The one thing the consumer has to worry about is corrosion. The first thing we removed was that stupid washout hose adapter provided for you for their interests, not yours. You honestly going to hook a garden hose spraying nasty water supplied by the city to a device formed out of cheap metal, partially painted- what do you think happens. Rust exacerbates. Bearing seals are designed to help keep the lubrication in, not necessarily to keep dirt and water out. Grease is a giant factor involving the length of time a bearing has before it starts making noise on it's way out. Factory is going to use the cheapest grease they can find to make sure the bearings fail in a certain amount of time, so they can make money selling you new ones, or better yet, having them do the job for you. Keeps them in business and your wallet empty. They don't care. From what I have been reading from others, is that the deck didn't make through it's first season of operation. Why? Probably because of all of the above.
