There’s nothing more frustrating than your mower refusing to start.

Let’s delve into some causes behind these stubborn starts.

  • Not Enough/Bad Oil

Like any machine, mowers thrive on proper lubrication. Running it with insufficient engine oil is a recipe for trouble.

  • Defective Spark Plugs

A spark plug in poor condition is a sign that your mower’s ignition coil is faulty and can halt the ignition process. Signs of wear, rust, or deposits mean it’s time for a replacement. 

  • Dirty Fuel Filter

A fuel filter ensures only clean fuel reaches the engine. Over time, this filter can become clogged, starving the engine of the fuel it needs.

  • Dirty/Clogged Parts

Your mower’s carburetor and air filter can get clogged with debris, especially after long inactivity, hindering the starting process.

  • Dead Battery

All batteries have an expiry date. An expired battery could be the suspect if your mower’s electric start isn’t responding.


Begin by ensuring your mower has a good oil level and quality.

Next, give the spark plug a look—replace it if worn.

Check your fuel filter for blockages and ensure the carburetor and air filter are clean.

If all else seems fine, it might be time to invest in a new battery or give the old one a good charge.

2. Fuel system malfunctions

Fuel is the lifeblood of your mower, ensuring it hums across your lawn. But when the fuel system goes awry, it disrupts the entire operation. 

Common fuel-related issues.

  • Clogged Fuel Lines

Debris or stale fuel can build up, creating obstructions. This blockage impedes the free flow of fuel to the engine, preventing the mower from starting.

  • Bad Fuel Pump

The pump ensures the transportation of fuel from the tank to the engine. A malfunctioning or broken pump leads to poor performance or a non-starting mower.

  • Fuel Tank Ventilation

The mower’s fuel tank requires ventilation. Without this, a vacuum can form in the tank, preventing fuel from reaching the carburetor.


Start by inspecting the fuel lines. Ensure they’re clear of obstructions. Also, consider replacing them if they’re old or showing signs of wear.

Testing or replacing the fuel pump might be in order if your mower struggles with fuel delivery. Finally, check the fuel tank cap for any blockages. 

3. Drive and transmission complications

Common Problems With Husqvarna Riding Mowers

The drive system and transmission are the heart and soul of your mower’s movement.

They ensure seamless transitions and smooth rides. Yet, like any vital component, they’re not immune to issues.

Among the common culprits are:

  • Drive Belt Problems

The drive belt is essential for your mower’s transmission’s lifeline. Over time, this belt can slacken, fray, or even snap due to exposure to the elements. 

Signs of a failing belt include:

  • Strange noises
  • Jerky movements
  • Complete inability to move despite a running engine.


If you suspect drive belt troubles, start by turning off and inspecting your mower.

Check the belt’s tension and integrity. If it appears slack or shows visible signs of damage, it’s time for a replacement.

4. Husqvarna mower cutting deck problems.

The cutting deck can encounter issues that dampen its efficiency. These parts and the attachment clutch are pivotal for a consistent mowing experience.

Challenges you might face:

  • Mower Deck Issues

Overgrown grass, buildup of debris, or even rusty and dull blades can hamper its performance.

An uneven cut or a noisy operation often hints at potential deck problems.

  • Attachment Clutch Problems

The attachment clutch ensures the mower blades engage and disengage well.

Wear and tear, along with dirt accumulation, can hinder its operation. Symptoms include blades that don’t rotate when activated or a clutch that sticks.

You can also learn why Husqvarna Mower dies when the blades are engaged.


For deck issues, begin with a thorough cleaning. Remove accumulated grass, dirt, and any potential obstructions.

Check the blades: sharpen if they’re dull and replace if damaged. Balanced blades ensure an even cut.

As for the clutch, regular inspections can help spot problems early. If the clutch appears worn out or doesn’t engage, consider replacing it.

Regular cleaning and periodic inspections can keep both these components in shape.

5. The mower stops during the operation.

Sudden halts or engine shutdowns are often attributed to a variety of reasons:

  • Overheating

Like any other machine, mowers can overheat, especially on hot days or when running for extended periods.

  • Fuel Issues

Running out of fuel, water-contaminated fuel, or a clogged fuel line can all lead to sudden stops.

Test the PTO switch for continuity. If it’s faulty, replace it. Ensure all connections are secure.

Inspect the clutch and belts. It might be time for a replacement if it’s worn or doesn’t engage.

Disconnect the spark plug, then inspect and clear any obstructions around the blades.

Ensure all safety features are in their correct positions. Ensure you only try to engage blades in reverse if your mower supports it.

7. Mower emits smoke

Common Problems With Husqvarna Riding Mowers

Nothing raises alarm faster than seeing smoke billow from your Husqvarna mower. While panic-inducing, smoke usually indicates a fixable problem.

Signs and Causes:

  • White or Light Blue Smoke

This type of smoke often signals oil burning in the engine. It can occur if the mower has too much oil or is tilted, allowing oil to enter the combustion chamber.

  • Black or Dark Smoke

Dark smoke suggests a rich fuel mixture, often due to a clogged air filter, dirty carburetor, or a stuck choke.

  • Blue Smoke

Consistent blue smoke can mean worn engine parts. It thus allows oil into the combustion chamber.

  • Continuous Smoke

If your mower smokes, there could be prolonged issues like damaged cylinders or worn rings.

  • Mixed Color Smoke

A combination of problems can cause the mower to emit mixed color smoke.


Drain excess oil if overfilled. If the mower is tilted, allow it to sit level before restarting.

Replace or clean the air filter. Inspect the carburetor and choke for proper operation. Adjust the fuel mixture if necessary.

Inspect engine components like the piston rings, seals, and gaskets. Replacements might be necessary.

8. Weak hydrostatic transmission

The hydrostatic transmission in your Husqvarna helps your mower run. But if it starts acting up, your mowing can get rough. 

Why It Gets Weak:

  • Not Enough Fluid

If there’s not enough fluid, it won’t squirt right. Your mower’s transmission needs enough fluid to work well.

  • Old or Dirty Fluid

Over time, the fluid can get old or dirty, making your mower work harder and harming it.

  • Bad Belts

These belts help your mower move. If they’re old or broken, your mower might move slowly or not at all.

  • Worn-out Parts

The parts inside the transmission can wear out, making your mower noisy or stopping it from moving.


It’s essential to keep an eye on your mower. Regularly inspect the fluids and belts, ensuring they’re in good shape.

Notice the fluid getting dirty? Time for a change. And if a belt appears worn out or damaged, replace it promptly. 

9. Movement and steering problems

Sometimes, Husqvarna riding mowers might move differently than expected. Or, they could have trouble turning. Here’s why this happens:

  • Tire Troubles

Like on a bike or car, steering can get tricky if your mower’s tires need to be inflated right or worn out.

  • Broken Steering Gear

Inside your mower, there’s a part that helps it turn. If it breaks, turning gets tough.

  • Loose Belts

Belts make the mower move. If they’re not tight or they break, your mower might not move at all.

  • Worn-out Wheel Spindles

These parts help the wheels turn. If they’re old or damaged, your mower might not go straight.

  • Transmission Issues

If the hydrostatic transmission fails, your mower might not move forward or back.

  • Jammed Steering Column

A jammed steering column means it’s stuck and won’t turn. Fix it to steer safely again.


Always keep an eye on your mower’s tires, making sure they’re properly inflated and undamaged.

If you’re facing steering problems, it may be time to replace the steering gear.

Either tighten or replace belts and wheels that appear loose. Remember the transmission; ensure it’s running smoothly.

Sometimes, a quick fluid change or fixing a leak does the trick. And if you can’t steer right, it could be a jammed column, so ensure it’s unlocked.

10. Vibration and cutting issues

Nothing ruins a mowing session faster than a mower that shakes. You’re aiming for a smooth operation, but sometimes things go haywire.


  • Unbalanced Blades

Mower blades can become unbalanced due to wear or damage, leading to a wobbly spin.

  • Worn-out Bearings or Spindles

These parts help the blade spin. If they’re worn out, you’ll feel more shake, rattle, and roll than you’d like.

  • Dull Blades

A blade that isn’t sharp won’t cut clean. Instead, it may tear or pull at the grass.

  • Deck Leveling

If the mower deck isn’t level, it can result in uneven cutting.

  • Loose Engine Mounts

The engine should be firmly attached. If mounts become loose, the whole mower can shake.


Ensure your blades are balanced. If they’re damaged, it’s best to replace them. Check for wear and tear and replace if necessary.

Sharpen or replace dull blades to ensure a clean cut.

Always adjust the deck to ensure your mower deck is level for an even cut across your lawn.

Tighten engine mounts to secure any loose engine mounts to reduce vibration.

11. Gas leakage

Gas leaks aren’t just wasteful; they can be hazardous, too.

Causes for Gas Leakage:

  • Damaged Fuel Lines

Over time, the fuel lines can wear out, crack, or get punctured, leading to leaks.

  • Loose Connections

Sometimes, the connectors between the fuel lines and the engine or tank can become loose.

  • Faulty Fuel Cap

Fuel can leak if the cap doesn’t seal properly, especially when the mower is tilted.

  • Cracked Fuel Tank

A damaged fuel tank, even with a tiny crack, can result in gas leaks.

  • Overfilled Tank

Pouring in more fuel than the tank can hold is a common mistake that leads to spillage.

  • Degraded Gaskets

Gaskets seal off various components. If they degrade, they might allow fuel to seep out.


Periodically inspect the condition of the fuel lines. If you notice any damage, replace them.

Ensure all connections in the fuel system are tight and secure. Get a new fuel cap if the existing one isn’t sealing well. Also, replace the fuel tank if there are damages.

Avoid overfilling; always leave a little space when filling up the tank. Gasoline expands, especially in heat, and needs room. 

Replace gaskets for a secure seal if you suspect a gasket is worn out.

12. Battery issues

Ever been all set for mowing, only to turn the key and face a dead silence? Yep, we’re talking about battery troubles.

Causes for Battery Issues:

  • Expired Battery

Mower batteries have a lifespan like all batteries. After a certain number of charge cycles, their efficiency drops.

  • Corroded Terminals

The metal terminals of a battery can corrode over time. Prevent efficient energy transfer.

  • Loose Connections

A battery’s connection might become loose or disconnected, inhibiting power flow.

  • Faulty Alternator

Husqvarna riding mowers have alternators that recharge the battery as the mower runs. If it’s defective, the battery won’t recharge properly.

  • Improper Storage

 Storing the battery without a trickle charger can reduce lifespan.


If your mower’s battery is ageing or failing to hold its charge, it might be time to invest in a new one.

Keeping the terminals clean to clear away any corrosion. Replace the alternator should you notice the battery running out swiftly.

Unexpected power drains may need a thorough look into the wiring and switches. Store the battery in a cool, dry environment. 

13. Husqvarna carburetor malfunctions

Common Problems With Husqvarna Riding Mowers

When the carburetor goes awry, your mower’s performance can dip drastically. Here are the signs of a troubled carburetor:

  • The mower refuses to start or has a hard start.
  • It might stall frequently during operation.
  • You could notice a surge in the mower’s speed or an uneven running.
  • Excessive fuel consumption or fuel leaks.


Over time, dirt, debris, or stale fuel can clog the carburetor. A thorough cleaning using carburetor cleaner can often bring it back to life.

If the mower isn’t running, it might be due to an improper air-fuel mixture. Adjusting the screws on the carburetor can help fine-tune this balance.

Worn-out or damaged gaskets can cause air leaks. Ensure they’re in good shape, or replace them if needed.

A stuck or damaged needle valve can cause flooding or restrict fuel flow. Make sure it moves and is not worn out.

14. Air filter oil contamination

One of the issues in your mowing plans is the air filter contamination with oil. There’s usually a straightforward explanation behind it.

Why It happens:

  • Overfilling the Oil

Never overfill your mower. Too much oil in your mower tries to find its way into the air filter. 

  • Tipping the Mower

During maintenance or cleaning, you might tip the mower in a direction that allows oil to flow into the air filter.

  • Faulty Crankcase

If the mower’s crankcase is not functioning well, it might not vent, pushing oil into the air filter.


The first step is always to check the oil level. If it’s above the recommended limit, drain some out.

When tipping the mower, ensure you’re doing it in a direction that keeps the oil away from the air filter. Tilting it carburetor-side up is a safe bet.

If the air filter is soaked in oil, it’s essential to clean it thoroughly. If it’s too drenched, consider replacing it.

Ensure that the crankcase is venting correctly. If you suspect it’s faulty, it might need professional attention.

15. Mower’s slow speed

A sluggish mower is so frustrating. What makes it act this way?

  • Drive Belt Wear

The drive belt can become worn out or loose. When this happens, it doesn’t transfer efficient power.

  • Clogged Transmission

Dirt and debris can enter the mower’s transmission system, leading to slow operations.

  • Low Tire Pressure

Like a car, if the mower’s tires are not inflated, it can affect the speed.

  • Thick Grass or Overloaded Deck

Mowing a deck filled with clippings can slow down your machine.

  • Worn-out Drive Cables

Over time, the cables controlling speed can stretch or wear out, causing a drop in mower speed.


Inspect the drive belt often. If it’s worn or loose, it’s time for a replacement.

Periodically ensure that the transmission is free from dirt and debris. If necessary, consider getting a professional cleanup.

Check the tires for proper inflation and fill them to the recommended level.

Regular mowing prevents the grass from growing too thick. Regular emptying of the mower deck ensures it’s manageable.

Replacing them can restore the mower’s speed if stretched or damaged.

16. Engine overheating

Engine overheating in your Husqvarna mower affects the machine’s performance.

An overheating engine in your Husqvarna mower may emit white or blue smoke or produce a knocking sound. 

Causes of Engine Overheating:

  • Low Coolant Level

Insufficient coolant in the system can lead to overheating.

  • Clogged Cooling Fins

Dirt and debris can accumulate, preventing proper air circulation.

  • Faulty Thermostat

A malfunctioning thermostat can fail to regulate the engine’s temperature.

  • Damaged Water Pump

The water pump won’t circulate the coolant effectively if it isn’t working.


To stop your mower from getting too hot, check the coolant and top it up if it’s low.

Clean any stuff stuck in the cooling system. You might need a new one if your thermostat isn’t working right.

Avoid mowing thick grass or using the mower often when it’s hot outside, making it overheat.

17. Faulty steering mechanisms

Steering your Husqvarna mowers should feel effortless. But when the steering goes awry, it can be a safety concern. 

Common causes:

  • Worn-out steering gear

A worn-out gear might not catch well, making steering unresponsive.

  • Damaged or misaligned wheels

Misaligned wheels can cause the mower to drift.

  • Loose or broken steering components

Loose or broken steering components cause the mower to jerk unpredictably.
