  1. Fix The Wheel By Using A Copper Pipe

It’s a very simple but effective trick to fix wobbly wheels.

Required Tools and Material

  • Standard copper plumbing pipe

  • Pipe cutter

  •  A drill machine

  • A marker

Fixing process

To begin, you will require a standard copper plumbing pipe, which has a width of approximately one half of an inch.

Take the wheel off the lawn mower and set it aside. You can remove the screw that is keeping the wheel attached to the lawn mower by using a drill machine. This screw is what is keeping the wheel attached. You should be able to see an axle once the wheel has been removed.

Position the axle so that it fits inside the copper pipe. At that point, the copper pipe ought to be able to slide in and out of the axle with relative ease. In the event that it does not work, you might have to switch to a different girth of copper pipe. Keep in mind that the copper pipe should not be mounted on the axle in such a way that it is either too tight or too loose.

Next, make a mark on the shoulder of the axle that corresponds to the length of the copper piper. Check to see that their lengths are comparable.

Use a pipe cutter to make the cut in the pipe. It will make a very clean cut through the pipe. You could also cut the pipe with a hacksaw if you prefer. However, this will result in the pipe edges becoming more jagged. Sandpaper should be used to smooth any sharp edges on the pipe before it is put to use.

The next thing that needs to be done is to insert the piece of the copper pipe that has been cut into the hole in the wheel. There is no need to be concerned if the hole appears to be smaller than the copper piece.

Make the hole slightly larger with the drill machine so that the piece of copper pipe can fit through it. It is important that the pipe is securely inserted into the hole.

Because copper is a soft metal, you shouldn't use a hammer to try to force the copper pipe into the hole of the wheel; rather, you should use a brass hammer or a wood block, both of which won't break the pipe.

The very last thing you need to do is insert the wheel into the axle, and then fasten the wheel's screws.

To fix the wobbly wheel on your lawn mower, all you will need to do is the aforementioned thing.

2 .Tighten the Bolt

Before jumping into any conclusion about your wobbly wheel, it is better to check the bolt of your wheel. It could have simply loosened over time. Tightening the bolt will easily solve your problem.

Required Tools

  •  Socket wrench

Fixing process 

  • To do this, first remove the spark plug as a safety measure to avoid any accidents. 

  • Then use a socket wrench to locate the bolt of the loose wheel. 

  • Lastly, tight the bolt. Make sure that the wheel is not too tight, as it can create problems while the lawn mower is running.

3. Using a Spacer

This is another easy method with minimum cost to solve the wobbly wheel problem. But for this, you will need a spacer which is the same in size as the bolt of the lawn mower’s wheel. 

Required Tools and materials 

  • Spacer

  • Hammer

  • Socket Wrench

  • Lubricant

Fixing Process

 

The spacer, which is typically made of aluminum and is inserted into the tire using nuts and a caster bush, provides additional clearance. Caster bush is typically used for connecting axles and other sections of the chassis to the various pivot points and moving arms. Caster bush can also be used in some other applications.

After locating a spacer that works perfectly, the next step is to remove the wheel's loose axle so the spacer can be installed.

The hole in which the old wheel axle was should then be reduced in size using a file.

The next step is to use a hammer to secure the spacer into the hole once it has been drilled.

After removing any rust from the old axle, the axle can then be reinstalled into the wheel with the help of the spacer. To make the axle and spacer as smooth as possible, you may use oil as a lubricant.

In the final step, reattach the wheel to the lawn mower by using a socket wrench to ensure a secure fit.

4. Replacing the Wheel

The last resort is to swap out the worn-out rim. This method isn't necessary if you see any physical damage to the wheel, in which case a replacement is the only option.
As a safety precaution, always remove the spark plug before beginning any repair work.
 

Why Do The Wheels Of The Lawn Mower Get Wobbly?

The vibrations produced by the lawn mower's engine typically cause the front wheels of the lawn mower to become looser than the rear wheels more quickly. This vibration, over time, causes the bolts that hold the wheels to become more loosened.
There is also the possibility that the surface of your lawn is not perfectly smooth and even. This would be another explanation. Mowing on uneven or bumpy terrain can cause the wheels to become loose or wobbly, depending on the severity of the terrain.
 

Low Wheels Or High Wheels To Avoid Wobbly?


Around 8 inches is the standard measurement for the medium-sized wheels found on lawn mowers. On the other hand, there are wheels available on the market that range somewhere between 9 and 12 inches in diameter. The question now is: how do you decide which option to go with?
The response to that question is quite simple. Choose an option that is closer to 12 inches in height if your lawn is rutted, has any uneven areas, or steep hills.
Wheels with a smaller diameter typically follow curved areas with a greater degree of precision than those with larger diameters. As a consequence of this, the deck of the lawn mower has a chance of being struck by the object, which will ultimately result in the lawn being damaged.
On the other hand, if you have a small lawn that is level, you can get away with using wheels that are either small or medium in size. However, larger wheels are typically more expensive than the smaller ones, so unless you absolutely need them, you shouldn't go with the larger option unless it's absolutely necessary.
