DR Brush Mower Problems In Brief With Solution:

Now that you have gotten an idea about what problems you may face while using DR Brush Mower, let us discuss in broad what causes them and how to fix them.

1. Mower Emits Smoke

The sudden smoke you see vaporing from the mower could occur if the amount of fuel in the mower is either too much or less than the required amount. If the carburetor is not able to mix the air and oil together, the engine won’t work properly. This would cause the smoke to form and make it difficult for you to mow.     

Solution

This could be fixed by setting the choke to be used automatically if you are a new user. Moreover replacing the air filter could solve it and the prices are not that high either.

  •  Constantly maintaining the air filter by cleaning the filter regularly.
  • Solving the problem of oil to fuel level by looking at the instruction guide and measuring and pouring it at the exact amount required for that model.

2. Stalling Engine

If the DR Brush Mower keeps stalling regularly, the reason why it keeps happening could be due to the oil being too old to use, or the carburetor might be covered up in dirt or blocked.

Also, it could depend on the level of grass you are cutting. Furthermore, this could vary if the person is cutting at a higher level of speed.

Solution

You can solve the stalling engine problem by changing the carburetor or changing the spark plug. You can also reduce the pace of cutting to resolve the issue.

3. Blades Not Working Perfectly

Sometimes, the direction or the way in which the blades are rolling might not be suitable or satisfactory to cut. This could occur if the bolts are loose. Moreover, the level of the deck not heightened accordingly could cause this problem.

Solution

Nutting the bolts tightly could prevent this from happening, or by changing the bolts if it is used out or diminished.

4. Power Of The Engine Being Insufficient

The majority of the users might face this as a blocked, and dirty air filter would cause the powers of the engine to be less powerful, and thus it would get slowed down.

Moreover, the spark plug, again, might be an issue along with the ignition coil. To add to it, the temperature could also cause this as well. If it is way too hot, then this could lower the performance of the engine, which could slow it down.

Solution

  •  The solution to this is similar to the previous ones. As if the amount of fuel that is in the DR Brush Mower is lower than the required amount, then this issue could be resolved just by adding a sufficient amount.
  •  Also, if the spark plug is rigged and old. Then the matter could easily be solved by purchasing a new plug.
  •  Furthermore, if the machine is too hot, then let it rest for a while to cool off, which might also solve the issue.

5. Difficulties Faced While Backward Motioning

If you keep facing difficulties while backward motioning, the issue might be that the pulley bearings of the DR Brush Mower might be clogged or blocked up, being filled with debris and wearing away.

Solution

If the bearings are blocked up, this can be removed by scrubbing the corrosion away. However, if it is still not fixed, then the belt could be an issue. So you could replace it which can be used for at least 3-5 years with proper prolongation of keeping it well serviced and fresh.

6. Engines Having Issues While Starting

If you keep smelling gas while starting the DR Brush Mower, this might be caused due to the tank being overfilled with oil. Also, it might be an issue again with the spark plug, as it does hold the most important while starting the engine.

Solution

  • You should always keep an adequate amount of fuel in the tank as if you have significantly less fuel, this could cause the engine to keep having problems while starting it.   
  • And if you have smelled gas while running the engine of the mower, a few times after using it, it might be due to a faulty spark plug. Which can easily be fixed by changing it.

7. Engine Suddenly Stops Working

If you start the mower and it keeps dying, this might be caused by a congested bowl which would be found in the carburetor that makes the procedure of the engine very obsolete.

Solution

If your engine has been up and running and being used for a long time, this could build up dirt and effluvium in the engine. As a result, the engine might keep getting stopped. So this can be resolved by just simply replacing the engine or removing anything that is clogging up the engine.

8. Chutes Getting Clogged

Due to usage, muck can get formed, which can make the chute clogged.

Solution

  • By cleaning it thoroughly, anything formed in the chute should be removed via brushes or something similar. An air blower can also be used to remove dirt and other substances.

9. Over Heating Of The Engine

Another issue could be the overheating of the engine, which can be caused by the grasses as it would resist the engine from cooling down if it gets stuck in the fin.

Solution

If your mower has the option of a coolant, then you could check it from time to time.

10. Clutch Problems

While mowing, you might notice that the DR Brush Mower might not be at the same level of speed. That it used to be at when it was new. So, the problem could occur as the clutch  tends to wear the belt that powers the transmission from time to time.

Solution

This can be fixed with an adjustment; you can take up the slack, which can make the machine run as it used to at the beginning.
