How deep can an excavator stump grinder cut?

The cutting depth of an excavator stump grinder can vary based on the specific model and attachment type. Generally, these grinders can reach depths of up to 12 inches below the ground surface, effectively removing the entire stump and root system. This depth is crucial for preventing regrowth and ensuring that the area can be reused for planting or landscaping. When selecting a stump grinding attachment, be sure to check its specifications to ensure it meets your project needs and can handle the desired cutting depth.
