The Farmall 706 tractor is a classic row-crop tractor that was manufactured by International Harvester from 1963 to 1967. International Harvester was a company that produced high-quality agricultural machinery and equipment for over a century. The Farmall 706 is a versatile and powerful tractor designed to meet the needs of farmers and other agricultural workers.

The Farmall 706 tractor is available with four different engine options, including two gasoline/LP-gas engines and two diesel engines. The two gasoline/LP-gas engines are six-cylinder engines, while the two diesel engines are also six-cylinder. The engines provide ample power and torque to handle a variety of agricultural tasks. The gasoline/LP-gas engines have a displacement of 4.3 liters, while the diesel engines have a displacement of 5.9 liters.

The Farmall 706 tractor is equipped with one of two transmissions. The first is a sliding gear transmission with 8 forward and 4 reverse gears and dry disc clutch. The second option is the Torque Amplifier transmission with 16 forward and 8 reverse gears. The Torque Amplifier transmission provides a wider range of speeds and gears, making it ideal for more demanding tasks. Both transmissions are reliable and durable, ensuring that the tractor can handle the toughest jobs.

The tractor is equipped with hydrostatic power steering, which makes it easy to maneuver and control, even in tight spaces. It also features hydraulic dry double disc brakes, which provide strong and reliable stopping power. The Farmall 706 is available with either an open operator station or an optional cab. The cab provides protection from the elements and a comfortable working environment for the operator.

The tractor is equipped with a large fuel tank, with a capacity of 124.9 liters (33 US gal.; 27.5 Imp. gal) for gasoline and diesel fuel and 147.6 liters (39 US gal, 32.5 Imp. gal) for LP-gas. This ensures that the tractor can operate for long periods without the need for frequent refueling.

Features Of The Farmall 706 Tractor

The Farmall 706 tractor is a reliable and efficient tractor that offers several benefits to the agricultural sector. Its powerful engines, reliable transmissions, and other features make it ideal for a variety of tasks, from plowing and planting to harvesting and hauling. Let’s learn in-depth about these features.

Engine

The Farmall 706 tractor came with four engine options, each with unique specifications. The IH D282 engine is a six-cylinder natural aspirated diesel engine with a displacement of 4.6 L and a cylinder bore of 94.0 mm. Its piston stroke is 112.0 mm, and it delivers excellent torque and power output for demanding tasks on the farm. This engine is known for its durability and reliability, making it a popular choice for farmers who require a hardworking engine.

The IH D310 engine is another six-cylinder natural aspirated diesel engine option available with the Farmall 706 tractor. With a displacement of 5.1 L and a cylinder bore of 98.0 mm, this engine delivers even more power and torque than the IH D282 engine. Its piston stroke is 111.0 mm, and it is also known for its excellent reliability and durability.

The IH C263 engine is a six-cylinder natural aspirated gasoline/LP-gas engine option for the Farmall 706 tractor. Its cylinder bore is 90.0 mm, and its piston stroke is 112.0 mm. With a displacement of 4.3 L, it is a smaller engine compared to the diesel options. However, it still delivers adequate power for light to medium-duty farm work.

The fourth engine option available with the Farmall 706 tractor is the IH C291 engine, which is also a six-cylinder natural aspirated gasoline/LP-gas engine. Its cylinder bore is 95.0 mm, and its piston stroke is 112.0 mm, with a displacement of 4.8 L. This engine provides even more power than the IH C263 engine and is a good choice for demanding farm work. However, it is not as fuel-efficient as the diesel options.

Transmission

The Farmall 706 tractor comes with two transmission options – sliding gear with dry disc clutch and torque amplifier. The sliding gear transmission features 8 forward and 4 reverse gears, allowing the operator to select the appropriate speed for the job at hand. The maximum speed for the sliding gear transmission is 29.8 km/h (18.5 mph) in forward and 14.5 km/h (9.0 mph) in reverse.

On the other hand, the torque amplifier transmission has 16 forward and 8 reverse gears, which provides the operator with a wider range of speed options. The torque amplifier transmission also allows the operator to shift gears without using the clutch pedal, making the gear-shifting process smoother and more efficient. The maximum speed for the torque amplifier transmission is also 29.8 km/h (18.5 mph) in forward and 14.5 km/h (9.0 mph) in reverse.

Both transmission options offer reliable and efficient performance, and the choice between the two will depend on the specific needs of the operator and the tasks at hand. The sliding gear transmission is ideal for tasks that require a wider range of speed options and smooth shifting, while the torque amplifier transmission is better suited for tasks that require more power and less speed.

Hydraulic System

The hydraulic system of the Farmall 706 tractor features an open-center hydraulic type with a hydraulic capacity of 64.4 L (17 US. gal, 14.2 Imp. gal.). It has the option of having one or two valves and provides a total flow of 24.0 gpm (90.8 lpm). The hydraulic system is responsible for providing power to various attachments such as loaders, backhoes, and other implements. The open-center design allows for a steady flow of oil to be provided to the hydraulic system, ensuring smooth and efficient operation of the attachments. The large hydraulic capacity and high flow rate make the Farmall 706 tractor a versatile machine suitable for a wide range of applications.
