Kubota L305–L355 Series Common Problems This Manual Covers
Hard steering or fluid leak at column
Owners of the L305DT and L345DT often report heavy steering or hydraulic seepage at the steering column. The adjustments section covers setting steering wheel play back to specification.
Manual Section: Adjustments p. 57Three-point hitch will not lift
A hitch that drops or refuses to raise is a frequent complaint on these tractors. The three-point hitch and drawbar section covers the top link, lifting rod, and check chains that set it up correctly.
Manual Section: Three-point Hitch & Drawbar p. 31Engine hard to start or will not crank
A no-crank or slow-start condition often traces to a weak battery or the starter circuit. The troubleshooting section lists causes for an engine that is difficult to start.
Manual Section: Troubleshooting p. 59Engine overheating
Overheating on these Kubota diesels usually comes from restricted radiator airflow or low coolant. The check and maintenance section covers cooling system service and coolant capacities.
Manual Section: Check and Maintenance p. 45Clutch or brake free play out of spec
Dragging clutch or a soft brake pedal means free play has drifted. The adjustments section gives the clutch and brake free play settings, both specified at 25 to 35 mm.
Manual Section: Adjustments p. 57Poor traction from wrong tread or ballast
Instability or slip is often a tread, tire, or ballast setup issue rather than a fault. The wheels, tires and tread section covers tread settings for 2WD and 4WD, ballast, and toe-in.
Manual Section: Wheels, Tires and Tread p. 33Frequently Asked Questions
