Part of the John Deere Repair Manuals.
Deere's print shop, not a forum, produced this one: the John Deere 111 technical manual PDF, factory publication TM1206, all 654 pages covering five lawn tractors in the 100 series, from the 108 up through the 116. Wiring diagrams trace the cranking, ignition, and charging circuits separately for each model, so the schematic you follow matches the harness under your hood. Carburetor and governor linkage adjustments, transaxle and hydrostatic drive teardowns, and PTO clutch service fill the rest of the book, with the three engine sections taking up roughly a third of it. Set PTO clutch cone clearance at 1.5 mm (1/16 in.) and torque spark plugs to 20 to 27 N·m (15 to 20 ft-lbs). A torque figure somebody remembered wrong strips aluminum threads for good. Bookmarked and searchable by keyword, the download has your tractor cutting grass again before the weekend is out.
