Kubota M6040–M9540 Series Common Problems This Manual Covers
Tractor will not start
A no-start or intermittent start often comes down to the starting procedure, seat and interlock conditions, or a daily check that was missed. The Operating the Tractor section walks through correct starting.
Manual Section: Operating the Tractor p. 24Hydraulics feel slow or weak
Sluggish or weak hydraulics usually mean low fluid, a control valve set wrong, or air in the system. The Hydraulic Unit section explains the remote hydraulic control system and its valve levers.
Manual Section: Hydraulic Unit p. 34PTO does not engage or turn off
A PTO that will not engage, slips, or fails to stop is often a control lever, switch, or clutch indicator issue. The PTO section covers the gear shift lever, clutch control lever and switch, and the indicator.
Manual Section: PTO p. 29Blown fuse or dead light
A dead accessory or lighting circuit is commonly a blown fuse or a failed bulb. The Maintenance section shows how to replace a fuse and a light bulb as service-as-required tasks.
Manual Section: Maintenance p. 39Loose wheel bolts or low tire pressure
Wheel bolts that back off or tires run at the wrong pressure affect handling and safety. The Tires, Wheels and Ballast section gives inflation pressure and wheel bolt torque figures.
Manual Section: Tires, Wheels and Ballast p. 36Confusing warning or monitor message
An unfamiliar indicator or LCD monitor message can stop work until you know what it means. The Instrument Panel and Controls section identifies the monitor, indicators, and control layout.
Manual Section: Instrument Panel and Controls p. 18Frequently Asked Questions
