7 Solutions For John Deere Tractor Won’t Start
We have seen the common problems that can cause your John Deere tractor not to start. Now, down below we will look into all the probable solutions to all the problems that can cause your John Deere tractor not to start.
1. Damaged Batter: Clean, Recharge, or Replace the Battery
Your tractor could not start due to disruption by a dead or damaged battery. Make sure to look for any obvious rust on the battery terminals.
A multimeter may be used to test the tractor’s battery, and the readings should be somehow closer to your battery voltage which is around 12.7 V
Start by cleaning the terminals with some baking soda and water and try to restart your engine, if it still doesn’t work then try to recharge your batteries. In case it still doesn’t work then you will need to replace the battery.
A replacement John Deere tractor battery can cost you anywhere from $50-$100. The best battery for the John Deere tractor is the Weize 12V 35AH Battery.
2. Faulty Starter Solenoid: Clean or Replace the Solenoid
A starting solenoid is a type of low-amp switch system that links the starter and battery electrically. One of the biggest causes of the John Deere tractor not starting is a bad starter solenoid.
If you see that all other parts are working fine and still your tractor is not starting, then the solenoid is at fault.
Try to clean the solenoid first as sometimes dirt and debris clog this. If the solenoid still doesn’t work then you will have to replace it.
The replacement process is very easy and you can do it by yourself by following the manual that came with your tractor.
Typically replacement John Deere solenoids come at a price around $12-$32 depending on models and brands.
3. Clogged Fuel Filter: Replace the filter
When using soiled or outdated gasoline, a fuel filter may clog. To stop dirt and other impurities from reaching the fuel tank, the filter is made to screen the gasoline.
When it gets blocked, it might hinder the appropriate fuel flow and make it impossible for your engine to start normally.
Unfortunately, you cannot clean or repair a clogged-up fuel filter and you will need to replace it with a new one.
If you have a repair company change your fuel filter, it should cost about $50 and $175. But if you choose to do it yourself, it will only cost you $25 to $30.
4. Problematic Spark plugs: Replace with new ones
Spark plugs are one of the most complicated essentials for your tractor and they seem to get damaged once every 2/3 years. By looking at your spark plug, you can determine if it is damaged.
Change your spark plugs if there are any sediments or Leaks, or if it simply doesn’t seem right.
Different models of John Deere tractors use different models of spark plugs, but the most common one is the Champion RC12YC spark plug.
Replacing a spark plug can cost you around $5-$20 depending on the type of plug it is using. However, if you hire a mechanic the cost will be much more.
5. No gas in the fuel tank: Refill your tank
Sometimes, your tractor won’t start due to one simple and silly reason and that is your fuel tank is out of gas. While looking for more complicated reasons we often forget to check our fuel tank
The fix is pretty simple, all you need to do is refill the whole fuel tank with new fuel. After you have filled up the tank try restarting the engine and your tractor should be starting and running fine.
If it still doesn’t run then you will need to increase the engine pressure. The tractor’s engine’s built-in priming pump can be used. Every ten minutes, continue pumping to build pressure and eliminate air from the fuel tank.
6. Problematic fuel cap: Clean or Replace
In addition to letting dirt and filth in, a broken fuel cap may also enable gasoline vapors to leave the gas tank. These gasoline vapors can cause the emissions system to malfunction, which would prevent the tractor from starting.
The looseness or inability to fully tighten the gas cap is the most typical sign of a broken cap. The only solution is to buy a new fuel cap and replace the old damaged one.
Fuel caps also vary from model to model but New Stens Fuel Cap 125-183 is compatible with most latest models of John Deere tractors. These caps are available for around $18-$25.
7. Carburetor issues: Clean or Repair
Clogged-up carburetors are another common reason that can cause John Deere tractors not to start. Carburetors’ principal job is to combine air and fuel for a high-combustion mixture. As a result, it may become filthy, blocking up parts and hindering effective operation. By doing this, the gas flow required to start the tractor will be stopped.
The cleaning process of the carburetor is quite easy and you can do it by yourself. Open all the parts inside it and clean it using cleaner, all the problems should be solved. However, if the condition seems way beyond cleaning; a replacement is needed.
You can either rebuild a carburetor or replace it completely. Rebuilding will cost between $300-$500. But a complete replacement can cost much more around $1000-$2000.
