Single disc furrow opener with walking beam
First Claim
1. A furrow opener apparatus comprising:
- an arm assembly adapted at a front end thereof for pivotal attachment to a seeder frame such that a rear end of the arm assembly can move up and down;
a single disc rotatably attached to the arm assembly about a disc axis oriented at a horizontal disc angle to the operating travel direction such that a leading face of the disc moves soil toward a first side of the disc when the disc is engaged in the ground to form a furrow;
a walking beam pivotally attached to the arm assembly rearward of the disc about a beam axis oriented transverse to the operating travel direction such that the beam axis and disc axis are fixed with respect to each other during operation;
a bias element operative to exert 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 rotatably attached at a rear end of the walking beam about a packer wheel axis, rearward of the beam axis;
a gauge wheel rotatably attached at a front end of the walking beam about a gauge wheel axis, forward of the beam axis;
wherein 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.

Abstract
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.
