Kubota F3680 Front Mower Workshop Manual

The Kubota F3680 is a front-mount diesel mower that spends its life chewing through turf around farms, campuses, and big properties. When something in that driveline, steering, or hydraulic lift quits in the middle of mowing season, this is the kind of workshop manual I grab out in my shed. Folks reach for a WSM when they're past basic filters and belts and need to open up housings, trace wiring, or set things back to factory spec. If you're trying to keep an F3680 working without dragging it to the dealer every time, this is the right level of book.

What this manual helps you do

• Trace and diagnose electrical issues with the F3680's wiring, switches, safety interlocks, and charging system.
• Check and adjust engine-related items like fuel system components, governor linkages, and valve-related settings.
• Follow step-by-step teardown and reassembly on the front axle, steering components, and drivetrain.
• Troubleshoot hydraulic and power steering problems, then pressure-test and replace pumps, valves, or cylinders as needed.
• Set and verify mower deck lift, linkages, and related controls so the front mower cuts level and runs safely.

Who this is for

This is aimed at an owner-operator, small contractor, or shop mechanic who actually spins wrenches and wants dealer-level procedures on an F3680. If you only need basic controls, maintenance intervals, or how to run the mower, you want the operator's manual instead, not this workshop book.

FAQ

Q: Is this a searchable PDF, and can you read the wiring diagrams clearly?

A: Yes, it's a PDF and you can search text; wiring diagrams are clear enough to zoom and follow circuits.

Q: Does this cover my specific F3680 year or variant?

A: It's written for the F3680 front mower as a model; as long as your machine is an F3680, this manual should match it more or less exactly.

Q: Is this the right document if I'm doing major repairs?

A: Yes, this is the workshop manual, which is what you want for teardown, specs, and diagnostics, not just routine service.

Bottom line, if you own or maintain a Kubota F3680 front mower and plan to do real repairs instead of just oil changes, this is the manual you want. If you don't wrench on your own equipment, you can skip it.
