15 Common Problems with Husqvarna Riding Mowers

Husqvarna riding mowers, including their zero-turn models, are known for their efficiency and reliability in maintaining your lawn.

However, like any other machinery, they can sometimes face issues that can affect their performance.

In this article, we’ll discuss some common problems you might encounter with your Husqvarna riding mower and potential solutions to help you get your mower back in peak working condition.

Use the drop-down below to skip to a particular problem:

Common Engine Problems

Dirty Carburetor

A dirty carburetor can cause your Husqvarna riding mower’s engine to experience trouble starting or running poorly. This happens when debris or old fuel builds up inside the carburetor, hindering the flow of the fuel-air mixture.

To fix this, you can:

  • Use a carburetor cleaner, spraying it into the carburetor while the engine is running.
  • Disassemble and clean the carburetor with the cleaner if the issue persists.

Clogged Air Filter

A clogged air filter can decrease your mower’s engine performance, leading to poor fuel efficiency or making it hard to start.

You should:

  • Inspect the air filter regularly.
  • Clean it if it’s mildly dirty, or replace it if it’s damaged or excessively dirty.

Bad Spark Plug

A bad spark plug can cause many engine issues, such as poor starting or misfiring.

To check for a faulty spark plug, you should:

  • Inspect the spark plug for damage, deposits, or worn-out electrodes.
  • Replace it if necessary.

  • Fits various Husqvarna String Trimmers and Chainsaws

Engine Oil Level

An incorrect engine oil level can lead to engine damage or reduced performance.

To maintain proper engine oil level, you need to:

  • Check the engine oil level before each use.
  • Add oil whenever the level is low, but be careful not to overfill.

Cooling Fins

Dirty or damaged cooling fins can cause your engine to overheat, which can lead to severe damage.

To keep your cooling fins in good condition, make sure to:

  • Keep them free of grass clippings and debris.
  • Clear away any buildup with a soft brush or compressed air.
  • Inspect the fins for damage and replace them if necessary.

Starting and Ignition Issues

Mower Not Starting

One common issue you may face with your Husqvarna riding mower is that it may not start.

There could be several reasons for this, such as:

  • Lack of fuel: Check if there is enough fuel in the tank.
  • Bad spark plug: Inspect the spark plug for any damage or carbon deposits. Replace it if necessary.
  • Clogged fuel filter: If there’s an issue with the fuel flow, consider checking the fuel filter for any clogs.

Faulty Ignition Switch

Another issue you might encounter is a faulty ignition switch. To determine if this is the cause, you should test it with a multimeter. If there’s no continuity in the switch’s internal circuits, it’s time to replace it.

Here are some indicators of a faulty ignition switch:

  • Intermittent starting: If your mower starts occasionally, but not every time, it could point to an issue with the ignition switch.
  • No response when turning the key: If there’s no sound or movement in the electrical components when you turn the key, the ignition switch might be the culprit.

Dead Battery

A dead battery is also a common reason for starting and ignition issues in your Husqvarna riding mower. To identify this problem, you can check the battery voltage using a multimeter. A fully charged battery should have a voltage between 12.5 to 13.0 volts.

  • Charge the battery: Use a battery charger to restore its charge.
  • Check the connections: Ensure that the battery terminals are clean and firmly connected.
  • Consider a replacement: If your battery is old or has been problematic in the past, you may need to replace it with a new one.

Fuel System Problems

Clogged Fuel Lines

One common problem with Husqvarna riding mowers is clogged fuel lines. If your mower has difficulty starting or stalls during operation, it could be due to a clogged fuel line. Debris, such as dirt, grass, or rust, can accumulate in the lines, restricting the flow of fuel to the engine.

To resolve this issue:

  • Check the fuel lines for any visible blockage
  • Replace any damaged or cracked lines
  • Use an air compressor to blow out the lines
  • Replace the fuel filter, as it may be clogged

Bad Fuel Pump

Sometimes, the fuel pump in your Husqvarna riding mower might cause problems. A bad fuel pump can lead to poor performance, the inability to start, or stalling during operation.

  • Check for loose wiring connections on the pump
  • Listen for unusual noises coming from the pump area
  • Use a fuel pressure gauge to check the pump pressure
  • Inspect the pump for any visible damage or corrosion
  • If necessary, replace the fuel pump

Fuel Tank Ventilation

Another issue could be the fuel tank ventilation. A clogged vent or a malfunctioning gas cap can cause fuel starvation, leading to your mower’s engine stalling or underperforming.

To address this problem:

  • Inspect the gas cap and make sure it is sealing properly
  • Check the vent for any visible blockage or dirt
  • Clean the vent using a small brush or compressed air
  • If the gas cap shows signs of wear or damage, replace it
