Why Husqvarna MZ5424S Lawn Mower starter does not turn the engine over?
- B
  Bailey FryeAug 22, 2025
  If the starter on your Husqvarna Lawn Mower isn't turning the engine over, it could be due to a few things. First, the battery might be dead, so try charging or replacing it. Another possibility is poor contact on the battery terminal cable connections; cleaning and tightening these connections may help. Also, check if a fuse has blown and replace it if necessary. In some cases, the ignition system could be faulty, requiring repair or replacement. Finally, there might be a fault in the starter safety circuit, which would need to be checked.
