WALKING BEAM FURROW CLOSING SYSTEM FOR DISC SEEDER

摘要

An agricultural disc opener is operable to be advanced in a forward direction along the ground to plant seed. The disc opener includes a suspension, a disc blade, a seed firming wheel, and a closing wheel. The suspension includes an elongated closer/firmer walking beam pivotally mounted relative to a suspension for pivoting about a lateral beam pivot axis. The wheels are rotatably mounted on the walking beam on opposite forward and aft sides of the beam pivot axis, with the walking beam configured to pivot as the wheels travel over the ground.

1. An agricultural disc opener operable to be advanced in a forward direction along the ground to plant seed, said agricultural disc opener comprising:
a vertically adjustable suspension; a disc blade operably supported by the suspension to open an elongated furrow in the ground as the disc opener is advanced in the forward direction, with seed being deposited into the open furrow; a seed firming wheel located rearwardly of the disc blade and configured to press the seed downwardly into the furrow; and a closing wheel located rearwardly of the seed firming wheel and configured to deposit soil into the furrow to at least partly cover the seed, said suspension further including an elongated firmer/closer walking beam pivotally mounted relative to the suspension for pivoting about a lateral beam pivot axis, said wheels being rotatably mounted on the walking beam on opposite forward and aft sides of the beam pivot axis, with the walking beam configured to pivot as the wheels travel over the ground.
