How to Lubricate Lawn Mower Wheels

Maintaining your lawn mower is something that should be done on a regular basis, regardless of whether you run a landscaping business or just have a small patch of grass to cut. Lubricating the wheels of your mower can make a significant difference in a number of ways, including the prevention of smoke and an increase in the machine's overall lifespan.

To lubricate the wheels on a lawn mower, you must first remove them using a grease gun, and then repeat the process for the wheel bearings. The next step is to lubricate the spindles, and after that, you might want to consider using a dry graphite spray to get rid of the fine particles. If you want the best results, you should repeat this process twice a year.

Remove the Wheels

Did you know that one of the primary causes of smoke coming from an engine is wheels that are rusted and dull? Lubricating the wheels of your lawnmower is an important and essential part of maintaining it in good working order. It guarantees that the functionality of your machine will remain unchanged from the day you first purchased it.

Lubrication lowers the amount of friction that exists between the moving parts, which makes movement more efficient. Additionally, it protects the wheels from abrasion, corrosion, and an increase in their resistance to water.

Before you perform any lubrication work on your lawnmower, you must, however, consult the operator's manual to determine the type of grease that is recommended for use with your mower.

Manuals not only provide information on how to maintain your mower, but they also describe the different types of parts that are available for it. If you are looking for the user manual on the website, use the model engine number to gain access to the information you need.

When removing the wheel from your lawnmower, the following guidelines should be followed in order to avoid any accidents. Refer to the user manual provided by the manufacturer for specific instructions pertaining to the model of your mower.


Removing a Push Mower’s Wheels

  1. Begin by unplugging your power supply.

  2. Underneath the front edge, gently raise the mower and place a brick or plank of wood. Do the same for the rear wheels if you want to detach them.

  3. Using a hand or a screwdriver, detach the hubcap. If you miss a screw in the center of the wheel, the hubcap is probably covering it.

  4. Remove the center screw by rotating it anticlockwise by using a socket wrench.

  5. Using pliers or hands, remove the washer located under the screw if your mower has it.

Removing a Riding Mower’s Wheels

  1. Position the mower on a flat surface like the driveway. Carefully disconnect the power cord from the battery.

  2. Under the wheels you want to change, place the mower lifter. Apply pressure to the mower lifter until it makes a 90-degree angle with the ground, then lock the pins attached to the lifter.

  3. Using hand gloves, rotate the plastic cap mounted on the center of the wheel anticlockwise. Some mowers lack this cap.

  4. Remove the cotter pin using pliers or a screwdriver and remove the washer located underneath.

  5. Pull the washer outwards underneath the pin, and remove it.


Using a Grease Gun


According to Advanced Engine Tech, using a grease gun can completely change the way you clean your mower. To use a grease gun, follow these steps:

  1. To begin greasing, turn the head of the grease gun counterclockwise to unscrew and pull it off.

  2. Locate the plunger rod at the bottom of the barrel and pull it away from the gun.

  3. Lock the plunger by pushing down the release latch.

  4. Proceed to pull the plastic tables off each side of a No.2 all-purpose cartridge of grease and insert it at the top of the gun’s barrel, then replace the head and release the latch.

  5. Press the grease gun coupler onto the fitting and begin the grease flow by gently pressing the handle.


Lubricate the Wheel Bearings


If your mower has wheel bearings, you should make it a habit to lubricate them after every 25 hours of use to prevent the bearings from wearing out prematurely. Before beginning any kind of mower maintenance procedure, you should always go through the user manual and go over the safety instructions. It is made much simpler to apply grease to the internal bearings thanks to the zerks. First, using your grease gun, pump in some grease until you see a small amount of it coming out of the fitting. After that, wipe off any excess grease.



Grease the Spindles


The spindles are the posts to which the blades are attached and around which it spins during operation. Depending on the manufacturer of your lawnmower, it may have one or more spindles. The spindles that require lubrication include the cutting spindles and the front axle spindles. To apply it, try the following steps:

  1. Park the lawn mower on a hard, flat surface and turn off the ignition to allow the mower to cool down for about 10 minutes.

  2. Lower the mower deck to the lowest setting to permit you to access the grease fittings easily. The grease fittings are on the back of the spindles. The front axle spindles are the easiest to locate. The grease fittings are on the rear side of the left and right sides of the spindle.

  3. Locate each zerk fittings on the cutting spindles of the mower. For each spindle, there is a nipple-shaped zerk metal fitting on the front.

  4. Clean the zerk fittings of any dirt, debris, or grease using a clean cloth

  5. Use a lever-action gun for lubrication. Insert the gun tip over each zerk fitting and press downward. Refer to your user manual to understand where the grease gun goes in. 

  6. Proceed to push the plunger gradually inward to fill each joint with grease while holding the barrel with one hand.

  7. To effectively grease your spindles, fill up the grease until you see it come out on the other side of the spindle. A fitting is full when it overflows out of it.

  8. Pull off the tip of the gun, then use a rag to clean off the excess grease.

  9. Repeat this procedure on each spindle.


Use Dry Graphite Spray


Dry graphite can be used as a lubricant in places in mowers where there is a problem with dust and dirt. The reason for this is that it does not leave behind any sort of sticky residue that could potentially attract dust in the future.

For convenience in application, the graphite is mixed with solvents that evaporate quickly and then poured into a spray can for storage. This powdery graphite deposit is left behind after this liquid solvent quickly evaporates, and the area that was lubricated by it.

Additionally, dry graphite spray has a high resistance to both heat and pressure. When it comes to lawnmowers, making use of it is nothing more than a matter of convenience.


Investigate Additional Causes


Always ensure that you clean your mower thoroughly after each use to remove any dirt or debris that may have accumulated while you were mowing. Make use of a garden hose to spray each side of the deck of the lawn mower. It will protect the mower from damage, ensuring that it continues to function correctly and for a longer period of time.


Lubricate the Rest of the Mower


Lubricate the deck lift pedal along with the rest of the fittings on the mower at the same time. Other parts of the mower should also receive lubrication. If you keep your mower well-greased and in working order, it will have a much longer lifespan.



Perform the Process Regularly


Keeping up with mower maintenance is one of the most important things you can do to extend the life of your equipment. Alternate the oil and oil filters in your mower on a regular basis, and grease it twice throughout the mowing season. However, if you mow lawns for a living, you should do it more frequently than the average person.

As you can see, greasing the wheels on a lawn mower is a fairly straightforward process. To get started on the job, you will only require a few tools, and the entire process will take less than an hour to complete. Wear clothing that will protect you from the elements, and keep your hands away from your face until the task is completed.
