Part of the John Deere Repair Manuals.
When the Hi-Lo unit starts slipping mid shift or the rockshaft drifts under a loaded planter, the John Deere 2440, 2640 technical manual PDF answers with 608 pages of factory publication TM1219, Deere's full repair and test book for both tractors. Wiring diagrams trace the charging, starting, and lighting circuits wire by wire, and hydraulic system tests run the pumps, selective control valve, and remote couplers through pressure diagnosis before you pull anything apart. Engine, power train, steering, and brake repair each get their own teardown sections. Torque the front axle cap screws to 406 N·m (300 ft-lbs) and set fan belt deflection at 19 mm before you chase a charging fault. A split tractor waits while you hunt one spec. Print what you need; these pages can take grease on the bench while the bookmarked, keyword-ready file stays clean.
