Seeder with trailing arm and hoe-type mid row bander |
摘要 |
A seeding and fertilizing apparatus comprises a plurality of seed assemblies each comprising a trailing arm pivotally connected at a front end thereof to the frame and a packer wheel rotatably attached to rear end thereof. A seed furrow opener is attached to the trailing arm ahead of the packer wheel which rolls along the seed furrow created by the opener. A vertical position of the seed furrow opener with respect to the packer wheel is adjustable, and a bias device is operative to exert a downward bias force on the trailing arm. A plurality of fertilizer assemblies each comprises a fertilizer knife mounted to the frame such that a vertical position of the fertilizer knife with respect to the implement frame is adjustable. The seed assemblies and fertilizer assemblies are oriented laterally such that each fertilizer furrow is located between adjacent seed furrows.
