10 Most Common Husqvarna Hydrostatic Drive Problems
Maintaining a power tool can take time and effort for beginners. However, this maintenance helps to lengthen the lifespan of the power tool. Like every other power tool, the Husqvarna mower has its problems.
Let’s take at some of the most common Husqvarna Hydrostatic Drive problems and how to solve them.
1. Hydraulic Fluid Leak
One of the most common problems with hydrostatic drive systems is a hydraulic fluid leak, which can happen due to worn-out seals or damaged hoses.
To fix this issue, you need to follow these steps.
- You need to identify the leak’s source and replace the faulty part.
- You can locate the leak by inspecting the hoses, fittings, and pump.
- Once you pinpoint the leak, you can replace the defective seals or hoses.
2. Creates Noise During the Operation
If your Husqvarna hydrostatic drive system makes noise during operation, it could be due to air in the hydraulic lines, worn-out bearings, or damaged gears.
First, ensure the hydraulic fluid level is correct to fix this issue. If the fluid level is okay, check for air in the lines and bleed the system.
3. Doesn’t Respond to the Shifting
If your mower doesn’t respond to the shifting, it could be because of damaged gear or a worn-out belt.
Here are a few steps on how to fix it.
- First, check the belt tension; if it’s too loose, you may need to adjust or replace it.
- If the belt tension is okay, check for any damage or cracks on the gears and replace the damaged parts.

4. Stalls When Accelerating
Stalling when accelerating can be due to a clogged fuel or dirty air filter.
To fix this issue, replace the fuel filter and clean the air filter. Ensure the carburetor is clean and the fuel tank is free from dirt and debris.
5. Air in the Fluid Lines
If you hear a banging noise or experience a shaky start, this could be due to air in the hydraulic fluid lines.
- To fix this issue, you must bleed the system and ensure no air in the fluid lines.
- You can do this by running your mower for a few minutes and then checking the hydraulic fluid level.
6. Dirt in the Transmission
Dirt or debris may get stuck in the transmission, leading to poor performance and even damage in the long run.
To solve this problem, clean the transmission system regularly. You could remove the transmission casing and clean the gears.
7. Mower is Stuck, Not Going Forward and Backward
One of the major problems you might encounter with your Husqvarna mower is that it might get stuck and won’t go forward or backward.
A simple solution to this problem is to check the drive belt. The drive belt might need to be fixed or worn out. If it is loose or worn out, simply adjust or replace the belt as necessary.
8. Husqvarna Mower Not Starting
This problem could cause by reasons, including a dead battery, faulty spark plugs, or an empty fuel tank. Diagnosing the root of the issue as soon as possible is important to prevent further damage to your mower.
The quick solution is to replace the battery to clean the carburetor. With a little effort and some troubleshooting, you’ll return to a perfectly running mower in no time.
9. Blade Brake Could Fail
The blade brake is an essential component of the Husqvarna mower. This component helps to stop the blades from rotating when you release the blade control lever. One common problem with the blade brake is that it could fail.
To solve this problem, inspect the brake pads and lever for wear or damage. Replace the brake pads or lever if necessary.
10. The Engine is Failing – Not Working Properly
The last problem with the Husqvarna mower is that the engine might fail to work properly. Several factors, such as a dirty air filter, a clogged fuel filter, or a bad spark plug, could cause this.
However, you can take a few quick and simple steps to try and fix the issue yourself without breaking the bank.
- Double-check your spark plug to ensure it’s not dirty or corroded, which can cause engine problems.
- Check your air filter and clean it if it’s dirty, as a clogged filter can cause engine issues.
- Ensure your blades are properly attached and tightened, as loose blades can cause issues with your mower’s overall performance.
You can quickly restore your Husqvarna mower’s function by performing these basic checks and troubleshooting the problem.
