Abstract
A disc opener assembly for an agricultural planter includes a coulter disc formed without a pilot hole for the spindle of the mounting hub. The mounting hub is formed without the spindle such that the coulter disc is supported directly in a cantilevered manner from the mounting flange of the mounting hub. The coulter disc is formed with fastener holes aligned with mounting holes in the mounting flange for the passage of fasteners to affix the coulter disc to the mounting flange. The fasteners are countersunk into the coulter disc to present a smooth exterior surface. A seal is positioned between the mounting flange and the coulter disc to prevent the entry of dirt and debris into the mounting hub. No dust cap on the exterior surface of the coulter disc is required with this configuration which improves the operation of the disc opener assembly.
