This spring tine with an integrated coulter is an S-shaped tooth for a tillage unit. It mounts to the tool bar and carries the coulter that opens the seed furrow. The S-bend allows the tine to deflect when it strikes an obstruction, then return to its working depth without permanent deformation. A worn or broken tine causes inconsistent coulter penetration and uneven seed placement. The manufacturer machines the mounting hole and tine profile to match the original assembly geometry, so the coulter aligns correctly with the seed tube without shimming.
