John Deere has launched three new G-Series excavators with Tier 4 Interim-certified engines, more power, and cab improvements for increased visibility. The new series includes the 250G, 290G, and 350G, which range from 191 to 299 net horsepower. The new machines retain a number of key features from the previous D-Series, such as the Powerwise III management system. The cooling system cools on demand and has an optional reversing fan to blow out debris. The operator’s station features a full-suspension, high-back seat that adjusts independently from or together with the control console to accommodate any size operator. The next models within the series, the larger 470G, 670G, and 870G, will be formally introduced later this summer.
