The durability of New Holland tractors is well-known all around the world. You cannot expect any major problems when these tractors are under your use. However, they are a piece of machinery, and machinery can bring you inconvenience sometimes.
Most of the users have reported that their New Holland tractor turns over but doesn’t start. There are certain things to check if you need a solution for that problem.
Fixing New Holland Tractor Turns Over But Won’t Start
- Check The Fuel Filter
The biggest factor that can contribute to not starting the New Holland tractor is the fuel filter. Take it off and inspect it well. A dirty fuel filter gets clogged and prevents the fuel from getting to the engine.
Make sure you have properly cleaned the fuel filter. Now proceed to start your tractor again. If, even then, the tractor won’t start, replace the filter.
- Check The Air In The Fuel
There are three basic factors that are necessary for the efficient functioning of the New Holland tractor. They include fuel, air, and heat. Sometimes air gets entrapped in the fuel lines and prevents the proper pressurizing of the engine. In this way, fuel fails to reach the engine.
The function of the fuel lines can be restored as soon as you bleed the air from a diesel fuel system.
- Test Your Battery
Sometimes a dead battery is a primary reason behind not starting the tractor. Whenever you try to start the tractor, there is just a small click that you can hear. You might not even hear anything. That’s the sign of a dead battery.
Cleaning of the posts is required to restore the function of the battery. The first attachment that needs to be removed is the Negative one. Afterward, remove the positive attachment as well. Now, get a hold of a mixture of baking soda and water. Use it for cleaning the posts.
Before you reattach the cables, make sure the terminals are completely dried. Make sure the order is correct. The positive needs to be attached first, followed by the negative.
If this doesn’t start your tractor, it means your battery is dead. Other signs of a dead battery include bloating and swelling of the battery case. In that scenario, it is best to take the suggestion of a mechanic. The latter can check the battery and run a test on its life.
- Fill Your Fuel Tank
Sometimes people ignore the most obvious and clear reason. There is a high chance that you just ran out of fuel, and that’s stopping your New Holland tractor from taking a start.
You need to check the fuel level inside the fuel tank. If there is insufficient fuel, fill the tank. It may not solve the issue because the common knowledge says that the tank cannot be refilled and started again as soon as the engine runs out of fuel.
You need to prime and pressurize the engine manually. Take a built-in fuel primer pump to get rid of the air from the fuel lines.
This process takes place in a number of steps. The first step is to find where the fuel primer pump is. Locate the bleed screw as well. Next, you let the air in the fuel lines go somewhere by loosening the bleed screw.
Air in the lines cannot be dispelled unless you keep pump inhibitors in the fuel primer for 5-10 minutes. Now, make sure that the bleed screw is tight enough to proceed with the replacement of the fuel pump. Try starting the engine again. You can repeat the process if there is no progress observed.
- Cool The Engine
Overheating can also prevent the starting of the New Holland tractor. The lack of coolant is a potential cause behind the overheating. First of all, wait for the engine to cool down completely. Now check the level of coolant by removing the radiator cap. If the level is low, refill the radiator with the coolant.
The engine cannot stay cool if there isn’t enough air. Dust and dirt can make the radiator fins dirty and make them unable to produce sufficient air. You cannot start cleaning the fins all of a sudden.
First, wait for the engine to cool down. Next, you can blow the dust off the fins by using an air compressor. You have to be careful about the metal pieces as they cannot be bent.
The malfunctioning of the engine thermometer can affect its ability to read the temperature. In case it reads a false temperature, it can shut down the engine of the tractor prematurely. You can test the thermometer by putting it in a hot boiling bucket.
The deterioration of the hoses that run from the radiator is quite common. Sometimes the holes are big enough to be seen with the naked eye. The best thing to do in such a case is to seek the help of a professional.
- Check Your Fuel For Contamination
The contamination of the fuel is common, and it can keep your engine from starting. To check for the gasoline traces in the fuel, you can simply smell the fuel. If you smell any trace of gasoline, you need to flush the fuel. Now fill the tank with the new fuel.
You also need to run an inspection on the stored diesel fuel. Microbes can cause contamination.
- Check The Outdoor Temperature
It gets very hard to start a New Holland tractor in the cold. The diesel engines are most likely to be affected by the lower temperatures. It’s not just the parts of the equipment that are prone to damage but the fuel and oil as well.
As soon as the temperature is lower, it causes the thickening of the engine oil. In this way, there is a drag on the engine. Sometimes the drag is too much that it affects the ability of the engine to create enough compression. As a result, the fuel cannot be ignited, and the vehicle cannot start.
If you want to get things going on, check the dipstick. All you need to do is change the oil with a winterized oil.
The effect of cold on the battery is also harmful. It brings a significant decrease in the battery output. The engine cannot get powered by a limited number of amps.

I have a 29D and it has worked perfectly for many years but the other day I checked the oil level and it was a little low so I had the hood up and inadvertently I poured some oil in the fuel tank. I realized this immediately so I drained the diesel fuel tank and replaced the diesel fuel. I also drained the fuel ling where the fuel filter is located and replaced a new filter. Still the tractor would not start even though it sputtered a little. Next I bled the fuel at the closest and easiest bleeder valve and left the valve opened and tried to start it with the valve open and dripping fluid. It sputtered quite a bit when attempting to start.(electrical seems fine). It just would not catch and continue to run on it’s own. Exhaust was darker as it it was burning the oil. I left the bleeder valve open and brought the hose completely down hoping that this would drain any contaminated fuel. I will check it today. Thanks for any help.
