Coolamon Launches 148,000-Liter Chaser Bin, the Largest in Its Segment

The Australian manufacturer has introduced a 120-tonne chaser bin with a 148,000-liter capacity, setting a new benchmark in its category. The unit combines high capacity with rapid unloading performance. With a discharge rate of nearly 68,000 liters per minute and a four-axle configuration, the new model targets high-efficiency harvesting logistics.

The Australian company Coolamon has unveiled its new 120T chaser bin, featuring a capacity of 148,000 liters (120 tonnes), positioning it as the largest unit globally in the chaser bin segment—grain carts designed to support combine harvesters during harvest operations.

The Australian manufacturer has established itself as a global benchmark in large-capacity grain handling equipment. Its latest launch, a 148,800-liter chaser bin, is the largest of its kind worldwide.

High-Capacity, High-Speed Performance

Beyond its record capacity, the 120T stands out for its unloading speed. With a discharge rate of 67,800 liters per minute, the unit can be emptied in just over two minutes, optimizing turnaround times during harvest.

The machine operates on a four-axle chassis equipped with eight high-flotation tires, designed to reduce soil compaction while maintaining stability under full load.

According to the manufacturer, the 120T represents “the largest and most advanced chaser bin currently available on the market.”

Market Positioning

The new model ranks as the largest chaser bin worldwide within the harvest support equipment segment.

While larger grain handling solutions exist, these typically fall into the mother bin category—high-capacity units used as logistical buffers that remain stationary at field edges rather than operating within the crop area.

In this segment, Coolamon is also a global reference, offering an extensive product range that includes the CMB200T, with a capacity of 240,000 liters.

Market Implications

The introduction of ultra-high-capacity chaser bins reflects the growing scale of harvesting operations and the need to improve in-field logistics efficiency. Equipment with faster unloading rates and higher volumes can significantly reduce combine downtime, particularly in large-scale farming systems.
