RYOBI Electric Mower Cuts Unevenly (9 Reasons)

You may have noticed that the mower doesn’t make as clean of a cut as it used to. After being mowed, the grass is left looking unsightly due to the fact that it is not even slightly uneven.

It’s possible for a RYOBI electric mower to produce a poor or uneven cut if one of the following issues occurs: the wheel is broken or loose; the mower blade is dull, crooked, or worn; the mower deck height is incorrect; the ground speed is too rapid; or the mower deck is clogged.

In addition, there is a possibility that electric zero-turn mower models have low tire pressure or that the deck of the mower is not level.

Before beginning any troubleshooting, be sure to follow all of the safety procedures that are outlined in your operator’s handbook. This includes turning off the mower, disconnecting the battery, removing the safety key, and waiting for all moving components to cease moving.

Your Electric Battery-Powered RYOBI Lawn Mower Produces Uneven Cuts

1. An Electric Lawnmower from RYOBI with a Broken Wheel or Low Tire Pressure

If either the wheel or the tire are not in good enough condition, one of them will need to be repaired or changed so that the vehicle may continue to be driven. If the tire on your zero-turn mower becomes punctured or loses its air pressure, the deck of your mower will sit lower to the ground on the side of the deck that is impacted by the problem.

This will result in an uneven cut being given to your grass.

  • Walk-behind mower: tighten the hardware on any wheels that are loose. Wheels that are damaged should be replaced.
  • Zero-turn mower: Drive wheels should have their tire pressures checked, and any low tires should have more air added. Check the castor wheels for any signs of damage and replace them if they are damaged in any way.

2. The RYOBI Electric Mower’s Mower Blade Is Worn or Dull

Check out the RYOBI mower blade after you have established that the wheels are in satisfactory condition.

When the blade is too worn to perform well, it will not be able to cut through the grass. A dull blade will do little more than rip the grass blades off at the ends.

If you mow your grass, you can discover this when it goes brown a day or two after you do it. When a dull blade is tearing and mauling the grass, the tips of the grass are becoming brown. This is a sign that the grass is being stressed.

This is a very clear indicator that the blade needs to be sharpened.

It’s possible for the blades on broad format mower decks with several blades to get so worn out that they leave a strip of grass in between each of the blades.


If the blades on your RYOBI electric mower are still in good condition, you may take them off the mower and sharpen them using a file. On the other hand, this action is something that should only be taken if the conditions are correct.

If the existing mower blade is very worn, has gouges, has rounded blade ends, or if the sail of the blade is thinner than the center of the blade, you should replace it with a new one as soon as possible. Another sign that the blade is not in excellent shape and should be changed is if the ends of the blade are rounded.

Adjust the blade tension on the RYOBI mower.

Ensure that the blade is balanced by placing an equal amount of weight on both ends of the blade. Sand that is sucked into the bottom of the mower deck may cause the blade to wear unevenly, which can throw off the blade’s balance and cause it to become unbalanced.

The act of sharpening a RYOBI blade may also result in the blade’s edges becoming uneven. The blade becomes imbalanced when more metal is taken from one end of the blade than is removed from the other end.

Use a blade balancer to ensure that your blade is properly balanced. A balancer will not cost you an exorbitant amount of money. Considering that a blade that is not correctly balanced has the potential to do significant damage to your RYOBI mower, it is essential to make this investment.

Another method for assessing whether or not a blade is balanced is to hang it from a nail that has been placed to your wall in such a manner that the nail head protrudes from the wall between three quarters of an inch and one inch.

You will need to remove some metal from the end of the blade that is hanging down in order to bring the blade to a position where it is level with the rest of the blade.

3. A Mower Blade that Is Not Straight on My RYOBI Electric Mower

It is possible for the blade of your RYOBI mower to get bent if it collides with a solid item such as a rock, a stump, or a toy. This will result in an uneven cut.

It is a good idea to walk the lawn before you mow it to make sure there is nothing you may run over that would cause damage to the mower’s blade. This will help prevent the blade from being damaged.

An uneven cut will result from a blade that is bent. It is also possible for the mower to begin vibrating as a result of this. A vibration and an uneven cut may be caused by even the tiniest bend in the material.

Before you remove the battery pack(s) and safety key from your mower, you need to make sure it is parked on an area that is both flat and level. Before operating beneath the mower deck, you must first wait for all moving components to come to a complete stop.

  • Remove the blade from the RYOBI mower and examine it to see if it is crooked.
    Take off the blade and place it on top of a brand new blade for the RYOBI mower. The easiest approach to determine whether or not your blade has been bent is to check it in this manner. Even a very minor bend in the blade might result in a poor cut.

    Under NO circumstances should you try to reuse a mower blade that has been bent. When you do this to the metal, it will become compromised and weaker as a result.

    While traveling at high speeds, the weaker section might potentially break off and get dislodged from the mower deck. This has the potential to injure or cause harm to any of the people, animals, or property in the region.

4. An electric mower manufactured by RYOBI with an incorrectly installed mower blade

You run the risk of causing damage to your RYOBI electric mower if you choose the wrong blade to use or if you do not install the blade correctly. Before you begin to use it, you need make sure that the blade was positioned such that the sail is facing upward.

Sails are the name given to the elevated sides of the blade, and they play a role in the generation of air flow that causes the grass to be tossed. If the blade is positioned in such a way that the sail is directed toward the ground, it is likely that the blade motor may sustain damage as a result.

Instead of being cut in a regular manner, the grass will be ripped and battered up by the blade, which will result in a lower total amount of grass being cut. It is possible for it to collide with raised areas of the ground, which might cause an impact to the blade in addition to likely causing damage to the engine. This scenario is possible.

5. The Blade of a RYOBI Electric Mower Is Not Tightly Fastened

If the blade is not securely attached, it won’t be able to spin, and your electric mower won’t be able to cut the grass because of this. If the blade is not securely attached, it won’t be able to spin. First, consult the operator’s manual to determine the necessary torque requirements for the blade bolt, and then proceed to tighten it in accordance with the guidelines provided in the manual.

6. Adjusting the Cutting Height on an Electric Lawnmower from RYOBI

If the deck of your mower is set too low, it may not be able to manage the quantity of grass that you have to cut without sacrificing the quality of the cut, which may lead to an uneven cut.

In order to prevent the engine from being overworked while mowing dense, tall grass, raise the cutting deck of the mower to a higher setting.

When the grass on your lawn is long or thick, you should twice or even treble cut it. To do this, first cut settings on the mower deck should be adjusted to their most aggressive position.

Reduce the height of the deck before each subsequent cutting operation until you have achieved the desired cut.

7. The mowing deck of a RYOBI electric mower gets clogged with grass and other debris

When the mower deck of your RYOBI electric mower becomes clogged with grass, the mower will not give you a clean cut. This is due to the fact that there is not enough room beneath your deck for the blade to generate the airflow required to make a nice, accurate cut.

The deck of the mower and the blade work in tandem to generate suction, which lifts the grass and allows the blade to more easily go through it, resulting in a more equal and clean cut.

As a result of having to spin the blade through the grass clippings that are beneath the deck, having a blocked mower deck may also cause your motor to wear down and require it to work harder.

Using a deck scraper or wire brush, clean the mower deck on a regular basis so that it does not get clogged with grass and dirt accumulation. Try to avoid mowing grass that is moist. When the grass is wet, it will clump together and adhere to the deck of your mower.

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

In order to get a decent cut, you need to adapt your ground speed to the circumstances in which you are cutting.

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

As you cut through thick, long, or damp grass with your lawn mower, you put it under a significant amount of strain. You will need to reduce your speed if you want your mower to be able to cope with the workload.

A faulty cut isn’t the only thing that might cause the motor to stop working; it can also be overloaded, which can do the same thing.

9. Lawn That Is Not Even

Examine the condition that your lawn has deteriorated into. If you use your Kobalt mower to cut your grass, the uneven topography of your lawn will be impossible for it to fix. It’s conceivable that you have ruts and bumps in the grass, which indicates that the surface of the lawn is no longer smooth and level. If this is the case, you should try to fix it as soon as possible.

Because of the tunnels that rats have dug through the yard, I have to roll the grass every spring once the snow has melted in order to make the lawn as flat as possible. Rats have been doing this for a long time. If I don’t do this, not only will the cut be uneven, but the mower will also be all over the place as it bounces about.

Examine your lawn to see if there is any maintenance that needs to be done in order to keep it level and in fantastic form. If there is, then you should get started right away. In the event that there is, you will be required to carry it out.
