I have a garden of 2600 m2, so lots of waste cuts. I bought the mill with a very positive evaluation of the "Stiftung Warentest" (German foundation to test products). According to the documentation the machine grinds up to 250 kg of branches per hour - I gave up after only 20 kg ... If the branches are not straight, if any leaves, if the timber and too hard or too loose (eg reeds) the device will crash or mouth right away. The twisted branches are not drawn. I tried with branches of laurel, boxwood and reeds - each of these greens the device could not be crushed.
