Features

Integrated Fertilizer System

Side view of an ST16 drawn 40-ft strip till's yellow integrated fertilizer tanks, with StarFire 7000 receiver mounted on the back

The integrated fertilizer system allows for precise nutrient application with stainless steel meters and scales for reliable performance. The system reduces soil compaction and increases operational efficiency and profitability, holding up to 20,000 lb (9072 kg) of fertilizer and utilizing advanced technology for consistent delivery.

Versatile Tillage Options

The strip till offers flexibility with dual coulter or shank tillage options. Dual coulters allow for early field access, making it easier to prepare the seedbed, while shanks offer increased soil fracturing in tougher conditions and permit the application of anhydrous ammonia. This adaptability is ideal for a variety of field conditions.

Precision Guidance Technology
