At Kooima Ag, our focus is helping friends farm better by creating new products that help in everyday operations. Our high-capacity compost windrow turner, the Trner Composter, has many features and advantages that make it stand out against the competition.

Proudly made in the USA, the Trner Composter has a tough, box design. This heavy-duty design is built to handle tough materials and is proven in harsh conditions! We tested the Trner Composter against competitors and found, in most cases, the Kooima Ag turner was able to process significantly higher tons of raw material. The Trner Composter is typically used for manure and larger compost materials. We have also used the Trner Composter for animal mortality composting (see tips below).

The Trner Composter has a higher clearance making it more suitable for larger piles. The turner's hydraulically driven wheel offers more speed and traction. There is a 3" diameter through shaft on the drum, adding more rigidity and throughput. This drum is designed to throw material back farther with less horsepower. The Trner Composter is road towable with a tongue that easily pivots for transportation. Our patented paddle design (U.S. Patent # 10,617,061; CAN. Patent # 3,020,147) helps incorporate more oxygen into the pile. It's easy to service and has the lowest operation cost per ton!
