3. Checking the drive pulleys

If you’ve been having trouble with your Husqvarna self-propelled lawn mower, you might want to check the drive pulleys.

The drive belt passes over three different pulleys, including the clutch pulley. If any one of the pulleys is off balance, the power transmission will suffer. Checking the drive belt’s tension can help fix the balance problem.

Check the belt tension by removing the belt. Next, check the drive pulleys for free rotation.

Any excessive friction will cause the belt to wear faster. If the pulleys are damaged, replace them. If the pulleys are damaged, the cable may come off the bottom.

Keeping these tips in mind can help you identify possible problems before they happen.

The drive pulleys connect the engine to the wheel assembly. If one is damaged, the drive pulley will no longer turn the lawn mower’s wheels. If the drive pulley is worn, replace it.

In addition, the drive cable is susceptible to damage, so it’s worth checking the cable frequently. Check the cable’s condition, and lubricate it with WD40 or a similar fluid.

A loose bearing in the tensioner pulley may cause your Husqvarna lawn mower to not move. Another cause for this condition is an incorrectly aligned idler spring or bushing.

Check the drive pulleys for Husqvarna self propelled lawn mower problems by following the instructions on the owners manual. If necessary, you should take your mower to a Husqvarna dealership for repair.

A broken or misplaced drive belt can cause the blades to stop turning. A broken drive belt can also be a cause for your Husqvarna self-propelled lawn mower problems.

If you are unsure, you can try re-tensioning it with a wrench. Make sure the belt is properly mounted. If the belt is too loose or is loose, the blades will stop turning.

4. Checking the oil

In addition to the obvious check of the oil level, there are a number of other potential Husqvarna self propelled lawn mower issues that can cause an uneven cut.

These include a plugged air filter, a dirty carburetor, and a malfunctioning safety switch. In some cases, your mower may simply not start. In these cases, a trip to your local Husqvarna dealer is necessary.

If you see black smoke coming from the engine, the cause of this problem is likely the engine running too richly. In other cases, the mower may be shaky because of debris caught in the spindles and under the pulleys.

If you notice these issues, contact the nearest service center or mechanic. If none of these steps solves the problem, you should try a different solution.

If the mower is experiencing excessive vibrations, the cause could be a bearing failure. The other possible culprit is a broken linkage or bushing.

5. Damaged Blade

Some Husqvarna self propelled lawn mower problems may be as simple as a damaged blade. If debris has wrapped around the blade shaft, you should remove it and balance it.

Also, if the blades are too bent or the blade shaft is overly tight, you should balance them.

If your Husqvarna self-propelled lawn mower isn’t cutting grass is because the blade isn’t aligned properly. The problem could also be caused by a damaged deck shell, an uneven blade, or an incorrectly-installed blade adapter.

If you can’t find a replacement, you can purchase one online.

6. Checking the drive cable

If your Husqvarna self propelled lawn mower isn’t moving forward at all, you might be experiencing a problem with the drive cable.

Drive cable is a part of the self-propelling switch, which activates the transmission that pushes the mower forward.

Sometimes this cable can be faulty, and you’ll need to replace it. To check the drive cable, turn the drive control lever on the handle, pull the drive cable back.

Then, start the mower to test the speed. If you still cannot start the machine, you might be experiencing a problem with the transmission.

In some cases, the drive cable is too tight, so make sure it is firmly attached to the mower.

Also, it’s possible that the drive cable has become elongated. It’s a good idea to check the cable alignment before you attempt to fix a problem with your self propelled lawn mower.

Often, minor adjustments to the cable will fix the problem.

The drive cable in your Husqvarna self-propelled lawn mower is normally adjustable. Over-aggressive cutting of grass can cause the drive cable to shift and affect its mowing ability.

If you notice any of these symptoms, you should immediately contact a professional lawn mower repair service. To avoid this, read this article carefully to ensure you are properly adjusting the drive cable.

7. Checking the engine’s compression

If you notice the engine running hot but does not start, it’s probably a mechanical issue. It’s possible that the engine is overheating, but you should never attempt to fix it yourself.

Instead, you should replace the mower if it’s more than ten years old.

It might be the result of poor maintenance, or it might simply be the cause of the problem.

The spark plugs on combustion engines have a small gap between their electrodes. When air and gasoline mix, a spark jumps across the gap and causes combustion.

However, if the spark gap is too small, it won’t ignite the mixture properly. If this happens, the engine will shut down.

To remedy this problem, you should clean the engine and make sure its components are properly lubricated.

8. Damaged Spark Plug

Another cause of Husqvarna self propelled lawn mower issues is a damaged spark plug.

You can easily check the spark plug by inserting a meter and measuring it at the opposite tip.

The difference should be one eighth inch or less. If the spark plug is not in place, it could be causing excessive vibration.

If the spark plug is faulty, it should be replaced.

If the cylinder head and intake gaskets are not the culprit, then the cylinder head and inlet gaskets are likely to be the problem.

In such cases, it’s more economical to replace the engine.

However, if the compression test is not enough, a replacement engine is the best option. However, it’s worth it to spend the extra money to replace a worn engine.
