Hi, I'm Daniel Penselin, and I'm showing you how to clean the deck of a riding lawn mower. Things you'll need: A lawn mower, and a hose. Step one: You'll need to ride your mower to an area where you can clean it. Step two: Pull the hose over to your mower so you'll be able to use it there. And then, by hand, remove all the grass from the deck of your riding lawn mower, so the belts will be clear of any debris. Step four: Return your lawn mower to a sheltered area. And that is how you clean the deck of a riding lawn mower.
