International Farmall 756 Tractor Operator's Manual
International Harvester 756 Tractor Operator's Manual This operator's manual is the factory operation and maintenance reference for the International Harvester 756 tractor, covering the International 756, the Farmall 756, and their gasoline, LP Gas, and diesel engine versions, running roughly 148 pages of operating procedures, adjustments, lubrication, and troubleshooting. It's the book that came with the machine: break-in and daily start-up procedures, engine and fuel-system operation for all three fuel types, hydraulic and hitch operation, and a full lubrication and specifications reference. Originally published by International Harvester under form number 1 082 649 R2, and delivered here as an instant PDF download you can read on any device or print for the cab. Models covered: International 756 · International 756 All-Wheel Drive · Farmall 756 · Farmall 756 Hi-Clear · Farmall 756 All-Wheel Drive · gasoline, LP Gas, and diesel engine versions About the International Harvester 756 The 756 was built in both International and Farmall forms, and this manual documents them side by side, including the Farmall 756 Hi-Clear and the All-Wheel Drive versions of both the Farmall and the International. What sets it apart from most single-engine operator's manuals is its three-fuel coverage. The same book carries separate operating sections for the gasoline engine, the LP Gas engine with its liquid and vapor tank valving, and the diesel engine with its water-drain, ether-injection starting, and fuel-strainer procedures. All three engines are six-cylinder and governed to 2,300 rpm. The gasoline and LP Gas engines displace 291 cu. in.; the diesel is a 310 cu. in. unit with Robert Bosch injection pump and nozzles. Fuel capacity is 33 gallons for gasoline and diesel, or 39 gallons for LP Gas measured at the 80 percent outage level. All three configurations run a 12-inch single-plate dry-disc clutch and hydraulic disc brakes that can be operated individually or interlocked. Power reaches the ground through a range-and-speed transmission giving eight forward and four reverse speeds, four in High range and four in Low, with an optional Torque Amplifier and a tilt steering wheel and adjustable (including hydraulic) seat for the operator. These tractors remain in active use, and much of what keeps them running correctly, from governed speeds and break-in loads to hitch settings and lubrication intervals, lives in this book. On tractors equipped with the Torque Amplifier the manual notes they cannot be started by towing, and that the engine must be running to provide transmission lubrication when towed. That is the kind of detail only factory documentation carries. What This Manual Covers Instruments & controls: Location and use of the gauges, tellites, levers, and switches, including the LP Gas tank service valves and gauges. Before operating & driving: Break-in procedure, seat and tilt-steering-wheel adjustment, transmission range and speed operation, All-Wheel Drive engagement, towing, and stopping the tractor. Gasoline engine and fuel system: Starting, choke, and fuel-tank operation for the gasoline engine. LP Gas engine and fuel system: Tank valving, carburetor and regulator adjustment, and safety-relief and vapor-return handling. Diesel engine and fuel system: Fuel specification requirements, water and sediment draining, ether starting, and stopping procedures. Torque Amplifier: Operation of the speed-ratio control on so-equipped tractors. Hydraulic system with power steering: Basic system operation plus hydraulic controls for the three-point or two-point Fast-Hitch. Hitches & equipment: Three-point hitch, Two-Point Fast-Hitch, Quick-Coupler, auxiliary valves and remote cylinders, and hitching trailing equipment. PTO & belt pulley: Independent power take-off operation and belt-pulley starting and stopping. Cooling & air cleaning: Coolant service, water pump and alternator-generator belt, and the air cleaner with automatic dust unloader and service indicator. Electrical system: Spark plugs and cables, oil-pressure tellites, storage battery, and cable harness service. Minor engine service & wheels: Governor adjustments, engine speed control lever settings, front and rear wheel tread adjustment, wedge and dual wheels, and front and rear weights. Brakes, clutch & storage: Brake and overcenter hand-lever engine-clutch adjustment, tractor storage, and cold weather precautions. Troubleshooting, lubrication & specifications: Troubleshooting charts organised by possible cause, the Lubrication Guide and Table, Preventive Maintenance Guide, and the specifications section including engine speeds and ground speeds. Why This Manual Matters Three engines, one book. Separate operating and fuel-system sections for the gasoline, LP Gas, and diesel 756 mean you get the exact procedures for your engine, not a generic overview. Multi-model coverage. International 756, Farmall 756, Hi-Clear, and All-Wheel Drive configurations are documented together, including the AWD engage and disengage procedure and the towing notes. The PTO speed detail most owners get wrong. At the rated 2,300 rpm the 540 shaft actually turns 590 rpm. Standard shaft speeds of 539 and 1,014 rpm arrive at 2,100 rpm engine speed, which is why the manual publishes two sets of ground speeds. If you are running 540 equipment, that distinction matters. Hitch and hydraulic operation in detail. Three-point hitch, Two-Point Fast-Hitch, Quick-Coupler, auxiliary valves, and remote cylinders are all walked through for setting up and running implements correctly. Hi-Clear owners, note this. The manual states plainly that Farmall Hi-Clear tractors have standard PTO shafts but do not conform fully to ASAE standards because of their high-clearance construction. The drawbar-to-shaft dimensions are dramatically different from the other two tractors, which affects implement fit. The reference data the job depends on. Break-in loads, governed engine speeds, ground-speed tables, tire pressures, and the Lubrication Guide let you service and set up the tractor to spec. Troubleshooting by cause. The troubleshooting section is organised by possible cause, helping you trace a fault rather than swap parts blindly. Scarce factory literature, restored. Original operator's literature for the 756 is increasingly hard to find. This searchable, restored PDF puts it back in your hands. Full Specifications Looking for the technical numbers before you buy? The International and Farmall 756 specifications page reproduces the manual's specification section in full and free: engine specifications for all three fuel types, PTO and belt pulley speeds, capacities, electrical system with every lamp and bulb part number, tires and tread settings for all three tractors, general dimensions, drawbar and PTO dimensions, shipping weights, and the complete ground speed tables including the Torque Amplifier ranges.
