The big question: knife or roller? I do not know how 50% of all users. The advantages and disadvantages can be researching in several articles and you're behind just as smart as before. I opted for the roller and that the Atika. The offer I slammed and obviously tried long. Our new garden, we changed clothes, are some rhododendrons. This had to give and where to put all the branches? So off to the shredder. I started with small branches and zoom worked my way slowly to the Recommended thickness. No problem. After the third day I had my first breaker. The brave fellow had all retired without grumbling, of course, there was in the bay storage times, but the engine ran on and on. By the time I did not pay attention to the thickness of the branches and suddenly the engine was off. So pressed the reverse button. Everything is all right again! Actually I wanted to branch then remove, but on the second attempt, the guy has, although with difficulty, crushed it into small parts. The estate is the size of small MundM comparing's. Also, one should not really, I have chopped complete branches with leaves on it. The leaves are but two, up severed three times. Since we do not want to mulch, we did not care. The stack branches, we got packed in handy garden tons. The brave guy will be called in the spring to new tasks, as is still 2/3 of the bushes, all have to give way. I'm sure he'll do it without complaint!
