Reliable, Durable, & EfficientAeromaster Compost Turners are designed and built to last for years of rigorous use in the rough environment of a compost operation. With a heavy-duty tube steel construction and reinforcing steel gussets on major stress points, we minimize common failure points and strengthen the overall structure. The optimized design of the turner also reduces the stress on individual components which leads to an incredibly efficient, durable, and long-lasting compost turner!

Requires Less Power - Saving FuelThrough extensive research and years of experience, we have gained a better understanding of material, air, and particle management of the turner's drum. By reducing the drum speed and optimizing the paddle design we have engineered our drums to require less effort to move a greater amount of material in a windrow. Requiring less effort reduces the horsepower requirements of the tractor, saving you fuel, and more importantly money!

Lowest Maintenance & Repair CostsWe engineer our turners to require fewer complex components and wear points, which means there are fewer opportunities for failure. This lessens the chance for breakdowns and repairs, and also minimizes the amount of maintenance required to keep your turner running smoothly. This means you spend more time on the site making compost, and less time in the shop!
