Tips For Maintaining Your Lawn Mower
Now that we’ve taken a look at how often you should sharpen your lawn mower blades, we can move on to discuss some tips for maintaining your lawn mower.
Follow the steps below, and you’ll be on your way to the best lawn mowing experience possible.
1. Make Sure To Change The Oil
One of the best and first tips we could provide you with when it comes to lawn mower maintenance is to make sure to change the oil at regular intervals. Make sure that at the end of each season, towards winter, that you’re draining the oil tank.
Sometimes, you might be required to change the oil more frequently, but this is only if it’s showing signs that it’s becoming viscous or contaminated. In this case, make sure to change it as soon as possible.
2. Clear Out The Mowing Deck
This is a tip that every long-time user would give you. Make sure that every time you’re finished mowing, that you clean out the mowing deck before the next use.
This is because when you’re using it, all kinds of debris, grass, and dirt will get stuck in the mowing deck, which is found in the area located just above the blades.
Make sure of course, that before you attempt to do this that you disconnect the spark plug to avoid any accidents.
3. Replace Air Filter
Another tip that we’d give you in order to maintain your lawn mower is to make sure that you’re replacing the air filter at the end of every season too.
This is something that many people forget about when it comes to lawn mower maintenance, but it’s a necessary step.
Over time, the air filter can get clogged up, and this makes it significantly harder for your lawn mower to do its job. You’ll notice that after you’ve replaced the air filter, that it runs far more smoothly and efficiently.
4. Maintain Your Tires
After every lawn mower use, you should be making sure that your tires are in ship shape. This means examining them, and taking care to check that there aren’t any dents or chips.
If you do have any of the above, this can impact the performance of your lawnmower.
You might find that it’s more difficult to maneuver around, so it’s important to check if they need replacing.
To sum up, when it comes to maintaining your lawn mower blades, you should seek to sharpen them after every 20 to 15 hours of usage time. Any more or less than this and you could risk them becoming dull.
In terms of general maintenance, you should always make sure that you’re replacing the air filter, checking the tires, replacing the oil, and clearing out the mowing deck.
This will make sure that it runs as smoothly as possible.
