Pull-Type Compost Windrow Turner

The Aeromaster PT-120 pull-type compost windrow turner is the ideal turner for sites producing up to 5,000 tons of finished compost per season (actual site capacity will vary with the length of the productive season). Its innovative design allows a single operator to aerate, blend, and add water & inoculants in a single turning pass.

The rugged PT-120 is built from a simple design using heavy duty components to maximize machine life while minimizing required maintenance. Driveline safety is provided by an Auto trip PTO driveline that disengages if it encounters excess stress. When the drive train stops turning, the clutch resets, and turning can restart immediately.

The retractable drum hydraulically lifts out of the windrow in seconds at any time to allow inspection of the windrow inside profile or exit the windrow for any reason. When locked in the vertical transport position, the PT-120 is ready to be pulled down the road to the next location.
