I posted this problem on the commercial site as well, but I'm still looking for advice... I have a new scag turf tiger, 27 Kohler...at the dealer everything checked out fine. I ran it for 5 hours, and changed the oil...HOWEVER..., when I went to add the new oil, I discovered that the oil dipstick was GONE...and the only place it could go was down in the oil res........How much damage can this cause, since for all I know, it could have fell off in the 1st 5 minutes and been bouncing around down there...the engine only has 5 total hours on it! What if the dealer somehow finds and removes it and says "it didn't hert anything"...COULD it have caused problems?,,,What kind....?...Anybody???
