This Kubota workshop manual covers the M4000, M4500, M5500, M6500, and M7500 tractors, built with Kubota's S2200, S2600, D3000, V4000L, and V4000 diesel engines. Its 404 pages document the disassembly, servicing, and reassembly of the whole machine.
Coverage runs from preparatory teardown steps and full engine service, including the cylinder head, injection pump, pistons, and timing gears, through the tractor body: front axles in two and four wheel drive, the clutch, and the steering system. Further sections detail the hydraulic system and pump and the complete electrical system, including battery servicing, charging, and starting.
You get servicing specifications, torque values, and clearances for each engine and model variant, making this the reference for a major repair or rebuild. It is a dealer-level service document for owners and mechanics working on these older M series Kubota tractors, not a basic operator manual.
