2016 Morbark 6600

6,762 engine hours on a 2016 Morbark 6600 — with 5,315 grind hours, that’s roughly 780 engine hours per year on a 1,200HP production grinder. This is a high-output machine built for serious volume.

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 maximum production — top-tier horsepower for demanding jobs

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 1,200HP CAT C32 engine. That level of horsepower places it in the ultra high-production class, capable of handling large, dense material continuously without slowing down.

With 6,762 engine hours over 9 years, you’re looking at about 780 hours per year. That reflects steady production use, which is expected for a grinder in this category.

Grind hours are 5,315, which is an important distinction. It shows actual time spent grinding versus total engine runtime, giving better insight into wear on the mill and grinding components.

The Morbark 6600 is a horizontal grinder with a controlled feed system. This allows for more consistent material sizing and improved efficiency when processing mixed or variable feedstock.

Machines in this class are designed for high-volume operations where throughput and uptime are critical. Buyers should evaluate wear components such as the mill, teeth, and conveyor system as part of normal inspection.

If you’re comparing options, you can also view other horizontal grinders or check tub grinders if your operation prefers gravity-fed loading.
