High Production Yard Waste Grinders

Primary grinding is the first reduction stage where large yard waste, logs, brush, limbs, and mixed green debris, is processed into a manageable size. CBI machines like the 6800BT or 6400CT are ideal thanks to their high horsepower, wide infeed openings, and heavy-duty rotors. The goal is fast volume reduction and a consistent base material ready for secondary grinding or composting. This stage handles dirty, bulky feedstock with ease, making it perfect for municipalities, land clearing, and large yard waste facilities.

The CBI 6400CT is a high-capacity grinder built for primary yard waste reduction. Its 1,200 HP engine and 66" x 46" down-turn rotor rapidly process bulky brush, limbs, and storm debris in one pass. The heavy-duty infeed and welded hog box handle dirty, fibrous material without plugging, while metal detection protects against contaminants. With interchangeable screens for sizing control, the 6400CT delivers reliable, high-volume performance in demanding yard waste operations.

The CBI 5400BT delivers up to 765 HP in a robust, track-mounted platform built for primary yard waste grinding. With four field-swappable rotors, it aggressively processes brush, limbs, whole trees, and mixed green waste in a single pass. Its durable design handles dirty and fibrous material with ease, reducing bulky yard debris into a consistent base product ready for secondary grinding or composting. High throughput and uniform sizing make the 5400BT a powerful and efficient solution for municipalities, land clearing, and large yard waste operations.

The CBI 5800BT delivers up to 1,000 HP in a compact, track-mounted design, making it ideal for secondary yard waste grinding. Its mobility and efficiency in tight job sites allow high production rates while producing a consistent, fine end product suitable for mulch or compost feedstock. Built to handle fibrous, wet, and mixed organic materials, the 5800BT’s durable rotor and screening system ensure reliable performance and uniform sizing for high-volume secondary grinding operations.

The CBI 5900T delivers up to 755 HP in a powerful, track-mounted design, making it ideal for secondary yard waste grinding. Its mobility and efficiency in tight job sites allow high production rates while producing a consistent, fine end product suitable for mulch or compost feedstock. Built to handle fibrous, wet, and mixed organic materials, the 5900T’s durable rotor and discharge system ensure reliable performance and uniform sizing for high-volume secondary grinding operations.
