Press Wheels and Shanks

The Flexi-Coil 5000HD air drill can be equipped to give you the on-row packing performance you need. By matching the press wheel to your opener style, your seed has the best chance for fast, even germination.

Steel
Steel press wheels are used in sandy and rocky conditions. A V-profile concentrates packing pressure onto a smaller area for higher pressure over the seed, and the shape of the furrow also provides protection from wind and water erosion.



  • 4 ½-inch steel press wheels spread the packing pressure over a wider area and are ideal when spreading seed or for wide double-shoot applications. The soil profile is the flattest of the steel wheels. Due to its width, this press wheel is not available in row spacing configurations under nine inches.
  • 3 ½-inch steel press wheels work well with openers that spread seed up to 3 ½ inches, or with narrow double-shoot openers. The soil profile is a wide V-shape. This press wheel is available in all row spacing configurations.


Rubber
In heavy, sticky soil conditions, rubber press wheels flex to shed the soil. The flatter profile rides over a wider area for less packing pressure—just right for soils where too much packing can be a problem.



  • 5 ½-inch rubber press wheels offer on-row packing in wide seed spread applications. Due to its width, this press wheel is not available in spacing configurations less than nine inches.
  • 4-inch rubber press wheels are effective for many applications where seed is spread up to four inches. Due to its width, this press wheel is not available in spacing configurations less than nine inches.
  • 3-inch rubber press wheels can be used with knife openers or when spreading seed up to three inches. It also works for narrow double-shoot applications. This press wheel is available in all row spacing configurations.
  • 5 ½- and 6 ½-inch pneumatic walking beam-style rubber tires are also available.
  • Choose trip assemblies to match your soil conditions. You can equip the 5000HD air drill with 350-pound trips for most conditions, or 550-pound trips for double-shoot applications and tough conditions.
