I saw a little yellow plastic adapter somewhere last year that screws on the end of a waterhose. It is flat on the end and it hooks under the edge of your deck. Theory is, engage the blades, turn on the water, and the blades sling the water around hard enough to clean the underside and the blades. I have done this with just the hose and it really works. Especially if it is done before too much builds up. Just wondering if anyone else has seen this and knows where I can get one.
