John Deere 310SK Backhoe Loader

The John Deere 310SK is a 2-wheel drive or 4-wheel drive backhoe loader. This model was manufactured between 2013 and 2019. The JD 310SK driveline components: a John Deere PowerTech Plus 4045HT073 four-cylinder turbocharged diesel engine, and 5x3 power shift transmission with a single-stage torque converter. A 276 cu.in (4.5 L) engine has a cylinder bore of 4.19" (106 mm), piston stroke of 5" (127 mm), and rated power of 96 hp (72 kW).

The max travel speed (forward and reverse): 25 mph (40 km/h) / 12.8 mph (20.6 km/h). The open center hydraulic system includes a tandem gear pump with fluid flow rate of 28 gpm (106 lpm) using a loader, and 36 gpm (136 lpm) using a backhoe. The main relief pressure is 250 bar (3625 psi). The four-wheel drive models are equipped with 11L-16 front tyres and 19.5L-24 rear tyres. The 340/80R18 front tyres and 500/70R24 rear tyres are used for two-wheel drive models.

The front end loader has a lift capacity (at pin) of 7350 lbs (3340 kg) to full height of 134.4 inches (3400 mm), and boom breakout force of 11050 lbs (5020 kg). The bucket dump clearance is 106 inches (2690 mm) meters at max dump angle of 45 degrees. The loader is fitted with 86 inches (2175 mm) and 92 inches (2330 mm) buckets.

The backhoe with standard stick digs to a max depth of 174.7 inches (4420 mm). The digging force is 8090 lbs (3680 kg) using the standard dipper cylinder and 11990 lbs (5450 kg) using the bucket cylinder. The reach from swing pivot at ground line is 219.7 inches (5560 mm). The backhoe can be fitted with 12" (305 mm), 18" (455 mm), 24" (605 mm), and 30" (760 mm) buckets.
