Three tractors live inside this 442-page Kubota M4700/M5400 Service Manual PDF (OEM #11790): the M4700, M5400, and M5400DT-N, documented from engine rebuild through full electrical diagnosis. Hydraulic schematics trace fluid through the PTO clutch valve and position control circuit. Twenty pages of wiring diagrams map the charging, starting, and lighting circuits, while more than 100 pages of disassembly procedures sit next to exploded views. Troubleshooting charts cover every drivetrain fault, from transmission and brakes to front and rear axle, steering, and hydraulics, with 10 pages of factory torque specs alongside. Need the shift fork to shifter groove clearance? It's 0.13 to 0.40 mm. Hydraulic pipe mounting screws? 17.7 to 20.6 N·m. Built-in bookmarks drop you straight onto the section you want, so the number is on screen before you reach for a wrench.

Kubota M4700, M5400, M5400DT-N Common Problems This Manual Covers
Kubota M5400 won't shift into gear or intermittently locks out during field operation p. 183
Check the shift linkage mechanism under the shifter assembly for wear and misalignment. The shift fork to shifter groove clearance should measure 0.13 to 0.40 mm per the factory spec on page 183. Adjust linkage rods until all neutral positions align cleanly. Test every gear selection before buttoning it back up.
Manual Section: Transmission TroubleshootingHydraulic system sluggish or implement won't lift after fluid service or repair p. 334
Verify the relief valve setting pressure after any hydraulic service; factory spec is 18.6 to 19.1 MPa (page 334). Torque all hydraulic pipe mounting screws to 17.7 to 20.6 N·m (page 335). Cycle the implement controls 10 to 15 times with the engine running to purge trapped air before measuring lift performance.
Manual Section: Hydraulic System TroubleshootingTractor overheats and stalls under heavy load, clutch pedal engagement feels wrong p. 26
Inspect the travelling clutch adjustment before pulling anything apart. Clutch pedal free play must be 35 to 45 mm per the spec on page 26. If adjustment is correct but the machine still overheats and drags, disassemble the clutch and inspect seal rings for wear or hardening. A dragging clutch will rob power and spike temperatures under sustained load.
Manual Section: Travelling Clutch TroubleshootingGears grind or clash when shifting, hard to get tractor through gear changes p. 183
Remove the transmission cover and inspect all shift forks and rods for wear, bending, or binding. Measure shift fork to shifter groove clearance; factory specification on page 183 is 0.13 to 0.40 mm. Replace any fork worn past tolerance. Lubricate shift rod O-rings and check detent balls and springs for fatigue or deformation.
Manual Section: Transmission TroubleshootingEngine won't start or turns over slowly in cold weather conditions p. 81
Test battery voltage and bleed any air from the fuel system at the inline filter before cranking. If the engine fires but runs rough or smokes, inspect valve clearance with the engine cold: spec is 0.18 to 0.22 mm (page 81). Once running, confirm oil pressure holds at least 98 kPa at idle (page 85).
Manual Section: Engine TroubleshootingFrequently Asked Questions
What do Kubota M5400 error codes mean?
Rather than "error codes," the manual lists "Indication Items" or "Warning Lamps" on the Easy Checker panel. The fuel level lamp lights when remaining fuel drops below roughly 10 L (2.6 U.S.gal., 2.2 Imp.gal.); the engine oil pressure lamp flags low oil pressure. A charging circuit fault shows up when both of those lamps light at once.
What is the torque spec for Kubota M5400 head bolts?
On the Kubota M5400, the cylinder head screws (M11 x 1.25) take a tightening torque of 93.1 to 98.0 N·m (9.5 to 10.0 kgf·m, 68.7 to 72.3 ft-lbs). Apply engine oil to their threads and seats first, before you tighten them.
What is the torque spec for Kubota M4700 wheel lug nuts?
On the Kubota M4700, front wheel mounting nuts torque to 166.7 to 196.1 N·m (17.0 to 20.0 kgf·m, 122.9 to 144.6 ft-lbs). Rear wheel mounting nuts go to 260 to 304 N·m (26.5 to 31.0 kgf·m, 192 to 224 ft-lbs). Check all of them often and keep them tight, especially while the tractor is new.
What are the replacement specifications for shift linkage components?
Between the shift fork and shifter groove, the allowable clearance limit is 0.8 mm (0.031 in.), while the factory specification runs from 0.13 to 0.40 mm (0.0051 to 0.0157 in.). Once a measurement passes that allowable limit, the worn components should be replaced.
How will I receive this Kubota M4700, M5400, M5400DT-N Service Manual?
Right after checkout, a 442-page searchable PDF downloads to your device. Open it on a laptop, tablet, or phone and carry it straight onto the shop floor.
Can I print this Kubota M4700, M5400, M5400DT-N manual?
No limits here. The PDF ships DRM-free, so print whatever sections you want to carry out to the shop. Standard letter or A4 paper both work fine.
Are electrical wiring diagrams included in this Kubota M4700, M5400, M5400DT-N?
Yes. Full wiring diagrams come included, mapping every electrical circuit, harness route, and connector pinout across the Kubota M4700, M5400, and M5400DT-N.
