The Yardbeast 4521 Commercial Grade Wood Chipper is the ultimate solution for tree care companies and property owners with medium-sized parcels. It is designed to effortlessly handle branches and debris up to 4.5 inches in diameter and is powered by a robust Kohler CH640 Command Pro 20.5HP engine, ensuring top-notch long-term performance.
