1994 Maxigrind 425G

1994 Maxigrind 425G powered by a 425HP CAT 3406 — a horizontal grinder built for wood waste processing with key mechanical updates already completed. This unit is ready to go straight to work.

Who This Machine Is For

• Tree service companies — handles brush, limbs, and organic debris
• Recycling yards — processes wood waste into reusable material
• Mulch producers — suitable for consistent wood grinding applications
• Operators looking for value — updated machine with solid components

What It Grinds

• Brush and green waste — reduces volume for hauling or reuse
• Wood waste — processes pallets and scrap lumber
• Chunk wood — handles larger pieces with controlled feed
• Organic material — ideal for mulch and wood-based products

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