This Kubota M8560 M9960 Workshop Manual (OEM #9Y111-06860) takes these tractors apart at the system level, from Common Rail fuel injection to the four-wheel-drive transmission. Hydraulic schematics trace the full circuit through position control, draft control, and the oil cooler relief valve, while the wiring coverage maps the tractor ECU, engine ECU, instrument panel, and starting system. More than 150 procedures run through the engine, rear axle, brakes, steering, and cabin air conditioning, backed by troubleshooting charts, exploded views, and maintenance schedules down to 50-hour intervals. Injector clamp nuts torque to 24 to 27 N·m; rear wheel mounting nuts to 344 to 392 N·m. Every idle hour costs you money, so the bookmarked, keyword-searchable layout puts the factory answer one search away.

Kubota M8560, M9960 Common Problems This Manual Covers
Kubota M8560 engine cranks but won't start or turns over slowly in cold weather
Inspect battery charge and terminals first; a weak cell shows itself fast in the cold. Confirm engine oil sits at the correct level (full system capacity is 10.7 L with filter, page 49). From there, work the no-start chart, checking air heater relay function and the fuel system for air ingestion before condemning the injection pump.
Manual Section: 1 EngineHydraulic implement won't raise or drops slowly under load with no error codes p. 517
Confirm hydraulic fluid level and condition before anything else. Follow the implement-not-raising sequence; the hydraulic system section starts on page 499. Gauge pump delivery against the allowable limit of 19.6 L/min for ROPS models or 21.1 L/min for CABIN models (page 517). A reading below limit points to worn pump internals or a bypassing relief valve rather than a position-control fault.
Manual Section: 7 Hydraulic SystemBrake pedal feels spongy or tractor pulls hard to one side when stopping p. 427
Measure brake pedal free travel first; spec is 7 to 14 mm (page 427). If travel is in spec but the pedal still feels soft, bleed the master cylinder and both wheel cylinders fully. A hard pull to one side usually means a pad is oil-contaminated. Page 418 holds the full spongy-pedal and uneven-braking sequence.
Manual Section: 4 BrakesTransmission grinds going into gear or pops out of mesh under field load p. 49
Verify transmission fluid level; total case capacity is 60.0 L (page 49). Shift through every range cold and hot to tell whether the fault is temperature-dependent. If gears pop out under load, inspect shift fork wear and detent spring tension; page 247 covers transmission assembly and lubrication before you assume synchro damage.
Manual Section: 2 TransmissionAlternator warning lamp stays lit after startup, battery draining between sessions p. 590
Test alternator belt tension and condition first, then trace the charging circuit with the wiring diagram on page 714. Check battery condition every 100 hours per the maintenance schedule (page 54). If the alternator spins freely but output stays low, confirm the pulley nut is torqued to 58.3 to 78.9 N·m (page 590) before condemning the stator or regulator.
Manual Section: 8 Electrical SystemFrequently Asked Questions
What are the recommended service intervals?
Intervals vary by component. The engine start system, wheel bolt torque, and tie-rod dust cover get checked every 50 hours. Replace the hydraulic oil filter every 300 hours, and change the engine oil and its filter every 400 hours.
What fluids and capacities does this machine require?
Fluids and capacities are model-specific. The ROPS fuel tank holds 90.0 L (23.8 U.S.gals); the CABIN model takes 110 L (29.1 U.S.gals) of No. 2-D S15 diesel. The engine crankcase holds 10.7 L (11.3 U.S.qts) of API Service Classification CJ-4 oil, and the transmission case takes 60.0 L (63.4 U.S.qts) of KUBOTA SUPER UDT 2 fluid.
How to troubleshoot engine won't start?
A no-start traces to a handful of fuel-side faults. An empty tank, air in the lines, or water in the fuel call for refueling, bleeding, or repair of the fuel system (page G-31). Also check for a clogged fuel filter (page G-36) or a defective supply pump (page 1-S47).
What are the hydraulic system specifications?
Relief valve setting pressure runs 18.9 to 19.8 MPa (192 to 202 kgf/cm2), and safety valve operating pressure runs 23.1 to 24.5 MPa (235 to 250 kgf/cm2). On ROPS models, power steering pump delivery at rated pressure is 23.3 L/min, with an allowable limit of 19.6 L/min.
