Types of Lawn Mowers

Lawn mowers can be categorized in several different manners as per the need of the user, but the most apt and desirable way to do that is to categorized using energy source. When sub-dividing lawn mowers as per their energy source, three major configurations result. These configurations provide a holistic view about lawn mowers and are all encompassing, providing a detailed insight of what every lawn mower is like and what could be the most suitable for an application.

Hand powered Lawn Mowers  (Push Lawn Mowers)

Hand powered lawn mowers mark the first and the oldest category of lawn mowers since the inception of the machine. Being the earliest and the first of its kind, hand powered lawn mowers have limited applications and do not provide extreme precision. Despite their drawbacks and shortcomings, hand powered lawn mowers still make up the majority of the sales for domestic users.

Being simplistic in operation, cost effective and good worth for domestic customers, hand powered lawn mowers find most of their use in backyard lawn. People who would not spend large sums and do not want perfection when trimming grass opt for this kind. It provides the desired results, is effective and cheap and can last a long time. This is the prime reason why despite the advancement in technology, these hand powered lawn mowers still have a considerable share in the lawn mowers market.

Gasoline Lawn Mowers

The first major advancement in the lawn mowers came with the inception of the gasoline powered lawn mowers which were designed for better precision, more comfort and require more resources to operate. Gasoline powered lawn mowers are operated through rotary push mowers which operate through internal combustion engines. The traditional motors used two stroke engines which provided a decent amount of torque and good output for mowing.

With the passage of time and with increasing use of technology, four stroke combustion engines became a norm for the gasoline powered lawn mowers. The four stroke engines provided more torque and a far better output as compared to their predecessors and became popular for applications where precision and comfort were desired over cost.

The internal combustion engines which are used in the lawn mowers tend to have a single cylinder. The single cylinder is able to provide a power in the range of 1 to 7 kW, an amount that is sufficient for domestic as well as commercial use. Traditional gasoline powered lawn mowers had to be started using a manual pull crank and came with a carburetor.

Advanced gasoline powered lawn mowers do not require a manual pull crank and are started through an electric power starter. Such lawn mowers come with various other options such as a handle bar to vary and control the speed of the lawn mower, select the desired trimming and many more. The throttle bar is not common to every gasoline powered lawn mower, and is an add-on which comes in at a higher cost.

The major advantage of the gasoline powered lawn mower over the hand powered lies in comfort, precision and the level of control that can be obtained. Another major advantage is the output torque that is generated through a gasoline powered lawn mower, which is far greater than its predecessor.

Electric Lawn Mowers

Probably the most popular and the best of their kind among lawn mowers are the electric lawn mowers. These lawn mowers are the most advanced machines and come in two major types; corded and cordless. Electric lawn mowers are silent machines, producing very little noise and are extremely smooth to operate, provide excellent precision and come with various controls for the lawn mower.

The two types of electric motors are described below:

  • Corded: Corded electric lawn mowers are attached to a cord which is connected to a power supply. The lawn mower is powered through the cord and hence has a range to which it can operate, depending on the length of the cord. Corded electric motors were the first type of electric lawn mowers, but have some serious drawbacks.
  • Corded electric lawn mowers have a risk of mowing over the power cable itself which would switch off the supply and stop the mowing process. The machine can also lead to electrocution during damp seasons and hence poses some severe risks. The functionality is also limited to a small range and hence corded lawn mowers are not used in large organizations or in professional applications.
  • Cordless: Cordless electric lawn mowers are a more advanced electric machine version of lawn mowers which eliminate the drawbacks faced from the corded machines. The cordless lawn mowers are usually powered by 1- 4 rechargeable batteries, each of 12V. For a larger application, more batteries can be used which would increase the run time of the motor. Corded lawn mowers are extremely precise, environmentally friendly and are very easy to operate. They combine the best features of all the previous versions of the lawn mowers and have excellent control variation for the users.

They are adaptable to change and are rechargeable which is convenient for continuous application. One drawback though, of the cordless electric lawn mowers is that they are more expensive and do not provide the same level of torque as by those of the gasoline lawn mowers. Batteries have limited capability and more of them would be required to match the output torque to that of the gasoline lawn mowers.


Things to Consider before Buying a Lawn Mower

Additionally, it is a matter of cost

For domestic users, low on budget and wanting a simple grass leveler, the hand held or the gasoline lawn mower would do just fine. It the lawn is quite big, a gasoline lawn mower would be preferable as it will be comfortable and less tiring to mow the lawn every once a week. Both these kinds of lawn mowers are cost effective and will be durable. It will be a better investment that will last long and hence will be ideal for people not wanting to spend much.

For commercial users and large organizations, cost is not an issue. The prime concern is the level of detail, perfection in ambience and the environmental factors such as noise and pollution. Environmentally friendly organizations would certainly opt for cordless electric lawn mowers since they provide the best operation without making much noise and pollution. Electric lawn mowers also have fine detail characteristics which enable the user to mow the lawn in the most intricate manner possible. Ambience and aesthetic appeal are of prime concern and electric lawn mowers can cater to such needs without much ado.

A few words on Batteries

Electric lawn mowers may not last very long for batteries tend to run out. Either the batteries can be replaced or the machine may at times need to be replaced, but for organizations, electric lawn mowers are a far better option.

The main elements in deciding the right kind of lawn mower are hence the kind of operation requirements, costs, environmental factors and durability. Due consideration to these factors can make the decision a very simple one in the end.


FAQs – Frequently Asked Questions of How to Use Lawn Mowers?

Let’s now look at the usual questions that people have regarding lawn mowers and the correct and precise answers to them. Of course, all of the questions may not be answered here, but it will provide sufficient help to people who need it.

Q1. When do I change lawn mower oil?

Ans: Remember, engine oil needs to be replaced after a specific period of time for long lasting service. Generally, that time is up to 50 hours of use. After that, one needs to clean the filter and change the oil with new one. Continuous operation of the lawn mower without replacement of oil will damage the equipment and reduce its life and efficiency.

Q2. What is the best fuel type for lawn mowers?

Ans: Clean, fresh and unleaded fuel is most desirable for lawn mowers for greater efficiency and better performance. Gasoline with up to 10% ethanol (gasohol) or up to 15% MTBE (methyl tertiary butyl ether), is acceptable for lawn mowers.A canned fuel product can also be used. This fuel combines ethanol-free unleaded gasoline with a fuel stabilizer to prolong the life of the fuel.

Q3. Do I need to check and clean the spark plug?

Ans: Spark plug provides the ignition for the lawn mower to start. A clean, lubricated spark plug will provide the perfect ignition for smooth starting of the lawn mower. As the spark plug wears during operation and dirt accumulates on it, it requires a higher voltage to ignite the lawn mower which can be damaging for the machine.
To safely clean a spark plug, a brush or a spray-on plug cleaner can be utilized. For the tough deposits of dirt and oil on the spark plug, a sharp knife can be used for the purpose of cleaning. It must be ensured that the spark plug is not damaged in the process.

Q4. Why do I need to clean the carburetor?

Ans: During mowing, twigs, grass and other dirt particles tend to get inside the carburetor and block it from the inside. These particles clog the air and fuel passages which limit the operation of the lawn mower and hence it is imperative to continuously clean the carburetor after a month or so of operation. A clean carburetor will increase the performance and will require less effort to mow the lawn.

Q5.Do I need to replace my brakes for the lawn mower?

Ans: In most lawn mowers, a well-maintained brake system should stop the engine and any attached cutting equipment within three seconds whenever you step away from the equipment or release the brake bail. If the engine operates for more than three seconds after braking, then the stop switch or brake pad may be in need of replacement or adjustment.Replacing the brakes immediately is imperative as it will avoid any problems or injuries during the use of the lawn mower.



Tips for using Lawn Mowers

  • Fuel Storage tip:

Gas will become stale if you are storing your lawn mower or power equipment for more than 30 days. Stale fuel can cause engine damage from acid and gum deposits forming in the fuel system or carburetor. Damage to the carburetor or engine due to bad fuel will void the engine warranty. Keep lawn mower gas fresh by using stabilizers designed for such engines.

  • Spark Plug:

For consistent, easy starting, change your spark plug every 100 hours or every season. This has three major benefits:

  • Improves fuel economy
  • Reliable and smooth starting of the lawn mower
  • Consistent sparking which does not damage the engine

  • Engine Maintenance:

For optimum performance, you should change the oil in your small engine after the first five hours of use and then annually, or every 50 hours of use. This will keep the engine clean, regulated and will avoid any deposition of dirt and filth inside. New oil also ensures smooth and effective running of the lawn mower and enhances the life span of the machine.
