Why Won't My Tractor Start? (Part 1)

There are a few things that can contribute to your Chinese tractor not starting properly or possibly not starting at all. In this post we will discuss the electrical side of starting your tractor and the common problem areas to troubleshoot. This isn’t an exhaustive list, but it does account for around 90% of the problems we see.

Troubleshooting a Tractor that Won’t Start

If you’re getting absolutely no power to your starter (nothing at all happens when you turn the ignition key), then you’re having an issue in the circuit which sends electricity to the solenoid. The first thing to check is your clutch safety switch, which is located underneath your clutch pedal and completes the circuit when your pedal is depressed.

Ignition switch: troubleshooting Jinma and Farm Pro tractor partsIf there aren’t any issues with the clutch safety switch, move on to your ignition switch. The ignition switch has five key positions: off, on, heat (glow plugs), and two start positions. Begin with a visual inspection of the wiring off each one of the posts. If you can’t get your starter to do anything, it may be that your ignition switch isn’t diverting power down to the solenoid when you move the key into the start position.

You can use a multimeter to check the voltage at your solenoid post; the key will need to be in one of the start positions for this test. If you are getting action from your gauges in the on position but are not able to get any power to your solenoid, it is likely that your ignition switch needs to be replaced. You can find the replacement ignition switch for your Jinma tractor here.

Battery & Alternator

Testing your tractor battery: Jinma and Farm Pro tractor partsMoving on from the key switch, the next thing you will want to check is your battery. It’s usually pretty easy to diagnose your battery, because you won’t be able to get power to anything on your tractor if it’s completely dead. A dead battery may be the result of something continually drawing power from it, and not a problem with the battery itself. I would recommend having somewhere like AC Delco or AutoZone test it for you free of charge if you can’t test it yourself. You can do the same for your alternator—if your battery checks out, you should check your alternator to make sure it is functioning properly and charging your battery.

On occasion your starting issue will stem directly from the starter itself; you can read more about diagnosing that particular problem in our article “How to Test the Starter and Solenoid.” But most of the time, the problem is as simple as a faulty ignition switch or clutch safety switch.
