Compost turner for triangular windrows

The new Topturn X4500 brings high-end performance to the entry level category. The X4500 packs the proven functionality of the X series in a scale that is a perfect fit for small and medium-size composting operations.

A robust frame in a pioneering new design, high performance hydraulics and generously dimensioned drum mean high throughput in all working scenarios. All engines meet the latest exhaust requirements. Generously dimensioned cooling systems keep them running smoothly even under full load and high ambient temperatures.

Further plus points are hydraulically extended maintenance platforms for ready access, and low wear costs through double-use turning blades.
