The 300G LC excavator replaces the 290G LC with 19 percent more horsepower and 17 percent more swing torque and larger hydraulic pumps. It’s powered by a 223-horsepower, certified Tier 4-Final John Deere PowerTech PVS 6.8L engine with a DPF that cleans automatically. The engine uses SCR technology with DEF. The hood is larger for improved access, and the nine-pin diagnostic connector in now in the cab to reduce diagnostic testing time for technicians.
