    How to troubleshoot loss of drive on a Husqvarna YTH24K48?
    • D
      david26Sep 6, 2025
      If your Husqvarna Lawn Mower is experiencing a loss of drive, ensure the freewheel control is in the 'engaged' position. If equipped, check for debris on the steering plate. A worn, damaged, or broken motion drive belt could also be the cause, so replace the motion drive belt. Additionally, air trapped in the transmission during shipment or servicing might be the issue; purge the transmission. Finally, check for a missing axle key at the rear wheel and install it.
