How to Grease a John Deere Lawnmower, step by step


John Deere is one of the more popular lawnmower brands with good quality products. To keep your mower working well, you need to give it regular maintenance. Regular maintenance ensures that the lawnmower keeps its power, speed, and smoothness. New owners of John Deere and other lawnmower brands are usually not aware of the different maintenance routines that are required. To keep the smoothness of your lawnmower you need to lubricate the moving parts regularly. This improves the wear and tear resistance and makes the machine last longer. Engine oil takes care of the lubrication of internal parts, but axles and wheels and spindles on the deck, etc., have to be greased manually. In this article, we will show you how to grease your John Deere lawnmower.

How to Grease a John Deere Lawnmower:

Two main components of a John Deere mower that require periodic greasing are the front axle and wheels, and the spindles and mower deck. Check and greasing is a simple job. It should be done every 25 hours and should not take more than 30 minutes. Other components that need some greasing include the deck lift pedal, lift arm, rock shaft, lift cylinders, driveshaft, and steering cylinder.

How to grease a John Deere Lawnmower front axle and the front wheels, step by step:

  • Step 1: Park your mower in an appropriate area with the parking brake applied.
  • Step 2: Locate the grease nipple directly underneath the middle of the axle. Put the end of the grease gun in the nipple and pump the handle to grease the axle.
  • Step 3: Locate the grease nipple on the inside of one of the front wheels. Put the end of the grease gun in the nipple and pump the handle to grease the wheel. Repeat the same procedure for the other wheel.
  • Step 4: Also, grease both the wheel shafts. Their grease nipples are located at the front of the shafts, directly beside the tires.

How to grease the John Deere Lawnmower spindles and mower deck, step by step:

  • Step 1: Park your mower.
  • Step 2: Lower the deck to the lowest setting.
  • Step 3: Locate the nipple on top of the blade brake pivot on the right side of the deck. Spray the pivot with an all-purpose lubrication spray. Repeat for the nipple on the left side of the deck.
  • Step 4: Locate the deck idler pivot point on the left side of the right-hand blade spindle. Spray this pivot point with an all-purpose lubrication spray.

We will discuss the greasing procedures for all these components in more detail in this blog.

Step by Step Procedure for Greasing a John Deere Lawnmower:

Before we start with the actual process of applying grease, let’s look into the type of grease that should be used. John Deere recommends grease for parts that are involved in high-speed movement and grease for other parts.

● The best Grease For High-Speed lawnmower parts:

For components of a John Deere lawnmower that are actively involved in high-speed movement, John Deere recommends the John Deere Multi-purpose SD Polyurea Grease or the John Deere Multi-purpose HD Lithium Complex Grease.

The high-speed parts for which these greases are recommended are:

  • The Mower Spindle
  • Bearings from the rear axle of the mower
  • Universal joints of the mechanical four-wheel driveshaft

● The best grease For Other lawnmower parts:

John Deere recommends the John Deere Multi-purpose HD Lithium Complex Grease or John Deere Moly High-Temperature EP Grease for the rock shaft, deck lift cylinders, and deck lift arms and tie rod, etc. These are the components of a John Deere lawnmower that are not directly involved in high-speed operations.

The manufacturer prefers the greases mentioned here. Other general-purpose greases with an NLGI grade 2 rating. Moreover, wet applications require special greases. Consult the user manual or the provider for further info on special greases.

Let’s start with the greasing procedure for a John Deere Lawnmower’s different components with the right grease arranged.

● Greasing the John Deere Lawnmower Front Axle and Front Wheels:

Follow the steps given below to grease the front axle and front wheels:

– Step 1: Park the Mower

Park your John Deer mower in an open flat area. Use the parking brakes to ensure that the mower does not start rolling while greasing the different parts. Also, turn the wheels such that they are facing straight ahead.

– Step2: Grease the Front Axle

All components that require greasing have grease nipples where the grease can be added. All you need to do is find the nipple on each component and put the grease in it. The grease nipple of the front axle is located directly underneath its middle section. Put the end of the grease gun in the nipple and pump the gun’s handle until there is pressure in the handle. Then remove the end of the grease gun from the nipple.

– Step 3: Grease the Front Wheels

The grease nipple is located on the inside of each wheel. Locate the nipple, place the end of the grease gun in the nipple, and pump its handle. Remove the grease gun when you feel pressure in the handle. Perform this procedure for both front wheels.

– Step 4: Grease the Front Wheel Shaft

The final step is to grease the nipples located at the front of both wheel shafts located just beside the tires. Put the end of the grease gun in the nipple and pump the handle until grease starts coming out of the bushing. Perform this procedure for both front-wheel shafts.

● Greasing the John Deere Lawnmower Mower Deck:

Follow the steps given below to grease the deck of your John Deere lawnmower:

– Step 1: Lower the Mower Deck

Lower the deck of your John Deere mower to the lowest setting.

– Step 2: Grease the Blade Brake Pivot

There are two brake blade pivot nipples, one on the deck’s right side and another on the left side. Spray the two-blade brake pivots with the grease recommended by the manufacturer or with an all-purpose grease.

– Step 3: Grease the Deck Idler Pivot

There is a deck idler pivot to the left of the right-hand blade spindle. Locate this pivot point and spray it with the grease recommended by the manufacturer or an all-purpose grease.

● Greasing Other Components from a John Deere Lawnmower:

Follow the guidelines given below to grease other important components of your John Deere lawnmower:

– Mower Lift Arms, Lift Cylinders, and Rockshaft:

Park the mower with the parking brakes applied. Lower the deck completely. Locate the lift arm pivot joint and the rock shaft pivot joint of the front deck. Spray these pivot joints with the John Deere Moly High-Temperature EP grease or the John Deere HD Lithium Complex Grease.

Repeat this procedure for the side deck lift arm pivot joint and lift cylinder pivot joint on both sides of the lawnmower. Use the same grease as mentioned above for these pivot joints too.

– Rear Axle Pivot Point and Rear Tie Rod:

There is a grease fitting/nipple on the left side of the rear axle. Locate this fitting and grease it with the John Deere Moly High-Temperature EP Grease or the John Deere HD Lithium Complex Grease.

Once done with greasing the rear axle pivot point, grease both ends of the rear tie rod with the same greases as mentioned above.

– Drive Shaft:

you should completely lift the mower deck to grease the drive shaft. Once the mower deck is lifted, engage both side deck transport locks. Then grease the front and rear universal joints of the drive shaft with the John Deere Multi-purpose SP Polyurea Grease or the John Deere HD Lithium Complex Grease.

– Hydraulic Steering Cylinder:

The hydraulic steering cylinder is located at the rear of a John Deere lawnmower. Find the steering cylinder and spray both ends with the John Deere Moly High-Temperature EP grease or the John Deere HD Lithium Complex Grease.

● Things to Keep in Mind:

If you intend to grease your John Deere lawnmower, keep the following important things in mind:

  • Clean before: Clean the grease fittings/nipple before and after applying the grease with a rug. This is to prevent contamination.
  • Temperature and moisture: The greases recommended by the provider are most effective in a certain range of temperature and moisture. You don’t need to worry too much about the temperature part because the temperature range is, for most grease, pretty wide (-22 to 275 F). Anyway, if you intend to work outside the prescribed ranges, especially for moisture, consult your service provider for special-use lubricants.
  • Use different grease types: Always use the right grease for the right part. A general-purpose grease is generally not recommended for high-speed applications.
  • Check the manual: The grease fittings/nipple may be located at different locations in different models. For the most accurate location of all grease fittings, consult the manufacturer’s manual or your service provider.

● When and how often to Grease a Lawnmower:

Greasing is an important maintenance routine. The thin layer of lubricant between moving parts considerably reduces friction. Reduced friction means reduced machine heating, smooth operation, and less wear and tear. Thus regular greasing enhances the performance and service life of a John Deere lawnmower.

We recommend you thoroughly grease your John Deere lawnmower every 25 hours of operation. 

Final Remarks:

Proper lubrication is extremely necessary for moving parts of all machines, and your good quality John Deere mower is no exception to this rule. Get the recommended John Deere greases and grease your mower yourself. The greasing procedure is very simple and can be completed in 20 minutes at the most. The guidelines provided in this blog post will help you through the procedure. Regular greasing will ensure that your mower works smoothly and lives longer.
