SINGLE DISC FURROW OPENER WITH WALKING BEAM |
摘要 |
A furrow opener apparatus has an arm assembly adapted at a front end thereof for pivotal attachment to a seeder frame. A single disc is rotatably attached to the arm assembly about a disc axis at an angle to the travel. A walking beam is pivotally attached to the arm assembly rearward of the disc about a beam axis transverse to the travel direction. A bias element exerts a force on the arm assembly such that a downward bias force is exerted on the walking beam at the beam axis. A packer wheel is rotatably attached at a rear end of the walking beam, and a gauge wheel is rotatably attached at a front end of the walking beam. The gauge wheel is configured to roll along the ground adjacent to the leading face of the disc, and the packer wheel is configured to roll along the furrow.
