628 Debarker

The Morbark 628 Debarker was developed to debark logs from 6" to 28" (15.24 cm - 71.12 cm) in diameter. Using the patented Morbark Debarking Principle, the 628 features a floating cutterhead and variable speed feed rate that removes not only bark, but also nubs and knots from hardwood and softwood. The 628, like other models, also will debark stringy-barked species, such as cedar and cypress, with ease. Frozen or dirty logs are effectively debarked by the 628, making it ideal in northern climates and other less-than-ideal conditions.
