Weed eater is an essential gardening tool, drastically reducing the drudgery associated with trimming our lawns. These weed eaters come in various types and sizes, and the 2 main types are: the 4-cycle Weed eaters and the 2-cycle?
The 2-cycle and 4-cycle weed eaters are excellent at trimming grasses, but they have differences that endear them to their user’s hearts.
The 2-cycle weed eaters are powerful, even though they are lightweight and noisier. The 4-cycle weed eaters, on the other hand, are quieter and more expensive.
If you are wondering which of the 2 weed eaters is good for you, then come along as we discover all there is to know about 2-cycle and 4-cycle weed eaters.
What Exactly Are Engine Cycle?
It is almost cliche to about 2-cycle and 4-cycle, while in the real sense, it is a lot of science that we will try to simplify. When we say engine cycles, we are referring to the process of converting heat to work.
An engine’s cycle starts when it receives fuel which it burns in the combustion chamber. This burning of fuel brings about the generation of power, and the relieving of exhaust gases brings one engine cycle to an end.
The number of movements that a piston goes through to complete 1 cycle is called strokes. Hence, a 2-stroke engine, also known as a 2-cycle engine, produces mechanical power on its second stroke.
For the first cycle, the spark plugs cause ignition, thereby causing the combustion of compressed fuel and air. It can be said that a 2-cycle weed eater has 2 strokes, which are the up and down strokes.
Because of this engine’s simple operation and less moving parts, the weed eater is light and does not tire the hands easily.
The first stroke of a 4-cycle weed eater with a 4-stroke engine starts when the valve opens, the piston moves down, and a mixture of air and gas comes in.
When the piston has reached its lowest point, and then the crankshaft pushes it up, compressing the air and gas, that is the second stroke. With the gas compressed, the valve closes.
When the piston has reached the top, the spark plugs ignite the fuel and air mixture, thus creating power that pushes the piston down again, which is the 3rd stroke.
The 4th and final stroke is reached when the crankshaft pushes up the piston, which causes the exhaust valve to open, forcing the gas to go out.
Is a 4-cycle Weed Eater Better Than a 2-cycle?
There are lots of similarities and differences between the 4-cycle Weed Eater and a 2-cycle, and the question of which is better than the other depends on individual preference. Below, we are going to x-ray the different qualities that distinguish one weed eater from the other:
Because of the amount of work that it takes a 4-cycle weed eater to generate power, it requires that the material used in making them is very sturdy to withstand the stress; hence these weed eaters are more durable than the 2-cycle weed eater, which weigh less and easily breakdown on prolonged use.
2. Engine And The Power Output
The engine of a 4-cycle weed eater generates power on the 4th stroke while that of a 2-cycle weed eater does so on the 2 strokes; this automatically means that the latter generates more power per time than the former. Find out why your Echo Weed Eater Won’t Start.
3. Fuel Economy
The 4-cycle weed eater has a better fuel economy than the 2-cycle weed eater, and this is because the 4-cycle unit burns gas cleaner and the exhaust gas goes away on an independent step, unlike in the 2-cycle weed eater in which the exhaust gas does not get completely removed, and this means that the gas does not burn efficiently.
4. Weight And Size
Even though the 2-cycle and 4-cycle weed eaters are all heavy, the 2-cycle weed eater is less heavy than the 4-cycle unit. The implication is that the reduced weight gives them more cutting experience and power.
It is very obvious that the 2-cycle weed is cheaper than the 4-cycle counterpart, and this is so because its engine and operation are simpler, unlike what you have in the 4-cycle weed eater, which is a complex engine with more parts and more costly.
6. Noise Levels
The fact that 4-cycle weed eaters have a dedicated 3rd cycle for ignition and combustion means they are much quieter than you should expect. Secondly, the exhaust gases they emit are released in the 4th stroke, making it even less noisy.
These features are not found in the 2-cycle weed eater, which is why they produce more noise. A 2-cycle weed eater can produce a sound of more than 90dB, so you should protect your ear from such sound when using the device.
7. Pollution Levels
Even though both the 2-cycle and the 4-cycle weed eater pollute the environment because they use gas that emits greenhouse gases into the atmosphere, the 4-cycle weed eater produces less pollutants because of the stages it goes through to produce power, which makes it more Eco-friendly.
From our analysis below, you can see that each of them has unique selling points and downsides. So it is up to you to choose based on what you consider a priority.
So if you want a lightweight weed eater that is cheaper and produces more power, you should go for a 2-cycle weed eater.
If, however, you are concerned about the amount of pollutants and noise you will release into the atmosphere and want a unit that does not consume too much gas, then the 4-cycle weed eater is for you.
Similarities Between the 4-Cycle And 2-Cycle Weed Eaters
There are many similarities between the 4-Cycle and the 2-Cycle weed eater, especially in terms of function. They are both used for cutting weeds and grasses and are powerful tools that make trimming your lawn look like a walk in the park.
The 2-cycle and 4-cycle weed eaters require proper maintenance; hence you should adhere to the prescribed maintenance regime.
For the 2-cycle weed eater, you must maintain a certain oil and gas ratio if they function properly, whereas you have to be careful with storing the 4- cycle weed eater.
Most 2-cycle and 4-cycle weed eaters have the same tube length, even though there are versions with shorter tubes meant mostly for women.
Almost all weed eaters have the same cutting width range, usually from 17 to 18 inches; this is the case with even electric weed eaters. There are just a few models that have variations in their cutting width.
