Essential Lawn Mower Parts

The 21st Century has brought automation on most of the things we use in all of our daily activities. We come to expect that all the gadgets work as they should and are oblivious to them as long as they work perfectly. It happens with our car, our televisions, media players, computers and even lawn mower parts. We do not really care how they work or what they are made of, until they start acting up strangely or completely break down. When they do, then its only the time we start to wonder what went wrong.

The great thing about knowing the lawn mower parts is that you have an easy time diagnosing the problem when something goes wrong. It will save you time, money and effort in the required maintenance and repair when needed.

Essential Lawn Mower Parts


Here are the basic lawn mower parts:

1.      Housing and Wheels – The chassis, housing, or framework of a modern lawn mower is typically comprised of steel, though many supporting lawn mower parts are forms of resin-based plastics with heat and vibration resistant properties.  The mower housing rests atop some form of axle-connected wheels, safely covering all the moving lawn mower parts which protects the lawn mower engine

2.     Carburetor – This is an essential part of a petrol lawn mower. It is part of an internal combustion engine that mixes air and fuel.  The carburetor is a mixer of sorts, regulating the amount of fuel and air delivered to the combustion chamber for ignition by the spark plug.

3.     Air Filter – Protects the engine’s internal components from dirt and debris. Yes, the lawn mower engine will operate without an air cleaner, but it won’t be long before dust and other contaminants will cause the internal components to breakdown. Additionally, the air cleaner keeps trash out of the carburetor, allowing the gasoline and air to flow without obstruction.

4.     Spark Plug – A spark is necessary to ignite the fuel-air mixture in the combustion chamber. An electrical current supplies power to the plug to generate a spark when the engine’s piston is near the top of its stroke. As the fuel-air mixture “explodes” as a result of the spark, the piston is forced back downward in the engine causing the crankshaft to turn. The rotation of the crankshaft sends the piston back up the engine’s cylinder where the whole ignition process is repeated over and over for as long as the engine is running.

5.     Lubrication System – Every time the engine is running, the internal components of a lawn mower generate a tremendous amount of friction that produces heat that quickly spreads throughout the engine. The high temperature causes moving components to expand creating even more friction. The cycle would continue until the engine seizes up and gets ruined. The lubrication system within the engine keeps things cooled down and well-oiled to prevent such a catastrophe.

6.     The Blades or Cutting Implements – In the case of the old-fashioned mowers known as reel mowers, the blades were multiple and curved (slightly twisted) and spun around on the same horizontal axis as the axle to which they were affixed. Modern rotary blades are sharp-edged blades, usually numbering two, that spin on a vertical axis at a high velocity enough to easily cut through grass at a much faster rate as well as being able to handle taller, wetter and thicker grass than the conventional reel mowers can manage. There are also complex blade arrangements known as multiple blade or gang mowers designed to be pulled by full-blown tractors but these are not typically used on lawns but are more suited for large commercial cutting jobs.

There are additional lawn mower parts that might relate to optional features like speed controls, height adjustments, discharge bag attachments and even connections or holding brackets for personal operator devices such as beverage containers or electronic devices but which can be dispensed with without compromising the normal operation of the equipment.
