Kubota M135GX Utility Tractor Parts Manual

The Kubota M135GX is a mid-size utility tractor that usually lives on row-crop, hay, and loader work. The Kubota M135GX parts manual is what the parts desk, independent mechanics, and farm owners grab when they’re trying to name a broken piece and get it on order before the tractor sits through planting or harvest. If you’re staring at a worn seal, bent link, or mystery fitting and need the Kubota OEM number, this is the book. It’s not for how to fix it, it’s for exactly what to buy.

What this manual helps you do

• Identify the correct OEM part number for engine, transmission, axle, PTO, hydraulics, and electrical components on the M135GX.
• Locate small pieces in assemblies—pins, shims, seals, O-rings, brackets—using exploded diagrams so you don’t guess at what’s missing.
• Look up quantity-per-tractor for bolts, gaskets, and bearings before you tear down a front axle, 3-point hitch, or hydraulic valve stack.
• Cross-reference older Kubota numbers to updated ones, using both included revisions (BKIDK5025 and BKIDK5026) so you see superseded parts.
• Verify that the parts you’re about to order actually match your M135GX configuration, cutting down on wrong shipments and downtime.

Who this is for

This parts manual fits an independent ag mechanic, farm owner-operator, Kubota dealer parts staff, or anyone managing a small fleet of orange utility tractors. If you’re after torque specs, hydraulic pressures, or step-by-step repair procedures, you want the Kubota Workshop/Service Manual instead, not this parts catalog.

FAQ

Q: Does this cover the engine, hydraulics, PTO, and 3-point hitch on the M135GX?

A: Yes, a Kubota M135GX parts manual normally diagrams all major assemblies, including engine, hydraulics, PTO drive, and 3-point hitch components.

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

A: The manual includes revisions BKIDK5025 and BKIDK5026, so you’ll see many of Kubota’s own superseded numbers and updated replacements listed.

Bottom line: If you already know how to wrench and just need the right Kubota part numbers and diagrams for an M135GX, this is the right manual; if you need “how-to” repair steps, keep looking for the Workshop Manual.
