Next you will change the oil. To lower oil viscosity and get it moving freely run the engine for a few minutes. Now shut the engine off and roll the mower onto a piece of cardboard or drop cloth. Close the fuel line (if your mower has one) and unhook the spark plug as before. Find the oil filler tube and remove its cap. Often the cap also functions as a dipstick.
Lawn mowers are tough. Like any machine though they need regular maintenance to run their best. Worse neglect can cause a mower to fail completely. So before the summer mowing season really kicks into high gear prep your mower right. From cleaning it to changing the oil to sharpening and balancing its blades this guide lays out steps to get your mower and your garden in tip-top shape.
Gather what you need First gather your tools and equipment. You will need a power drill eye protection work gloves and a blade sharpening kit. The kit should come with a ceramic blade sharpener and balancer. Expect to pay about $8 for the kit at your local hardware store. You will also need a torque wrench (or a socket wrench in a pinch) and a wooden block. Consider having a rubber mallet on hand too.
