John Deere 670B to JD770 specifications

670B and 672B: distinguish the grader's front drive from its steering

The original 670B sheet describes a direct-drive planetary PowerShift transmission, an inching pedal and a tow disconnect. Its working-speed schedule and the separate disconnect matter when preparing a transport or recovery enquiry. A transmission described as PowerShift does not mean it can be towed with the driveline left connected.

Deere distinguishes the operator-controlled differential lock from frame articulation and front-wheel lean. Unlocking the differential assists maneuvering, while articulation can put the tandems on firmer ground and reduce side drift. These controls address different parts of the machine's behavior; they are not interchangeable descriptions of steering.

Original Deere670B brochure: transmission, final drive, articulation and differential lock

The 672B adds a hydraulic front-wheel-drive system with a reversible motor at each front wheel. Its manufacturer sheet gives normal and aggressive operating modes and says the drive freewheels at transport speeds or when unused. The standard and optional high-speed systems cover different gear ranges.

Confirm the fitted front-drive package before diagnosing loss of front-wheel assistance at a particular speed.

Its rear tandem drive remains a separate planetary-and-chain arrangement. The oil-bath chain description does not identify the source of a front-drive hydraulic problem. Likewise, the wet service brakes and mechanically operated parking brake are separate systems, even though both act on the tandem wheels.

Original Deere672B brochure: standard/optional hydraulic front drive, tandem chains and independent braking systems

C Series II power ratings depend on the selected gear

The C Series II sheet separates the 670C's all-gear rating from the 670CH's gear-dependent power schedule. Comparing only the largest horsepower entry would hide the lower ratings used in other gears. Keep the power band with its gear range when deciding whether a quoted figure describes the grading work you intend.

That sheet also identifies tyre-dependent front-axle clearances. The earlier comparison's 24-foot entries for the 670C and 670CH are unit errors: the manufacturer lists inches for the specified tyre configuration. Other tyre options change clearance, so the corrected figure stays qualified rather than becoming a universal transport dimension.

The older B graders and the later C machines remain separate records below. The C Series II publication does not establish equipment fitted to every earlier grader carrying a similar number.
