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.
