In-depth Differences Between Liquid And Air Cooled Lawn Mower

It is crucial to learn some important details about both lawnmowers as they vary from each other in different aspects. Check out their main differences.
- Manufacturing Approach
It is important to get into how a machine is designed and manufactured. Compared to air Cooled Lawn Mower, liquid Cooled Lawnmowers are trickier to manufacture due to their distinctive design.

- Efficiency
Machine efficiency is important when you want to get the best result. Though both types of machines can show reliable performance, liquid-cooled lawn mowers.
The reason is that the water version can hold its HP better even while operating in too hot weather. On the contrary, an air-cooled lawnmower may have reduced efficiency during excessive heat since all moving parts become highly hot.
- Durability

Since most of us buy lawnmowers for a long-term investment, we want them to last the longest time.
Unfortunately, a lawnmower has a limited lifespan regardless of the mower you choose.

On the other hand, a Liquid Cooled Lawnmower will last approximately 10-15 years if you do the maintenance and cleaning tasks appropriately after every use.
- Temperature Regulation
Like other machines, lawnmowers have a particular heat tolerance level. When it becomes excessive, it affects all the moving parts, causing its performance to slow down.
Compared to air-cooled lawn mowers, liquid-cooled lawn mowers are better since they can better regulate the temperature.
This will uplift the performance of the water-cooled engine by ensuring proper power and perfect fuel economy.
- Maintenance
As a conscious gardener, you want to take care of your lawnmower regularly. It will improve its performance and keep various parts in good condition.
Liquid Cooled Lawn Mowers require a little more maintenance than an air-cooled lawn mowers. For example, it is crucial to keep the radiator clean to prevent poor coolant circulation and overheating issues.
However, regular maintenance is always necessary for types of lawn mowers. To prepare for the winter offseason, it is a good rule of thumb to properly clean and lubricate different important moving parts during the summer and spring.
- Noise
Generally, a lawnmower produces 90 dB to 110 dB sound. But most modern lawnmowers make a healthy noise level to ensure convenient operation use them.
Compared to an air-cooled lawn mower, a liquid-cooled lawnmower creates less noise because the engine supplies water to the block and head that prevent moving parts from being closer to each other.
- Liquid Cooled Lawn Mower

How much money are you ready to pay to own a lawn mower? The average lawn mower price can be anywhere from $200 to $2000.
Rear engine type lower mowers are highly expensive, while electric push mowers are incredibly inexpensive.
If you are looking at a mid-range option, Gas Self Propelled is worth considering.

For instance, The Honda Lawnmower Tractor 4514 Hydrostatic 2 cyl Liquid Cooled has a price of $850.
In contrast, air-cooled lawn mowers are pretty affordable. For example, the KOSHIN EBC-35C hand-push lawnmower price is around $350.
- Availability
If you can’t purchase your preferred lawnmower from your nearby shop, it is a few hassles. After all, you don’t want to spend additional time and money to purchase it from a distant place.
