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.
Other buyers comment that the mower feels and look like a toy. It seems flimsy. But they also found it could handle child-swallowing yard growth. One of the coolest features of the Toro Recycler 22-inch Personal Pace Variable Speed Gas Walk Behind Self Propelled Lawn Mower that kept coming up in our research is the blade-brake clutch. This allows you to stop the blade without stopping the motor of the mower which is helpful for moving debris out of the way.
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.
