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.

NEW FOR 2019

High-efficiency Seeding Advancements

Built on Agronomic Design™ principles, Case IH Precision Disk™ air drills help you maximize the potential of every seed in a variety of crops and tillage practices. Get more done with these new high-efficiency seeding advancements from Case IH. The newest high-efficiency advancement in the series is the Precision Disk 500DS air drill, which features a one-pass, simultaneous seeding and fertilizing with a double-shoot design.

Greater Durability for Optimal Performance

  • Optional tank-mounted weigh scales for the Precision Disk 500T single disk air drills provide tank weighs via the Case IH Advanced Farming Systems AFS Pro 700 display or other compatible displays.
  • A display on the Precision Disk 500T rear tank platform delivers on-the-go weight readouts to help monitor seeding rates.
  • A grease point for the packer arm on the Precision Disk 500 and 500T row units improves movement even in the most challenging situations.
  • Larger 18-inch gauge wheels on the 500DS provide improved cleaning of the disk to prevent soil throw, and their placement further back on the row delivers better depth control while seeding and fertilizing..

Technology Advancements Provide Ease of Operation

  • The latest software update delivers an improved user interface for easy operation and greater consistency across all Case IH seeding products.
  • The Precision Disk air drills interface now has a similar look, feel and functionality to that of the Precision Air™ 5 series air carts.
  • Available for the Precision Disk 500 air drills, an optional wireless flow blockage monitoring system uses acoustic sensors to “listen” to the sound of seed and fertilizer flow. Real-time continuous blockage status updates and blockage history tracking help pinpoint issues.



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 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 which is resistant to impacts, 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.

Single Fold

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 provides the stability to move the disk drill confidently, even at higher roading speeds.


Gain Efficiencies and Improve Yield Potential

Through our Customer-Driven Product Definition (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 new 500DS, you can add to those benefits saving time by seeding and fertilizing simultaneously.

Forward-Facing Seed Tube

  • More precise seed placement from tubes that direct seed towards 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 the highest setting to compensate for the travel arc of the gauge wheel on the arm..

Down Pressure Spring

  • Exclusive to Case IH is a unique variable down pressure spring on each row unit.
  • Provides pressure on an individual row unit to assist the row unit engagement in the ground.
  • Ensures even emergence and minimized compaction across terraces and uneven terrain.

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.
