Just purchased a new RSX 850i Trail model several weeks ago and have a few questions can someone tell me where the battery is located and how to get to it? The driver’s seat rises up but the passenger seat will not. Is there a different release for the passenger seat? Other than these minor issues it’s a great machine. One more question about the 850i, the owner’s manual recommends John Deere 0 – 40w oil however my dealer said I should use 15 -40w after the first oil change. Is my dealer correct in telling me this?
