Each assembly has steel traction fingers and 9.5" polyurethane finger discs on a support shank. Angled in, Finger Weeders turn together, gently agitating the soil near the crop and uprooting thread-stage weeds. For use on many established crops, including brassicas, lettuce, and especially carrots. For greatest efficiency, use in conjunction with other attachments, such as Preci-Discs, for concurrent in-row and inter-row weeding. Includes spring-loaded mounting arm, 16" toolbar, two Y-bolts, and two finger weeders with upright brackets. Stiff fingers. For standard (medium) soils. Yellow. Made in France by Terrateck. NOTE: For use with the Terrateck Double Wheel Hoe only. Also available in a model designed for soft or sandy soil.
