The John Deere 770G, 770GP, 772G, 772GP Motor Grader Technical Service Repair Manual TM13027X19 is the complete factory repair reference for all four John Deere G-Series Motor Grader models — 630 pages of detailed factory repair procedures, precise engineering specifications, complete hydraulic system schematics, full electrical wiring diagrams, and comprehensive component overhaul guidance covering every repairable system on the 770G, 770GP, 772G, and 772GP Motor Graders in a single authoritative factory document.

Four G-Series Motor Grader Models — One Complete Factory Repair Reference

TM13027X19 covers all four John Deere G-Series motor grader variants in a single factory document:

John Deere 770G Motor Grader — the standard rear tandem drive variant of the 770-class G-Series motor grader, powered by an electronically controlled John Deere PowerTech engine meeting current emissions standards and delivering reliable power for road maintenance, finish grading, and general earthmoving. All 770G-specific specifications, engine data, hydraulic system data, electronic system data, and repair procedures are documented throughout TM13027X19 with clear 770G model notation.

John Deere 770GP Motor Grader — the plus-drive all-wheel drive variant of the 770-class G-Series motor grader. The 770GP incorporates the G-Series all-wheel drive system — hydraulically driven front axle with individual front wheel hydraulic drive motors providing additional traction at the front wheels in addition to the rear tandem drive — delivering significantly improved traction and blade force for heavy cutting, deep grading, and difficult surface conditions. The G-Series plus-drive all-wheel drive system on the 770GP incorporates updated hydraulic motor and control valve technology compared to the earlier AH-variant AWD system. All 770GP-specific AWD specifications and all AWD-specific repair procedures are documented throughout TM13027X19 with clear 770GP model notation.

John Deere 772G Motor Grader — the standard rear tandem drive variant of the 772-class G-Series motor grader, delivering increased engine power, increased hydraulic system capacity, and increased tandem drive torque compared to the 770G for higher-production road construction, heavy earthmoving, and demanding grading applications. All 772G-specific specifications and repair data are documented throughout TM13027X19 with clear 772G model notation.

John Deere 772GP Motor Grader — the plus-drive all-wheel drive variant of the 772-class G-Series motor grader — combining the increased power and hydraulic capacity of the 772G platform with the G-Series all-wheel drive system for maximum traction and blade force in the most demanding grading and earthmoving conditions. The 772GP is the highest-capability variant in the G-Series motor grader range covered by TM13027X19. All 772GP-specific AWD specifications and repair procedures are documented throughout TM13027X19 with clear 772GP model notation.

All four G-Series models share the same fundamental motor grader architecture — the same circle drive system design, the same moldboard and blade system, the same tandem chain drive layout, the same hydraulic system architecture, the same articulated frame configuration, the same front axle lean and steering system, and the same core G-Series electronic control system platform — with model-specific differences in engine power output, hydraulic system capacity, plus-drive all-wheel drive system presence on the GP variants, and component sizing clearly identified throughout TM13027X19.
