The 12 models (670G/GP, 672G/GP, 770G/GP, 772G/GP, 870G/GP, 872G/GP) in John Deere’s G Series motor grader line, with net horsepower ranging from 220 to 287, now have John Deere PowerTech Tier 4-Final engines. Six of the units (those models ending in two: i.e. 872G) feature six-wheel drive, for added traction and a 30 percent increase in blade pull. All models weigh the same as their Tier 4-Interim predecessors. New LED worklights provide better illumination around the G-Series models. Operators also have the ability to utilize satellite radio with Bluetooth capability. A new laminated cab glass option will be available in 2014.
