Part of the John Deere Repair Manuals.
This 429-page John Deere GT242, GT262, GT275 Technical Manual (OEM #TM1582) puts the complete factory service data for these Lawn and Garden Tractors in your hands. Inside: wiring harness diagrams and pinouts for the Electrical section, hydrostatic power train schematics, and a full troubleshooting section covering engine, gear power train, brakes, and mower deck attachments (38, 44, and 48-inch decks included). You get theory of operation, tests and adjustments, and repair procedures for every system, plus torque tables for both standard and metric fasteners. Torque the blade cap screw to 68 N-m (50 lb-ft) and the spark plug to 20 N-m (177 lb-in) exactly like Deere specifies, not a forum estimate. Your mower deck problems, brake linkage issues, and electrical faults all trace back to a spec in here. Bookmarked by section and searchable by keyword, so you can jump straight to the fix from your phone or tablet in the shop.
