What applications are Morbark tub grinders used in?

Morbark tub grinders are designed for the most challenging recycling applications. They excel at processing yard waste, pallets and other mixed woody feedstocks into saleable products. They can be used for processing whole trees, stumps, brush, construction and demolition debris, wood waste, and green waste.

What features are included on Morbark tub grinders?

Morbark tub grinders are equipped with hydraulic augers that allow the operator to quickly remove product beneath the mill, a full breakaway torque limiter system to protect the engine and clutch, a laser-cut, factory-balanced mill, and more.

What is the difference between tub grinders and horizontal grinders?

Both Morbark horizontal and tub grinders excel at processing wood waste into saleable products. Choosing between a horizontal grinder and a tub grinder depends on your specific needs, including the types of materials you need to process, desired output size and consistency, mobility requirements, space availability, and budget considerations. Horizontal grinders allow for continuous feeding of long and straight material, while tub grinders are ideal at processing bulky and irregularly shaped materials like whole trees, stumps, brush, and demolition debris.

What is the benefit of the externally adjustable break-away torque limiter?

For over a decade, Morbark's exclusive, Break-away Torque Limiter, has proven to be the industry's best solution for protecting the driveline of a horizontal or tub grinder from catastrophic failure. It reacts in milliseconds to a direct hit. No other system has this response time, which ultimately will save you downtime and money. The system is a standard feature on most current models of Morbark Wood Hog Horizontal Grinders and Tub Grinders.

What safety features are included in Morbark tub grinders?

Safety features may include emergency stop buttons, safety guards and shields, remote control operation, automatic shutdown systems, and hydraulic tilt tub for easy maintenance and inspection. These features help protect operators and ensure safe operation.
