A 41cm cutting width means that with one battery you should be able to cover about 300m2, (thats about 17m x 17m), and can go as much as 600M2 (25m x 25m) using the 4.0ah (2 x 2ah Batteries) . The height is adjusted by an innovative push button system, its spring loaded so is really easy to use. The 40v 41cm Lawn Mower can be set at 5 heights through 25mm to 80mm (1 inch to just over 3?). Its also really easy to store and transport as it has folding handles which mean you can pack it down into a small space. A large 55Ltr collection bag means fewer trips to the compost heap, or alternatively you can take advantage of the mulching feature on the mower, which cuts the clippings ultra fine and puts them back into the lawn as a feed.
