Fast and efficient grinding of all the branches of trees, the Turbo-Cut Turbine better walking on hard, dry wood (drying approx 2 weeks), the foliage and the green branches as it works, but it is slower and are more frequent cleanings. No problems with the diameters (up to 42 mm) which fall into the machine. There will be appreciated the most barns and wheels wider apart for the land of the garden, but it does not move the machine frequently. Noise quite limited compared to models with the cutting deck. Very good buy, no regrets.
