Kubota L3200, L3800 Common Problems This Manual Covers
Hard starting or low power
Diesel L3200 and L3800 tractors can start hard or lose power when the fuel system, injectors, or valve clearance drift. The Engine section covers the fuel system, servicing specifications, and adjustments.
Manual Section: Engine p. 82Clutch slip or drag
A slipping or dragging clutch makes shifting difficult and wastes power. The Clutch section covers structure, adjustment, and separating the clutch housing from the engine.
Manual Section: Clutch p. 163Weak HST or shifting trouble
Sluggish HST travel or shifting problems trace to the drivetrain. The Transmission section covers both manual and HST types, including the power train, PTO system, and shift linkage.
Manual Section: Transmission p. 193Slow or weak three point hitch
A slow, weak, or drifting hitch usually points to the hydraulic pump or cylinder. The Hydraulic System section covers the pump, three point hitch system, and hydraulic circuits.
Manual Section: Hydraulic System p. 357Poor or uneven braking
Weak or uneven braking can come from worn friction surfaces or misadjusted linkage. The Brakes section covers operation, features, and servicing with the correct free travel.
Manual Section: Brakes p. 303Steering play or hard steering
Excess play or heavy steering can come from the steering gear box or hydraulic circuit. The Steering section covers its structure, operation, and hydraulic circuit.
Manual Section: Steering p. 339Charging or instrument faults
Charging faults, dead lights, or a blank meter panel are traced through the wiring. The Electrical System section provides wiring diagrams and covers the instrument panel and Easy Checker.
Manual Section: Electrical System p. 401Frequently Asked Questions
