AEROMASTER PT-170
Pull-Type Compost Windrow Turner

The Aeromaster PT-170 pull-type compost windrow turner is designed for sites producing 20,000 tons or more of finished compost per season. Its innovative design allows the operator to aerate, blend, and add water & inoculants in a single pass.
The rugged PT-170 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 switched to the transport position, the PT-170 is ready to be pulled down the road to the next location.
