Kubota B6000, B6000E, B6000E-T Common Problems This Manual Covers
Weak or erratic hydraulic lift
Hydraulics that lift slowly or drop after service are a recurring B6000 complaint, often from low or contaminated oil, a clogged filter, or worn parts. The hydraulic system section covers the lift, control valve, and relief pressure.
Manual Section: Hydraulic System p. 38Front wheels stop driving on 4WD
On 4-wheel-drive B6000 tractors the front axle can quit sending power to the front wheels. This section details the front axle structure, disassembly, and assembly so you can find the worn component.
Manual Section: Front Axle p. 22PTO output problems
A PTO that will not turn implements at the right speed usually points to shaft or drive wear. The PTO section gives the shaft diagram, RPM figures, and specifications for checking it.
Manual Section: PTO p. 41Clutch slipping or dragging
Incorrect pedal play or a worn clutch leaves the B6000 hard to shift or slow off the line. The clutch section covers adjustment of the clutch and brake pedals and the differential lock pedal.
Manual Section: Clutch p. 28Hard starting from battery or starter
Slow cranking or no start often traces to the battery, starter, or magnetic pump on these older diesels. This section covers checks and repair of the battery, starter, and related electrical parts.
Manual Section: Battery p. 16Excessive steering play
Loose or wandering steering is common wear on a decades-old tractor. The steering handle section covers the gear case, steering shaft, sector shaft, and pitman arm so you can restore tight control.
Manual Section: Steering Handle p. 26Frequently Asked Questions
