Part of the Kubota Operator Manuals.
This is the operator manual for the Kubota M5660SUH and M5660SUHD tractors, built around the V2403-CR-TE4 diesel engine with a Diesel Particulate Filter aftertreatment system. Across 115 pages it walks the owner through safe operation, daily and periodic servicing, and the controls that make these machines work day to day.You get the full specification tables, PTO and 3-point hitch operation, hydraulic unit setup, tire pressures and ballast, plus DPF regeneration procedures and service intervals. Torque values, fluid capacities, and maintenance schedules are all here.If you own or service an M5660SUH or M5660SUHD, this PDF gives you the manufacturer procedures for starting, operating, maintaining, and storing the tractor, along with a troubleshooting section for common engine complaints.

Kubota M5660SUH, M5660SUHD Common Problems This Manual Covers
Engine hard to start or stalls
Fuel or air delivery problems and skipped daily checks leave the engine cranking without firing or dying shortly after startup. The troubleshooting section lists the checks for hard starting, insufficient power, and sudden stalls.
Manual Section: Troubleshooting p. 111DPF regeneration not completing
Owners of these Tier 4 machines run into blocked or interrupted regeneration when idling too long or ignoring warning prompts. The engine operation section covers the DPF muffler, regeneration procedure, and PM warning levels.
Manual Section: Operating the Engine p. 34PTO will not engage cleanly
Interlocks, incorrect lever positions, or a mishandled clutch keep the PTO from engaging or disengaging as expected. The PTO section explains the clutch control lever, indicator, speed limiter, and shaft cover.
Manual Section: PTO p. 63Tractor rolls when parked
Leaving the transmission in gear instead of setting the parking brake lets the tractor move on a slope. The safe operation section spells out the correct parking and shutdown sequence.
Manual Section: Safe Operation p. 11Weak or slow 3-point hitch
Sluggish or erratic lift response often traces to control settings or hydraulic adjustment rather than a failed pump. The hydraulic unit section covers position control, float control, and lowering speed.
Manual Section: Hydraulic Unit p. 70Overheating or fluid leakage in service
Missed fluid checks, overfilling, or servicing on uneven ground lead to overheating and spills. The periodic service section lays out the daily and interval checks for oil, coolant, and the water separator.
Manual Section: Periodic Service p. 86Loose brakes, clutch, or linkage
Wear and missed inspections leave brakes, clutch, and linkage pins feeling loose or out of adjustment. The maintenance section sets the service intervals and inspection points for these wear parts.
Manual Section: Maintenance p. 81Frequently Asked Questions

It covers the Kubota M5660SUH and M5660SUHD tractors, both powered by the V2403-CR-TE4 diesel engine. It is the factory operator manual for these two models.
How do I run a DPF regeneration on the M5660?
The Operating the Engine section covers the Diesel Particulate Filter muffler, the regeneration operating procedure, and the PM warning levels that tell you when parked regeneration is required. p. 34
What are the wheel bolt torque specs?
The Tires, Wheels and Ballast section gives rear wheel bolt torque of 260 to 304 N-m (192 to 224 ft-lbs) as standard, with steel-disk tire-specific values, and front axle mounting bolt torque separately. p. 74
Does the manual include maintenance intervals and fluid capacities?
Yes. The Maintenance and Specifications sections list service intervals, engine oil, coolant and fuel capacities, and the engine oil, hydraulic filter, and coolant change schedules. p. 81
