John Deere 310C Backhoe Loader

The John Deere 310C backhoe loader was manufactured between 1986 and 1991. The JD 310C driveline system components: a John Deere 4.239D four-stroke 4-cylinder naturally aspirated diesel engine, and 4x4 manual shift transmission with single stage dual phase torque converter.

A 239 cubic inches engine output power is 69 Hp (51.5 kW), and a max. torque is 252 Nm (186 lb-ft) at 1200 rev/min. The maximum travel speed (forward and reverse): 22.4 mph (36 km/h) / 20.2 mph (32.5 km/h). The open center hydraulic system used a gear pump with rated fluid flow of 35 gpm (132 lpm).

The hydraulic system pressure is 2700 psi (190 bar). The John Deere 310C backhoe loader is fitted with 7.50-16 (2WD) or 11L-15 (4WD) front tires, and 16.9-24 (2WD) or 19.5L-24 (4WD) rear tires.

The loader’s max lift height is 130 in (3300 mm) at pin, and bucket dump clearance is 106 in (2690 mm). The lift capacity is 5600 lb (2540 kg) at maximum height (pivot pin), and breakout force (bucket on ground) is 8700 lb (3945 kg). The time to raise the boom is 3.3 seconds from ground line to max height, and bucket dump time is 1.1 seconds. The loader is equipped with a 92 in (2330 mm) standard materials bucket.

The backhoe has a maximum depth of 171 in (standard stick) or 218 in (extendable stick). The dipper stick digging force is 11570 lb (standard stick) or 11400 lb (extendable stick), and bucket digging force is 6650 lb (standard stick) or 4540 lb (extendable stick). The reach from swing pivot at ground line is 253 in (extendable stick). The backhoe can be fitted with 12", 16", 18", 24", 30", 36" buckets.
