John Deere has upgraded their G-Series motor grader line to meet Tier 4 Final emissions standards.
The 12 models in the G-Series—670G/GP, 672G/GP, 770G/GP, 772G/GP, 870G/GP, 872G/GP—all weigh the same as their Tier 4 Interim predecessors.
Diesel particulate filter cleaning occurs automatically, and the DPF can go up to 15,000 hours before ash removal.
Upgrading the 220- to 287-net-horsepower G-Series allowed Deere to include improvements requested by customers. The new series includes better all-around lighting, a more modern radio, an improved rear view camera with a dedicated monitor and upgraded cab features. For 2014, a new laminated cab glass option will be available.
