Champion Road Machinery 700 Series Grader Service Repair Manual Download PDF VEHICLE/EQUIPMENT INTRODUCTION: Champion Road Machinery, later absorbed into Case/New Holland and eventually CNH Global, was a well-respected manufacturer of highway graders and road construction equipment. The Champion 700 Series motor grader range was designed for highway construction, road maintenance, snow removal, grading, and fine surface finishing tasks that required the precision and power that only a dedicated motor grader can deliver. These machines were the backbone of state highway departments, county road crews, and commercial road construction contractors across North America. A motor grader differs fundamentally from other earthmoving equipment in that its primary working tool — the moldboard blade — is positioned between the front and rear axles and can be angled, tilted, and shifted laterally to achieve precise grade profiles. The Champion 700 Series featured a circle drive mechanism that allowed 360-degree blade rotation, side-shift capability for crown maintenance, and sophisticated blade control systems that enabled operators to perform everything from rough cut-and-fill grading to fine finish passes at tight tolerances. The 700 Series grader was designed around a heavy-duty articulated frame with a robust diesel engine, powershift transmission, and rear tandem drive axles with walking beam suspension for ground conformity over uneven surfaces. The cab placement on Champion graders provided excellent forward visibility to the moldboard and front scarifier, and the machine control system allowed both manual lever operation and (in later configurations) integration with laser or GPS grade control systems for automated fine grading. The modular component layout simplified component removal and replacement, making these graders serviceable even in remote field conditions.
