This Kubota M4900, M5700 Workshop Manual (OEM #97897-12460) covers one machine family: the M4900 and M5700 tractors in 2WD, 4WD, and Cabin trim. Wiring diagrams run for both ROPS and Cabin types. Hydraulic schematics map the three-point lift circuit, power steering pump, and auxiliary control valve. A 100-page block of exploded views spans every major assembly, and the torque tables cover each fastener from engine head bolts to transmission case hardware. Ten pages of troubleshooting charts walk through engine, clutch, transmission, brakes, hydraulics, electrical, and cabin A/C faults. Refill figures are spelled out too: 40.0 L for the M4900 transmission, 43.0 L for the M5700, and 8.0 L in the engine crankcase before you turn the key. Bookmarked by section and searchable by keyword, so you pull up the right page on your phone and get back to work.

Kubota M4900, M5700 Common Problems This Manual Covers
Kubota M4900 M5700 diesel won't start or cranks slowly after sitting overnight in cold p. 89
Check the glow plug circuit: confirm each plug draws current and the relay fires on key-on. Measure compression per page 93; factory minimum is 3.53 MPa (512 psi). If compression holds, crack an injector line while cranking to confirm fuel reaches the pump. Air in the lines or a clogged filter are the usual cold-start culprits.
Manual Section: Engine TroubleshootingEngine temperature gauge climbs into the red during mid-day field work, overheating alarm p. 89
Inspect fan belt tension first; deflection should sit at 7 to 9 mm (0.28 to 0.35 in.) per page 34, since a loose belt drops cooling output fast. Check coolant level and condition next: the system holds 7.3 L (7.7 U.S.qts.) and wants a flush every 2 years per page 26. If both pass, clear the radiator core of debris blocking airflow.
Manual Section: Engine TroubleshootingClutch slips under heavy drawbar load or won't fully disengage when pedal is depressed p. 155
Measure clutch pedal free play before anything else; spec is 35 to 45 mm (1.4 to 1.8 in.) per page 30. Play outside that window drives both dragging and slipping. With adjustment correct and the fault still there, pull the clutch housing per page 155 and check the disc for glazing or heat cracks.
Manual Section: Clutch TroubleshootingThree-point hitch won't lift to full height or slowly drops with implement attached p. 315
Verify hydraulic oil level, then look for contamination or metal debris in the filter. Hook up a pressure gauge and read pump output; low pressure points to a worn pump or a failed relief valve. Since transmission fluid wants changing every 600 hours per page 26, degraded oil often explains sluggish lift.
Manual Section: Hydraulic System TroubleshootingFront wheels wander or pull to one side on the road, hard to hold a straight line p. 252
Gauge front toe-in: 2WD runs 1 to 5 mm (0.04 to 0.20 in.), 4WD runs 2 to 8 mm (0.08 to 0.32 in.) per page 36. Toe out of spec scrubs tires and lets the front wander. Check kingpin bearings and tie rod ends for play before you adjust; worn joints won't hold the setting.
Manual Section: Front Axle TroubleshootingGears slip out of engagement under load or shifting between ranges requires excessive force p. 191
Drain a fluid sample and look for metal particles or milky contamination. Low or degraded oil is the top cause of hard shifting on these tractors. Fluid wants changing every 600 hours per page 26. If the oil checks out, inspect shift linkage geometry and detent spring tension using the disassembly steps from page 191.
Manual Section: Transmission TroubleshootingFrequently Asked Questions
What are the recommended service intervals?
Service intervals are laid out in a full table. Engine oil gets its first change at 50 hours, then runs on a regular replacement cycle. The engine oil filter follows the same 50-hour break-in, then swaps out during routine service. Front axle oil also takes its first change at 50 hours.
What fluids and capacities does this machine require?
Each system takes a specific fluid and volume. The M4900 fuel tank holds 65.1 L (17.2 U.S.gals., 14.3 Imp.gals.); the M5700 (CAB) holds 95.1 L (25.1 U.S.gals., 20.9 Imp.gals.). Engine oil capacity is 8.0 L (8.5 U.S.gals., 7.0 Imp.qts.), and the M4900 transmission case takes 40.0 L (42.3 U.S.gals., 35.2 Imp.gals.).
How to troubleshoot engine won't start?
When the engine won't start, the usual suspects are no fuel, air in the fuel system, or water in the fuel system. The fixes match: top off fuel, bleed the lines, or clean the affected components. A clogged fuel pipe or filter, incorrect injection timing, or a discharged battery can also be to blame.
What are the hydraulic system specifications?
The M4900 hydraulic pump runs at roughly 2600 rpm with a rated pressure of 19.1 MPa (195 kgf/cm², 2773 psi). Target oil temperature falls between 45 to 55 °C (113 to 131 °F). Bushing to gear shaft clearance should hold at 0.15 mm (0.0059 in.).

Yes. Print as many copies as you want, with no restrictions. Plenty of mechanics print just the section they need and carry it to the shop floor.
Does this Kubota M4900, M5700 Workshop Manual cover the hydraulic system?
Yes. Full hydraulic diagrams are included, covering circuits, valve locations, and component specs for the Kubota M4900, M5700.
Document Quality
This document is a scanned PDF with an OCR text layer, allowing you to search and copy text. The text is generally clear and readable, though it may not be as crisp as native digital documents, with some minor pixelation visible. Diagrams and illustrations are raster images, and their labels are mostly readable, but some fine details might require zooming. Pages are largely clean, showing typical scan characteristics like occasional minor specks or slight background variations. You will find many blank pages throughout the document, which are likely blank reverse sides from the original physical manual.
