STM-32 Trapezoidal Pile Turner

THE compost turner for pile composting.

Not all compost is created in rows. Solid beds of compost, sometimes called aerated static pile (ASP) compost systems, continuous stack composting, or trapezoidal pile composting, eliminate the space between windrows and require a different type of compost turner to minimize odors and make great compost.

Introducing the Menart STM-32 Trapezoidal Pile Turner, the perfect machine for maintaining indoor or outdoor trapezoidal pile compost curing operations.

Featuring an efficient and powerful 375 hp Cat® C9.3B EPA Tier 4 Final diesel engine, the Menart STM-32 compost turner can easily handle 12’ trapezoidal pile heights and discharges turned compost with its side conveyor.

Pile it, then turn and earn with the Menart Trapezoidal Pile Compost Turner!
