Case IH Precision Disk™ 500 Air Drill

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.

Row Unit
Gain Efficiencies and Improve Yield Potential
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

For 30- and 40-foot toolbars, choose from 7.5-, 10- or 15-inch spacing configurations. When equipped with 7.5- or 10-inch spacing, the front or rear ranks can be hydraulically lifted and locked to seed with 15- or 20-inch spacing, respectively. The 25-foot toolbar is available with either 7.5- or 10-inch spacing.
The 500T is also available in a single-rank, 15 inch spacing configuration – ideal for soybean seeding.
Hitches
Find Your Match For Easy Maneuvering
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

Advanced Farming Systems (AFS)
Achieve Seeding Efficiencies with Data-Driven Decision-Making
Flow, Population and Blockage Monitoring
- Reduce unsightly skips from blocked seed rows and monitor seed population to ensure hitting target rates
- Optional on the Precision Disk 500, the wireless flow blockage monitoring system uses acoustic sensors to provide real-time continuous blockage status updates and blockage history tracking
- The Precision Disk 500T flow sensors provide accurate population estimates for larger seeded crops
- A bar graph on the Precision Disk 500T flow sensors displays target rates and seeding flow
Section and Rate Control
- Put seed, fertilizer and other inputs precisely where you want them using AFS section and rate control.
- Reduced overlaps combined with variable-rate application and precise product placement can help you save on inputs, improve agronomic performance and lower overall costs.
- Variable-rate application results in fewer trips across the field.
Guidance and Steering
- Achieve year-to-year repeatable accuracy at sub-inch levels with AFS AccuGuide autoguidance.
- Autoguidance helps reduce skips and overlaps; save on fuel and labor costs; better manage your seed, fertilizer and chemical inputs; simplify operation; and simply get more done every day.
Data Management and Analysis
- View, edit, manage, analyze and use your precision farming data — all in a single suite — with AFS software.
- Generate yield maps, precision maps and more from a single, integrated software package.
- Create soil sampling maps, generate and print reports, and import satellite imagery.
- Securely and easily import and manage all data sources using your AFS software.
