So the equipment really excited! Have one day 9 trees apportioned (between 10 and 30cm in diameter). The decisive factor is, of course, the lever which is used). Here it must be ensured that this is as high as possible. I have the ratchet set at the bottom of the tree and the neighboring flat to legends tree usually appended at 1,5-1,8m. What I really like is the quality of the product is never the fear that one that flies around your ears, The problem I had with another product and since I am very careful ... Whether you're exercising really 4t force the issue .. I have given all the levers, but a tree (40cm) still stands because I probably only have a go at the roots;) But in any case one can with full Balancing reinhängen, without being dangerous. Just buy it !! The only downside is the poor operating instructions and that are possible with 4t traction only 1.5m way. PS: please buy appropriate slings so you nothing flying around your ears!
