10 Most Common Husqvarna MZ54 Problems and Their Possible Solutions
1. Blades Won’t Engage
Several MZ54 users have reported blade engagement issues where the mower blades won’t engage. If the blades don’t engage, you might be able to take use of the mower.
If the blades are not engaging, there could be two possible components that are causing the issue, either it could be the PTO clutch or the switch, since both of these components are responsible for providing power to the blades.
The PTO or power take-off clutch allows the engine to connect and get power from the drive belt to rotate the blades. If the clutch gets worn out or broken, the process will not take place, causing the blade’s engagement issue.
Solutions:
If your Husqvarna MZ54 mower blades are not engaging, there are a few steps you can take to try and resolve the issue. Firstly, make sure the PTO clutch isn’t damaged or worn out. If the clutch is damaged, you need to replace it.
After that, check the PTO switch. If the PTO switch appears to be faulty, the blades won’t engage. You can use a multimeter to check a faulty switch. If the switch is faulty, it will need to be replaced.
Apart from this, you may also need to replace or reinstall the drive belt if it is not mounted properly or in case it has been damaged.
2. Starter Doesn’t Turn The Engine Over
Another common issue with the Husqvarna MZ54 is that the starter doesn’t turn the engine over. This happens whenever there is a maintenance issue with your mower. You will need to check a few components if you are facing this issue with your mower.
Solutions:
To ensure the proper functioning of your Husqvarna MZ54, there are a few steps you should take before starting it up.
Firstly, it’s essential to make sure that the freewheel control lever is in the “Engaged” position. This is important because it allows the mower to move freely and engage with the engine.
Additionally, make sure to disengage any attachment clutch that may be connected to the mower to avoid overloading specific components such as the Kohler 26HP engine.
Another important step is to keep the control level neutral before starting the mower. This helps to prevent any unnecessary strain on the engine or other components that could potentially lead to damage.
In case this does not resolve your issue, you might have a dead battery, blown fuse, or battery terminals that are corroded, and the cables are not in contact with the battery, causing the issue.

To fix the overheating problem, you need to check the cooling fins and air intake of the mower. If the cooling fins are clogged, or the air intake is blocked, you need to fix it by cleaning.
