Part of the John Deere Repair Manuals.
This 36-page John Deere 70 Service Manual also covers the 60, giving you one PDF for both Lawn Tractor models instead of hunting down two separate books. Open it up and you get full wiring diagrams for tracing charge circuit faults, a troubleshooting section for hard starting, backfiring, and loss of power, plus torque specs and step-by-step procedures for engine removal, transaxle service, and PTO clutch adjustment. You also get the steering gear, carburetor, and belt replacement procedures laid out in the same detail. Torque the cylinder head bolts to 140-200 in. lbs. and top off the crankcase at 1-1/2 U.S. pints of AM 30730 summer oil before you fire it up. No more guessing why the charging circuit won't hold a charge. Bookmarked and searchable; jump straight to the section you need and get back to the shop.
