardened bushings for long wear life.
    Vertical Fold Design
    Allows for lowest transport height in the industry as well as narrow transport widths.
    Wing Lock
    The 25- and 30-ft models also utilize a wing lock for safe transport.
    Single Remote Lever
    A single remote lever inside the tractor folds or unfolds the Precision Disk air drill.
    Wide Profile Transport Wheels
    The wide profile of the transport wheels provide the stability to move the disk drill confidently, even at higher roading speeds.

    Row Unit

    Gain Efficiencies and Improve Yield Potential

    Through our Customer Driven Product Design (CDPD) process, Case IH has engineered an agronomically designed row unit that cuts residue; opens a high-quality, uniform seed trench; delivers the seed perfectly; and closes the trench better than any row unit in the marketplace. And with the Precision Disk 500 double shoot (DS), you can add to those benefits saving time by seeding and fertilizing simultaneously.

    Watch the video to learn more about the parallel link row unit design and its agronomic advantages compared to other row units.

    • Forward-Facing Seed Tube

      • More precise seed placement from tubes that direct seed toward scraper
      • Reduces tumble and hop with a vertical drop — keeping seed in the trench
      • Doesn't require a seed-loc wheel like many competitor models
      • Equipt with a deflector to catch seeds attempting to jump out of the trench

    • Parallel Link

      • Parallel travel of the assembly thanks to an efficient and innovative design
      • Delivers consistent coulter depth, seed placement and closing wheel pressure
      • Allows level lowering and lifting to plant at optimum depth
      • Provides 8.5 in of upward travel and 11.5 in of downward travel

    • Tool-Free Depth Adjustment

      • Adjust row unit depth with a single, spring-loaded T-handle. On the 500 and 500T, adjustments range from zero to 3½ inches; on the 500DS, from ½ inch to 2 inches.
      • No tools required for adjustments
      • Adjustment range on the 500 and 500T units divided into 14 clearly labeled increments. On the 500DS, spacing between each notch is progressively larger from lowest to highest setting to compensate for the travel arc of the gauge wheel on the arm.

    • Down Pressure Spring

      • Case IH exclusive variable down pressure spring on each row unit
      • Ensures even emergence and minimized compaction across terraces and uneven terrain
      • Keeps the gauge wheel engaged with the ground for consistent depth and seed placement

    • Closing System

      • Heavy-duty, smooth-faced concave 4-inch-by-12-inch packer wheel
      • Designed specifically for closing in tough conditions — whether in clay, sandy or mixed soils
      • Seals the trench effectively with a double-edged closing wheel
      • Exclusive to the 500DS, the Precision Placement Knife™ accurately places seed and then helps close the trench. Unique steel composition with carbide edges and design allows for durability, extended wear and easy replacement.

    • Disk Blades

      • 18-inch Earth Metal® blades — a proprietary steel equipped to withstand that high-impact conditions
      • Cuts cleanly through heavy crop residue
      • Reduces hair pinning
      • Maximizes seed-to-soil contact

      Find Your Match For Easy Maneuvering

      Our Precision Disk 500 and 500DS models give you the choice of either a tow-behind or tow-between configuration, while our 500T lets you be more versatile with a mounted seed tank. Whichever model you choose, all come equipped with a strong cast Cat IV hitch clevis for secure hitching.
      • Front Hitch

        • Floating style front pull hitch
        • Allows the disk drill to float up and down, independently from the tractor and hitch
        • Improves ground following and seed depth control because the hitch will not raise or lower the front of the tool when the tractor rides over a hill or obstacle
      • Rear Hitch*

        • Hook up any tow-behind air cart with ease
        • Ensures a tight implement turning radius and follow the tracks created by the tractor during transport
        • Provides enough room to allow the drill frame to be folded into the transport position without disconnecting the air system
        • Lights and ISOBUS connectivity
