Take A Photo Of Your Lawnmower Service Ticket
Take a look around your lawnmower deck. It should have a rectangular service ticket on with all the details of your lawnmower.
This ticket gives you the exact code for your lawnmower plus the manufacturers name and manufacturers date of production. Take a photo of the ticket with a digital camera or mobile phone and make a back up of it.
User manuals tend to go missing and if the service ticket gets damaged with fuel or fades over time you will have a difficult time locating spare parts.

Is It Safe To Use Synthetic Oil In Lawn Mowers
Even though many mowers do come with the type of synthetic oil that allows you to use it, you must have the permission of your lawn mower manufacturer to use it. Synthetic oil is classified as synthetic and as a gasoline additive.
This means that you can never run your engine on synthetic oil. Your engine will only run efficiently on the type of oil that is designed specifically for your lawn mower, and that oil is not an approved synthetic oil.
Does it make the engine run better? No. It actually makes it worse. The engine that runs on synthetic oil is only designed for a petroleum-based engine. You cant use an engine that is made of something else. What is synthetic oil used for?

How Often Should Lawn Mower Blades Be Sharpened
How often you sharpen your lawn mower blades depends on how often you use them. The rule of thumb is to sharpen your blades when you notice a decrease in cutting performance. Sharpening mower blades once a year is good enough for some homeowners. Other experts recommend sharpening your blades at the start and around the middle of the mowing season. But you may need to sharpen your blades more often if you mow over debris, such as rocks or sticks.

Clean The Cooling Fins
Im often asked by my youtube subscribers why does my lawnmower cut out after a few minutes when it gets hot.
Most lawnmowers have cooling fins on and with poor maintenance, they all become clogged.
Remove the starter recoil cover and take a look around at the cooling fins. Remove any dirt with a stiff brush or an air compressor.
When engines overheat they stop working. Having clogged cooling fins causes this to happen a lot.
Change Lawn Mower Oil
To ensure it performs up to its maximum capacity, make sure you change lawn mower oil at regular intervals. Old oil that is black or contains debris should be drained and replaced. This will improve performance, reduce costly repairs and extend engine life of gas lawn mowers. A push mower has an oil capacity of 15 to 18 ounces. It should be changed either every 50 hours or annually, whichever comes first. A riding mower has an oil capacity of 48 to 64 ounces. It should be changed either every 100 hours or annually, whichever comes first.
- Before changing the oil in the lawn mower, disconnect the spark plug.
- Remove the drain plug underneath the mower and allow it to drain into an oil-safe container.
- If the mower does not have a drain plug, use an oil extractor kit to remove oil from the compartment.
- Add new small engine oil to the compartment up to the dipstick fill line. Oil formulated for small engines will keep your mower running at its best.
- Be sure to recycle the old oil properly.

Check The Blade Balance
Mowers run smoothest when the blade is balanced. However, sharpening sometimes removes more metal from one edge than another. This makes the blade unbalanced.
Its important to fix a blade that was imbalanced during sharpening. If it wobbles now, it will wobble on your mower too. An unbalanced blade may damage your mower. The vibrations alone are annoying, but the bearings or blade shaft might actually get destroyed.
Follow these steps to check the balance on your sharpened lawn mower blade:
- Support the blade under its center, like a scale. A screwdriver is an easy tool to use. Insert the screwdriver tip through the hole in the blade. The blade should balance on the tip or drop to balance on the handle.
- Hold the blade horizontal, then let go. It should remain level.
- If the blade drops in either direction, it means that the blade is unbalanced.
- The side that dipped down is heavier. Take a few strokes off that end to remove some metal, then retest.
For more precision in judging blade balance, purchase a blade balancer. Its a good addition to your mower maintenance tool kit. Its a cone-shaped tool that has a spindle for the blade.
