3-way trailed harrows feature a 3-way pulling action giving you the option to choose passive, aggresive or smooth to suit your ground conditions.
Passive - reverse the mat so tines face backwards to give less ground penetration and a smoother action.
Aggressive - ensure tines face forwards for vigorious, deeper ground penetration, ideal for harder ground
Lighter - turn the mat upside for lighter harrowing - ideal for re-seeding.
