As tractor fuel systems become more complex with technology improvements and emissions regulations, it is becoming more important than ever to be attentive of your fuel injection system. Modern tractor engines sold in the United States and Europe must comply with Final Tier IV regulations, which increases the need to monitor your fuel systems. Preventative care helps save you time and money. A damaged fuel injector system can be several thousand dollars when you account for all-in repair costs.
Water inside a fuel system can wreck havoc. Newer fuel systems are more sensitive to water than their predecessors.
When winter approaches it is important to add fuel stabilizer to fuel tank. Stabilizer prevents the diesel fuel from gelling up (this can occur when temperature drops below 10 degrees Fahrenheit / minus 12 degrees Celsius). There are many brands and offerings - make sure you use any specified fluids that your dealer and manufacturer recommend. Remember that using proper fluids is essential to maintaining an new tractor warranty in good standing.
There are a few steps to stabilize your fuel:
Fuel stabilizer also adds a lubricant which keeps your fuel injector system healthy. Low sulfur fuels required by emissions regulations have a lower amount of natural lubricants - as a result, your fuel system is more sensitive. Fuel stabilizer helps prevent premature wear on the system injection pump system.
You should check your fuel sediment bowl each time you startup your tractor. Look to see if the floater is elevated (indicates water), or there is sediment buildup (can happen over time). A floating ring in the fuel bowl indicates the presence of water. If the water level rises enough it can make its way into the engine and cause a lot of damage to both your tractor and your pocketbook.
If there is a moderate amount of water in your fuel bowl (it has not yet spilled over into the engine) then you can address the issue on your own with a few easy steps:
Properly caring for your tractor's fuel system is easy if you remember to prepare it for the seasons and check it before starting the engine. Similar to the age old saying "A stitch in time saves nine," following these steps will save you time and money.
