This 4-page Bolens 18322 parts catalog PDF (OEM #P-553542) breaks down the complete 33 inch tiller attachment, covering both gear drive and hydrostatic models plus the optional 18320 extension. You get the full tiller assembly diagram, a gear case assembly view with its own parts list, factory part numbers for every tine, shaft, and bearing, and a common hardware reference for the fasteners nobody ever labels. Serial number ranges up front confirm you're ordering for the right build. When you refill the gear case, it takes 20 oz. of gear lubricant; the factory tubes hold 8 oz. each, so grab three. NOS parts and swap-meet finds don't come tagged, and guessing gets expensive. Bookmarked with a real text layer; open it on any screen in the garage, match your part number, and get the tiller turning dirt again this season.
