2007 Morbark 6600

13,900 hours on a 2007 Morbark 6600 — but this machine was fully rebuilt by Morbark at 7,000 hours, including the engine. That rebuild significantly resets wear on major components and adds value for continued production use.

Who This Machine Is For

• Large land clearing operations — handles high volumes of brush, timber, and stumps
• Recycling yards — processes wood waste into mulch or reusable material
• Forestry contractors — built for grinding whole trees and dense material
• Operators needing high horsepower — production grinder with rebuild history

What It Grinds

• Whole trees and large timber — tub design allows feeding oversized material directly
• Stumps — breaks down dense root systems with high horsepower
• Brush and green waste — reduces volume quickly for hauling or reuse
• Construction wood waste — processes pallets, lumber, and mixed debris

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

Specs in Plain Language

This unit is powered by a 1,050HP CAT C27 engine. That level of horsepower puts it in the high-production class, capable of handling large, dense material without slowing down under load.

With 13,900 hours over 18 years, you’re looking at about 770 hours per year. That reflects a machine that has been used in production environments. However, the full rebuild at 7,000 hours — including the engine — is a key factor that reduces concerns around long-term wear.

The Morbark 6600 is known as a production tub grinder. The open tub design allows operators to load large material without pre-processing, which helps keep jobs moving efficiently.

The machine is reported to have all functions working as they should, which is important for a grinder in this class. Buyers should still evaluate wear components such as the mill, bearings, and drive system as part of normal due diligence.

If you’re comparing options, you can also view other tub grinders or check horizontal grinders if your operation prefers controlled feeding.
