20/20 Airforce

Down Force Control

Too little down force means shallow plants

Too much down force means restricted root growth

AirForce® means automatic control.

Root zone compaction is caused when there is excessive down force applied to the row unit during planting. That compaction cuts yields by:

  • Reducing germination rates and lowering plant count
  • Increasing plant stress reducing ear girth and length
  • Stressing plants at pollination during dry years with hot summers

Until now, corn growers had no way to measure the amount of weight carried by the row units . . . and no way to increase or decrease weight for each soil type and tillage condition.

The 20/20 SeedSense® system teams with 20/20 AirForce to automatically measure and manage down force to make sure you run as light as possible, while maintaining the ground contact that assures uniform seeding depth.

SeedSense includessmart pins that measure the weight on the row unit and calculates the amount of excess weight that could be removed while still maintaining full planting depth.

Down Force Sensor Install

AirForce takes the information from SeedSense and uses air to automatically increase or decrease the weight on the row unit. The row units will now run as light as possible . . . with just enough weight to keep the row units proper depth.

20/20 AirForce® takes a costly problem that you had no way of managing and fixes it automatically. Taking signals from the 20/20 SeedSense®, the system increases or decreases air pressure in row-unit airbags to increase or decrease weight on the row unit. SeedSense sensors constantly report row unit weight and excess weight (margin) that could be removed. Then AirForce responds – automatically.

Here’s the secret that allows AirForce to rapidly respond to changing ground conditions. The small lift bag can inflate and deflate quickly. It works against the traditional down force system (springs or airbags) to “dial in” the correct row-unit weight for each condition.

AirForce includes an air reservoir, a high duty-cycle compressor plus airbags and mounting brackets to match your planter configuration. Simply bolt the airbag mounting brackets and pressure bags on your existing parallel arms.

Deere, CNH, White and Kinze – there is an AirForce system for most planters. We configure your system after analyzing your current down force system – springs or airbags. Then, we add either lift bags, or down and lift bags to provide the control you need to manage row unit weight.

Kinze Side Springs

For planters with springs along the parallel linkage or existing air bags, AirForce simply adds an up lift airbag to counteract the forces from the springs or bag.

T Handle
For planters with the adjustable springs mounted between the parallel arms, the system replaces the springs with a combination unit that includes a down force bag and an up lift bag.


For planters with central fill systems (no seed boxes on the row unit) with the down force airbags, we provide a larger, hydraulically driven compressor that can rapidly exchange air in your existing airbags. Because there is no seed weight on the row unit, lift is frequently not needed.

20/20 SeedSense gives you one-touch automation
Select an operating mode that fits your field or area:

  • Light – gives you an extra light footprint for easily compactable soils or wet soils.
  • Medium – is the primary setting for most conditions and will be the default setting.
  • Heavy – is for areas where excessive clods, rocks or speed require some extra holding power.
