Have you ever felt like your lawnmower is just skimming the surface of your grass, leaving behind an uneven and shaggy lawn? It’s frustrating, right? You want a crisp, clean cut, but your Craftsman lawnmower just won’t cooperate. The culprit? Your mower blade might be set too high! This article will walk you through the process of adjusting the cutting height on your Craftsman mower, ensuring you get the perfect lawn every time.
Understanding the Importance of Blade Height
The height of your mower blade plays a crucial role in the appearance and health of your lawn. A blade set too high can leave your grass long and uneven, while a blade set too low can scalp your lawn, damaging the grass roots and leaving it vulnerable to disease. Finding the sweet spot is crucial for a healthy, aesthetically pleasing lawn.
Identifying Your Mower Type: Self-Propelled vs. Push
Craftsman mowers come in both self-propelled and push varieties. Each type has its own method for adjusting the blade height, so it’s important to identify your specific model before proceeding.
Self-Propelled Craftsman Mowers
Self-propelled Craftsman mowers typically have a lever or a series of levers located on the side of the mower deck. These levers control the height of the blade and are usually numbered to indicate the different cutting height options.
Push Craftsman Mowers
Push Craftsman mowers often have a lever or a series of levers located on the back of the mower deck. This lever or set of levers will control the height of the blade, similar to the self-propelled models.
Locating the Blade Height Adjustment Mechanism
Once you’ve identified your mower type, you’ll need to find the blade height adjustment mechanism. This is typically a lever or a series of levers that control the height of the mower deck.
Steps for Finding the Adjustment Mechanism:
- Locate the Deck: The mower deck is the metal housing that encloses the blade.
- Look for Levers: Examine the deck carefully for a lever or a set of levers.
- Check for Labels: Some mowers have labels indicating the function of the levers, while others have numbers to denote the different cutting heights.
Adjusting the Blade Height on Your Craftsman Mower
Now that you’ve located the blade height adjustment mechanism, it’s time to lower the blade. Here’s how:
1. Preparation:
- Safety First: Before you begin, disconnect the spark plug wire to prevent accidental starts.
- Clear the Area: Make sure the area around the mower is clear of debris, tools, and people.
2. Adjusting the Height:
- Lever System: If your mower has a lever system, simply move the lever to the desired height setting. Many mowers have markings or numbers on the lever to indicate the different cutting heights.
- Multiple Levers: Some mowers may have multiple levers, each controlling a different section of the deck. Make sure all levers are adjusted to the desired height.
3. Test the Adjustment:
- Reattach the Spark Plug Wire: After adjusting the blade height, reattach the spark plug wire to the spark plug.
- Test Cut: Make a small test cut in a section of your lawn to ensure the blade is at the desired height. Adjust the levers again if necessary.
Understanding Blade Height Markings
Most Craftsman lawnmowers will have markings or numbers on the blade height adjustment lever or levers. These markings indicate the different cutting height options available on your mower. Here’s a quick guide to understanding these markings:
Typical Blade Height Markings:
- Numbers: Many mowers use numbers to indicate the blade height, with lower numbers representing a lower cut. For example, 1 might be the lowest setting and 5 might be the highest.
- Inches: Some mowers will have markings in inches, such as “1 inch” or “2 inches,” indicating the height of the blade above the ground.
Important Note: The specific markings on your mower may vary, so it’s important to consult your owner’s manual to understand the height options available to you.
Factors to Consider When Choosing Blade Height
The ideal blade height for your lawn will depend on several factors, including the type of grass you have, the time of year, and your personal preferences. Here are some general guidelines:
- Grass Type: Different types of grass have different optimal cutting heights. For example, fescue grass often thrives with a cutting height of 2-3 inches, while Bermuda grass can tolerate a shorter cut of 1-2 inches.
- Time of Year: You may need to adjust the blade height throughout the year depending on the weather conditions and the growth rate of your grass. In the summer, when grass grows quickly, you might need to mow more often and at a slightly higher setting to avoid scalping.
- Personal Preference: Ultimately, the best blade height for your lawn is the one that you find aesthetically pleasing and that allows your grass to thrive.
Troubleshooting Blade Height Problems
Sometimes, you might experience issues adjusting the blade height on your Craftsman mower. Here are a few common problems and their solutions:
1. Stuck Levers: If the levers are stuck or difficult to move, they might be clogged with dirt or debris. Clean the levers and the surrounding areas with a brush or compressed air to free them up.
2. Worn-Out Parts: If the levers are still stuck after cleaning, the problem might be with worn-out parts, such as the lever mechanism or the deck springs. These parts may need to be replaced.
3. Bent Deck: If your mower deck is bent, it might prevent the blade from being adjusted properly. This issue typically requires a repair or replacement of the deck.
4. Wrong Adjustment: If you’re having trouble adjusting the blade height, double-check that you’re using the correct adjustment method for your specific model of Craftsman mower. Consult your owner’s manual if you’re unsure.
Maintaining a Sharp Blade
A sharp blade is crucial for a clean cut and a healthy lawn. A dull blade will tear the grass blades instead of cutting them cleanly, leaving them vulnerable to disease.
Signs of a Dull Blade:
- Ragged Edges: The grass blades will have a jagged or torn appearance.
- Grass Ripping: You may hear the mower ripping or tearing the grass.
- Uneven Cut: The lawn will have an uneven appearance, with some areas cut shorter than others.
Sharpening Your Blade:
- Tools Needed: You’ll need a sharpening file, a vise, and a pair of safety glasses.
- Safety First: Wear safety glasses and gloves to protect yourself from flying metal chips.
- File the Blade: File the blade’s edge with a sharpening file, moving in one direction at a consistent angle.
- Balance the Blade: Make sure the blade is balanced after sharpening to prevent vibration and damage to your mower.
Conclusion
Adjusting the blade height on your Craftsman lawnmower is a simple yet essential task for achieving a healthy and beautiful lawn. By following the steps outlined in this article, you can ensure that your mower is cutting at the optimal height for your grass type and preferences. Remember to also maintain a sharp blade for a clean cut and a healthy lawn. With a little care and attention, your Craftsman mower will be your go-to tool for creating the perfect lawn you deserve.

2. How do I know if my Craftsman lawn mower blade needs to be lowered?
There are a few signs that indicate your Craftsman lawn mower blade needs to be lowered. The most obvious is if your lawn is being scalped, meaning the blades are cutting too close to the ground. You’ll notice uneven patches in your lawn, or even bare spots where the grass has been completely removed. You might also notice a lot of grass clippings left behind, indicating the blades aren’t cutting cleanly.
Finally, if you feel like your lawn isn’t getting the close cut you desire, then lowering the blades may be the solution.
3. How do I lower my Craftsman lawn mower blade?
Lowering your Craftsman lawn mower blade is a simple process. First, locate the height adjustment lever on your mower. It is usually located near the wheels, and there will be markings indicating different height settings.

For safety, it’s best to disconnect the spark plug before making any adjustments to your mower.
4. How low should I lower my Craftsman lawn mower blade?
The ideal height for your Craftsman lawn mower blade depends on the type of grass you have and your personal preference. For most types of lawns, a blade height of 2-3 inches is recommended. However, if you have a thick, lush lawn, you may be able to lower the blade to 1.5-2 inches.
