Have you ever wondered, why is my lawn mower spitting out grass? This common issue can frustrate any homeowner trying to maintain their yard. Not only does it make your lawn look messy, but it also indicates that something isn’t working correctly with your lawnmower. In this comprehensive blog post, we’ll explore the reasons behind this problem and provide practical solutions to get your mowing back on track.
Introduction
A well-maintained lawn is a joy to behold. However, the process of achieving such an aesthetic spectacle often involves using a reliable lawnmower. But what happens when your trusted tool starts acting up and spitting out grass clippings? This irregular operation can put a damper on your lawn maintenance routine and leave you with an untidy yard.
Understanding why your lawnmower is spitting out grass instead of collecting it requires a basic comprehension of how the machine works. After cutting the grass, the mower’s blade creates an airflow that propels the clippings into the collection bag. If anything disrupts this process, the grass might end up everywhere except inside the bag. Now, let’s delve into some of the reasons why this could be happening.
Reason #1: Clogged Grass Chute
A clogged grass chute is one of the most common reasons why a lawnmower might spit out grass. The chute is a passage that directs the cut grass from the blade to the collection bag. If this chute gets blocked, the grass has nowhere else to go and is thus expelled in all directions. Wet or long grass, mud, and leftover grass from previous mowing sessions are often responsible for these clogs.
Tips for clearing the obstruction and preventing future clogs
Cleaning a clogged chute is relatively simple. Ensure the machine is switched off before you try to clear the obstruction to avoid accidents. A stiff brush or a hose can help dislodge stubborn clumps of grass. To prevent future clogs, make sure to clean the chute after each mowing session. Also, avoid mowing wet grass as it tends to stick together and form blockages.
Reason #2: Cutting Grass Too Short
Cutting grass too short can contribute to your lawnmower spitting out grass. When the grass is cut too short, the mower blade can skim the soil surface, picking up mud and debris. This unwanted material can clog the grass chute and cause the lawnmower to expel grass clippings erratically.
Tips for adjusting the cutting height to prevent the issue
To prevent this problem, adjust your mower’s cutting height. A good rule of thumb is to never remove more than one-third of the grass blade length at a time. This practice not only prevents clogging but also promotes healthier grass growth. Remember to adjust the mower height according to the type of grass and the season.
Reason #3: Improperly Fitted Collection Basket
If the collection basket isn’t fitted correctly, it won’t collect the grass clippings efficiently. Instead, the mower will spit them out, resulting in a messy lawn. Improper fitting can happen due to a loose attachment or damage to the basket.
Tips for ensuring the collection basket is properly installed
Ensure the collection basket clicks into place correctly every time you attach it. If it’s damaged, consider replacing it to ensure a snug fit. Regularly check the basket for signs of wear and tear. A well-fitted and damage-free collection basket ensures efficient grass collection and a tidier lawn.
Reason #4: Blunt or Incorrect Blade
A blunt or incorrect blade can also cause your lawnmower to spit out grass. A dull blade tears the grass instead of making clean cuts, leading to larger and uneven clippings that are harder to propel into the collection bag. An incorrect blade, on the other hand, may disrupt the airflow needed for efficient grass collection.
Tips for sharpening or replacing the blade and choosing the correct blade for the mower
Regularly sharpen your mower blades to keep them in top condition. Remember that a ragged cut grass blade is more susceptible to disease. If necessary, consider getting professional help for blade sharpening to ensure the job is done correctly. If the blade is bent or damaged, replace it. Always refer to the user manual or consult a professional when choosing a replacement blade to ensure compatibility with your mower model.
Reason #5: Worn-out Deck Belt and Underinflated Tire
A worn-out deck belt and underinflated tire can significantly affect your mower’s performance. The deck belt transfers power from the engine to the blade, enabling it to spin. If the belt is worn out, the blade may not spin optimally, resulting in poor grass cutting and collection. Similarly, underinflated tires can create an imbalance, causing the mower to cut unevenly and spit out grass.
Tips for replacing the deck belt and maintaining proper tire inflation
Regularly inspect the deck belt for signs of wear, and replace it if necessary. Make sure to choose the right belt size for your mower model. As for the tires, check the pressure regularly and maintain it within the manufacturer’s recommended range. Balanced tire pressure ensures even cutting and reduces the chances of your lawnmower spitting out grass.
Conclusion
In conclusion, several factors can cause your lawnmower to spit out grass, including a clogged grass chute, cutting grass too short, an improperly fitted collection bag, a blunt or incorrect blade, and a worn-out deck belt or underinflated tire. By understanding these reasons, you can troubleshoot effectively when you encounter this problem. Regular maintenance and proper operation of your lawnmower can prevent these issues and ensure efficient grass collection for a neat and tidy lawn.
