I had a hunch the other day about a mower I was looking at, that the service intervals just might have been a bit over-long. So it suddenly occurred to me to ask the owner, "Hey, is your grease gun handy? I would like to squirt a little grease into these spindles." And the guy says, "He!!, man, I'm no mechanic. So I get everything done at the dealer. Every spring. First thing before the customers start calling, _________ [name of local dealer] goes through the whole works." I managed to keep from telling him he was an idiot. And somebody else can buy his mower. It just had about 400 hours on it, but it sure sounded like a lot more.
