1994 Maxigrind 425G

Ram-fed grinder with cab and loader in really good overall shape. Clutch, conveyor bearings, mill shaft, and mill bearings are all solid. Newer tips, wear plates, and drive belt. Good tires. Runs and operates as it should.

Best suited for construction debris, asphalt, or concrete block. Can handle chunk wood but this is not it's ideal use. Only reason for selling is an upgrade to a newer machine.

1994 Maxigrind 425G

1994 Maxigrind 425G powered by a 425HP CAT 3406 — a ram-fed horizontal grinder built for heavy-duty applications like C&D material and block processing. This unit stands out for its solid mechanical condition and specialized use.

Who This Machine Is For

• Recycling yards — processes construction debris and block material
• Demolition contractors — handles C&D waste efficiently
• Asphalt and concrete recyclers — ideal for dense, heavy material
• Operators looking for value — solid machine with key components in good shape

What It Grinds

• Chunk wood — capable, but not its primary application
• Heavy material — built for tougher grinding jobs

This is not a chipper. It uses a hammermill system, so the output is ground material, not uniform chips.

Specs in Plain Language

This unit is powered by a 425HP CAT 3406 engine. That level of horsepower places it in the mid-production class, with enough strength to handle dense materials like concrete block and asphalt.

This is a ram-fed grinder, which means material is pushed into the mill using a hydraulic ram instead of a conveyor. That design is especially effective for heavy, bulky materials like C&D debris.

The machine includes a cab and loader, allowing for more controlled feeding and operation directly from the unit.

Mechanically, this machine is in really good overall shape. The clutch, conveyor bearings, mill shaft, and mill bearings are all reported to be solid — these are critical components for long-term performance.

It also features newer tips, wear plates, and a drive belt, along with good tires, all of which reduce immediate maintenance needs.

This grinder runs and operates as it should, making it a ready-to-work option for the right application.

Important note: while it can handle wood, it is not ideal for that purpose. This machine is best suited for construction debris, asphalt, and concrete block processing.
