The Prescription Tillage Technology Seed Opener disc is designed with a tooth that cuts better than conventional blades while driving rotation to stop sidewall smearing. They fracture at the bottom of the trench to get small roots out and also fracture sidewalls for easier closing. Closing discs for Case planters with the same technology and built-in depth control are available. A no-till coulter that features the same tooth design that stops hair pinning is also available.
