The sweet smell of freshly cut grass, the satisfying hum of your lawnmower, and the pride of a perfectly manicured lawn – these are the joys of homeownership. But what happens when your trusty mower suddenly sputters to a halt, leaving you with a tangled mess of grass and a feeling of frustration? If the culprit is a faulty ignition coil, you’re probably wondering, “How much is a coil for a lawnmower?”
This article will explore the world of lawnmower ignition coils, delving into their function, the factors that affect their price, and providing insights to help you make an informed decision when replacing yours.
Short Answer: The cost of a lawnmower coil can range significantly, typically between $20 and $100, depending on the make and model of your mower, the type of coil needed, and where you purchase it.
Understanding the Ignition Coil: The Spark Behind Your Lawn Mower
The ignition coil is a vital component in your lawnmower’s engine, acting as the key player in sparking combustion. It converts the low-voltage electricity from your battery into high-voltage electricity, generating the spark needed to ignite the fuel-air mixture in the combustion chamber. Think of it as the heart of your engine, pumping the lifeblood of ignition.
How Does a Lawn Mower Coil Work?
- Power Input: The ignition coil receives low-voltage electricity from your lawnmower’s battery.
- Magnetic Field: This electricity passes through a coil of wire, creating a magnetic field.
- High-Voltage Output: The magnetic field is then interrupted, causing a sudden change in the magnetic field and generating a high-voltage electrical pulse.
- Spark Creation: This high-voltage pulse is directed to the spark plug, creating the spark that ignites the fuel-air mixture.
Without a functioning coil, your lawnmower won’t be able to produce the sparks necessary to ignite the fuel and will fail to start.
Factors Affecting the Price of a Lawn Mower Coil
The cost of a new ignition coil can vary considerably, influenced by several key factors:
1. Lawn Mower Brand and Model
The brand and model of your lawnmower play a significant role in the cost of the coil. Some manufacturers use proprietary coils that are only compatible with their specific models, which can drive up the price.
2. Type of Coil
There are two main types of ignition coils commonly found in lawnmowers:
- Single-Coil System: This type of coil has a single winding and generates a spark for one spark plug. It is typically found in simpler lawnmowers.
- Dual-Coil System: These coils have two windings and generate sparks for two spark plugs. They are often used in larger and more powerful engines.
Dual-coil systems usually cost more than single-coil systems due to their more complex design.
3. Coil Quality
Like any other automotive part, ignition coils can vary in quality.
- OEM (Original Equipment Manufacturer): These coils are specifically designed for your particular mower model and are often the most expensive option, but offer the best fit and performance.
- Aftermarket Coils: These coils are made by third-party manufacturers and can be cheaper than OEM coils. However, it’s essential to ensure they are compatible with your lawnmower.
4. Purchase Location
Where you purchase your coil can significantly impact the price.
- Dealership: Dealerships typically carry OEM parts but can be more expensive.
- Online Retailers: Online retailers often offer a wide selection of coils at competitive prices, but you need to carefully check compatibility before purchasing.
- Local Hardware Stores: Hardware stores may offer a limited selection of coils but can be a convenient option if you need a quick replacement.
Tips for Buying a Lawn Mower Coil
- Identify Your Lawn Mower Model: Knowing your lawnmower’s brand, model, and engine type is essential to ensure you purchase the correct coil. Check the manufacturer’s plate or your owner’s manual for this information.
- Compare Prices: Shop around for the best price on a coil by checking multiple retailers, both online and offline.
- Read Reviews: Check customer reviews to get an idea of the quality and performance of different coils.
- Consider Compatibility: Ensure the coil you choose is compatible with your lawnmower model, particularly if you are buying an aftermarket coil.
Replacing a Lawn Mower Coil: A DIY Project?
Replacing an ignition coil is generally considered a relatively simple task, even for beginners. However, the complexity and accessibility of the coil can vary depending on the make and model of your lawnmower.
Steps to Replace a Lawn Mower Coil
- Disengage the Spark Plug Wire: Disconnect the spark plug wire from the coil to prevent any accidental sparks.
- Disconnect the Electrical Connections: Disconnect any electrical connections to the coil, ensuring you note the position of each wire.
- Remove the Mounting Screws: Remove the screws securing the coil to the engine block or mounting bracket.
- Install the New Coil: Carefully align the new coil and connect the electrical connections, ensuring they are securely connected.
- Secure the Coil: Tighten the mounting screws to secure the coil in place.
- Reconnect the Spark Plug Wire: Reconnect the spark plug wire to the coil.
It is important to consult your lawnmower’s manual for specific instructions on replacing the coil, as the process can vary slightly depending on the model.
Saving Money on Lawn Mower Coils: Tips and Tricks
- Check for Compatibility: Avoid unnecessary purchases by ensuring the coil you choose is compatible with your lawnmower model.
- Consider Used Parts: If you’re on a tight budget, check online marketplaces or local used parts sellers for a used but functional coil.
- DIY Installation: Replacing the coil yourself can save you labor costs.
- Regular Maintenance: Regular maintenance, including cleaning the spark plug and ensuring proper fuel mixture, can help prolong the life of your ignition coil.

FAQ
What is a coil in a lawn mower?
A coil, also known as an ignition coil, is a crucial component in a lawn mower’s ignition system. It transforms the low voltage from the battery into high voltage, which is necessary to create a spark that ignites the fuel-air mixture in the combustion chamber. This spark is what powers the engine and drives the mower blades. Without a functioning coil, the engine won’t start or run.
There are different types of coils used in lawn mowers, including solid state coils, electronic coils, and points-type coils. The type of coil will depend on the mower’s age and model.
How much does a lawn mower coil cost?
The cost of a lawn mower coil can vary significantly depending on factors like the brand, type, and model of the mower. In general, basic coils for standard lawn mowers can range from $20 to $50. However, coils for newer or more advanced mowers, including those with electric starters or electronic ignition systems, can cost more, reaching upwards of $100 or more. It is always best to research the specific coil for your lawn mower and compare prices from different retailers to find the best deal.
