Lawn mowers and lawn tractors employ revolving blades to be able to horizontally cut the grass measuring uniform above the ground level all through a backyard or a yard in its whole area. There are 2 kinds of blades that these machines employ. The first are the rotary mowers through which the blade structure revolves around a standing axis; and the second form are often known as reel mowers which make use of a blade structure revolving round a lying axis. The basic and the smallest in size of either of these mowers are called push mowers as theyre pushed from behind in order for them to do the job.
There are a few things however that you want to consider such as the proper maintenance of the mower itself. Always make sure to keep your mower clean and free of excess grass clippings and dirt. Also make sure that oil changes and spark plug changes are done at recommended intervals. You will also want to make sure to keep your blades in shape with regular blade sharpening. A sharp blade will make for better cutting thus reducing how hard the mower will have to work. The second option with Push Lawn Mowers is the self-propelled mower. These mowers make walk behind mowing a little easier to deal with.
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.
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.
