Lifting mechanism for a seeding machine row cleaner
First Claim
1. A seeding machine comprising:
- a frame;
a rockshaft rotatable about an axis transverse to a forward direction of operation of the seeding machine;
a furrow opener mounted to the rockshaft to pivot vertically;
a row cleaner attached to the furrow opener to pivot vertically;
a lifting mechanism on the frame and coupled to the furrow opener by a first linkage and to the row cleaner by a second linkage wherein the row cleaner is lifted in response to lifting of the furrow opener.

Abstract
A suspension for a row cleaner associated with a furrow opener in a seeding machine includes a lifting mechanism to lift the row cleaner when the furrow opener is lifted. The lifting mechanism includes a bell crank having an input crank arm coupled to the furrow opener by a fist linkage to rotate the bell crank when the furrow opener is lifted. An output crank arm of the bell crank is coupled to the row cleaner by a second linkage to lift the row cleaner when the bell crank shaft is rotated by lifting of the furrow opener. The second linkage is flexible, such as a rope, to enable the row cleaner to lift to avoid obstacles without back driving the bell crank to also lift the furrow opener. The flexible second linkage also enables the row cleaner to be equipped with a lock to retain the row cleaner in a raised position for use of the seeding machine in conditions not requiring a row cleaner.
