5 Typical Raptor Zero Turn Mower Problems and How to Fix Them

If you run into one of the typical problems associated with the Raptor zero-turn mower, you shouldn’t let yourself stress too much. These are generally not severe issues as long as you don’t let them go after you notice the initial warning signs. 

Now, we will take a detailed look at what causes these problems and the best ways to fix and prevent them. 

 1. Drive Belt

A broken or loose drive belt is one of the most common problems you’ll run into with the Raptor zero-turn mower. This could be because of an issue with the mounting system or rubbish and dirt accumulation on the deck and driving pulleys. 

If one of these things causes the drive belt to become loose, the blade most likely will not turn the way it needs to, which prevents the mower from doing its job. 

Additionally, the drive belt can become worn over time, leading to loosening or breaking. 


If you’re aware of the things that generally cause issues with the drive belt on these mowers, you may be able to prevent them if you take the appropriate precautions. In addition, taking these precautions will help you avoid the need to replace the belt more often than you should. 

First, you should ensure that your deck is correctly secured to the mower. If it is not mounted correctly, the deck will shake while the mower is in use, putting additional strain on the belt. 

It’s also helpful to thoroughly clean underneath the deck after each time you use the mower. This will help prevent buildup on the belt, keeping it from turning correctly. Additionally, pay close attention to the drive pulleys while you’re doing this to ensure they’re able to perform as they should. 

Unfortunately, you could still have issues with your belt even if you do these things. If your drive belt does become loose, has visible signs of wear, or breaks, it will need to be replaced. 

 2. Engine Issue

Owners also have experienced issues with starting the engine. In some cases, the engine will not start at all. In others, however, the engine will start as it should but becomes weaker and eventually dies back out. 

This problem is generally caused by dirt/dust in the fuel filter, faulty spark plugs, or a problem with the fuel that is in the mower. You may also experience this engine issue if your mower’s fuel levels are low. However, several other things could create the problem, including the carburetor, fuel pump, and battery. 


If your Raptor zero-turn mower won’t start, the first thing you should check is the fuel. You’ll need to ensure that the fuel levels are not low and that there is no rubbish or water in the fuel. 

Next, make sure that the fuel filter is not dirty. When the filter is dirty, the mower will not get the airflow that’s necessary for it to run efficiently. In most cases, you can clean the filter to fix the issue, but if it’s too bad, you may need to replace it with a new one. 

You should also ensure that the spark plug is connected correctly with no dirt or debris. Replacing it is the only option if it is connected well and still not working. 

If these things do not fix the problem, you can try the following things:

  • Clean the carburetor
  • Clean the battery terminals
  • Test the battery
  • Replace the fuel pump 
  • Replace the starter

If all options have been exhausted and your mower still fails to start, consider contacting a professional to have them find and fix the issue. 

 3. Cutting Height Disparity

Some owners have noticed unattractive patches or strips of grass that are not the same height as the rest after mowing with their Raptors. 

The most common causes of this issue include dull blades, a twisted blade spindle, or cutting on uneven ground. However, it can also occur if the anti-scalp settings are not set to the appropriate setting or if one or more tires are flat on the mower.  

In more severe cases, the problem is caused by bent blades or a twisted blade spindle. 


If your mower is cutting unevenly, you should first make sure the deck is level. You can find instructions on how to do this for your specific model in your manual if needed. 

It could also simply be that the anti-scalp dial is not set to the appropriate height or that one of the tires needs air. If the height is set correctly, check the psi in each of the tires. Each tire should have between 8 and 12 psi. 

Next, you should check the blades. You’ll want to ensure that there are no bent or dull blades. If the blades are bent, the best option is to replace them. If you do not see any bent, consider sharpening or replacing the blades. 

Unfortunately, one of the common causes of uneven cutting may require hiring a professional to fix it. If a bent blade spindle causes your issue, it’s not a simple fix, and it’s best if you do not attempt the repair yourself. 

4. Smoke Emissions

Smoke emissions are another typical issue associated with the Raptor zero-turn mower. The problem usually results from a clogged air filter or low engine oil. However, it can sometimes be caused by more severe issues like lousy piston rings, engine gaskets, or valve trains. 

When the air filter is clogged, it prevents the engine from receiving the airflow needed to run efficiently. When this happens, you’ll notice excessive oil usage and smoke emissions. Additionally, when the engine oil is low, smoke emissions may result from the friction created within the engine. 


If you see smoke emissions, you should first check your oil. You’ll want to ensure the engine has the required amount of oil and that the oil isn’t old. If it has been some time since the last oil change, consider changing it. 

Next, check your air filter and make sure that it’s not clogged. If you notice excessive buildup on the filter, you’ll need to remove it and clean it. If the filter is worn down or too dirty to come clean, you’ll need to replace the air filter. 

Running your mower with low oil, bad oil, or a clogged air filter can lead to further, more severe damage to your engine. In some cases, it could result in the engine needing to be replaced. So, to prevent this issue and severe engine damage, it’s best to check your oil and air filter regularly. 

If the smoke emissions are not caused by the oil or air filter, you most likely have one of the more severe issues. These issues will require hiring a professional to fix them. 

 5. Breakdowns While Mowing

A clogged air filter may also cause the mower to break down while you’re mowing. Several owners have reported experiences where their mowers died out while they were cutting but seemed to be running fine moments before. 

This can also be caused by old fuel that has been in the tank for too long. Old fuel can collect debris or corrode the fuel pump, which will prevent the proper fuel flow. If the fuel flow is unexpectedly interrupted, it will cause the engine to die out, sometimes with no warning. 

Raptor Zero Mower Air Filter


If your mower breaks down while you’re mowing, the first thing you’ll want to check is the fuel. You should ensure that there is plenty of fuel and that it doesn’t appear old/dirty. 

Also, consider how long the gas has been in the tank. If it has been sitting in the tank for more than 30 days, you should empty it, clean it, and add fresh fuel. 

If the issue isn’t the fuel, check the air filter. You should clean it thoroughly if there is a lot of dirt or other buildup. In some cases, you may need to replace the filter. 

To prevent your mower from breaking down while you’re mowing because of these things, regularly clean the air filter to keep it from getting clogged. 

You should also drain the fuel, clean the gas tank, and add new fuel once a month to prevent issues with the fuel that could block essential parts of the fuel system and cause the mower’s engine to die out while mowing.

  • Oil
  • Oil filter
  • Fuel filter
