Re: Washout Ports
Forget this gimmick. It came on my JD 48" deck and I'd never use it. Its less effective than a garden hose sprayer and only serves to wet down the corrosive clippings for the most part.
Think of it. If you used your garden hose from one side of the deck to spray under the deck, how much would you be able to get out? Yep, not much. AND what it can't get is left as just soaked and stuck corrosive grass clippings. You are better off just to leave the clippings as they are to dry, then periodically, and properly, scrape out the dried stuff.
My routine is to use the back pack blower to get as much off from under and above the deck as possible, park it as is, and let it dry, with a periodic scrape out with a plastic scraper. Once dry, it can be fairly easy to remove most of it. Seasonally I remove the deck and do a power wash, disassemble the bearings, do an inspection, cleaning, drying, and repacking.
Zero issues except the usual scrapes etc....
