If you've ever pondered how petrol lawn mowers work, then you're not on your own. All being well this small guide will help you on your way.
The basics in the workings of how petrol powered mower work are very akin to how their electrically powered friends work. The petrol powered mower, however, has on board a motor that powers the rear wheels on a self-propelled mower and primarily, drives the cutting blades at the business end of the mower. As is the way of the world, though, the more you want the more it costs but if you do a bit of research before you can find many quality but inexpensive petrol lawnmower.
Quite a lot of petrol powered mowers, pretty much like the McCulloch M46-125, come with a 4 stroke engine that can produce up to 6 hp (and in some cases, more). It's a good thing that they do use this sort of engine as it means they use the identical gasoline you use to fill up your car! The combustion within the engine then powers the cutting blades of the lawnmower which can either be rotary or cylindrical.
A rotary blade is like a scythe on the bottom of the lawnmower. It rotates round cutting the lawn as it does. There are normally four cutting blades and they are shaped similar to a planes propeller so that they suck up air. This causes a change in pressure underneath the mower which pulls at the lawn before cutting it.
The cylinder bladed mower looks, underneath, like the wheel that you might buy for your domestic mouse albeit the blades are twisted and joined irregularly. The cylinder will turn over and over slicing at the blades of grass as it goes.
So, lets get down to how lawn mowers work :
By pulling what is known as a starter cord, the machinist will cause the engine to burst into life. You’ll have seen these many a time whether on leaf blowers or outboard motors. You may be blessed to come across a lawn mower with a starter key which is similar to how you start your auto before a journey.
The purpose of the engine is to provide the power required to drive upto two parts of your lawnmower dependent on the model you own and it's features. To begin with and vital of all, the motor will provide the power to rotate the blades of the lawnmower. If you have a model of mower that is billed as self-propelled - this means that the motor needs to power the rear wheels / roller so as to push the lawnmower frontward. Sadly, a self-propelled mower generally needs a bigger motor than one that is push powered which means, probably, a greater cost price.
The motor is usually operated by a throttle that you'll find on the the handles of the mower. The greater the pull on the throttle, the more petroleum the engine gets which increases the revolutions per minute (RPM). For the motor to do its work, the RPM needs to rise so that it makes more power.
As already said above, the rotating blade under the mower then captures the grass beneath either by suction or by a cylinder blade “grabbing” the grass and then the blade cuts at the chosen height. A small control is generally available which lets the worker to set a variety of different cutting heights on the petrol lawn mower. Cutting grass to different heights during the cutting season can contribute to the wellbeing of your lawn so paying careful attention to a petrol lawn mowers cutting heights is key.
The motor is powered up, the blades are cutting the grass - now we need to dispose of the grass cuttings in some way. As far as we're aware, all mowers come with a grass collection box of various sizes, but there a few different alternatives that some mowers offer. The collection box is connected to the mower and any lawn cuttings are stowed here until the container is emptied. On some brands and models, the grass container can be left off and the grass is discharged from the rear of the lawn mower and, sometimes, discharged from the side. Then there is mulching. The grass is cut into tiny clippings and then released back onto the lawn where they've just come from. Once they are deposited back on the lawn, micro-organisms will break them down further and reintroduce their nutrients back into the earth, fertilising it as it goes.
And so there you go. That’s how mowers work. There are a number of other details we could go into to, but as a rudimentary level, that's all you need to know.
