Lawn mower owners need to know how to maintain the machine’s small engine. Therefore, you need to be able to keep the engine well-lubricated. In fact, engine lubrication plays an essential role in ensuring engine performance and longevity.
A Reduced Oil Pick-up Point
The oil that is used in a mower’s engine reduces the engine temperature as well as friction between the parts. Most well-built lawn mower engines are designed with a reduced oil pick-up point. This feature safeguards the engine against wear when it is operating at an angle or is running low on oil.
Consult Your Operator’s Manual First
The importance of engine maintenance cannot be overstated. That is why you need to stock up on engine lubricant products and refills for your grease gun. Before you perform any grease or lubrication work, consult your operator’s manual first. Manuals cover lubrication maintenance for riding and push mowers. Normally, if you locate the manual online, you will need to enter the model engine number to access the information.
Locating a Mower’s Model Number
The engine model number normally appears, stamped, above the spark plug, on the front of the engine, or above the muffler. Once you obtain the number, you can review your maintenance manual to locate the fittings that need to be regularly greased.
Learn Which Grease to Use and how to Stay clean Greasing!
Make Sure You Use a Grease Recommended by the Mower’s Manufacturer
One of the biggest mistakes that lawn mower owners make is using the wrong type of grease. The brand of the grease does not matter as long as you use the grease advised by the manufacturer. Grease may contain lithium with molybdenum disulfide or be made up of plain lithium. Poly urea, a type of elastomer and protective coating, is another ingredient that is used in the product. Greasing is important as it enables parts to resist abrasion, provides corrosion protection, and adds waterproofing resistance as well.
Grease Each Fitting Whenever You Change the Oil
Every fitting should be greased each time you change the oil. Again, the owner’s manual should assist you in locating all of the mower’s fittings. In addition, an adaptable hose can make reaching the lawn mower fittings much easier. A grease gun and hose can be purchased at any auto parts dealer or home center store.
When Should the Oil be Changed?
Typically, the oil should be changed in the fall, or at the end of lawn-mowing season. By changing the oil at this time, you can extend the life of the engine and mower. Fresh oil contains rust inhibitors, which lengthen a mower’s life. If you do not change the oil at the end of the season, deposits will settle in the engine during the off-season. Changing the oil should be a part of your lawn mower storage preparation for the winter months ahead.
How to Facilitate the Greasing Process
Begin greasing by turning the head of the grease gun counterclockwise in order to unscrew and pull it off. Then, pull the plunger rod at the bottom of the gun’s barrel from the gun. Push down the release latch to lock the plunger. Next, you need to pull the plastic tables off either end of a No.2 all-purpose cartridge of grease, inserting it at the top of gun’s barrel. Follow by replacing the head and releasing the latch. Press the grease gun coupler onto the zerk fitting and gently press the handle to begin the grease flow.
Greasing the Spindles: A Basic Primer
When greasing your lawn mower, park the machine on a solid and flat service, such as the driveway. Turn off the ignition and permit the mower to cool down for about ten minutes. Lower the deck of the mower to its lowest setting. That way, you can access the grease fittings much easier. Utilize a lever-action type gun for lubrication.
The spindles that need to be lubricated include the cutting spindles and front axle spindles. The grease fittings are situated on the back of the spindle. The front axle spindles are easy to locate and access. They can be found on the rear side of the left and right front axle spindles.
Begin by Greasing the Cutting Spindles
Locate each of the zerk fittings on the mower’s cutting spindles. The mower features a spindle for each blade. Zerk metal fittings are located on the fronts of spindles and look nipple-shaped.
Remove any debris, grease, or dust with a cloth on each zerk fitting. Insert the grease gun’s tip over each zerk fitting and press downward. While holding the barrel of the grease gun with one hand, push the plunger gradually inward in order to fill each joint with grease. When the grease flows out of a fitting, it is considered full. Pull off the gun tip off the fitting, then wipe away the excess grease. Repeat the process on each spindle.
Lubricating the Front Axle Pivot Fitting
You also need to lubricate the front axle pivot. This part is located in the center of the assembly of the front axle. The fitting can be difficult to see unless you get on your back and view it by looking up under the mower’s front end. Use one or two pumps of grease until you see a small amount of grease emerge from the fitting.
Lubricating the Deck Lift Pedal
This fitting is situated at the base of the mower’s deck lift panel. Again, use one or two pumps of grease until a small amount of grease squirts from the fitting.
What You Should Do before Storing the Gun
You will need to wipe any excess grease off the grease gun’s tip before storing it. By taking this measure, you can preserve the grease cartridge for further use.
Lubricate All the Fittings at the Same Time
Again, you need to refer to your owner’s manual to find all the fittings for your specific lawn mower’s make and model. You should always lubricate all the fittings at the same time.
Keep You Mower Clean
When you use a riding mower, clean the deck after you use it. Spray the mower on each side with a garden hose. When you make cleaning a practice, you lessen the chance of fire and also prevent rusting of the deck.
Change the Oil and Lubricate Your Mower Regularly
Once more, you should maintain your lawn mower in accordance with the manufacturer’s recommendations. Changing the oil and oil filters, and lubricating your mower will keep the machine performing just like the day you first bought it.
