New for 2022

Introducing the Precision Disk 550 Series Air Drill

With greater tank capacity and a row unit that’s designed for accuracy in tough conditions, the Precision Disk™ 550 series air drill offers greater versatility to help you boost yield potential in a range of conditions — including no-till fields.

  • Seed Placement Accuracy

    • A new closing system with indexable closing wheel angle adjustments helps growers achieve optimal seed trench closing, even in tough conditions.
    • Exclusive variable down pressure spring consistently holds the row unit at the correct depth.
    • Parallel-link design generates consistent coulter depth and seed placement; and closing wheel pressure ensures seed placement accuracy for improved stand establishment.

  • Tank Enhancements

    • The Precision Disk 550T features updated tanks with up to 140 bushels of capacity to provide the capacity you need to maximize tendering and seeding productivity.
    • Easy-to-use enhanced auto-calibration check software verifies calibration settings using scale feedback and ensures accuracy to give operators the best return on their investment.
    • Exclusive in-tank camera helps operators keep tabs on tank fill while rear-view camera helps ensure safety with maximum visibility.
    • Low-profile, rail-guided tank lid ensures effective seal and allows for easy access.

  • Versatility for Your Needs

    • A range of gauge wheel widths and options, including an open-spoke design, accommodate various field conditions.
    • Closing system comes standard with indexable angle settings, so you can set for effective seed trench closing.
    • Down pressure is adjustable from the cab with the press of a button.


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 550 series air drills are agronomically designed with a parallel-link row unit to promote earlier, more rapid emergence than competitive air drills.

Precision Disk 550 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 keep you within budget. The single-rank Precision Disk 550T 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.


    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. With the Precision Disk 500 double shoot (DS) air drill, you can add to those benefits saving time by seeding and fertilizing simultaneously. The Precision Disk 550 series air drill makes further advances to the parallel-link row unit design, offering greater seed placement accuracy than ever before.

    • 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

      • Achieves 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 inches of upward travel and 11.5 inches of downward travel

    • Tool-free Depth Adjustment

      • Adjust row unit depth with a single, spring-loaded T-handle. On the 550 and 550T, adjustments range from zero to 3½ inches; on the 500DS, from ½ inch to 2 inches.
      • The Precision Disk 550 series air drill allows for quick and easy changes to depth settings and closing wheel pressure.

    • Closing System

      • The 550 series air drill closing system comes standard with indexable angle settings, allowing operators to set for effective seed trench closing, no matter the conditions — from conventional to no-till.
      • 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.

    • Down Pressure Spring

      • 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.

    • Disk Blades

      • 18-inch Earth Metal® blades are built to withstand high-impact conditions
      • Cuts cleanly through heavy crop residue
      • Reduces hair pinning
      • Maximizes seed-to-soil contact

        • 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
