Seed Openers
To help create a narrow profile for easier insertion into the soil, planters with evenly matched seed opener discs (e.g., John Deere, Kinze, White) should be pinched together along the periphery of the blades at the soil entry point Close enough to firmly hold a business card between the discs.
Planters with staggered leading and trailing discs should have discs only slightly separated, perhaps 0.06 inches, maintaining a narrow space between edges of the lead and trailing discs but allowing the trailing disc to run in the furrow cut by the leading disc.
