18-5/8″ PD500 Ingersoll Hi-Hard Opener Disc

The Cutting Disc is responsible for cutting through residue and opening the seed trench. It works in tandem with the seed boot and gauge wheel to deliver and precisely place the seed at the correct depth. Worn discs do not cut properly and may push residue into the trench causing degraded seed-to-soil contact. Worn discs also cause excessive wear to the seed boots as they ride in the shallower trench, leading to poor seed placement and greatly reduced seed boot life. Red E’s exclusive USA and Canada made Ingersoll Hi-Hard double bevel razor edge extended wear disc maximizes both longevity and sharpness.



  • New Ingersoll Hi-Hard discs utilize advanced heat-treating processes to achieve some of the hardest discs in the industry
  • The 18-5/8″ diameter coupled with higher grade steel and hardness can last over 50% longer then standard 18″ competing discs
  • High hardness material helps retain a sharp cutting edge to ensure accurate seed placement
  • Discs should be replaced when disc diameter becomes less than 17″
  • Made in USA and Canada and available exclusively through Red E
