Built for the 670C, 670CH, 672CH, 770C, 770CH, and 772CH Motor Graders

The John Deere 670C, 670CH, 672CH, 770C, 770CH, and 772CH are C-Series motor graders representing John Deere's advancement of the proven B-Series motor grader platform with C-Series PowerTech engine technology, updated electronic machine control systems, refined hydraulic performance, and improved operator environment — all built for productive road construction, road maintenance, gravel road grading, drainage, precision grade control, and earthmoving applications.

The 670C is the mid-size C-Series motor grader without HFWD. The 670CH is the mid-size model with Hydraulic Front Wheel Drive — the H suffix identifying HFWD equipment. The 672CH is a configuration variant of the mid-size C-Series range with HFWD. The 770C is the larger C-Series motor grader without HFWD offering increased engine power and blade capacity for more demanding applications. The 770CH is the larger model with HFWD for superior traction on loose or wet road surfaces. The 772CH is the configuration variant of the larger C-Series range with HFWD providing maximum blade size and maximum production capability. TM1607 covers all six C-Series models completely — with all model-specific and HFWD-specific differences clearly identified throughout the 888 pages.
