Place a drip pan or other container on the side of the mower with the filler. Carefully tilt the mower so oil drains out and into the pan. Discard the spent oil into a proper disposal vessel. Now slowly pour fresh oil into the mower. For the specific type of oil you need check your instruction manual. Make sure to add only as much as your particular model requires. Remember to let the mower sit undisturbed for a few minutes so the oil settles properly inside the engine.
The 190 cc engine allows you to mow at a decent clip and it starts more easily and runs more efficiently than most side-valve engines. Also the rear-wheel drive makes it so you can mow inclines and hills effortlessly. There are more features than we have space to cover here but we would be remiss if we didnt touch on the Versamow system. This system allows you to choose how much grass is mulched and how much is bagged depending on your yards conditions. It also lets you shred leaves so you no longer need to use your leaf blower.
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.
