Introduction
A petrol cylinder lawnmower is the ideal mower for you if you want to achieve a finely cut lawn and can be seen being used by numerous groundskeepers maintaining lawn tennis courts and bowling green’s nationwide, hence why the petrol cylinder lawnmower is primarily known for producing a ‘Wimbledon’ style final cut.

Basic Specifications
Quite intriguingly, the basic design specification of the lawnmower is near identical to the specification of the original lawnmower that was invented in the early 19th century. More regarding this will be discussed in further detail down below.
Cutting Bar – The cutting bar can be set at a specific height for which the machines allow you to, but it’s important to note that each machine is likely to have a different range of possible set cutting heights.
Cylinder – A set of blades for which spin and push the grass past a cutting bar. This can be up to as many as 10 blades for push-type models.
Frame – Most models you will find will have a metal frame as this gives the best possible support while in use.
Handle – Again, these are attached to the frame of the lawnmower and will therefore enable you to push the machine across your lawn without any real difficulty.
Motor – The power source for the cylinder; petrol, feeds an internal combustion engine, which then sets the cylinder in motion to produce its quality cut.
Wheels – These are attached to the frame of the lawnmower usually.
Key Features
The key features of the cylinder within the lawnmower are the cassette and the cutting bar height adjustment mechanism.
Cassette
The cassette houses the cylinder and the axle around for which it spins. The number of blades on the cylinder affects how finely cut your lawn will be, hence as discussed above, the need to have as many as 10 blades on the lawnmower, to allow flexibility in your decision-making. Furthermore, the width of the cassette determines the size of lawn for which the mower is deemed appropriate, in terms of quality of the final cut. The general rule is the wider the cassette, the more efficiently it will cut lawns as they increase in size.
Cutting Bar Height Adjustment Mechanism
Most petrol cylinder lawnmowers will allow the user to adjust the cutting bar height. Having the ability to adjust the height is incredibly important because it will affect a mower’s versatility, so buyers who potentially want to purchase one will have to consider whether a variety of cutting needs is something they are likely to need when using one.
The key features of the engine itself are of course; its capacity and speed.
Capacity
The capacity of the engine is the amount of air the combustion cylinder pistons displace during the internal combustion process. Most petrol cylinder lawnmowers will consist of a four-stroke engine, meaning the engine operates in four steps. Firstly, each cylinder takes in air. Then, this is compressed, and the combustion process follows suit and finally results in the cylinder exhausting the air. The more cylinders the engine has, the higher its capacity will be and therefore the more power it will generate.
Speed
In addition to spinning the cylinder, the engine will also help propel the device in your intended direction you want it to move in. Some models will have an engine throttle that can allow you to control the speed yourself.
Some makes of the lawnmowers does have the bonus of having an attachment that will capture and store grass clippings as you are mowing the lawn. Obviously, this makes the clear-up process post cut easier and more efficient also.
Advantages and Disadvantages
One main benefit of a petrol cylinder lawnmower is that it probably provides one of the cleanest cuts out of all the lawnmowers available, making it a highly effective and efficient type in a variety of ways, including enabling blades of grass to heal quicker, making the lawn itself more resistant to weeds etc. Also, petrol will provide more power than electric lawnmowers and are also non-reliant on cords that will be required for most electric models out there.
However, a major downside to petrol is that the internal
combustion process will produce fumes, unlike electric. The lawnmower will also
need a significant amount of time and attention for it to be adhered to,
regarding changing the oil within the motor (needs to be done on a consistent
and regular basis) and replacing/fixing the spark plug if needs be.
