Worx Electric Mower Has a Bad or Uneven Cut (9 Causes)

When you notice your mower is no longer giving you a good cut, it’s time to inspect the mower for damaged or worn parts.

A WORX electric mower may have a bad or uneven cut due to a damaged wheel; dull, bent, or worn mower blade; wrong mower deck height, fast ground speed, or plugged mower deck.

Keep reading for more items that will give you a bad cut with your WORX mower including installing the blade incorrectly.

Follow all safety precautions including shutting off the mower, removing the battery, and waiting for all parts to stop moving before troubleshooting.

Your WORX Electric Mower Cuts Uneven

1. Damaged Wheel on a WORX Electric Mower

The first thing to do when you notice you are getting a bad cut because your WORX mower is cutting unevenly is to check for a damaged wheel.

A damaged wheel can cause the mower to sit unleveled. This means your deck will sit closer to the ground on one side of the mower than the other. When this happens, you will get an uneven cut.

The wheels on a push mower can come loose or become damaged causing the mower not to sit level. Inspect the wheels. Tighten any loose hardware and replace any damaged wheels.

2. Mower Blade is Worn or Dull on a WORX Electric Mower

The next thing to look at is the WORX mower blade. When the blade becomes worn, it won’t make a good cut through the grass. A worn blade will just end up tearing the grass.

You’ll notice this when your lawn turns brown a day or two after you mow. The tips of the grass turn brown because the grass is being beaten up and torn by a dull blade.

Next time you experience a lawn where the tips turn brown, grab a handful of grass and take a look at the tips. Do they have little tears in them? If so, this is a sign your WORX mower blade may need sharpening or replacing.

Remove your mower blade and sharpen it with a file if they are still in good condition.

When the blade isn’t in good condition because it is extremely worn, has gouges, has rounded blade ends, or the blade sail is thinner than the center of the blade, replace it with a new mower blade.

Just in case you don’t know, the blade sail is the high side of the blade that helps create airflow under the deck to assist with a nice cut.

Balance the WORX mower blade

Make sure the blade is balanced with equal weight on both ends of the blade. A blade can become out of balance when the blade has become unevenly worn by sand that gets sucked into the underside of the mower deck.

Another way a blade becomes uneven is during the sharpening process. When more metal is removed from one end of the blade than the other, the blade becomes unbalanced.

Check your blade balance using a blade balancer. A balancer is relatively inexpensive. It’s worth the investment because an unbalanced blade may cause significant damage to your WORX mower.

Another method to check for a balanced blade is by hanging the blade on a nail that is mounted to your wall with the nail head sticking out of the wall about 3/4″ to 1″.

You will need to remove metal from the end of the blade that is hanging lower until the blade sits level.

3. Mower Blade is Bent on a WORX Electric Mower

When your blade impacts a solid object like a rock, stump, or toy, it can bend causing your WORX mower to give a bad cut.

To prevent damage to the blade, it’s a good idea to walk the lawn to make sure there’s nothing in the way that you may run over and damage the mower.

A bent blade will cause an uneven cut. It can also cause your mower to start vibrating. Sometimes a bent blade is obvious and sometimes not so the best way is to remove the blade.

Make sure your mower is parked on a flat-level surface and remove the battery pack(s). Wait for all moving parts to stop moving before working under the mower deck.

  • Check for a Bent WORX Mower Blade By Removing the Blade
    Remove the blade and lay it on top of a new WORX mower blade. This is the best way to verify whether or not your blade is bent. Even a very slight bend can cause a bad cut.

NEVER attempt to straighten a bent mower blade to reuse it. When you do this, the metal is compromised and becomes weakened.

It is possible for the weakened area to break off and fly out of your mower deck at high speeds. This could cause injury or damage to people, pets, or objects in the area.

4. Mower Blade is Installed Incorrectly on a WORX Electric Mower

You can damage your WORX mower by using the wrong blade or installing it incorrectly. Make sure the blade is installed with the sail in the up position.

The sails are the high sides of the blade that help create air movement to toss the grass. When the blade is installed with the sail facing the ground, damage can occur to the blade motor.

Instead of cutting the grass evenly, the upside-down blade will beat up and tear your grass. It can potentially hit high spots in the ground causing impact to the blade and potential damage to the motor.

You may find your WORX mower blade is stamped indicating which side of the blade should be facing upward and which side should be facing the ground.

5. Blade is Not Tight on a WORX Electric Mower

When the blade is not securely attached, the blade will fail to rotate causing your mower not to cut the grass. Refer to your operator’s manual for the right torque specs for the blade bolt and tighten accordingly.

6. Cutting Height Setting on a WORX Electric Mower

You can end up with an uneven cut when your mower deck is set too low and it isn’t able to handle the amount of grass without compromising the cut.

Adjust the mower deck height to a higher setting when cutting thick tall grass so you don’t overwork the motor.

When the grass is tall or thick, double-cut or triple-cut your lawn. This is done by setting the mower deck to the highest setting for the first cut. Lower the deck height for each additional cutting until you achieve the cut you want.

7. Mower Deck is Plugged with Grass on a WORX Electric Mower

Your WORX will give you a bad cut when your mower deck is plugged with grass. This is because there is no longer sufficient area under your deck for the blade to create the airflow needed to give a good precise cut.

The mower deck and mower blade are designed to work together to create suction to lift grass so the blade can pass by and provide a nice even cut.

A plugged mower deck can also wear on your motor and cause it to work harder when having to turn the blade through the grass clippings under the deck.

Regularly clean the mower deck to keep it free of grass and dirt buildup using a deck scraper or wire brush. Avoid cutting wet grass. Wet grass will clump and stick to your mower deck.

8. Ground Speed is Too Fast on a WORX Electric Mower

Your ground speed needs to be adjusted to your mowing conditions to receive a good cut.

If you don’t properly adjust your speeds and move too fast through your lawn, your WORX mower will give you a bad or uneven cut because it may just be pushing over some of the grass instead of cutting it.

Your lawn mower is put under a heavy load when it is cutting thick, tall, or wet grass. You must slow down so your mower is better able to handle the load.

In addition to a bad cut, your motor can become overloaded and causing it to shut off.

9. Uneven Lawn

Check the condition of your lawn. If the lawn is uneven, your WORX mower is not going to fix that. You may have ruts and bumps in the lawn so your lawn is no longer even.

I have to roll my lawn every spring after the snow melts to flatten the lawn due to rodents digging tunnels through the yard. Without doing this, I not only get a bad cut but the mower bounces all over the place.

Check your lawn to see if you have any maintenance that needs to be done to keep your lawn flat and in good condition.
