Hello. Since there are many screwdrivers here, I hope for experience with lawnmowers, after all, the main part of the lawnmower is the engine For my mother-in-law we are looking for a new lawnmower for 400m2 lawn in the garden. At the moment the 40-year-old Viking lawnmower is finished, it starts badly, every third time I can press, when it is drunk off, or the rope has tangled up somewhere, as it always does. False air, the gasifier is leaking etc. Actually it is still running, but it is not so unfriendly and is operated by amateurs. However, it does not have a wheel drive, which is now desired. Is the battery technology already so far, or is a burner still the right one here? The area has many trees and hedges, so that you can not start from the optimal running time because of the running time of a battery-mower, since you often have to rank. You should already be able to mow everything. without reloading or a second set of batteries. The question is also whether we take a cheap part from the hardware store and replace it after a few years, if it weakens or annoys, or take a brand mower, there are parts and also dealers who may know each other, in the hardware store this is rather not the case. Maybe you have experiences that you could call me here, manufacturers are good etc. Thank you very much Jack
