Kubota M135GX Tractor Workshop Manual

The Kubota M135GX is a big utility-tractor-class machine for tillage, hay work, loader work, and general farm chores. People reach for this workshop manual when the tractor is out of warranty and they want dealer-level repair info without dealer bills. Around my place, that means winter tear-downs so the tractor is ready when planting or hay season hits and downtime is expensive.

What this manual helps you do

• Diagnose hydraulic issues, check pressures, and trace problems with the three-point hitch or remote valves
• Follow step-by-step teardown and reassembly on the M135GX engine, including timing and internal inspections
• Troubleshoot HST or powershift / transmission driveline problems, and set clearances and linkages correctly
• Trace and repair wiring faults, read full schematics, and verify sensor and switch circuits on the tractor
• Replace front axle, steering, PTO, and brake components with the right sequences and torque references

Who this is for

This is for an owner-operator, farm shop, or small contractor running an M135GX who wants to do real repairs, not just fluid changes. If you only need basic controls, safety, and maintenance intervals, you want the operator's manual instead, not this workshop manual.

A: It is written for the M135GX tractor line; if your serial tag says M135GX, this is the right style of manual, regardless of minor year updates.
