2025 Vermeer® Horizontal Grinders HG6800TX
For enhanced flexibility within a single machine, a dedicated chip drum, adjustable for product size ranging from .125 in - 1 in (.3 cm - 2.5 cm), is available.
The HG6800TX features low sidewalls to aid in feeding whole trees with minimal restriction, reducing the number of operator interactions with the material after loading and allowing the operator to focus on the next load.
The Series III hardfaced duplex drum offers durability and convenient maintenance, with the ability to remove and replace single hammers and balance the drum externally.
The SmartFeed system monitors engine rpm and adjusts grinding speed for optimal machine performance.
An industry-leading, full-function, wireless remote control lets you adjust machine settings from the cab as conditions change, including control of the infeed settings, engine droop, conveyor height and more.
Reduce the quantity and distance of thrown material debris with the Thrown Object Deflector (TOD), strategically placed to reduce interference when loading over-length material.
Features may include:
- A flagship horizontal grinder built to maximize productivity and efficiency
- Robust build quality for confident longevity
- Maintenance-friendly design optimizes serviceability
- Equipped with Vermeer innovations to help protect your investment and optimize efficiency
