A Rotary Lawn Mower which runs on petrol has many advantages over an electric rotary mower
. One of the main advantages is that it has much more power than the electric mower. Another benefit is that the blades of a rotary mower spin at high speed horizontally and they cut grass by tearing it. This way over grown grass can be easily managed and a deeper cut is possible and people would not need another cut for a long time whereas in electric mowers it is not the case and they cut grass more like cutting with scissors which requires frequent cutting.
