Features
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

Precision guidance technology ensures optimal strip-till performance by maximizing nutrient utilization and improving seed placement accuracy. This technology enables efficient execution through features like Active Implement Guidance, AutoPath™, and shared signals from StarFire™ receivers, enhancing overall productivity.
Integrated Fertilizer System

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.
