DUTZI (brand of KD Agrartechnik GmbH)

KD Agrartechnik GmbH is a German manufacturer of agricultural machinery headquartered in Bad Nenndorf, Lower Saxony. The company brings together two long-established brands: KNOCHE (founded in 1790) and DUTZI (founded in 1904), representing over 350 years of combined experience in mechanical engineering. The company develops and manufactures innovative agricultural machinery for active and passive soil cultivation, with a focus on mechanical soil compaction relief. DUTZI's core philosophy is based on the principle of working the soil without turning or mixing it, preserving soil structure while ensuring loose, well-aerated soils with active soil life and deep root growth. The product range includes rototillers (KR series), front subsoilers (FL series), and rear subsoilers (HL series), which can be combined into efficient OnePass systems for deep loosening, crumbling, seeding and reconsolidation in a single pass.
