Riding Lawn Mower Maintenance
If you want a reliable mower all season, and who doesn't? Then your Riding mower will need a tune-up at least once a year, preferable in the spring before the season starts.
So what is riding mower maintenance? To maintain a riding mower, the following components need attention:
- Full inspection
- Oil & filter change
- Air filter change
- Fuel filter change
- Spark plug change
- Axle lube
- Blade sharpen
- Tires pumped
- Deck align
- Throttle cable adjusted
At the very minimum the oil should be changed at the start of the season. If your mower is new, change the oil after the first 5 hours of use.
Some mowers will have a handy tune-up interval chart stuck under the hood or under the seat.

What Tune-up Parts Needed?
Id Your Engine
Knowing how to identify your mower engine is useful for parts ordering.
Inspection & Tune-up
If you can't find your oil filter, then you don't have one, so you can go ahead and skip this part.
Remove the old filter, you may need an oil filter tool, but their usually not that tight.
5 Fit Filter
When fitting the new filter, apply some oil to the o ring, it prevents distorting the seal when fitting.
Only tighten the filter - hand tight.
6 Add Oil
If your mower has an oil filter, then check the oil level again after you test run the engine.
This can be done at the end of the tune-up.
7 Check Levels
Add oil a little at a time, and check the level. Over filling is not good for the engine.
It will cause oil leaks, misfiring and lots of smoke.
All controls and levers will benefit from a spray of WD40.
Check rear axle oil level. The front Axle will have greasing points, for this you'll need a grease gun.
Be sure to use an axle stand or block of wood to secure the mower as you'll be working under it.
Don't take any chances. Check out the tools on the blade maintenance page.
If your not comfortable working under your mower, then remove the deck.
Some decks will be pretty simple to remove.
Removing Deck blades for sharpening and balancing is best practice. Inspect the blades for damage, replace if bent cracked or worn.
If the blades are in good condition, you can sharpen them in place.
Sharpening your blade is done with a good quality flat metal file.
Begin by dressing the face of the blade to remove any small nicks.
Now dress the opposite side to remove the burrs.
A sharp blade is the secret to a beautiful healthy lawn, and it extends the life of your mower.
Check the condition of the belts. Most mowers have at least two belts, one for driving the mower and one for driving the blades.
Some mowers will have more.
These belts have a difficult job and can be the cause of various issues.
Regular inspection will tell you if your belt is at the end of its life.
Worn or damaged belts cause slip, which in turn will cause vibration.
The vibration can if ignored go on to cause lots of other issues.
Decks tend to drop at the front over time. Place the mower on level ground.
Measure the height of the four corners of your cutting deck.
Let your deck down approx. half way. Now measure the height of the four corners of your cutting deck.
Note the highest corner, and adjust all other corners up, so they match.
You'll find adjusters at each corner, they'll have a lock nut that will need to be released first.
Turning these bolts adjusts the deck up and down. Spray with WD40 - makes life a little easier.
Decks that sag will impact your lawn causing damage to your blades and your lawn.

Should I run my lawn mower out of gas for winter? No, it is best to use a gas stabilizer, it keeps the gas fresh and will protect your fuel system. Running the gas out of the mower doesn't prevent gumming of the carburetor over winter.
Can you store a lawn mower vertically? A lawn mower should be stored on its wheels, however if you drain the oil and gas from the engine you can store it in any position you like.
