The best way to mow your lawn without leaving pesky, unsightly lines is by using a high-quality, self-propelled mower that’s in tiptop condition. If you know that’s not the problem, then you may have internal issues with the mower or you’re using it the wrong way. There are other possibilities as well, but these are usually the culprits.
What Internal Issues Might Need Checking to Mow without Leaving Lines?
First, check the machine to see if it doesn’t have internal problems that are causing the lines. There are several possibilities that could make the lines to appear unintentionally. Most of this will be due to the blades but it could also be an issue with the fuel.
If the blades are too small or too blunt, this will surely create lines in the grass you don’t want. There could be other issues with the blades such as poor maintenance and cleaning. But, the fuel you’re using could be wrong or old.
How Can the Blades Create Dreaded Lawn Lines?
Sometimes, blades being too small come after having them replaced. This is a common occurrence for mowers that cut grass beautifully for years. After sending them off for a replacement, lines begin showing up that didn’t occur before.
If the blades are too small, they won’t be able to reach across and cut the whole row, leaving small gaps in between. Conversely, if the blades aren’t sharp enough, not only will they leave lines, but they can also damage your grass. Ensure you sharpen your blades once or twice a year to keep them in good condition.
There could be other blade issues leading to poor cutting results too. If the blades are in the wrong direction, debris builds up on them or if there’s damage to the blades, it will cause those pesky lines to streak across your beautiful lawn.
Are There Any Other Blade Issues that Can Create Lines in the Grass?
Curling, warping or any other kind of defect will affect how the mower cuts the grass. These can lead to unsightly lines. Other issues could include things like misalignment, blades that revolve the wrong way or some disorientation. So, you’ll have to get them inspected and replaced if you notice any damage.
Will the Fuel Be a Factor in a Mower Creating Lines on the Lawn?
When it’s not the blades, check out the fuel mechanisms in the machine. Ensure you’re using the right fuel recommended by the manufacturer. Believe it or not, the wrong fuel will create performance issues for the mower and can result in lines.
Also, don’t use old gas from the previous season because it loses its quality after four weeks of sitting inside the engine. This gums up and sticks inside the carburetor which can reduce the mower’s performance and smoothness of flow. This will result in sluggishness and those dreaded lawn lines.
What Am I Doing Wrong that Creates Lawn Lines?
Next, check the mower’s settings and your own mowing technique. If your engine is performing poorly, and it isn’t the fuel or the blades, you could simply have the settings wrong. Put it on the lowest setting and see if any lines appear.
Mowing too Fast
If you are mowing to quick or you aren’t overlapping the rows, it causes lines to appear. Mowing your lawn too fast is the most common reason for undesirable lines. So, try to go a little slower next time and be patient. Avoid allowing the engine to operate at full throttle.
You’re Not Overlapping Correctly
Overlapping the rows is another common mistake people make that creates lines on the lawn. Ensure you always leave a bit of space between the columns you mow. If you don’t leave a gap, the blades will pull upwards and the tires press downwards – this is how such lines develop in the grass.
General Poor Mowing Technique
It’s not enough to mow the edges of the rows previously cut. You have to spare a couple inches on the row so you can cut the line the tire mowed over. If you don’t, the lines you created will be even deeper than before. So, be mindful with your technique.
Are There Any Other Possible Causes for Lawn Lines from a Mower?
Of course there are a number of other things you could also be doing wrong. There are various styles, methods and patterns you can use that can accommodate your lawn better while avoiding the creation of lines. The following are some of the most important points to consider in this regard:
- Ensure the engine runs at an optimal speed: Play with the settings to guarantee you have the mower at the most ideal speed possible. Inadequate speeds will display poor cutting results. If you force the engine or don’t apply enough force, it can create undesirable lines in the grass.
- Wrong tire pressure: Uneven tires or ones too heavily inflated will leave an undesirable line pattern on your grass. Always abide the manufacturer’s instructions and recommendations for tire pressure, size and type. When in doubt, contact the store where you bought the machine or the manufacturer.
- Be mindful of your mowing pattern: An intentional and deliberate mowing pattern is essential to ensuring you don’t have any lines on your lawn. Turn slow, don’t mow too quick and take your time. Check to see if you missed any spots before you put the machine away.
- Inappropriate mowing pattern: Some lawns don’t benefit from the traditional back-and-forth lines. There are certain situations where using concentric circles or double spirals are better. This will be ideal for lawns with lots of hills, dips or ones with an asymmetrical layout.
- Lack of cleaning and maintenance: If you use your mower often, the underside will be a magnet for debris, grass clippings, dirt, small pebbles and other lawn waste. This buildup can clog the deck of the machine. Make sure you check and clean it often.
