Handy harrow DMI's Tiger-Tine harrow can be hooked behind a field cultivator. Because it's on parallel linkage, the harrow floats with the cultivator. The machine's indexed tines on four bars create smooth, level fields by evenly disturbing soil and residue, breaking clods and killing weeds. Each row of tines can swing forward to relieve pressure on short turns. The company claims the unit also offers outstanding flexibility. Three tine-angle choices are available: 5ø for heavy soils with minimal residue, 20ø for average soils and residue, and 35ø for extremely heavy residue. Contact DMI Inc., Dept.
