What are the Common Types of Lawn Mower Springs?
Lawn mower springs are essential components that provide tension and support for various functions. They are typically made of high-quality steel for durability and resistance to wear and tear. Here’s a breakdown of the most common types of lawn mower springs:
- Recoil Starter Spring: This powerful spring is responsible for retracting the starter rope, enabling you to start your mower with a pull.
- Deck Height Adjustment Springs: These springs are located under the mower deck and help you adjust the cutting height of your lawn.
- Blade Engagement Spring: This spring controls the blade engagement mechanism, ensuring the blade is only engaged when you are ready to mow.
- Clutch Spring: This spring, found in self-propelled mowers, engages the drive system, allowing you to move the mower without pushing.
Recognizing the Signs of a Faulty Spring
A broken or worn-out spring can cause various issues, disrupting the smooth operation of your lawn mower. Here are some common signs that your mower spring might need attention:
- Difficult Starting: If you’re experiencing a tough time starting your mower, it could be a sign of a faulty recoil starter spring. The spring might be worn out, failing to retract the starter rope effectively.
- Inconsistent Cutting Height: Difficulty adjusting the cutting height or inconsistent cutting results can indicate a problem with the deck height adjustment springs. These springs may be weakened or broken, preventing proper height adjustment.
- Blade Not Engaging: If the blade doesn’t engage when you pull the lever, or if it disengages unexpectedly, there could be an issue with the blade engagement spring.
- Mower Not Self-Propelled: A broken clutch spring can render a self-propelled mower useless, as the drive system won’t engage.
Gathering the Necessary Tools
Before you embark on your spring replacement journey, make sure you have the right tools on hand. This will ensure a smooth and efficient repair process:
- Screwdriver: A variety of screwdrivers, including Phillips head and flathead, will be useful for disassembling and reassembling the mower components.
- Wrench: A wrench set will be necessary for loosening and tightening nuts and bolts during the repair.
- Pliers: A pair of pliers will come in handy for gripping and manipulating small components.
- Safety Glasses: Always wear safety glasses to protect your eyes from flying debris or particles during the repair.
- Work Gloves: A pair of work gloves will provide a secure grip and protect your hands from sharp edges.
- New Spring: Make sure to have a replacement spring that is compatible with your lawn mower model. You can find the correct spring online or at your local hardware store.

FAQ
Q1: What is a lawnmower spring and why is it important?
A lawnmower spring is a vital component that helps regulate the tension and movement of the cutting deck. It’s often found in the deck’s height adjustment mechanism, ensuring a smooth and even cut across your lawn. The spring also prevents the deck from bouncing or vibrating excessively, contributing to a cleaner and more consistent cut.
Without a properly functioning spring, your lawnmower’s cutting height may be inconsistent, leading to uneven patches in your lawn. The deck could also become unstable, making the mower difficult to maneuver and potentially damaging your lawn.
Q2: How can I tell if my lawnmower spring is broken or needs replacing?
There are a few signs that your lawnmower spring might be out of whack:
- Difficulty adjusting the cutting height: If you have trouble setting the desired height or the deck doesn’t stay in place, the spring may be stretched or broken.
- Uneven cutting: If your lawnmower is leaving uneven patches or scalping the grass, the spring might not be providing enough tension to the deck.
- Excessive bouncing or vibration: A worn or broken spring can lead to vibrations that make the mower difficult to control.
Q3: What tools do I need to fix a lawnmower spring?
The tools you’ll need depend on the specific type of spring and the location on your mower. Generally, you’ll need:
- A wrench or socket set: To loosen and tighten the nuts or bolts holding the spring in place.
- Pliers: To grip and manipulate the spring.
- A screwdriver: To remove any screws that may be obstructing access to the spring.
- A new spring: Make sure you purchase a spring specifically designed for your lawnmower model.
Q4: How do I replace a lawnmower spring?
Replacing a lawnmower spring is a relatively simple process:
- Locate the spring: It’s usually found near the cutting deck’s height adjustment mechanism.
- Remove the old spring: Use your tools to loosen and remove the nuts, bolts, or screws holding the spring in place.
- Install the new spring: Carefully position the new spring in its designated location and secure it with the nuts, bolts, or screws.
- Test the adjustment: Adjust the cutting height and check to ensure that the deck moves smoothly and stays in place.
Q5: Is it safe to replace the spring myself?
Replacing a lawnmower spring is generally a safe process, especially if you have basic mechanical knowledge and follow the correct steps. However, it’s crucial to disconnect the spark plug wire before working on any lawnmower to avoid accidental starting.
If you’re uncomfortable working on the mower yourself, it’s best to consult a qualified mechanic for assistance.
Q6: How often should I replace my lawnmower spring?
There’s no definitive answer to this question as the lifespan of a spring depends on its quality, usage frequency, and general maintenance. However, it’s a good practice to inspect the spring regularly for signs of wear and tear, such as rust, cracking, or stretching.
If you notice any of these signs, it’s recommended to replace the spring to prevent potential problems and ensure optimal performance.
Q7: What are some other maintenance tips for my lawnmower?
Regular maintenance is crucial for keeping your lawnmower running smoothly and extending its lifespan. Here are some additional tips:
- Check the blade sharpness: A sharp blade provides a clean cut and prevents scalping.
- Clean the air filter: A clean filter ensures proper airflow to the engine.
- Change the oil and spark plug: These components wear down over time and need to be replaced regularly.
