What is a Gas Lawn Mower
Each house owner wants to have a good-looking lawn in his/her yard. A lawn mower is ready to help. Some models are designed to trim grass, while others are able to fertilize ground as well. Gas lawn mowers with internal combustion engines refer to such models. They are notable for self-sufficiency and wide working range: they don't need a connection to power supply, and their power is enough to process big areas. Thus, they have gained wide popularity and become irreplaceable assistants in gardening.
What Features to Compare
The performance of gas lawn mowers depends on the engine power. The more powerful engine is, the faster the blades rotate, drawing the mown grass. You should make your choice based on the area of your yard. For example, a model with the engine up to 2kW is enough for a lawn of up to 1/7 acre. If you have a yard of 1/4-1/3 acre, you will need a lawn mower with the power up to 2.5kW. Lastly, if you possess a lawn of 1/3-1/2 acre, you should pay attention to the models of 3kW and more.
The efficiency of mowing is influenced by several parameters such as a number of blades, width, and cutting height. A gas lawn mower usually features two blades, but there are models with one dual blade. Such a design is needed for fine grinding that is also called mulching. If we consider the cutting width, most lawn mowers have cutting decks from 13” to 17”, while professional models feature the cutting path from 17” to 21.5”. The wider the blade is, the more grass it can grab per a single sweep. Concerning the cutting height, it can be also adjusted from 1.2” to 4”. Every lawn mower features several cutting modes: mulching, bagging, and discharge. Bagging and discharge are clear, yet mulching should be more to tell about. Mulching means the grinding of grass until a formation of mulch to be dropped on the ground. In such a way, mulch forms a special layer that protects the lawn from vermin, weeds, retaining the damp. The mulch decomposes and, thereby, serves as organic fertilizer for the ground.
There is no doubt that a lawn mower should be powerful and efficient, however, it should be usable as well. The drive wheels are the main peculiarity in this regard. When a lawn mower propels itself and you just guide it in a needed direction, it is easy and nice to use, in particular if the ground is hilly. On the other hand, if you have a lot of trees or sharp turns in your yard, it is better to use a non-self-propelled model. The usability may also include the availability of a bag or a catcher for grass collection since some models come without this equipment and you need to pick grass by yourself. The size also plays quite an important role. Some lawn mowers are equipped with folding handles providing convenience in storage. And, of course, you should pay attention to the engine. The engines of all gas lawn mowers are the same in maintenance; they should be washed, and oil should be replaced each 50 hours. But, the advantage is apparent – the mower does not depend on a power supply and the working range is unlimited. Sums it up!
