Stump Grinders

With quality construction, operator safety features and a user-friendly design, Dosko's walk behind stump grinders are made to meet your tree care needs. Narrow widths ensure transport ease and a unique side discharge frame keeps cuttings away from the machine while grinding. Our stump grinder line-up features units that can be hauled in a vehicle, towed behind a vehicle or self-propelled onto a trailer or truck bed. With all this and more we’re convinced you’ll find Dosko® stump grinders to be the fastest, easiest to use units on the market today.
