Built for land-clearing and pipeline right-of-way operations, the HG6800TX horizontal grinder offers a high-horsepower engine on a tracked machine with a compact design. Featuring 950 hp (708 kW) in a 92,000 lb (41,730.5 kg) class, and an infeed design designed specifically for feeding larger materials such as whole trees and large stumps, the new grinder is built to power through tough materials with less operator interaction.

Features and Benefits
- The Series III hard-faced duplex drum offers durability and convenient maintenance, with the ability to remove and replace single hammers and balance the drum externally.
- Low side walls aid in feeding whole trees and other larger material with less restriction, reducing the need for operator interaction with the material.
- The SmartFeed system monitors engine rpm and adjusts grinding speed for optimal machine performance.
- The optional Damage Defense system reduces the likelihood of certain metal contaminants from entering the hammermill by reacting to the initial contact with the contaminant and reversing the feed system to allow removal of the contaminant.
- The feed roller can climb up to 50” (127 cm), helping the machine to crush logs or stumps that need to be rolled, and allowing the operator flexibility for different material inputs.
- Change screens easily utilizing the optional screen hoist and the remote control or main machine controls.
