Who This Machine Is For

• Compost producers — large production trommel for steady, high-volume organic material
• Topsoil and mulch yards — consistent screening with durable components
• Contractors with heavy workloads — built for continuous, demanding applications
• Recycling operations — reliable for ongoing screening of mixed and organic materials

What It Screens

• Topsoil — removes rocks and debris for resale-ready material
• Compost — separates finished compost from oversized material
• Mulch — produces consistent sizing for landscaping use
• Light C&D fines — handles smaller mixed debris and loose material

This is not designed for heavy rock or large aggregate processing. It is built for organic material and general screening applications.

Specs in Plain Language

3,500 hours on a 2019 machine — that averages to about 500 hours per year, which is typical for a production-class trommel. It is powered by a Deutz engine, known for efficiency and reliability in screening equipment.

This unit is equipped with a 5/8" punch plate drum, making it well suited for finer material separation such as compost and topsoil. The machine has had several key components replaced in 2024, including a new ERG cooler, heavy-duty brushes, and a new belt for the finished conveyor. Many rollers were also replaced around 3,400 hours, which helps reduce wear-related issues.

Machines in the SM 720+ class are built for continuous production, not small jobs. The larger drum and screening system allow for steady throughput depending on material type and conditions.
