If youve ever wondered how petrol lawn mowers work then youre not alone. Hopefully this small guide will help you on your way. The principles behind how a petrol lawn mower works versus an electrical lawn mower are pretty much identical. The main difference of course is the source of the power that spins the cutting blades and in some case the rear wheels and / or rear roller. A petrol lawn mower comes supplied with in most cases a 4 stroke engine which generate between 3 and 6 horse power. Being 4 stroke means the mower can use standard unleaded petrol that you can buy from your local petrol station.
Some basics regarding riding lawn mowers: Mowers are available in a lot of variety size and price ranges. However before purchasing it youll need to conduct some careful research on it.

The recall involved 20- 21- and 22-inch walk-behind lawn mowers and some 30-inch mid-engine riding lawn mowers. 38- 40- 42- and 46-inch lawn tractors 46-inch garden tractors were also recalled by the company. The problem was related to the plastic components of the lawn mowers that cracked when struck by the objects thrown by the blade. These parts could be ejected from the lawn mower completely unexpectedly and the nearby consumer could be injured. As of now no complaints have been received by the commission regarding the injury but the recall was initiated all the same to avoid possible injuries.
The combustion within the engine then powers the cutting blades of the mower which can either be rotary or cylindrical. The rotary blade acts like the big hand on a horizontal clock. They rotate clockwise cutting the grass as they turn. In most case there are 4 blades and they are shaped to produce an updraft of air as they spin like an aircraft propeller. This causes a differential in pressure under the mower which pulls at the grass before cutting it. The rotating blade mower works much like youll see on a combined harvester. One blade will capture and lift the grass and then the next blade in the cylinder will cut it.
