2020 VERMEER TR521

It is already fitted with 1/4-inch screens for operations producing a fine finished product.

Who This Machine Is For

• Topsoil producers — the 1/4-inch screens separate fine soil from roots, rocks, and oversized material.
• Composting operations — the rotating drum sizes finished compost before sale or reuse.
• Landscape supply yards — the wheel-mounted chassis works well for operations that move between sites.
• Material recyclers — the TR521 can separate several organic and light aggregate materials by size.
• Buyers comparing trommel screens — this machine combines a five-foot-diameter drum with a road-transportable design.

What It Screens

• Topsoil — removes oversized debris to create a fine soil product.
• Compost — separates finished material from larger pieces that need more processing.
• Sand — sorts material by size when moisture and feed conditions allow.
• Mulch — removes fines or separates material into a specific product size.
• Light aggregate — handles suitable gravel and similar material within the machine’s design limits.

The 1/4-inch openings can restrict production with wet, sticky, or clay-heavy material because fine screens may plug faster.

Specs in Plain Language

The frame and Cummins engine each have 4,550 hours. Over six years, that equals approximately 758 hours per year. The 120 HP Cummins engine provides power for the drum, hopper, and discharge conveyors, while the Tier 4 Final rating meets the emissions standard listed for this TR521 generation.

The TR521 uses a five-foot-diameter drum and a five-cubic-yard hopper. The hopper provides room for steady loader feeding, while the drum separates material as it moves through the installed screens. The 1/4-inch screens determine the fine-product size, but actual production depends on moisture, material density, contamination, and operator settings. Our trommel screen guide explains how drum and screen selection affect the finished product, and we also carry trommel screen parts.
