About brand
Dosko has been around since 1983, starting out in southern California and building a reputation for making tough, no-nonsense stump grinding equipment. In 2010, Great Northern Equipment (GNE) took over ownership and continued that same focus on quality and practical design.
Every machine is designed, manufactured, and assembled in the USA, powered by Honda GX engines, and fitted with Greenteeth cutter teeth — components chosen for durability and long-term performance rather than just cutting costs. The lineup stays intentionally small, covering stump grinders and brush chippers, because the focus has always been on doing a few things really well rather than spreading thin across dozens of average products.
Whether it’s a rental yard, a landscaping crew, or a property owner dealing with a yard full of stumps, Dosko machines are sized and designed to get the job done without needing heavy equipment or a large team to operate them.

What peoples say
Real users — from first-timers to seasoned professionals — consistently point to how well-built, easy to operate, and dependable these machines are, even on the toughest stumps.
Linda Carmichael
Customer
I had three large oak stumps taking up half my backyard and the Dosko chewed through all of them in a single afternoon — compact enough to fit through my side gate but powerful enough to handle every root in the way. First-time user, zero issues, and I’d recommend it to anyone without hesitation.
James Hargrove
Customer
I’ve been in landscaping for over 15 years and the Dosko is hands down one of the most reliable pieces of equipment I’ve put on a job site — starts every time, handles big stumps without breaking a sweat, and easy enough for any member of my crew to operate.
Tom Bridwell
Customer
Bought the Dosko after renting different machines for years and wishing I’d made the switch sooner — it fits through tight spots my old rental never could, runs clean on every pull, and after two full seasons of heavy use it still performs like the first day I took it out.
