A75 Compost Turner

World’s. Largest. Turner. Period!

The BACKHUS® A75 compost turner is built for maximum capacity, extreme durability, and intelligent operation. This compost monster can turn windrows up to 24’-6” wide and 11’ tall. The massive 71” diameter drum of the A75 homogenizes your feedstock like no other compost turner can, and its high torque and armored drum tools throw material easily, getting all the way to the bottom of the pile each and every time.

Engineered with smart technology and innovative mechanics, the turner can almost run itself. Detailed feedback and control allows the operator to monitor all aspects of performance, while the electronic control systems automatically adjust to the compost to ensure the highest throughput possible.

Better compost, in fewer turns, in less time. That’s the BACKHUS advantage!
