Kubota M4900–M6800 Series Common Problems This Manual Covers
Kubota M5700 implement not rising or lowering after changing the hydraulic fluid and filter
Inspect the hydraulic oil filter installation. Replace the filter every 300 hours, as noted on page 26. Verify the gasket seats fully so the system cannot draw air. Tighten the main delivery pipe retaining nut to 46.6 to 50.9 N·m (34.4 to 37.6 ft-lbs) for a complete seal.
Manual Section: Hydraulic System TroubleshootingShuttle shift lever feels excessively stiff or binds completely when shifting between forward and reverse
Check the shuttle shift linkage for binding and wear. Measure the shuttle shift rod and set its length to about 160 mm (6.3 in.), per page 205. On reassembly, torque the shuttle case assembly screw nuts to 23.5 to 27.4 N·m (17.4 to 20.3 ft-lbs).
Manual Section: Transmission TroubleshootingTravelling clutch slips under load, chatters during engagement, or exhibits severe vibration at high RPM
Measure the clutch pedal free play as shown on page 166 and adjust the linkage to hold 35 to 45 mm (1.4 to 1.8 in.) of clearance. Inspect the clutch disc for wear. Torque all clutch mounting screws to 23.5 to 27.5 N·m (17.4 to 20.3 ft-lbs).
Manual Section: Clutch Troubleshooting (Travelling Clutch)Engine idles rough, lacks power under heavy draft loads, or stalls completely in the field
Drain the fuel system and inspect the lines for restrictions. Replace the fuel filter element every 400 hours, per page 26. Confirm engine oil pressure at idle speed reads at least 98 kPa to rule out internal wear before the machine goes back to work.
Manual Section: Engine TroubleshootingFrequently Asked Questions
How to reset the Kubota M4900/M5700 fuel system after filter change?
After a filter change, bleed the fuel system with the fuel cock open. On CAB models, pump the fuel pump knob until you feel resistance, then start the engine at mid-speed (around 1500 min-1 rpm) and accelerate to clear the air. On ROPS models, open the fuel cock, start the engine, and let it run about 30 seconds before shutting down.
How to reset the Kubota M5700 hydraulic shuttle if it squeals or won’t engage?
When the M5700 hydraulic shuttle won't engage cleanly, measure the clearance between the internal snap ring and the pressure plate. On serial numbers M5700-53536 and below, factory spec is 1.8 to 2.0 mm (0.071 to 0.079 in.), with an allowable limit of 3.6 mm (0.142 in.). If clearance falls outside that limit, correct it by combining clutch discs.
How to reset a Kubota M4900 no-start or hard-start condition?
A no-start or hard-start usually traces to fuel: replenish if empty (page G-29), bleed trapped air (page G-29), or change a clogged fuel filter (page G-23). A discharged battery needs recharging. Starter or main switch faults call for repair or replacement, detailed on pages 9-S11 to S14 and 9-S5 to S7 respectively.
How to reset Kubota warning lights or fault indicators on M-series tractors?
Warning lights and fault indicators reset only after you clear the root cause. Take the 'Fuel Limit and Charging Lamp' that stays on while the engine runs: it points to a short circuit between the alternator L terminal lead and chassis, or a failed alternator. Repair or replace as detailed on pages 9-M1 to M25 or 9-S15 to S20.
How quickly can I access this Kubota M4900–M6800 Series manual after buying?
Immediate download of the complete 741-page searchable Service Manual. Open it on any device: laptop at your desk, phone out in the field.
Is this Kubota M4900–M6800 Series Service Manual printable?
None at all. The PDF is DRM-free, so print whatever sections you need for the shop. Standard letter or A4 paper works.
Are electrical wiring diagrams included in this Kubota M4900–M6800 Series?
Complete wiring diagrams are included, covering all electrical circuits, harness routing, and connector pinouts for the Kubota M4900–M6800 Series.
