Part of the John Deere Repair Manuals.
This 746-page John Deere 4010, 4020, 4000 Series Tractors Service Manual puts the complete factory teardown for these Syncro-Range and Power Shift tractors in your hands. Inside you'll find full wiring diagrams for the charging circuit and starter system, hydraulic schematics covering the pump, power steering, and rockshaft circuits, plus a dedicated troubleshooting section for when the tractor just won't cooperate. Your battery spec reads 12-volt, 78-plate, 75-ampere-hour, and the oil-bath air cleaner takes 4-3/4 U.S. pints on diesel models versus 2-3/4 pints on gasoline and LP-Gas versions, straight from the factory page, not a forum guess. No more flipping through a warped shop copy trying to find the differential preload numbers. Every section from Basic Engine to Special Service Tools is bookmarked and keyword-searchable, so you can jump straight to Power Brakes or Final Drive without hunting through 746 pages by hand.
