Part of the John Deere Repair Manuals.
This John Deere Technical Manual (TM1491) covers the GX70, GX75, GX85, SX85, GX95, SRX75, and SRX95 riding mowers. It is the factory service documentation written for experienced technicians, spanning 457 pages across nine sections: Safety, Specifications, Engine, Electrical, Power Train, Steering, Brakes, Attachments, and Miscellaneous.
These mowers run John Deere 'K' Series FC290V and FB460V engines or the Briggs & Stratton 28M707, and the manual keeps all information on each system together. You get theory of operation, component locations, troubleshooting charts, diagnostics, tests and adjustments, and step by step repair procedures.
With torque values, spark plug gaps, fuel capacities, and wiring schematics included, you can diagnose a no-start, chase a charging fault, or rebuild the engine and deck drive on your own bench. Delivered as a downloadable PDF you can search and print.
