Ford 7710 Tractor Troubleshooting

The Ford 7710 is a 10-series row-crop tractor. This model was manufactured between 1982 and 1990. The Ford 7710 is powered by 268 cubic inches (4.4 L) Ford 4-cycle four-cylinder liquid-cooled diesel engine with a maximum output power of 97 hp (72.3 kW) and 377 Nm (278 lb-ft) of peak torque at 1400 rpm.

The Ford 7710 tractor is equipped with three types of transmission. Type 1: 8x2 Dual-Range transmission. Type 2: 16x4 Dual-Power partial power shift transmission. Type 3: 16x8 synchromesh partial powershift transmission. Max. travel speed (forward and reverse): 19 mph (30.6 km/h) / 9 mph (14.5 km/h).

The open center hydraulic system used a gear pump with fluid flow rate of 18.2 gal/min (68.9 l/min). The hydraulic pressure is 172.5 bar (2500 psi). The 2WD models are equipped with 7.5x16 front tires and 15.5x38 rear tires. The 11.2x24 front tires and 18.4-30 rear tires are used for 4WD tractors. The wheel base is 101.6" (2580 mm) for 2-wheel drive models and 97.6" (2470 mm) for 4-wheel drive models.

The Ford 7710 is compatible with a Ford 777B loader with lift capacity to full height of 2500 lbs (1134 kg), Ford 777D loader with lift capacity to max height of 2900 lbs (1315 kg), or Ford 7412 loader with lift capacity to full height of 3000 lbs (1360 kg).
