Good alternative to electric or gas mower

We have built new and on our property there is an approximately 30 square meters and 5 square meters large lawn. This small area is on top of that can only be reached via steps. As asked myself what I take to mow. The answer was found quickly. The cylinder mower is really good for not too large lawns, it is easy, therefore the stairs are not a real obstacle more and he mows all very well, but sometimes you need a second time nachmähen when the grass is too high. Continuously to adjust and quiet it is. So even on Sundays and holidays can be mowed. One should, however, only mow the grass when it is really dry, everything else will stick to the mower, especially the bearing between cutting edge and the outer casing is wrapped tightly the grass. You have to pretty rumpfliemeln to get everything clean again. Do not use water (garden hose) clean, but clean them dry and now and then a little oil / WD 40 etc. enter the cut, then the mower should remain sharp for a long. So far the best alternative for our little land as easily, saving space accommodate and sharp edges.
