The John Deere 770A, 770AH, 772A, 772AH Motor Grader Technical Service Repair Manual TM1361 is the complete factory repair reference for all four John Deere A-Series Motor Grader models — 1330 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 770A, 770AH, 772A, and 772AH Motor Graders in a single authoritative factory document.

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

TM1361 covers all four John Deere A-Series motor grader variants in a single factory document — with model-specific repair data, specifications, and procedures clearly identified throughout wherever the four models differ.

John Deere 770A Motor Grader — the standard rear-wheel drive variant of the 770-class A-Series motor grader, powered by a John Deere diesel engine and delivering the blade force, circle drive torque, and tandem drive traction required for road maintenance, finish grading, and general earthmoving applications. All 770A-specific specifications, component data, hydraulic system data, and repair procedures are documented throughout TM1361 with clear 770A model notation.

John Deere 770AH Motor Grader — the all-wheel drive variant of the 770-class A-Series motor grader. The 770AH incorporates the complete all-wheel drive system — hydraulically driven front axle with individual front wheel hydraulic motors providing additional traction at the front wheels in addition to the rear tandem drive — delivering significantly improved traction and pushing force for heavy cutting, deep grading, and difficult terrain conditions where standard rear-wheel drive traction is insufficient. All 770AH-specific specifications including all-wheel drive hydraulic motor specifications, all-wheel drive clutch system specifications, and all AWD-specific repair procedures are documented throughout TM1361 with clear 770AH model notation — including the complete all-wheel drive system repair section that is unique to the AH variants and does not apply to the standard 770A and 772A.

John Deere 772A Motor Grader — the standard rear-wheel drive variant of the 772-class A-Series motor grader, delivering increased engine power, increased hydraulic system capacity, and increased tandem drive torque compared to the 770A for higher-production road construction, heavy earthmoving, and demanding grading applications where the additional power and blade force of the 772-class are required. All 772A-specific specifications, component data, and repair procedures are documented throughout TM1361 with clear 772A model notation.

John Deere 772AH Motor Grader — the all-wheel drive variant of the 772-class A-Series motor grader, combining the increased power and hydraulic capacity of the 772A platform with the all-wheel drive system of the AH variants for maximum traction and blade force in the most demanding grading and earthmoving conditions. The 772AH represents the highest-capability variant in the A-Series motor grader range covered by TM1361. All 772AH-specific specifications, all-wheel drive data, and repair procedures are documented throughout TM1361 with clear 772AH model notation throughout.

All four models share the same fundamental A-Series 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 electrical system platform — with model-specific differences in engine size, hydraulic system capacity, all-wheel drive system presence on the AH variants, component sizing, and torque specifications clearly identified throughout TM1361.

FAQ: 770A, 770AH, 772A, 772AH Motor Grader (TM1361)

Q: What machines does TM1361 cover?
TM1361 covers all four John Deere A-Series motor grader models — the 770A, 770AH, 772A, and 772AH — in complete factory repair detail across every major system. All four models are covered in a single manual with clear model-specific notation throughout wherever engine size, hydraulic capacity, all-wheel drive system presence on the AH variants, or other specifications differ between models.

Q: Why is TM1361 1330 pages?
TM1361 is 1330 pages because it covers four distinct motor grader models — including two all-wheel drive variants with their unique AWD system repair sections — across all major mechanical systems including the complex circle drive system, tandem chain drive system, all-wheel drive system on the AH variants, multiple hydraulic systems, articulated frame steering, front axle and wheel lean system, complete electrical systems for all four models, and comprehensive wiring diagrams for all variants. The four-model coverage with model-specific data throughout accounts for the exceptional page count.

Q: How many pages does TM1361 contain?
TM1361 contains 1330 pages of complete factory repair information covering every repairable system on the John Deere 770A, 770AH, 772A, and 772AH Motor Graders.

Q: Is this the official John Deere factory repair manual?
Yes. TM1361 is the original technical service repair manual written and published directly by John Deere. All repair procedures, torque specifications, hydraulic pressure values, circle drive gear backlash specifications, tandem chain tension specifications, AWD clutch pack clearances, wear limits, and wiring diagrams are factory-accurate John Deere engineering data.

Q: What format is it and when will I receive it?
PDF digital download with instant access immediately after purchase. Compatible with PC, Mac, iOS, and Android. No shipping, no backorders — immediate delivery.

Q: Can I print pages from the PDF?
Yes. Fully printable. Print individual pages, specific sections, or the complete manual. Many technicians print hydraulic schematics, circle drive gear backlash specifications, tandem chain tension tables, AWD clutch pack clearance data, wiring diagrams, and torque specification tables to keep at the bench during repair work.
