|Started in 1983, Dosko are an American manufacturer of chippers, stump grinders and mulchers. Their machines are designed to be portable but durable. They are now based in Rogers, Minnesota and have dealers|| in the US, Canada and New Zealand.
Their stump grinders utilise a front-mounted cutting wheel for increased safety and a handlebar adjustment system with five positions for different users.
| chippers have an in-built "Smart Feed" program to measure the RPM and use that reading to change the roller speed, with the result that jams are reduced and the chipper is more productive.
