Kubota M115GX-3 Utility Tractor Parts Manual

The Kubota M115GX-3 is a mid-size utility tractor that usually lives on real farms doing loader work, hay, and tillage, not lawn duty. The Kubota M115GX-3 parts manual is what you grab when you’ve got the tractor half apart and you need to see every washer, seal, and bracket in an assembly. I’ve seen owners use it to plan winter rebuilds, and parts guys use it daily to make sure they’re pulling the exact right bits before you drive in from the field. If you’re trying to fix something step-by-step, that’s the service manual, not this.

What this manual helps you do

• Identify every component in the engine, transmission, axles, hydraulics, PTO, 3-point, and electrical system by exploded diagrams and callouts.
• Locate the correct OEM Kubota part number for worn items like seals, bushings, filters, linkages, and harness pieces before you order.
• Look up quantity-per-machine for bolts, nuts, gaskets, and o-rings so you don’t come up one short in the middle of a repair.
• Cross-reference older part numbers to newer superseded numbers, helped by the two included revisions (BKIDK5153 and BKIDK5155).
• Verify that a replacement part on the bench actually matches what belongs on your specific M115GX-3 before you bolt it back together.

Who this is for

This parts manual fits an independent ag mechanic, farm owner-operator, Kubota dealer parts staff, or anyone maintaining a small fleet of orange utility tractors. If you need torque specs, test procedures, or “how to split the tractor” instructions, you want the Workshop/Service Manual instead, not this parts catalog.

FAQ

Q: Does this cover the engine, hydraulics, PTO, and 3-point hitch assemblies?

A: Yes, this type of Kubota parts manual normally shows exploded views and part numbers for all major assemblies, including engine, hydraulics, PTO drive, and 3-point hitch.

Q: Are the part numbers up to date, or will I still have to chase supersessions at the dealer?

A: The listing includes two revisions (BKIDK5153 and BKIDK5155), so most Kubota superseded numbers are shown, though your dealer can always confirm the latest updates.

Bottom line: If you’re ordering or matching parts for an M115GX-3, this is the right book; if you’re chasing repair procedures or specs, keep looking for the WSM.
