1. Engine Problem

The Stiga mower engine problem is something that a lot of people are struggling with. 

Many people have complained that their engine conks out under load or while moving forward and backward. 

This problem happens when your mower spark plugs are dirty, loose, or not properly connected. 

So, you should first clean the spark plugs, then unplug and firmly plug them.

The bad fuel in your mower or dirty air filter can also be responsible for conking of your Stiga mower engine. 

So, you should also check your fuel and clean the air filters.

2. Starting Problem

The Stiga mower starting problem is another common issue that many owners are facing. There are several things that you can do to fix this problem. 

First, you should check the gas tank because it is the most common cause of the problem. 

If the gas tank is empty, then fill it with gas to start your mower. But if you have filled the gas tank but still the mower won’t start, then you should check for leaks. Maybe the tank is leaking. 

However, if your Stiga mower is battery-operated, you should check its battery. If the battery is damaged, you should replace it. 

You should also check the spark plugs of your mower. Because sometimes they are dirty due to which your mower won’t start. 

In this case, you should clean the spark plugs. However, if the plugs are not working, then you should buy new ones.

3. Smoking a Lot

Many people are complaining that their Stiga mower is smoking a lot. This will usually happen if the mower chamber is too full with oil. So, you should check if it is full, then lower the oil level.  

Also, if oil is leaking from the chamber mower will smoke, mostly oil will leak if the cap is not tight enough. So, when your Stiga mower is cool, you should check the chamber area for leaks. 

And if any part is loose or broken, you should replace it.

However, if your mower’s smoke is a white and light color, it means it has some serious issues. Therefore you need to consult a professional who can fix your mower.

4. Hydraulic Oil Leakage

Hydraulic oil leakage is a common problem in Stiga mowers. Mostly hydraulic oil leaks when it gets hot. 

This happens when the oil level is too high, and there isn’t enough space in the tank for the oil to expand.

To fix this problem, remove some oil to lower the oil level back to where it was before. Also, make sure all bolts are tight; if some are loose, tighten them.

If you continue to have problems with hydraulic oil leakage, you may need to replace the breather valve or add an expansion tank to your mower.

5. Moving Slow

This is another common problem that Stiga mower owners face. In this problem mower doesn’t move fast as compared to when it was new. 

Clogging is a major reason for this problem. This can be in many parts of your mower, including the fuel line, gas cap, needle, and air filter. 

To fix this problem, you should clean your mower’s outer filter and inner filter with compressed air. 

However, you should replace the gas caps, needle, and seat instead of cleaning them.

6. Steering Problem

Many Stiga mower owners have reported steering problems. The most common symptom is that the mower will veer to one side or the other, making it difficult to keep it on a straight path. 

In some cases, the steering wheel may even become locked in place. While this can be frustrating, there are a few things that you can do to try to fix the problem. 

First, check the air pressure in the tires. If the air pressure is low in tires then inflate them to the recommended level. The next thing you should do is adjust the caster wheels.

If they are not properly aligned, it can cause the mower to veer. 

In the end you should check the alignment of the front wheels. If they are out of alignment, it can also cause steering problems. 

7. Uneven Cutting

Many Stiga mower owners have complained about an uneven cutting problem. One possibility of this problem is that the blades are dull and need to be replaced. 

Another is that the lawn has not been adequately cleaned, and there are obstructions preventing the blades from cutting evenly. 

If the blades are dull, they will need to be sharpen. You can either sharpen them yourself or take them to a professional. However if sharp blades doesn’t work then you will need to replace the blades.

Once the blades are replaced, they should be able to cut through any obstructions in the lawn and produce an even cut.

If the lawn is not clean, you should clean dirt and debris from it before mowing. Be sure to remove any sticks, stones, or other objects that could prevent the blades from cutting evenly.
