20" DT20 Walk-Behind Overseeder, 7524472

Heavy-duty and built to perform, the Bobcat DT20 Walk-Behind Overseeder places seeds directly into soil slits for fast germination and unmatched seed-to-soil contact, aeration, and overseeding. The DT20 can be easily converted to dethatch, power rake or verticut by installing a flail reel or choice of fixed blade.

    • In addition to overseeding, the DT20 can be converted to dethatch, power rake or verticut by installing a flail reel or choice of fixed blade (in related parts below)
