This Kubota workshop manual covers the L2250, L2550, L2550 GST, L2850, L2850 GST, and L3250 compact diesel tractors, including the D1302-DI-A, D1402-DI-A, V1702-DI-A, and V1902-DI-A engines. Across 626 pages it walks through the engine, clutch, transmission, hydraulics, steering, brakes, and the full electrical system, plus separate servicing sections for the GST hydraulic shuttle transmission that sets the L2550 GST and L2850 GST apart from the dry-clutch models.
You also get factory torque values, clearances, and step by step disassembly for the front axle, three-point hitch, and mounted implements like the front-end loader, mower, and rotary tiller. Whether you are rebuilding an engine, chasing a charging fault, or resetting clutch free play, this is the same reference a Kubota technician works from. Delivered as an instant PDF download you can read on any device or print for the shop.
