1. Mower Not Starting 

Undoubtedly it can be highly annoying to cope with a mower that refuses to start at all. 

If you are facing this issue, it is natural to be afraid, and you might think that now you have to buy a new mower.

But heave a sigh of relief because this problem can be rectified by cleaning or replacing the faulty parts of the mower.

Regarding causes, most mowers do not start when the fuel tank is empty or has insufficient fuel.

Moreover, if your mower’s carburetor cannot mix fuel and air, starting the engine can also be a big hurdle.

Another cause of this worrisome problem can be the spark plug, which fails to provide the spark.

Also, remember that faulty or clogged air and fuel filters can be the culprit.

It is also worth mentioning here that corroded battery terminals, electrical issues, and broken safety and ignition switches are also some potential causes.

Solution

To resolve the issue, you need to provide the mower with the required quantity of fuel.  

Once you’ve fixed the fuel issue, there is a big chance that your mower problem will be resolved.

After that, you must check the spark plug, carburetor, air, and fuel filters.

If any of them is clogged with residue or grease, clean them properly using the suitable method.

And, if you figure out that any of them is broken, replace them.

If the issue does not go even after sorting out the problems with the above-mentioned components, you need to inspect the battery, ignition switch, solenoid, and electrical connections.

Make sure all of them are rendering their job finely. If you figure out that any of these parts are damaged, then consider changing them.

2. Mower Emitting Smoke

Smoke emission from engines is usually due to blocked air filters or the low engine oil level.

Moreover, this issue can also spark if the crankcase has oil in excess or the carburetor is clogged.

Solution

The first thing you have to do is to clean the air filter accurately. If you let it dirty, then it can affect the air-to-fuel ratio.

As a result, fuel becomes dense, and smoke is released when it burns.

Besides that, if engine oil is low, providing more oil to the mower is significant.

Check the carburetor and clean it properly using a top-tier carburetor cleaning spray.

3. Mower Starts, Then Dies

Sometimes the mower may start, but then it dies and stops working. If your zero-turn is experiencing this issue, you must be frustrated and stressed.

But don’t panic; it’s a common problem, and you can solve it. Firstly you have to understand the main causes of this issue.

Usually, the main cause is contaminated oil or bad gas. Moreover, this issue can also arise due to damaged and clogged fuel lines.

Some other potential causes of the mower’s start-and-die issue can be damaged or dirty air filters or cooling fins.

Another noteworthy reason for this problem is the carburetor that has either got damaged or become dirty.

When it comes to the solution, this issue can hopefully be solved by replacing the oil.

But if the issue lingers, you need to check some components of the mower and try to assess its condition.

So, firstly check the carburetor, and you must ensure that it is not dirty or damaged. If you find any issue, try to sort it out without thinking twice.

If the fuel lines get contaminated or damaged, it can become a big obstacle to your mower’s smooth functioning.

So, you need to clean the fuel lines properly, and if they are in bad condition, replace them.

Lastly, it is imperative to carefully examine the air filters and ensure they can filter air.

4. Hydrostatic Transmission Issues

Hydrostatic transmission systems indeed play a vital role in the optimal performance of a mower.

But after excessive usage, it can weaken and influence the overall performance. In most cases, this issue is produced by low hydraulic oil.  

And if the drive belt has become loose or damaged, it can impact the hydrostatic transmission system.

Additionally, pulleys with no tension or lubrication can also spark this issue. Clogged fuel lines and fuel pumps are some other reasons.

Solution

To fix the problem, pour more hydraulic fluid and check the oil condition.

If you think it has become too old or dirty to work, replacement is surely the best choice.

After that, inspect the air filters and ensure they work accurately.

Also, don’t forget to check the transmission belt and pulleys. Ensure that the belt is secured tightly and undamaged.

Moreover, pulleys should also be lubricated and have sufficient tension.

5. Engine Overheating

Engine overheating is another prevalent issue that can appear in any mower, including Husqvarna.

This issue can surface due to the viscous or low quantity of fuel. Another potential cause of this problem is clogged or damaged cooling fins.

Solution

To get rid of this problem, it is imperative to inspect engine oil, and it should not be in less amounts or contaminated.

After that, you need to examine the cooling fins. If broken or clogged, they can not cool the engine and prevent overheating.

6. Uneven Cutting

Uneven or poor cutting is surely one of the biggest and most serious problems.

Particularly, if you are obsessed with lawn beauty and maintenance, then it can give you anxiety attacks.

But there is no need to freak out lawn beauty enthusiasts. You just need to assess the leading causes and then follow some steps to fix those issues.

Blunt, damaged, or bent blades are certainly the biggest culprit of uneven cutting. Misadjusted blades or unleveled decks are some other causes.

Additionally, deflated tires or tires with unequal pressure can make cutting grass evenly challenging.

It will help if you remember that poor cutting issues can also emerge due to damaged deck shells or bent blade spindles.

The defective deck belt or pulleys are the other probable causes of this problem.

Solution

Fixing this issue timely is crucial to restoring the performance of your mower.

So, the first step in this solution process is to inspect the blades, and if they have become dull, then it is important to sharpen them.

But sharpening will not be enough if the blades are damaged, so try to replace them.

After that, you need to examine the blade’s adjustment, which must be adjusted perfectly.

If the issue persists, you must confirm that the tires have equal pressure and are appropriately inflated.

Next, check the blade spindle and deck shell to ensure they perform efficiently.

Remember to inspect the pulleys and belts; if they have any flaws, sort them out.

7. Steering Issues

Steering issues are also prevalent in Husqvarna zero-turn mowers. And multiple causes can be involved in the appearance of steering issues.

You may encounter steering issues if your mower wheels are imbalanced or tires have unequal pressure.

Clutch issues or broken bushings, gaskets, damper, shafts, and bearings can cause steering problems.

Another potential cause of this problem can be the unleveled deck or issues in linkages of the steering system.

As far as the causes of vibration issues are concerned, they include drive belt or pulley fault, failing clutch, damaged blades, loose blade bolts overloading, or underloading.

Some other reasons are the spindle housing’s bearing issue and the external material stuck around the blade shaft of the mower.

Solution
