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 Red Deep Dish tooth is more aggressive and has a more deep concave edge compared to the Green Standard Dish. These teeth are a better choice for rocky soil conditions where there is LESS THAN 25% rock in the ground. The 500 series are appropriate for smaller units in the market, typically under 20hp.
