1. Steering Problem

John Deere SST18s are known to have steering problems. When you turn the steering wheel, something is supposed to activate and turn the wheels. 

However, many John Deere SST18 owners have reported that their mower steering doesn’t turn at all. 

Not left, not right, neither going forward or backward. If you’re having this problem with your mower, it’s most likely because something is wrong with the vacuum actuators. 

Or maybe the vacuum line and elbow at the engine are leaking. Because sometimes due to their leakage your mower will have steering problems. 

However, the best way to fix this problem is to take your mower to a John Deere dealer and have them take a look at it. John Deere dealers are experts on their products and they should be able to fix the problem quickly and easily.

2. Not Moving Forward or Backward

John Deere SST18 owners are having issues with their mowers not moving forward or backward. There are a few things you can do to resolve the problem. 

Check the drive release handles and make sure they are in the operating position. You can find out where your mower’s drive release handle is located by consulting the owner’s manual. 

Another thing to check is the drive belt; it may be worn out, loose, or broken, which is preventing the mower from moving. 

Also, check the tensioner pulleys; sometimes they break, which can also cause the mower to get stuck. 

And last thing, low or hot hydraulic fluid can also be a problem, so make sure to check the fluid levels and ensure that the fluid is not too hot. problems you are having.

3. Not Starting

John Deere SST18s are very versatile lawn tractors that can do a lot of different tasks around the yard. One of the most common problems that John Deere SST18 owners face is that their tractors won’t start. 

There are a few different things that can cause this problem. So, first, check the battery. If the battery is dead, your mower will not start. 

Second, check the fuel level because this mower requires a lot of fuel, and if they don’t have enough, it won’t start. And at last check the air filter. 

These mowers have a very sensitive air filter, and if it is dirty, it can prevent the engine from starting. 

Tip: If you are having trouble starting your John Deere SST18, make sure to check all of these things before taking it to a John Deere dealership for repairs.

4. Charging Light Problem

Another common issue with John Deere SST18s is that the battery charge light starts to come on intermittently. This can be frustrating for owners, as it’s not always clear why the light is coming on.

Fortunately, there are a few steps you can take to troubleshoot the issue. First, check the voltage of the battery. If it’s in spec, then the issue is likely not with the battery itself. 

Next, run the machine with a voltmeter attached and see if there’s any difference in the readings when the light is on or off. If not, then the problem is likely with the John Deere SST18’s charging system. 

Finally, try partially discharging the battery and see if that makes a difference. If so, then it’s probably time to replace the battery. 

Replacing the battery is a relatively simple process and should solve the issue for good.

5. Tractor Vibrates Too Much

John Deere SST18 Lawn Tractor owners have reported that their tractors vibrate too much and cause them to feel uncomfortable. 

John Deere has released a service bulletin that recommends replacing the front and rear tires on the tractor when this problem arises. 

John Deere also recommends that the front axle be checked for alignment and that the caster wheels be properly inflated before operating the tractor. 

6. Tractor Too Loud

Another common issue is that the tractor is too loud when it’s running. This makes it difficult to hear other yard tasks that are going on at the same time, which can be frustrating. 

If your John Deere is too loud, it’s likely that the muffler or air filter needs to be replaced. Both of these parts are designed to help reduce noise, so replacing them should help to make your tractor run more quietly. 

In addition, John Deere recommends that you regularly check both the muffler and air filter to ensure that they’re in good condition and not contributing to the noise problem. 

7. Not Cutting Grass Evenly

John Deere SST18 tractor owners are complaining that their mower is not cutting grass evenly. However, it’s not the manufacturer’s fault, it is due to users’ mistakes. 

John Deere SST18s is equipped with two cutting blades. These cutting blades are made of high-carbon steel for strength and durability. However, over time, the cutting blades will become dull and will need to be sharpened or replaced. 

In addition, the positioning of the cutting blades is critical to ensuring an even cut. If the blades are not properly positioned, the John Deere SST18 will produce an uneven cut. 

To solve this problem, you should sharpen or replace the cutting blades, and ensure that the blade is in a proper position.
