Before you break out your lawnmower and rev it up, take the time to give it a quick once over so it’s in tip-top condition for the mowing season ahead. Before you do any maintenance, remove the lead from the spark plug to prevent accidental starting.
Sharp blades make for a cleaner cut on your grass, which helps it stay healthy and make the job easier. Carefully turn your lawnmower over and check the blades. Dented, bent or blunt blades should be removed. If you have a bench grinder or metal file you can resharpen and replace them. If not, a new set of blades will cost around $20
Change the Oil
Check your lawnmower’s manual to find out how to drain the oil. Pour it into a container and check with your local waste disposal authority about recycling. After it’s fully drained, replace all the oil caps and plugs and fill it with new oil. Use the right type of oil and amount to suit your particular mower. Turn it back over and fill up with some fresh oil. Whilst you’re at it, it’s not a bad idea to replace your oil filter at the same time.
Air to breathe
A clogged air filter won’t let enough air into your engine for it to run smoothly. Remove the air cleaner and inspect it. Paper filters should be replaced whilst foam filters can be cleaned. Wash the filter with hot water and detergent, let it dry then put it back in. If the filter is in poor condition even after a wash, replace it.
Keep things moving
Spray moving parts like the throttle mechanism, the wheel axles and the height adjuster with a lubricating spray like WD-40.
To ensure consistent starting and trouble free operation, change your spark plug every spring. Before removing it, clean around the plug to prevent any debris from getting into the engine when it comes out. Unscrew the plug using a spark plug socket, pull it out and replace it with the new one. Take care not to over tighten the new plug.
