The Root Digger (also called the Potato Digger) is used to harvest small-scale crops of root vegetables. The round tines extending from the implement sifts through worked soil, making most of the vegetable visible and can be easily collected. It's important to note that the Root Digger can only burrow into the soil as deep as it's been worked.
The Root Digger can harvest potatoes very efficiently down the center of the row. For more delicate root crops such as garlic, onions, and turnips, the implement should be planted to the side of the row to avoid crop damage.
