Kubota ST-30 Compact Tractor Parts Manual (BKIDK0310)

The Kubota ST-30 is a compact tractor, the kind that ends up doing mowing, loader work, and light field chores on small farms and estates. The Kubota ST-30 parts manual is what parts counters, independent shops, and owners reach for when they’re chasing a leaking seal, a busted linkage, or planning a front axle or PTO teardown. You use this book when you want to see exactly how things stack together and what to call the part when you order it. You do not use it for how‑to repair steps or torque specs.

What this manual helps you do

• Identify every nut, bolt, seal, and casting on the ST-30 using exploded diagrams of the engine, transmission, axles, hydraulics, PTO, and 3‑point hitch.
• Locate where a specific part actually lives on the tractor, so you’re not guessing which O‑ring or bushing to order before you split or strip an assembly.
• Look up the correct Kubota OEM part number for worn items like steering joints, brake parts, glow plug wiring bits, and HST‑related hardware.
• Cross-reference older Kubota ST-30 part numbers to the newer superseded numbers that most parts desks usually stock now.
• Verify the quantity of fasteners, shims, and gaskets you’ll need so you can order everything in one shot before a weekend repair.

Who this is for

This parts manual is aimed at an independent ag mechanic, a farm owner‑operator, Kubota dealer parts staff, or anyone keeping an older ST-30 working. If you need torque values, wiring test procedures, HST troubleshooting, or adjustment specs, you want the Workshop Service Manual, not this parts catalog.
