If you have debris or grass clogging your cutting deck, this problem can lead to serious consequences.

Here are the 3 most common Dr. Brush Mower Problems:

1. Engine overheating

If you notice that your Dr. Brush mower engine is overheating, you should look for a few different issues. Low oil level is usually the culprit, as it will increase friction and temperature.

Another key cause is blocked cooling fans. Grass and debris can block the fins, preventing cool air from flowing into the engine.

Check the coolant level, if the mower has one. If the problem persists, contact the manufacturer for a repair.

A bent or loose mower blade can cause the engine to overheat. In addition to poor cutting efficiency, it will also put more strain on the motor or engine. It is vital to inspect the blade for any damage or bent parts.

If the blade is bent or loose, you will need to replace it. It is also a good idea to keep the grass cutting deck free of debris. If the blades are rusted or bent, you will need to replace them.

A failed thermostat may be to blame. Most gas engines operate best with a 14.7:1 air-fuel ratio. A properly functioning engine has an air filter to prevent dirt and debris from getting into the engine.

However, these filters get dirty over time. A dirty filter will prevent the engine from getting the proper air needed for combustion. A lack of air will result in the engine struggling to run properly and could overheat.

Besides the fuel filter, other components of a Dr. Brush mower are also important to maintain. Changing the fuel filter every month and using a fuel stabilizer will help.

You should also clean the spark plugs. This is vital because dirt and debris can cause serious problems later.

Further, the blades must be sharpened and maintained regularly to prevent them from rusting and getting damaged. This can lead to premature engine wear and tear.

2. Smoke from clogged air filter

When you see white or blue smoke coming from your mower’s exhaust, you may have a clogged air filter.

The dirty air filter is probably causing the mower’s engine to burn too much fuel, which is resulting in smoke.

Replace the air filter to solve the problem. If you continue to notice smoke, you may need to contact a professional mechanic. If you see this problem on a regular basis, you should immediately take it to a mechanic.

If you’re experiencing black exhaust smoke, your lawn mower’s air filter may be clogged. This will prevent it from getting enough air to start the engine.

Check your owner’s manual for directions on how to clean your air filter. If your air filter is dirty, it’s time to replace it. In addition, you should check the angle of your lawn mower while mowing.

Another sign of a clogged air filter on your lawn mower’s engine is smoke. If you notice smoke coming from the exhaust of your Dr. Brush lawn mower, the air filter may be clogged.

A clogged air filter can damage your lawn mower’s engine and result in a smokey, sputtering engine. Moreover, a dirty air filter will waste more gas to cut the same amount of grass.

In addition to a clogged air filter, a drained spark plug can cause smoke from the engine. You should replace your spark plugs frequently and use a fuel stabilizer if necessary.

Clean the air filter in your Dr. FIELD AND BRUSH MOWER regularly to prevent engine malfunction. If you continue to notice smoke from the exhaust, replace the air filter as soon as possible.

3. Deck clogging

One of the most common lawn mower problems is a clogged chute. Grass that is too dry or built up on the mower deck will cause the chute to clog. You can clean it using water, forced air, or even bed liner. However, if you cannot get the chute clean, consider replacing the mower altogether. A clogged chute may be a sign of a more serious problem.

To clean your mower deck, remove any accumulated muck that has built up on it. Use a stiff brush to clean the deck and blade bearing housing. Clean the blade bearing housing.

Check for nicks, and sharpen if necessary. You can also use a professional blade sharpener to make it as sharp as possible.

Begin on page 17 for proper lubrication and blade maintenance. To ensure the smooth performance of your lawn mower, follow the maintenance instructions provided with the product.

In addition to cleaning the deck, you need to keep an eye on the fuel level. Low fuel levels will affect your mower’s performance.

The fuel to air ratio will be too high, which will lead to smoke. Smoke can also occur due to a clogged air filter. Using a gas-powered lawn mower will result in smoke if the engine is running low on fuel. The fuel level is usually the cause.

Diagnosing Dr. Brush Lawn Mowers

To start, check the wiring harness. This wiring harness runs from the handlebar and control panel area into the main chassis frame and terminates at the engine at a connector plug.

I used a continuity test and found that 12 volts were not reaching the fuel solenoid. However, the wiring harness is inaccessible inside the chassis, so I was able to remove the entire harness and test the connections by cutting zip ties.

I was able to determine that the connector had become corroded and the wiring had partially been cut through.

The air filter and fuel tank of the mower are two common causes of smoke. Sometimes, a clogged air filter and a dirty carburetor can also cause this problem.

If you notice that your dr brush mower has a high fuel level, check the fuel level first. A high fuel level can also cause smoke.

A clogged air filter will increase the fuel-to-air ratio. Another possible cause of smoke is a loose blade carrier.

Always make sure that the blade carrier is sharp and replace it when worn.
