Common Kubota M120 Problems:

1. Stalling Issues When Cold:

Ah, the early morning struggles with starting the M120! Many times, I’ve found it stalling like a stubborn mule when the engine is cold. Thankfully, there’s a quick DIY fix for this.

Ensure your glow plugs are in good shape – these bad boys warm up the combustion chamber for a smoother start. If the issue persists, you might want to call in a professional to inspect the fuel system and injectors.

DIY Solution: Check and replace glow plugs if needed. Warm up the engine for a few minutes before engaging in heavy work.

Professional Solution: Call your trusted mechanic to examine the fuel system, injectors, and overall engine health.

2. Hydraulic Woes:

Here’s a head-scratcher for you – wonky hydraulics. If your M120’s hydraulic system is feeling sluggish or acting up, it might be due to low hydraulic fluid or a clogged filter. DIY remedy?

Check the fluid levels and replace the filter if it’s seen better days. But if the issue persists, it’s time to invite a professional over for a thorough hydraulic system check.

DIY Solution: Check hydraulic fluid levels and replace the filter if needed.

Professional Solution: Call a hydraulic system expert to diagnose and fix any major issues.

3. Electrical Gremlins:

Let’s talk about the quirky world of electrical problems. If you find lights flickering or the starter refusing to cooperate, it could be a faulty battery, corroded connectors, or a failing alternator.

Here’s a little tip from yours truly – start with the battery connections. A little cleaning and tightening might do the trick. But if sparks are still flying (figuratively, of course), it’s time to bring in an electrically savvy friend or a professional.

DIY Solution: Clean and secure battery connections.

Professional Solution: Seek assistance from an expert in electrical systems.
