This is the Kubota factory service manual for the M4700, M5400, and M5400DT-N tractors, powered by the F2803-LA and F2803-A diesel engines (publication 11790). Its 442 pages cover the engine, the travelling clutch, the transmission, the front and rear axles, the brakes, the power steering, and the hydraulic system, plus the electrical system and a supplement for the narrow M5400DT-N.Each section gives mechanism descriptions, servicing specifications, tightening torques, and step-by-step disassembly and reassembly. That lets you chase down a tractor that will not shift into gear, bleed a hydraulic system that went weak after service, check valve clearance and engine oil pressure, or set the clutch pedal free play. It is a downloadable, printable PDF matched to the M4700, M5400, and M5400DT-N.

Kubota M4700, M5400, M5400DT-N Common Problems This Manual Covers
Will not shift into gear
Owners report the tractor will not shift into gear, then works again after the shift linkage is adjusted or repositioned. The Transmission section covers the travelling system, shift linkage mechanism, and structure.
Manual Section: Sect 3 Transmission p. 168Hard shifting or gear engagement trouble
Difficult gear engagement usually traces to shift linkage wear or misalignment. The Transmission section documents the main gear shift, shuttle shift, and shift linkage sections for adjustment.
Manual Section: Sect 3 Transmission p. 168Hydraulic weak or sluggish after service
The hydraulic system can lose function or feel weak when air remains in it after maintenance, requiring a proper bleed. The Hydraulic section covers the pump, relief valve, and position control valve.
Manual Section: Sect 8 Hydraulic p. 306Overheating stall from clutch seal failure
Overheating and stalling under load is sometimes linked to failed clutch seals. The Clutch section covers the travelling clutch, its linkage, and operation.
Manual Section: Sect 2 Clutch p. 134Heavy power steering
A heavy steering wheel points to the power steering pump, relief valve, or steering controller. The Steering section covers the pump test, controller removal, and disassembly.
Manual Section: Sect 7 Steering p. 276No-start or charging fault
A no-start or weak charging can come from the battery or starting system. The Electrical section provides troubleshooting, servicing specifications, and disassembly of the battery and starting system.
Manual Section: Sect 9 Electrical p. 354Brake pedal problems
A soft or poorly returning brake pedal points to the brake case components. The Brakes section covers the brake pedal, brake case, and its disassembly.
Manual Section: Sect 5 Brakes p. 234Frequently Asked Questions
