2. Chutes Getting Clogged

Due to the usage over the years, the chutes might get clogged. This might be due to dirt residue forming as well as due to grass sticking up. One of the main reasons is when mowing in the wet grass thus, they end up sticking to the chutes.  


To clean up the dirt residue, brushes seem to be very useful. The dry leaves and wet grass can also be removed by using an air blower. By thoroughly cleaning the chutes, it is likely to fix your problem. However, do keep in mind not to clean the chutes with a water hose as the water might end up in the engine.

3. Belt Popping Out of The Pulleys

This is a common problem that has been witnessed by various customers globally. The main reason for this problem is due to the cross braces. As the cross brace starts to dislocate or eventually breaks off, the belt might slide out. This might as well cause tears on the belt. Thus it would prevent the mower from functioning correctly.  


  • In order to deal with the belt popping out, the first solution would be to replace the cross braces of Raptor SD. Afterward, the belt can be pushed back in, and there will be no problem.
  • In case of a broken belt or tears in the belt, the belt has to be replaced.

4. Fan Blade Breakdown

As the belt comes off to become loose, the belt might hit the fan blades of the mower. This would cause friction damaging both the fan blade as well as the blade. In further instances, the belt might get wired up to the fan blade and thus break the fan blade.  


  • To avoid the breakdown of fan blades, regular check-ups of the belt, cross brace, and fan blades are highly recommended. As all these are the aftereffects of a series of incidences.
  • In case the fan blade has already broken, the blades have to be replaced in order to properly use Raptor SD.

5. Leaking Hydrostat

The hydrostat in the Raptor SD might sometimes not be mounted properly. This causes the hydrostat to leak. There are even instances where the bolts securing the hydrostat come loose, thus causing the hydrostat to leak. However, this is not a problem of Raptor SD but of the hydrostat itself.


  • Leaking hydrostat can get fixed easily. In case of the bolts come loose, it can be easily tightened up at home.
  • If tightening up the bolts does not appear helpful, you can purchase the hydrostat kit that is available. This kit price would range from a couple of hundred dollars.

6. Grass Cut Inequality

Upon the usage of Raptor SD over the years, users tend to complain due to uneven grass cuts. There is a range of probable reasons for this problem, both based on Raptor SD and the land.  

Common problems:

  • Dull blades

  • In case of uneven land surfaces, adjusting the deck per the Raptor SD instruction manual will help.

  • Flat tires are one of the main reasons for grass-cut inequality. According to the Raptor SD manual, having the tires at a psi of 8-12 would help continue mowing smoothly.

7. Raptor SD is Not Starting; Just Clicks

This is yet again another hugely observed problem occurring in mowers that have already been used for quite a long time. One of the reasons might be due to the solenoid being burned or unable to provide power to the engine. Another probable cause is due to the safety switches being loose.


  • In case of problems regarding solenoid jump-starting, the Raptor SD is a short-term solution.
  • In the long run, replacing the solenoid with a new one would fix the problem.
  • If the safety switches of the handle come loose, tightening the switches might fix the problem at hand. In order to tighten the switch, you have to lift the seat and reach over below the safety switch and tighten up the bolts.
  • Be advised, the safety switch is made of plastic; applying too much pressure might break it.

8. Engine Stall

While using the Raptor SD, some customers complained that the engine started up and suddenly stopped in the middle of mowing. This problem is caused due to various reasons such as burned spark plugs, old and filthy gasoline, and low fuel.


  • First, do, check on the fuel that is available in the tank.
  • In case the spark plugs are filled with dirt residue or are burnt, replacing them would start the engine.
  • In the case of old gasoline, replacing it and monitoring it very often would be recommended.
  • The fuel filter should also be replaced every 200 hours of usage as dirt residue tends to form.
  • Throttling the engine while operating in cold weather helps to keep the mower from becoming stalled.

This is another problem that seems to be very common and makes the users worried a lot. As the grass sticks to the chutes, it makes the engine heat, thus overheating it.
