1999 Morbark 1300

4,300 hours on a 1999 Morbark 1300 — that’s roughly 165 hours per year, and the engine has already been rebuilt with paperwork. That combination of low annual use and major rebuild work adds real value for the next owner.

Who This Machine Is For

• Land clearing contractors — handles brush, stumps, and large wood waste
• Recycling yards — processes wood waste into mulch or reusable material
• Forestry operations — built for grinding whole trees and dense timber
• Buyers looking for rebuilt components — major work already completed

What It Grinds

• Whole trees and large timber — tub design allows feeding oversized material directly
• Stumps — breaks down dense root systems into grindable material
• Brush and green waste — reduces volume 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 an 800HP CAT 3412 engine. That level of horsepower is well-suited for production grinding and can handle large, dense material without constant slowdown.

With 4,300 hours over 26 years, you’re looking at about 165 hours per year. That’s low usage for a tub grinder, especially compared to machines that run daily in production environments.

The engine was completely rebuilt at 8,500 hours, and paperwork is available. In addition, a new ECM was installed last year, along with a tub rebuild, new rotor bearings, and a balanced drive shaft. That’s a significant amount of recent work that can reduce downtime and improve reliability.

The undercarriage is in excellent condition and ready for transport, which matters when moving a machine of this size between job sites.

The Morbark 1300 is known as a production tub grinder. The open tub design allows operators to load large material without pre-processing, helping keep jobs moving efficiently.

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