These larger-sized Precision Disk 500 air drills help growers cover more acres in short planting windows.

Growers can take advantage of faster fill times by pairing these larger drills with Precision Air carts, the company says, available in sizes from 280 to 430 bushels in a tow-between or tow- behind configuration or 580 bushels in a tow-behind configuration.

The larger sizes of the precision disk also are an ideal match for higher-horsepower tractors, such as the company’s new Steiger, available with 682 maximum engine horsepower.

The rugged, reliable frames of the air drill hold up to changing field conditions – even going from no-till to conventional – with the main center frame oriented in a “V” to provide exceptional weight distribution and stability.

The new frame design also makes transport easier, as the wide profile of the transport wheels provide the stability to move the disk drill confidently, even at higher road speeds. Additionally, there are no daily maintenance requirements, allowing you to stay in the field longer.


Like other members of the precision disk family, these larger drills feature a parallel-link row unit for unmatched seed placement accuracy. The drills are available in either 7.5- or 10-inch row spacings.

Newly designed double-edged closing wheels, with three easy-to-adjust pressure settings, eliminate air pockets and ensure good seed-to-soil contact.

Hydraulic down pressure across the full width of the disk drill can be adjusted either manually or via an in-cab display option. They also provide the flexibility to seed across multiple crops and conditions:

  • Meter-roller options available with the company’s Precision Air delivery systems provide accurate metering across a wide range of crops, including soybeans, wheat, hybrid rice, milo and cover crops.
  • Single, easy-to-reach “T” handles select and lock in seeding depth with one adjustment – no tools necessary. Depth settings range from zero to 3.5 inches in 14 increments.
  • Patent-pending variable down-pressure springs put the right amount of pressure on individual row units for better penetration across varying residue and soil conditions.  FG
