Greasing a Lawnmower Spindles, Step-by-Step:

The spindles are located on the mower deck of a riding lawnmower. Before they can be greased, the mower deck must be removed. The steps for the entire procedure are listed below:

Gather your supplies:

Before we move any further, let’s list some of the tools you’ll need for the job. You shall need:

  • A grease gun with a grease cartridge
  • Wrench set
  • Screwdriver
  • Cotton rag

It won’t take much time with all the equipment at your disposal, provided you follow the steps correctly.

● Step 1: Perform initial steps

To start, you must perform preliminary steps on the lawnmower before removing the mower deck. These steps are:

– Remove the ignition key and spark plug cable:

Ensure the ignition key is removed and the spark plug wire is disconnected. This prevents an unintentional engine start when working on or close to moving parts. This step always needs to be done whenever you repair your lawnmowers.

Understanding the importance of greasing a lawnmower spindle is fundamental to maintaining your equipment. In my 20 years of experience, I’ve seen how regular greasing reduces friction, prevents wear and tear, and significantly extends the mower's lifespan.

– Engage the parking brakes:

It is better to perform the repairs on a flat floor, such as that of your driveway, as the screws and other small items are more accessible to locate when fallen. Also, engage the parking brakes of your mower.

● Step 2: Detach the mower deck

In the next step, we shall remove the mower deck to perform the greasing efficiently. This step is a little technical, so it is better to follow all the steps mentioned. If you are familiar with performing deck removal, you can move directly to step 3.

– Lower the mower deck:

Before its removal, the mower deck should be lowered to the ground entirely. This lowering is done by pushing the lever for the mower deck’s level adjustment.

The lever is usually present above the left rear wheel. However, before you lower the deck, you need to pull the blade engagement lever so the blades aren’t connected to the ground.

– Remove the belt from the engine pulley:

The belt that connects the idler pulleys to the engine pulley should be removed from the engine pulley and the belt keepers. It would be best to roll the belt out of the engine pulley to perform this step.

 The following parts/linkages need to come off to ensure the deck is entirely separated from the mower.

– Lift link supports at the front:

The deck is secured to the mower frame using various brackets and links. At the front, these links are called lift links. To detach them, you need to unscrew the nuts that secure the link in its place.

– Suspension arms:

The suspension arms connect the deck’s center to the frame. They can be detached by pulling their retaining pins and washers out. Make sure you disconnect the arms from the mower deck’s right and left sides.

– Rear deck bracket:

Much like the lift links at the front, the rear deck brackets connect the deck from the back end to the mower’s frame. Pull them off by removing their clamps and retaining pins.

With all these mechanical connections removed, your deck can be separated from the mower’s frame. Slide it out from underneath the mower’s frame.

● Step 3: Grease the spindles

Now, we come to the most critical step you tuned into this article: greasing the spindle assemblies.

The frequency of greasing a lawnmower spindle can vary, but a good rule of thumb I’ve followed in my two decades in the field is to grease the spindle after every 25 hours of mowing time, or at least once a year.

– Locate the spindles and remove their casings:

With the mower deck separated and right in front of you, tilt slightly to see how many blades and their respective spindles are visible below. This step gives you an indication of where the spindles that need to be greased are located.

Once identified, remove any plastic cover or casing to visualize the grease fitting on a spindle assembly. Use an appropriate wrench or a screwdriver to pull the plastic cover out.

– Load the grease gun:

A grease gun helps you perform this procedure with considerable ease. Along with the grease, purchase a suitable grease cartridge. You can find some information regarding the grease type in your lawnmower’s manual. Both the cartridge and the gun can be bought from a hardware store.

The steps for loading the grease gun are mentioned below:

  • Step 1: Detach the gun’s barrel: Take the gun and rotate its barrel anti-clockwise to remove it from the head.
  • Step 2: Pull the plunger back: Pull the plunger of your barrel back to its lowest position.
  • Step 3: Insert the cartridge correctly: Insert the cartridge into the barrel so the plastic side points downward. This prevents the formation of air bubbles. The cap side is facing upwards. Now, remove the cap securing the cartridge by pulling its handle.
  • Step 4: Connect the gun’s head: Connect the gun’s head back to the barrel, ensuring that it’s tightly fit. Also, push the follower rod of the plunger back to the top.

The grease gun is now loaded with grease, which can be pumped from its nozzle. A hands-on demonstration can be seen from this video:

– Connect the gun with the grease fitting:

The gun’s hose has a nozzle that should connect to the grease fitting on a spindle. Attach the nozzle to the fitting and pump the grease by pressing its lever.

Keep pumping the grease until you see some grease coming out of it. This means that the grease has been pumped entirely into the spindle assembly.

Wipe this extra grease that has come out of the spindle assembly. Repeat the same procedure on the other spindle assembly as well. If it’s the first time greasing the spindles on the lawnmower, it will take many pumps (typically 50) to lubricate the spindle thoroughly.

● Step 4: Reattach the various parts and test the mower

When the spindles have been greased, you can reattach the multiple parts and push the lawnmower.

Related Questions:

Choosing the right type of grease is crucial. Over the years, I’ve found that high-quality lithium-based grease is often the best choice for lawnmower spindles due to its excellent resistance to heat and moisture.

1. What is the best grease for lawnmower spindles?

Some of the users’ most recommended picks for the best grease for lawnmower spindles are listed below:

  • Valvoline – VV985 Full Synthetic Grease
  • Lucas Oil Products Red ‘N’ Tacky Grease
  • John Deere Original Equipment Grease
  • Mobil 1 MOBIL GREASE XHP 222
  • Wolf’s Head Red Grease Tubes

2. How often should you grease mower spindles?

Spindles on a lawnmower should be greased regularly. Generally, the greasing is done once a month, depending on your usage. More usage causes more wear and tear on the moving parts.

For domestic use, they should be greased every month ideally. Commercial mowers operating hundreds of hours monthly must be lubricated more often.

3. How do you know if a lawnmower spindle is terrible?

If a lawnmower spindle needs greasing, it will make a sharp noise while rotating. If you hear the noise, it means you are too late.

Optimally, you do it before you hear the noise. If the spindle has bent due to fatigue or an impact with a hard object, it causes the cutting blades to wobble at their pivot and make a cracking noise. You may also notice the grass being cut in a disorganized fashion.

4. How long do lawnmower spindles last?

The average service life of lawnmower spindles is about 2-3 years, depending on your use case. After that, they might get bent slightly, and the fatigue may also induce failure, thus affecting the cutting performance.


Greasing lawnmower spindles is relatively easy and can be performed in less than an hour, provided all the equipment and tools are available. It would be best to grease your mower’s spindles once or twice every season to guarantee a smooth operation.

It also reduces the maintenance that needs to be carried out on the blades and the mower deck. You can save a lot of money if you know how to perform this greasing yourself. Just ensure all the tools are available and you follow the safety precautions.

Firstly, you will need to give some time to understand the order in which the tasks must be performed. It might seem not easy initially, but it becomes a routine task once you get the hang of it. The spindles are sear the blades and require a grease gun for lubrication.

• Role of the Grease Gun in Reducing Friction

This is an essential part of the maintenance of the lawn mower. The weapon for the lawn is not a complex tool and can be easily operated. Using the grease gun for the spindles helps reduce friction and ‘increases the mower’s lifespan.

Whether you have a weapon for a lawn tractor or a push mower, the process remains the same. The grease gun for a lawnmower is a handy tool every mower owner should have. Storing the grease gun properly is essential when you are not using the grease gun.

Do not forget to clean it after every use. It is essential to stay clean, greasing the spindles. Always remember to clean the grease gun for the mower after every use. Before you start, you will need to gather all the necessary tools.

• Importance of Lubricating All Fittings

Lubricating all the fittings to ensure smooth operation is essential. Try to lubricate all the fittings at once to save time. Do not rush the process; take your time to grease the fittings in the right places.

It is recommended to lubricate fittings simultaneously to ensure even lubrication. This process will help extend the life of your mower and improve its performance.

Please pay special attention to the wheels of your mower, as they are in constant contact with the ground and can wear out quickly. Learning which grease to use for your specific mower model is essential.

– Choosing the Right Grease for Your Model

Different models might require different types of grease. Know which grease to use and how often to apply it. Remember, it is not just about applying the grease but also about knowing how to stay clean during the process.

Greasing can be messy, but you can keep your workspace and yourself clean with the right tools and techniques. So, next time you decide to grease the spindles and wheels of your lawn mower, keep these points in mind.
