This heavy-duty spring tine is the SV-type tooth for a cultivator. It mounts to the frame and carries the coulter at its lower end, transmitting downward force to maintain working depth in the soil. The tine flexes to pass over obstacles and returns to its set position, reducing shock loads on the frame and the coulter assembly. A worn or bent tine alters the coulter’s attack angle, leading to uneven soil penetration and inconsistent residue flow. The original manufacturer’s geometry matches the frame clamp and the coulter bracket without requiring shimming or modification.
