The Thiessen Undercutter loosens your soil with a robust 1060 High Carbon Steel cutting edge for easy harvest of carrots, garlic, parsnips and other root crops.

Recommended sizing: the undercutter should be at least 10-12 inches wider than the distance between your two outer rows. For example, if you have 3 rows 15 inches apart, that would be a 30 inch distance between the outside rows and a 42 inch undercutter would be ideal.
