7 Common John Deere x590 Problems and the Solutions
1. Engine overheating issues
Engine overheating problems often stem from dirty or poorly adjusted carburettors or clogged cooling fins. Inspecting, cleaning and overhauling components mostly fixes the problem.
Another cause for overheating could be the amount and quality of oil. You don’t want your oil level to be too high or too low, it could raise the temperatures in your engine.
Besides checking the oil level, it’s also advisable to use the right grade of oil and ensure that it has a viscosity that’s good for the engine.
The wrong engine oil will damage your X590’s engine and, or components like clogged cooling fins because it will not lubricate the components properly.
When this happens, the components rub against each other. This friction will then cause engine components to wear and tear. An engine can also overheat due to excessive engine load (overworking).
For example, if you mow long, hard and wet vegetation for a long time, you should expect your John Deere X590 engine to heat up. This is also common with other X5 series, such as John Deere X570 and John Deere x758.
It’s a good idea to limit your mowing to your X590’s engine’s capacity. Regular maintenance will help you avoid this problem.
2. Fuel system issues
There are various reasons as to why X590s develop fuel system issues. From clogged fuel lines due to stale fuel to stale fuel in the tank, and faulty fuel injectors (which causes the engine to misfire because of an unbalanced flow of fuel and air to the engine).
A machine or system that’s not working properly can dent your pocket. You will end up spending more money on fuel and risk a fuel leak which could lead to an engine detonation among other things.
Troubleshooting this problem is easy. Turn your X590 key to run and then listen carefully. If you hear a humming sound in the gas tank, you have a fuel system issue and that’s what you need to target.
Another indicator that will point to this problem, particularly a failing fuel pump, is soft explosive sounds when the engine runs consistently at high speed.
It’s not consistent—it just happens and then the John Deere X590 goes back to normal. The fuel pump could be faulty – most likely clogged.
The solution is simple—mostly it’s something you can do on your own if you can comfortably handle such a machine.
Empty the stale fuel, refill the tank with clean fuel and, or replace the broken fuel injectors. However, if the issue is a clogged filter, you need to replace it (not clean the filter and reinstall it).
Reusing filters causes more problems. Fuel filters become worse after “cleaning”. They lodge dirt or debris further in and any wrong air or fluid pressure damages them.
This is one of the common problems and according to the manufacturer, you need to “replace after an initial 100 hours, then every 250 hours or annually.
If Plus-50™ II oil and John Deere™ filter is used, the interval may be extended to 500 hours.”
Head to a reliable John Deere mechanic if you’re not proficient in taking on such challenges. You don’t want to cause more damage trying to fix this problem.
3. Wrong fuel grade and faulty injectors
Wrong fuel grade or old fuel will limit power supply while faulty fuel injectors will push less fuel.
The best fix for this is to drain the old fuel in the fuel tank with all the accumulated dirt and debris, then add fuel that is clean and of the correct grade.
While at it, replace faulty fuel injectors because stale fuel becomes gummy after a while, clogging the fuel line.
Some pointers that your fuel injectors are blocked includes engine sputtering whenever you accelerate, excess fuel consumption, rough idling, bad start or worse—a dead engine.
It’s also prudent to check for a defective spark plug and a clogged fuel filter. Clean the spark plug, adjust the gap, or, if necessary… get a replacement from a reliable dealer and replace the fuel filter if it’s clogged.
4. Excessive vibration
We have to give it to John Deere for trying their best to make the X590 model every gardener’s dream—comfortable, easy to navigate through any terrain, and with an impressive ability to lift or carry heavy loads.
However, John Deere X590s are not spared excessive vibration. From loose blades or broken blades, dirt or debris in the mower deck, or a loose or worn belt, mower users have shared their struggle with this and the easy fixes that solved the problem.
As you can already tell, good and regular maintenance can keep this issue at bay. And, you don’t need to be an expert to repair some parts of this mower.
Fixes include cleaning the drive pulley (or replacing it with a new pulley) and the belt or the dirty mower, tightening loose blades or replacing the broken ones and replacing a loose drive belt.
5. Rough running engine
X590 is a sturdy, multi-terrain vehicle but a clogged and damaged air filter will prevent proper airflow to the engine, causing noise, excessive vibration, and underperformance.
A clogged carburetor will have the same effect, and so will clogged-up cooling fins. A clean carburetor will help keep your engine working, save on fuel, prevent corrosion, and help you avoid expensive parts replacements.
Another culprit that you might discover when troubleshooting for rough running is a faulty spark plug or a dirty spark plug—covered in fuel, oil or carbon deposits.
You might also discover the cause of the problem to be poor electrical connections. A sticking throttle cable could cause this issue and the fix is replacing the throttle cable.
Solutions include cleaning the air filter or replacing it if it’s damaged, cleaning up the carburetor or replacing it if broken, and removing the dirt and debris that has accumulated in the fins.
Replacing a faulty spark plug or cleaning it if it’s just dirty will mostly fix the problem.
After cleaning the spark plug, do proper wiring—ensure all the electrical components of the mower are correctly and firmly connected.
6. Mower deck issues
Show me an X590 mower with dull mowing blades or worn-out ones, and I’ll show you one that cuts grass unevenly, leaving patches of uncut grass.
Mowing problems also arise from uneven tire pressure and uneven mower deck, both of which affect the grass-cutting height.
Luckily, this is one of the common problems with mowers but it has easy quick fixes, especially if you’re comfortable with the equipment.
First thing you want to do is ensure the mower blades are always sharp by sharpening them regularly. If the blades are worn out, install new ones.
Second, ensure the tire pressure is even for all the tires—for good balance and the right cutting height.
To balance blades properly, check this on a solid, flat surface. Also, ensure all the tires are on the same level.
Third, do even up the level of your mower deck for a perfect cutting height. Last, adjust your blade spinning speed to avoid unevenly cut grass.
7. Engine power loss
This is not a John Deere problem. It’s normal for mowers to lose engine power over time just the same way equipment have wear and tear. As they get old, the seals harden and become brittle.
The piston rings and the valvetrain components also get old, resulting in a significant drop in horsepower and compression.
If your X590 is not old, there’s a cause for concern but it’s fine if it’s still under warranty. You can show up to the dealer with your warranty information and request them to install a replacement if this problem is not fixable.
There are many reasons as to why this could be happening. A problem with fuel, air, carburetor, compression or the spark plug can cause engine power loss.
A dirty or a clogged air filter will result in restricted air flow to the engine, forcing it to run on a fuel-rich mixture.
Since this mixture doesn’t burn completely, you’ll end up wasting fuel, the soot will clog up the exhaust, and you’ll have less engine power output.
A partly blocked fuel injector will also push less fuel while a clogged carburetor will cause the engine to get less fuel, resulting in a decline in your X590’s horsepower.
Other causes that you might discover during troubleshooting include a faulty fuel pump. It will cut off the power.
Excess engine oil is a problem because the oil can soak the spark plugs resulting in low power output.
The solution to these problems includes cleaning the carburetor bolted at the top, ensuring the proper level of engine oil, cleaning the air filter if it’s clogged, and install a fuel pump or a spark plug if they’re faulty.
If you’re comfortable and experienced in handling John Deere motor parts and equipment and dislike making trips to John Deere dealers or experts, you can do it yourself.
