Why does my edger vibration? Repairing an Edger That Vibrates

Your edger has a built-in vibrator, but why does it sometimes stop working? Is it time to replace it?

Edgers are tools designed to trim grass or weeds around flower beds and shrubs. They come in two types: handheld and motorized. The handheld version requires manual operation and uses a rotating blade to cut grass and weeds. Motorized edgers use a powerful electric motor to rotate blades at high speeds.

You should change the battery regularly because they wear out over time. If you notice that your edger stops working, check its condition before replacing it. You can do this by following these steps:

  • 1. Turn off the power switch on the back of the unit.
  • 2. Remove the cover from the top of the machine.
  • 3. Check the belt for cracks or damage.
  • 4. Look for any loose parts.
  • 5. Make sure the blade is sharp.
  • 6. Clean the area where the blade will be used.
  • 7. Replace the blade if necessary.
  • 8. Reattach the cover and turn on the power switch.
  • 9. Test the edger again to make sure it works properly.
  • 10. Use the edger as needed.

Why does my edger vibration?

If your edger doesn’t work properly, there could be several reasons. One reason may be that the blade isn’t sharp enough. Another possibility is that the blade is worn out. A third possible cause is that the motor is not turning fast enough. 

In addition, some people have reported problems with their edgers when using them near water. This problem occurs when the edger creates suction while cutting through wet soil. To avoid this issue, try to keep the ground dry whenever possible.

How often should I replace my edger’s blade?

The best way to determine how long your edger blade needs to be replaced is to measure it. Blades vary in length depending on what type of edging you want to perform. For example, a 6-inch blade is usually sufficient for edging flower beds. However, an 8-inch blade is recommended for edging large areas such as lawns.

To find the correct size blade for your edger, follow these steps:

  • 1. Measure the width of your garden bed.
  • 2. Determine how many inches wide you need to edge the entire bed.
  • 3. Multiply the number of inches by the height of the bed (usually 4 feet).
  • 4. Divide the result by 12 to get the total number of inches required per year.
  • 5. Add 2 inches to account for growth.
  • 6. Subtract 1 inch to allow for maintenance.
  • 7. Round up to the nearest whole number.

For example, if you need an edger blade that is 6 inches wide, multiply 6 x 4 24 inches. Then divide 24 by 12 to get 3.33. Add 2 inches to get 5 inches. Subtract 1/12th inch to get 4 inches. Rounding up gives us 5 inches.

How To Repair Edger With Excess Vibration

When your edger vibrates excessively, check the bearings, blades, supports, rods, belt, springs, and coupling. Find out how to replace your part and solve your problem with our repair and symptom guide. Detailed information about your model can be found in the owner’s manual. This is a general guide for your repair.

Extensions and adapters

It is possible to add adapters and extensions to some edger models. It is common for these types of additions to be screwed or bolted on, so they can occasionally come loose.

You may be able to stop the vibration by tightening the bolts and/or screws on an adapter or extension that has been incorrectly installed or has simply become loose over time. It is possible that one or more of the bolts/screws have become loose and fallen off, in which case they will need to be replaced.


Your edger’s bearings prevent moving parts from grinding against one another. As a result, your edger will not seize or lock up. It is possible for the bearing to become worn over time, and when this occurs, they can seize up. Vibration can be caused by a worn bearing on anything that rotates. To relieve this symptom, it is important to determine which bearing is worn and then replace it.


Drive belts and other belts may be used by your edger to help it run efficiently. Rubber belts tend to be flexible, yet rigid enough to maintain a somewhat consistent shape, and are usually made of rubber. It is possible for your machine to rumble, shake, or vibrate if the rubber of the belt becomes stretched.

Additionally, these belts run on pulleys, and if these pulleys are not aligned properly, your edger will vibrate. Vibrations can be eliminated by adjusting a misaligned pulley system. For this symptom to be resolved, a stretched belt will need to be replaced.

The blades

You may encounter rough terrain, rocks, and other debris while operating your edger. The blade can bend if it strikes something hard enough. As a result, the blade may not spin straight and true. As a result, it may rub against the blade cover and cause excessive vibrations.

You may be able to bend the edger blade back to its original position by using a wrench or vice grips, depending on the type of edger you’re using. When your edger blade bends too much, it can snap, which can cause more damage to your edger as well as pose a safety hazard. The blade should be replaced if it is badly bent or damaged.

The springs

In your edger, springs hold different parts in place by providing tension. It is possible for the springs to wear out and lose their tension over time. They can ratchet and vibrate the parts they are trying to hold in place as a result.

This can lead to excessive vibration when operating your edger, resulting in decreased performance. When the spring breaks completely, you’ll need to replace it, not only to prevent vibration but also to prevent other parts from breaking.

The rods

Between the piston and the crank shaft in your edger’s engine are connecting rods. In this way, combustion energy is transferred to the crank shaft, which powers your machine. In some cases, this connecting rod can become worn or loose, causing it to rattle around within the crankcase.

While the edger is operating, excessive vibration and noise can be generated. This symptom may be resolved by simply tightening the connecting rod. Engine failure may also occur if the rod is damaged. Before your edger stops vibrating, you will need to replace the rod.


There may be several supports on your edger designed to keep other parts in their proper place. Support may be in place to prevent the engine from moving. The function of these supports can be compromised if they are broken, worn, or lost.

Some engine supports can be secured back into place by simply tightening one or more bolts. When a bolt is missing, you must replace it before the vibration stops. This symptom will also be resolved if the support itself is damaged.


In your edger, couplings connect two shafts. It is possible for these couplings to become out of round or incapable of retaining their circular shape at times. Couplings can bend or wear down over time as a result of bending or wear.

In this case, the shafts connected at the coupling will not be able to spin smoothly, resulting in vibrations. If your edger coupling is worn out or damaged, it will need to be replaced, as it will cause further damage and loss of performance.

How do you tighten edger blade?

To tighten an edger blade, loosen the screw on the back side of the blade holder (the one with the handle). Then turn the screw counterclockwise until the blade tightens up. Tighten the screws slowly so they don’t strip out any threads.

Can you put a saw blade on a edger?

Yes, it can be done with a hacksaw blade. You will need to make sure that there are no obstructions between the blade and the edge of the blade.

How do you edge a stick edger lawn?

You can use a hand edger to edge a stick edger. To get started, first cut off the top part of the stick. Next, insert the blade into the hole where the handle would normally go. Finally, push the blade through the grass and pull it back out. Repeat this process until the entire stick has been edged.

How do I make my lawn edges sharp?

Sharpening blades is easy! First, remove the blade from the edger. Next, sharpen the blade on a whetstone using a medium-to-fine grit stone. For best results, sharpen the blade while it is still attached to the edger. After sharpening, clean the blade with water and let it dry.

Do manual edgers work well?

Manual edgers are great for small areas such as flower beds, walkways, etc. They are also good for trimming trees and shrubs. Manual edgers are less expensive than electric ones. However, they require a lot of maintenance.

How often should I edge my lawn?

Edging your lawn every three weeks is recommended. Edging too frequently can lead to weeds growing in your lawn. Also, when you have a large area to edge, it takes longer to complete the job.
