I recently found a great new product which solves my frustrating problem of cleaning the grass clippings from under my mower deck. Previously, grass clippings would build-up and harden under my mower deck resulting in "clumpy" cutting of my lawn. Last fall, I found a great device which hooks onto my garden hose, place it under the mower and the results are great. I found it on www.empirewasher.com there's directions on the website as well as the packaging. It only costs $19.50 and what a work saver.
