KAkizukiG 1 I bought this mower in an attempt to be reasonably considerate of the environment and noise to others. Even if more expensive than a motor driven one. It is light weight and easy to use BUT USELESS AS A MOWER FOR JAPANESE GRASS LAWNS. The so-called heavy duty battery, fully charged, lasts less than 40 meters, (see photo) even with with the height setting at the mid level. Just 75 seconds of operation on the thick Japan-style lawn grass. This is totally unacceptable and Makita has falsely promoted this product. If I could return the product I would but as I bought it during the winter in anticipation of use in the summer it is too late. My recommendation: DO NOT BUY THIS MACHINE.
