2010 Morbark 4600

17,442 hours on a 2010 Morbark 4600 — that’s roughly 1,190 hours per year on a production horizontal grinder. This is a working machine that has been consistently used and maintained in active operation.

Who This Machine Is For

• Large land clearing operations — handles high volumes of brush, timber, and stumps
• Recycling yards — processes wood waste into reusable material
• Forestry contractors — built for grinding whole trees and dense material
• Operators needing production output — proven machine that grinds daily

What It Grinds

• Brush and green waste — reduces volume for hauling or reuse
• Wood waste — processes pallets and scrap lumber
• Whole trees and large timber — handles heavy material with controlled feed

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 CAT 3412 engine. That level of horsepower places it in the high-production class, capable of handling large, dense material continuously.

With 17,442 hours over 15 years, you’re looking at about 1,190 hours per year. That reflects heavy production use, which is expected for a machine in this class.

The engine and clutch have both been rebuilt, which is a major value point. These are critical components, and having them rebuilt helps extend the usable life of the machine.

Additional updates include new discharge and belly belts, along with the infeed and mill being redone at approximately 13,000 hours. These are key wear areas that directly impact grinding performance and reliability.

This machine is reported to be very well maintained and currently grinding daily, which is a strong indicator of operational condition.

The Morbark 4600 is a horizontal grinder with a controlled feed system, allowing for consistent material sizing and efficient processing in high-volume operations.
