Of all the brands that manufacture lawn mowers, Troy Bilt is one of the most common household names. A lawn mower looks like a simple, single unit. But trust me, there is more to it than meets the eye. The parts for Troy Bilt mower are quite much. Some can be seen easily, while some are in the engine compartment doing their job. You can only see these parts if you do a total overhaul of the system. So in this post, we want to consider the main parts of a Troy Bilt lawn mower.
Apart from the usual oil filter, fuel filter and air cleaner, there are other parts of the lawn mower that we would like to mention. Some of these parts are: piston, crankshaft, cylinder, flywheel, oil seal, fuel tank and flexible shaft. These parts are very important in the functions of a Troy bilt lawn mower. You usually will not see these parts talked about often, and that is why we will take the time out to highlight them this time.
TROY BILT LAWN MOWER PARTS AND THEIR FUNCTIONS
Below are parts that can be found in a Troy Bilt lawn mower:
Air cleaner
This is a very important part for Troy Bilt lawn mowers. The air that enters the carburetor for combustion could have dirt particles from the surrounding, or debris from continuous mowing if it does not pass through the air cleaner.
The air cleaner filters the air and makes sure it not contaminated.
Oil filter
Just like the air cleaner, the oil filter is also a very essential Troy Bilt mower part. It makes sure that the oil that enters the engine part is free from dirt and debris, so that it will not cause damage to the moving parts.
Carburetor
Troy Bilt lawn mower carburetors are of two types: a standard carburetor, and a semi-injection carburetor that has a pump that sprays fuel into the combustion chamber.
No matter the type, a carburetor supplies fuel to the combustion chamber of the lawn mower.
Recoil starter
This is the part that gets dragged when you want to turn on a Troy Bilt lawn mower. It has a recoil, meaning it will get back to its original position after you have pulled it.
Ignition system
Now not all Troy Bilt lawn mowers have a recoil starter. Some can be turned on using an ignition system. This ignition system consists mainly of two parts, which are: Capacitor Discharge Ignition (CDI) and a spark plug.
Capacitor Charge Ignition
This is an ignition system part that works by passing electrical current over a capacitor. This electric current is stored up quickly in the capacitor before it is released to the spark plug so ignition can take place.
So in this instance, a recoil starter might not be needed.
Spark plug
The work of a spark plug in a Troy Bilt engine is quite simple. It transfers the electric charge to the combustion chamber, where it comes in contact with the air/fuel mixture so that ignition can take place.
Piston
This is a Troy Bilt engine part that we will not see until the engine is overhauled. But the work it does in the engine is very important. It is located in the cylinder block of the engine with the crank shaft.
It has an upward and downward movement that compresses air at very high temperature in the engine block. The whole piston unit consists of piston rings and a piston rod.
Cylinder block
This is another part of a Troy Bilt lawn mower that cannot be seen outwardly. It helps to seal the air that is being compressed for combustion. The spark plug of the lawn mower also has a place in the cylinder block. This is to aid ignition.
Crank shaft
In a Troy Bilt lawn mower, the piston and connecting rod are all connected to the crank shaft. The crank shaft has circular movement, meaning it rotates, but converts this motion to the up and down movement of the piston, which helps to compress air needed for combustion.
Fly wheel
The fly wheel helps to balance the weight and motion of a Troy Bilt lawn mower. On most of them, a fan is attached to it, so that it can help to serve as coolant and prevent over heating in engine parts.
Fuel tank
This is the part that helps to retain the fuel that has been poured into the lawnmower. It is basically a container that houses the fuel. On most lawn mowers, it can be located at the top.
But for Troy Bilt lawn mowers, it can sometimes be located at the bottom, especially if it is a four stroke lawnmower engine.
Oil seal
I know we have already pointed out what an oil filter does in a lawn mower, but the function of an oil seal is quite different. As the name suggests, the oil seal makes sure that oil does not leak out of the engine compartment into other parts of the lawn mower.
This is usually seen in Troy Bilt four stroke lawn mower engines. But for their two-stroke types, the oil seal also doubles as a cover for the compression chamber.
Flexible shaft
The flexible shaft makes it easy to deflect the handle for cutting the grass in different directions. It also serves as a link between the Troy Bilt lawn mower engine and the propeller shaft.
Clutch housing
The housing of the clutch helps to connect the engine of the lawn mower to the handle. It works like a link between the two. So once the engine rate increases, the clutch housing begins to rotate, thereby making the blades spin as well.
But once there is a decrease in the rate of spin of the engine, it means the mower is running on idle. The clutch house will not rotate, so that the blades will also be static.
Cropping handle
This is the part that is being held by the user when the using the lawn mower to cut grass in the yard. For Troy Bilt lawn mowers, the cropping handle is usually equipped with a rotation control lever and a button to stop the lawn mower.
The cropping handle is also equipped with a handrail that makes it easy to direct the lawn mower blade in the direction you want it to cut.
Lawn mower blade
This is the part of the lawn mower that does the actual grass cutting. In Troy Bilt lawn mowers, the blades can be of two types: plate or disc. Whichever type your model comes with, there is no problem. They all perform excellently when mowing your lawn.
Wheel and tires
The lawn mower has to be moved around, and this is where the tires come in. These tires are held in frame by a wheel.
The wheel and tire setup for Troy Bilt lawn mowers are sturdy, durable and strong enough to withstand road shock and vibrations. They are also useful for hilly and bumpy roads.
BASIC MAINTENANCE OF TROY BILT MOWER PARTS
For most of the unseen parts of the lawn mower to work well, there are some basic things we need to do to parts of the lawn mower we can see. Some of these include:
- Check the oil level often to make sure that it is in its proper gauge. You can use the dipstick to gauge it. But remember to wipe the dipstick every time before you put it back in.
- Still on the oil maintenance, make sure you use the actual oil stipulated by Troy Bilt for their lawn mowers, as different oils have different properties and effects on your engine.
- We also advice that you do not use old oil for your Troy Bilt lawn mower. Once the oil in your lawn mower has sat there unused for about a month, it is recommended that you drain it from the tank completely.
- It is also important to clean the air filter from time to time. This is because while mowing, dirt and debris can get trapped in the air filter. Over time, if left unattended, it could damage the filter itself.
- It is also very important to sharpen your lawn mower blades. The truth is that a blunt lawn mower blade will give the engine more work to do and cause damage to it faster.
- Also, make a habit of cleaning your spark plug. You can use the bristle of a tooth brush to achieve this. But remember to always disconnect the spark plug wire before working on the spark plug.
- On a general note, it is also important to disconnect the spark plug wire before carrying out any form of servicing and maintenance.
Conclusion
Troy Bilt products are very durable and have good quality. Their lawn mower spare parts are readily available in retail stores. As earlier stated, make sure you maintain the parts that you can often see, so that the parts not easily seen can function properly.
