Montag Auto-Steer Cart

Montag Auto-Steer Cart

Our complete fertilizer application system helps you reap the benefits of deep band fertilizer; it adapts to most applications when liquid or dry fertilizer banding is preferred. Our high-capacity, auto-steer fertilizer cart “steers” itself to precisely follow in the tracks of any implement, thereby staying off your rows. Designed to band granular fertilizer, it can be used in any application such as fall, spring- or side dress using liquid or dry fertilizer.
