Here are some guidelines to resurrect your lawn mower along with other small equipment from their winter nap and get them ready for regular warm weather use. None of this is rocket science, but tried and tested steps that will make your mower run its best and provide you with the most years of service possible.
Take away the spark plug and switch the air conditioning filter
This is a provision, as you never want to do any type of use the engine or a sharp blade without disabling the power supply in the equipment.
Your mower requires a clean air filter every season. If the filter is one of the foam variety, fix it. If you have a more affordable paper filter, change it.
Change the oil
Changing the oil when a season (under normal use) keeps the motor healthy and removes the contaminants, sludge and acids that eat away at engine surfaces over time. Drain that old oil out and refill the crankcase with the type of oil and also the amount that's recommended through the equipment manufacturer.
Sharpen the mower blade
The usual understanding says to sharpen blades once a year. A sharp blade will cut the grass cleanly rather than shredding the grass just like a dull blade will. For safety, you should take away the blade, and when the blade has nicks inside it (from the time you may have hit stones or any other hard objects), it will likely be time for you to replace the blade. There are lots of places to have the blade sharpened, and you can also do it by handle with a rotary tool (like a Dremel).
Clean and lubricate
While you have the blade off, you should remove the grass that will get caked around the underside from the mower and also the deck. Remove grass and other debris in the top of the mower, and wax the clean deck to help keep grass from sticking with it. Oil the wheel bearings along with other areas as recommended through the equipment's owners manual.
Adjust the cutting height - longer is better
Ask lawn professionals concerning the most typical mistake made and they'll say it is cutting the grass way too short. Lawns cut to a taller length tend to be healthier and much more weed resistant, in addition to holding water better. So adjust your cutting height to between 3-4 inches. Optimal cutting height actually depends upon the kind of grass you have. For those who have St. Augustine grass like lots of people in Florida do, you'll work between 2-3 inches. It's easy to find accurate information on this if you to research the internet. Just don't cut the grass too short and it will be in better health long-term.
Add ethanol fuel additive before refilling gas tank
Should you left fuel within the tank before putting it away for that winter, hopefully you treated the fuel with an ethanol protectant to ensure the fuel stayed fresh within the winter and didn't separate. Whenever you add fresh fuel, increase the ethanol fuel treatment. Whatever you decide to add should contain water absorbers to handle the water it is going to absorb over the season along with a protecting lubricant to slow the solvency damage that ethanol is wearing lawn equipment. Treating the fuel is an essential key to making your mower last its longest.
Lastly, replace your spark plug and you're good to go for another season.
