Ideal for rocky soil conditions! Three-position rotatable tooth – it’s like having three teeth in one! The Greenteeth® design is unique in that the tooth can be quickly rotated three times to give your machine three sharp cutting edges before the tooth needs to be sharpened. The 500 Series Green Standard Dish tooth has a concave that is a bit shallower compared to the Red Deep Dish and is a better choice for rocky soil conditions. The 500 series are appropriate for smaller units in the market, typically under 20hp.
