Why Toro Z355 Z-Master starter does not crank?
- D
  David LopezAug 18, 2025
  The starter may not crank on your Toro Lawn Mower due to several reasons. The power take off (PTO) might be engaged, so move it to disengaged. Ensure the parking brake is set and the motion control levers are in neutral. Check if the battery is dead and charge it if necessary. Also, verify that electrical connections are not corroded or loose and that the fuse is not blown. If the relay or switch is defective, contact an Authorized Service Dealer.

  If your Toro Lawn Mower engine won't start, starts hard, or fails to keep running, check the following: * Ensure the fuel tank is filled with gasoline. * Move the choke lever to the ON position. * Clean or replace the air cleaner element if it's dirty. * Install the wires on the spark plug if they are loose or disconnected. * Install new, correctly gapped spark plugs if the current ones are pitted, fouled, or have an incorrect gap. * Replace the fuel filter if it's dirty.

  There are several reasons why your Toro Lawn Mower engine might not start. It could be due to an empty fuel tank, so fill the tank with gasoline. The choke may not be on, so move the choke lever to the ON position. A dirty air cleaner can also cause this issue, so clean or replace the air cleaner element. Check if the spark plug wires are loose or disconnected and install them on the spark plug. The spark plugs might be pitted, fouled, or have an incorrect gap, in which case you should install new, correctly gapped spark plugs. Also, check for dirt in the fuel filter and replace it if necessary. Finally, make sure the fuel shut off valve is turned to the 'on' position.
