The John Deere 310K is a two-wheel drive or four-wheel drive backhoe loader. This model was manufactured between 2012 and 2019. The John Deere 310K is equipped with a 276 cubic inches (4.5 L) PowerTech Plus 4045HT073 four-cylinder turbocharged diesel engine with a rated power of 88 hp (65.6 kW). The powershift transmission includes a hydraulic wet clutch, 4x2 full power shift gearbox, and single stage torque converter.

The maximum forward speed - 20.6 mph (33.1 kph), a max reverse speed - 8 mph (12.9 kph). The open center hydraulic system used a single gear pump with a rated fluid flow of 28 gal/min (106 l/min). The hydraulic pressure is 220 bar (3200 psi) for loader, and 250 bar (3625 psi) for backhoe. The John Deere 310K is equipped with 11Lx16 front tires and 19.5Lx24 rear tires. The wheelbase is 83" (2100 mm) for 2WD models, or 84" (2130 mm) for 4WD models.

The loader’s max lift height is 133.6" (3380 mm) at pin and clearance with bucket dumped is 106" (2690 mm). The lift capacity is 6600 lbs (2993 kg) at maximum height (bucket pin), and breakout force is 9350 lbs (4240 kg). The loader is compatible with a 86" bucket.

The standard backhoe has a maximum digging depth of 171" (4340 mm), 2-ft flat digging depth of 170.8" (4320 mm), and overall reach from swing pivot of 215" (5440 mm) at ground line. The bucket dig force is 11105 lbs (5035 kg), and dipperstick dig force is 7005 lbs (3177 kg). The backhoe is equipped with 12", 18", 24", and 30" buckets.
