This John Deere 4555, 4755, 4955, 4560, 4760 and 4960 Operation and Test Manual covers every major system on the tractor and provides the diagnostic logic needed to isolate faults quickly. It is not a repair manual — it is the diagnostic companion that tells you how to test, what readings to expect and how the system is supposed to behave. For complete service information, John Deere also references the repair manual TM1460 and component manuals CTM6, CTM7, CTM11 and CTM17. Those are not included here; this listing is for TM1461 only.

Engine Coverage

The 4555, 4755 and 4955 tractors use the 7.6 liter, 6-cylinder John Deere 6076 engine. The 4555 is turbocharged. The 4755 and 4955 are turbocharged and liquid-to-air aftercooled. The 4560, 4760 and 4960 models are also covered for operation and test purposes. The manual includes engine test specifications, dynamometer test procedures, break-in instructions, fast and slow idle adjustment, valve clearance data, compression pressure, oil pressure and cooling system test procedures.

IMAGES PREVIEW

For 4755 and 4955 tractors equipped with a Robert Bosch electronic governor and power shift transmission, the manual references CTM-11 for diagnostic and repair procedures. ECU diagnostic codes for the 4955 PST tractor are listed in the engine section, including hand throttle sensor codes, actuator solenoid circuit faults, rack position errors and fuel temperature sensor faults.

Transmission Coverage

The QUAD-RANGE transmission section covers operational checks, diagnosis and theory of operation for the 16-speed forward, 6-speed reverse transmission. It includes clutch pressure checks, lubrication pressure checks, circuit leakage isolation, PTO clutch and brake pressure checks and the QUAD-RANGE transmission cycle check. The Power Shift Transmission section covers the 15-speed forward, 4-speed reverse PST with full diagnostic charts, element leak checks, accumulator charging procedures, modulator valve checks and theory of operation for the input planetary, output planetary, direction planetary and all hydraulic control valves.

PTO, axle and differential coverage includes operational checks for the differential lock, diagnosis of differential malfunctions, differential lock pressure testing and theory of operation for the final drive planetary, differential lock and PTO clutch and brake systems for both QUAD-RANGE and Power Shift tractors.

Hydraulic System Coverage

The hydraulic system section is one of the most detailed in the manual, covering the QUAD-RANGE and Power Shift transmission hydraulic systems separately. It includes step-by-step diagnostic charts, high pressure to sump leak checks, high pressure to return leak checks, SCV leak checks, brake and differential lock leak checks, lube reduction valve checks, element leakage checks, clutch system pressure checks, cooler inlet pressure checks, lube pressure checks, transmission pump flow checks, charge flow checks, standby pressure checks, pressure control valve checks, main pump quick checks and main pump flow checks.

The hitch system is covered in its own operational checkout and diagnostic procedure, including EH hitch version identification, hitch calibration, load/draft sensor calibration, fault code analysis and hydraulic tests for the rockshaft valve housing, rockshaft cylinder pressure passages and return passages.

Electrical System Coverage

The electrical section covers the starting circuit, charging circuit, INTELLITRAK monitoring system, lighting circuits and accessory circuits. It includes operational checks, diagnosis procedures, wiring diagrams, connector pin identifications, ground point locations, load center fuse and relay identification, and the INTELLITRAK tachometer modes for accessing diagnostic codes, calibration and sensor data. The charging circuit diagnosis covers the Nippendenso 120-amp alternator, voltage regulator, battery testing and system leakage checks.

It includes preliminary checks, blower motor and compressor clutch checks, engine-on operational checks, refrigerant recovery and recycling procedures, system pressure checks, temperature control switch checks, clutch cycle checks, refrigerant loss switch checks, high pressure switch checks and seat suspension malfunction diagnosis.

Dealer Fabricated Tools

The final section provides instructions for fabricating tools that are identified by the factory as necessary for proper servicing but can be made at the dealership. These include the main pump destroking lead, test leads for automotive-style fuses, special diagnostic jumper lead assortment, air restrictor, MFWD clutch test tool, SCV air pressure test adapter, filter housing assembly, rockshaft leakage test fitting, electronic circuit load tester, tach simulator harnesses, extension and tap-out harnesses, and the CAL/DIAG switch harness.

What This Manual Enables You To Do

With the John Deere 4555 4755 4955 4560 4760 4960 Tractors Operation and Test Manual TM1461 in hand, you can perform the complete machine operational checkout, diagnose faults across every major system, test hydraulic pressures and flows, verify electrical circuit integrity, isolate transmission element leakage, check hitch calibration and response, and confirm that repairs have restored correct operation. The manual gives you the exact test specifications, pressure readings, flow rates, resistance values and voltage ranges that John Deere expects to see on a properly functioning machine.

Because this is the Operation and Test manual rather than the repair manual, it tells you how to find the problem and verify the fix, not how to disassemble and rebuild components. That makes it the ideal companion to TM1460 and the CTM component manuals for anyone who needs to diagnose these tractors accurately before committing to a repair.

Why This Manual Matters

These tractors are complex machines with multiple hydraulic circuits, electronic monitoring systems and transmission options. Guessing at pressures, flow rates or electrical values wastes time and can lead to misdiagnosis or further damage. The John Deere 4555 4755 4955 4560 4760 4960 Operation and Test Manual TM1461 gives you the correct procedures and specifications so that every test is performed the way John Deere intended and every result can be compared against a known standard.

Whether you are a dealer technician, an independent mechanic or an owner who does their own diagnostics, having the factory operation and test information for these tractors means you can approach any fault with a logical, systematic plan rather than trial and error.
