Top 4 John Deere X370 Problems (Troubleshooting Tips)

John Deere X370 is a popular lawn tractor, even though it was only released by the John Deere brand in 2016 and is still in production. From 2016 until 2020, the tractor used a Kawasaki FS600V engine in what can be termed the first phase.

However, from 2021 till date, John Deere made some changes to the tractor, called the second phase. 

If you have owned a John Deere X370 before, you should know that poor engine performance, battery, and tractor rattling are the machine’s most common and significant faults. There are many reasons why this part fails and many other ways to correct it.     

This article will state some of the common John Deere X370 problems you are most likely to face, their causes, and solutions.   

John Deere X370 Problems

Some significant problems you would encounter with your John Deere X370 problems include; 

1. Engine problems 

Poor engine performance is mainly caused by too much-clogged dirt in the fuel or an old fuel system. Sometimes, the primary reason your john Deere engine would develop problems is the wrong fuel you used; all you have to do is replace fuel with fresh, stabilized fuel. 

If this is the case with your John Deere X370, you should check for any of these solutions. 

Some standard fuel solutions include;

• Changing your fuel supplier if you notice too many issues with the present supplier
• Ensuring that your fuel is not blended with alcohol. Fuel blending causes gums and vanishes deposits in your fuel, especially if this fuel has been in stock for too long
• Obtain fuel from another supplier before suspecting machine problems
• Changing the entire fuel and replacing it with a fresh batch

Some other common sub-reasons why your engine would not start include:

The engine misses the underload

This problem is mainly caused by faulty spark plugs, clogged or dirty fuel filters, and stale fuel. You can feed all these problems all by yourself without having to pay for services. 

All you have to do is replace all faulty spark plugs and also ensure you clean up the fuel filters for debris and dirt. If you notice that the fuel tank’s fuel is stale or dirty, then ensure that you empty the fuel tank and replace the fuel with a new one. 

Engine vapor locks 

There are a few reasons why this happens with the engine of your john Deere x370. Some of the reasons include a plugged fuel tank, dirt in your fuel filter, and a plugged-in fuel filter. The solution to this problem is very easy. 

All you have to do is check on your fuel filter and vent and ensure it is not clogged. If you notice any dirt or debris around this area, do well to get rid of it and if there is a need, get yourself a new fuel filter. 

Engine overheats 

An overheating engine is a very abnormal situation that you must treat urgently to prevent more significant issues. Some common reasons this happens are plugged-in cooling fins, engine oil level being too low or too high, operating your engine too slowly, and a plugged engine intake screen. 

To fix these issues, ensure that your cooling fins are free of dirt or debris by cleaning them. Also, if you notice that your engine oil level is too low or too high, ensure you get it to an adequate amount. Keep your engine at a steady speed, as that can also build up the heat in the engine. 

The engine will not idle 

This issue results from your spark plug needing to be more gaped or adequately operating your device with a faulty spark plug. You can fix this issue by replacing your spark plug when you find out that they have gone bad or properly spicing your spark plug. 

Engine knocks 

Engine knocking is a common issue with most models of John Deere mowers. Some common reasons why this happens are stale fuel or using fuel with a low octane rating. Operating your machine at a low engine speed and the oil level can result in a knocking sound from your device. 

You can fix this issue by getting fuel of the correct grade and filling it into your mower. Also, do not overload your engine; only operate your machine when the engine oil level is low. Once you ensure all these, you should be able to fix the knocking issue for a long time. 

Engine stops or misses when operating on hillsides 

This usually happens when your fuel tank needs more fuel, or the operator raises the seat off. Your mower would need more fuel to power the engine to the hillsides. 

You can fix this issue by ensuring that your fuel tank is always filled before any operation, not just when you operate close to hillsides. 

Excessive fuel consumption 

Whenever you notice that your mower keeps consuming more fuel than usual, your choke needs to be fully open. This problem can be frustrating, but it is bound to stop once you’ve handled your choke correctly. 

Mower releasing Black exhausts smoke 

Your mower is not supposed to be giving off black exhaust smoke, but when this happens, it results from the air filter being dirty or soaked with oil. You should clean your air filter after every operation to prevent issues like this.
