This 662-page Kubota L3301, L3901, and L4701 Service Manual is the factory workshop reference for these compact tractors, covered under publication 9Y111-10123. It is built around the D1803-CR-E4 engine used on the L3301 and L3901 and the V2403-CR-E4 engine used on the L4701, both common rail diesels with after treatment.The manual runs the full machine across Information, General, and system sections: engine, clutch, transmission with HST, rear axle, brakes, front axle, steering, hydraulics, and the electrical system with its ECU, sensors, and circuits. Specifications, maintenance check lists, tightening torques, and step by step checking, disassembly, and servicing are included throughout.Owners and independent mechanics can use it to service the diesel engine and DPF, rebuild the transmission, sort out steering or hydraulics, work the brakes, or trace the electrical system. It is delivered as a downloadable PDF you can view on any device or print.

Kubota L3301, L3901, L4701 Common Problems This Manual Covers
Weak transmission or HST drive
Loss of drive, creeping, or poor shifting on the manual or HST models traces to the power train, PTO system, or the hydrostatic transmission assembly. The transmission section covers all of these with mechanism and servicing.
Manual Section: 3 Transmission p. 272Hard starting or DPF warnings
Hard starting, low power, or a regeneration warning on these common rail engines involves the fuel system, EGR, and after treatment. The engine section covers the engine body, fuel system, EGR, and after treatment system with servicing.
Manual Section: 1 Engine p. 135Heavy or unresponsive steering
Stiff or wandering steering points to the hydraulic pump, steering gear box, controller, or cylinder. The steering section documents the linkage, hydraulic circuit, pump, gear box, controller, and cylinder.
Manual Section: 7 Steering p. 496Three-point hitch will not lift
A hitch that lifts slowly or not at all comes from the hydraulic pump, position control valve, safety valve, or the lift cylinder. The hydraulic system section covers the circuit, cylinder, linkage mechanism, control valve, pump, and safety valve.
Manual Section: 8 Hydraulic System p. 531Soft or dragging brakes
Excessive brake pedal free travel or dragging comes from the brake disc, cam plate, or cam adjustment. The brakes section covers the pedal, disc, cam plate, cam, and brake case with checking and servicing.
Manual Section: 5 Brakes p. 442Charging or ECU electrical faults
A flat battery, no start, or warning light can involve the ECU, sensors, switches, or the starting circuit. The electrical system section documents the circuit, instrument panel, electronic control unit, sensors, and starting circuit.
Manual Section: 9 Electrical System p. 577Frequently Asked Questions
