Remember that sweltering summer day when you finally decided to tackle the overgrown backyard? You looked at that jungle of grass, taller than your knees, and wondered, “Can I cut long grass with a lawn mower?” This post will answer that question definitively, exploring the challenges, techniques, and best practices for tackling tall grass with your mower, saving you time and effort in the process.
Mowing Very Long Grass: Challenges and Considerations
Successfully mowing exceptionally long grass requires careful preparation and the right approach. Ignoring these factors could damage your mower or lead to an uneven cut. This section details the key challenges and how to overcome them.
Mower Type and Capabilities
Not all lawn mowers are created equal. The type of mower you own significantly impacts your ability to cut long grass. Rotary mowers, for example, are generally better suited for taller grass than reel mowers.
- Rotary Mowers: These mowers use a spinning blade to cut grass, making them more effective at tackling taller, thicker growth. They’re generally more powerful and better at handling uneven terrain.
- Reel Mowers: Reel mowers use a cylinder with rotating blades to shear the grass. While offering a very clean cut, they are usually only suitable for shorter, more evenly distributed grass.
Blade Sharpness and Maintenance
- Importance of Sharp Blades: Dull blades tear the grass, leading to ragged edges, brown tips, and increased stress on your lawn. Sharp blades provide a clean cut, promoting healthier growth. Consider sharpening or replacing your blades before tackling long grass. A good rule of thumb is to sharpen them every 3-5 mowing sessions.
- Regular Maintenance: Before attempting to cut very long grass, check your mower’s oil, air filter, and spark plug. Ensuring your mower is in good working order will prevent unexpected breakdowns mid-job. Regular maintenance extends the lifespan of your machine.
Engine Power and Capacity
The engine size of your mower is a key factor in how well it performs with long grass. A smaller engine might struggle, leading to stalling and inefficient cutting.
- Engine Size: Larger engines generally provide more power, enabling them to cut through thicker, taller grass more easily. Consider the engine horsepower relative to the size of your lawn and the grass height.
- Mulching Capabilities: Some mowers have mulching capabilities, which chop the grass clippings into fine pieces and return them to the lawn as fertilizer. Mulching is beneficial for long grass, as it helps to recycle nutrients.
Techniques for Cutting Very Long Grass
Once you’ve assessed your mower and prepared accordingly, it’s time to tackle the task. Using the correct technique prevents damage to your equipment and ensures a more even cut. This section outlines the best practices for mowing long grass.
Step-by-Step Guide to Mowing Long Grass
- Initial Cut: Set your mower’s cutting height to its highest setting. This will allow for an initial cut without overwhelming the engine or clogging the blades. Make multiple passes over the same area, slowly cutting down the height gradually.
- Reduce Height Gradually: Once the grass is significantly shorter, gradually lower the cutting height to achieve your desired final length. Do this in incremental steps to prevent overwhelming the mower.
- Multiple Passes: For very long grass, multiple passes are necessary. Attempting to cut all the grass down in a single pass will likely result in clogging and poor results. Overlap each pass slightly to ensure complete coverage.
Dealing with Thick or Wet Grass
Thick or wet grass presents unique challenges. The additional density and moisture can make cutting significantly harder. To avoid problems, consider the following strategies:
- Allow Grass to Dry: If possible, avoid cutting wet grass. Wet grass is heavier and more likely to clump, clogging the mower and leading to uneven cuts. Cutting dry grass significantly reduces these issues.
- Multiple, Lighter Passes: For very thick grass, multiple, lighter passes are often better than a single heavy pass. This prevents overwhelming the engine and avoids clogging.
Choosing the Right Lawn Mower for Long Grass
The type of lawn mower you choose can significantly impact your ability to effectively cut long grass. Different mowers are better suited to different tasks. This section covers the best types of lawn mowers for tackling overgrown areas.
Rotary vs. Reel Mowers: A Comparison
| Feature | Rotary Mower | Reel Mower |
|---|---|---|
| Suitable for Long Grass | Yes | No |
| Cutting Action | Cuts by chopping | Cuts by shearing |
| Power Requirements | Usually requires more power | Usually requires less power |
| Maintenance | Higher maintenance | Lower maintenance |
Other Mower Types and Their Suitability
- Riding Mowers: These are ideal for large lawns with long grass, offering efficiency and less physical strain. However, they are generally more expensive.
- Zero-Turn Mowers: Provide excellent maneuverability and are great for large, uneven terrains, efficient for long grass but cost more than standard riding mowers.
Troubleshooting Common Problems When Mowing Long Grass
Even with preparation, you might encounter problems. Understanding how to troubleshoot common issues ensures a smooth process and helps prevent mower damage. This section helps you fix some frequently experienced issues.
Clogged Mower Deck
A clogged mower deck is a common problem when mowing long grass. The grass clippings accumulate, hindering cutting performance. Regularly clearing the deck is essential.
- Prevention: Avoid cutting overly thick or wet grass. Make multiple passes to minimize clogging.
- Solution: Turn off the mower and use a stick or brush to remove the accumulated grass clippings. Never reach into the mower deck while it’s still running.
Engine Stalling
Engine stalling indicates the mower is struggling to handle the workload. This could be due to several factors, including a dull blade, clogged mower deck, or lack of engine power.
- Prevention: Sharpen the blades and ensure the mower deck is clear. Consider using a more powerful mower for extensive areas of long grass.
- Solution: Clear the deck, sharpen the blades, check the oil levels and the air filter. Consider taking it in for repair or servicing if the problem persists.
Mythbusting: Long Grass and Your Lawn Mower
Myth 1: You can always cut long grass with any lawnmower.
False. Mowers have limitations. Using the wrong mower for extremely long grass can damage it.
Myth 2: It’s always faster to cut it all at once.
False. Multiple passes at higher settings are usually safer and prevent clogging.
Myth 3: You don’t need to prep before cutting long grass.
False. Preparation is crucial, including blade sharpening and mower maintenance.
FAQ
Can I cut grass that’s 12 inches tall with a lawn mower?
Possibly, but it depends on your mower’s capabilities. Start with the highest setting and gradually lower it; otherwise, it could lead to clogging and damage your equipment.
What’s the best type of lawn mower for long grass?
Rotary mowers are generally best. Riding mowers are ideal for large areas of long grass.
How often should I sharpen my mower blades?
It’s recommended to sharpen your blades every 3-5 mowing sessions for optimal cutting performance.
What should I do if my mower starts stalling while cutting long grass?
Check the mower deck for clogs, the blades for sharpness, and oil and air filter levels. You may need to switch to a higher setting. If it continues, seek professional help.
My lawn mower keeps clogging. What can I do?
This likely means you’re cutting grass that’s too long or too wet. Try multiple passes at higher cutting heights, letting the grass dry if necessary.
Is it better to cut long grass in sections or all at once?
Cutting in sections is always better, especially with tall grass. This prevents clogging and ensures an even cut.
Can I use a weed wacker before using my lawnmower on long grass?
Yes, using a weed wacker to trim the very tallest areas beforehand can help reduce strain on your mower.
