Part of the Kubota Repair Manuals.
This Kubota Service Manual covers the M7580, M8580, and M9580 tractors in one 561-page volume, built around the V4302 and V4702 engines.It runs from tractor mechanism and identification through engine, clutch, transmission, rear axle, brakes, front axle, steering, hydraulics, electrical, and the operator platform. Each section gives troubleshooting, servicing specifications, and tightening torques, along with the fluid capacities, valve clearance, torque values, and free-play settings you need. Model differences, such as the larger fuel tank and PTO clutch on the M9580, are called out where they matter.It downloads as a text-searchable PDF, so you can move straight to the engine, transmission, hydraulic, or electrical section on a phone, tablet, or shop computer and print only the pages a job requires.

Kubota M7580, M8580, M9580 Common Problems This Manual Covers
Clutch slip or drag
A worn travelling clutch slips under load, while a dragging PTO clutch makes the PTO hard to engage. The Clutch section covers travelling-clutch, PTO-clutch, and Bi-Speed Turn troubleshooting and specifications.
Manual Section: Sect 2 Clutch p. 328Shuttle transmission shifting problems
Hard or noisy shifting in the synchromesh or IC shuttle transmission points to worn synchronizers or linkage. The Transmission section covers troubleshooting and dual-speed and Bi-Speed Turn servicing.
Manual Section: Sect 3 Transmission p. 344Weak three-point hitch or hydraulics
Low hydraulic pressure or a worn pump leaves the three-point hitch slow or unable to lift. The Hydraulic section covers the pump, relief valve, cylinder safety valve, and control linkage.
Manual Section: Sect 8 Hydraulic p. 458No-start or charging faults
A failing charging system, key switch shut-off circuit, or starting system leaves the tractor dead or with a flat battery. The Electrical section covers battery, starting, charging, and lighting troubleshooting.
Manual Section: Sect 9 Electrical p. 486Engine power loss or hard starting
Worn valves, incorrect clearance, or low compression cause weak power and hard starting. The Engine section covers troubleshooting, servicing specifications, valve timing, and the lubricating system.
Manual Section: Sect 1 Engine p. 274Heavy or unresponsive steering
A worn power-steering controller or low hydraulic supply makes the wheel heavy. The Steering section covers troubleshooting, servicing specifications, tightening torques, and checking.
Manual Section: Sect 7 Steering p. 450Frequently Asked Questions
