Abstract
A double-coil spring tine is pivotally attached to a channel-shaped mounting bar of a harrow unit by a removable bracket. The portion of the tine connecting the coils is held loosely next to the mounting bar by the bracket so that the entire tine can pivot about the axis of the attaching portion. The portion of the tine on either side of the bracket is placed in tension rather than subjected to bending. Tines are individually replaceable without need to disassemble the mounting bar.
