The Greenworks 20-inch 12 Amp Corded Lawn Mower has a lot of features that can make your mowing experience enjoyable. Since it is corded you dont need to stop to recharge a battery or gas up. It is a three-in-one that has mulching side discharge and rear bagging capabilities. There are seven cutting height positions ranging from 1.5 to 3.75 inches and you can adjust the height with a single lever. Plus the 10-inch rear wheels 7-inch front wheels and 56-pound size make it easy to push around the yard.
Other items and supplies include a plastic drip tray motor oil and a container for waste oil. Often a large piece of cardboard is useful as well an old rag or cloth. Also know that this guide deals with push or self-propelled mowers not riding mowers. While some advice here applies they are another animal altogether.
I know that many people prefer to hose their mowers down with a garden hose. I admit I have done it. Still doing that is risky. If water gets into the wiring air filter or engine you could really do some damage. Hand washing with damp rag is a drag but also your safest bet.
