Dosko 691SP-HE20 Stump Grinder

Overall, I'm very pleased with the unit. It is clearly a very high quality unit. Final Assembly after I received was straightforward with the instructions provided. I was able to use the machine once before snow and it performs exceptionally. I would have rated it 5 stars but I was contacted by Northern Tool and informed that it requires service due to concerns with improper assembly. They sent the instructions and it looks to be straightforward although I had to buy a tool I didn't have to comply with the instructions. This was disappointing but I'm thankful they notified me so I can take care of it before anything breaks.
