  Mariah PerezSep 15, 2025
  If the starter on your Toro Lawn Mower isn't cranking, there are several things you can check: * Ensure the blade control switch is disengaged. * Make sure the motion control levers are in the park position. * Confirm that the operator is seated. * Check if the battery is dead and charge it if needed. * Inspect the electrical connections for corrosion or looseness. * See if a fuse is blown and replace it if necessary. If none of these steps work, a relay or switch may be damaged, and you should contact an Authorized Service Dealer.

  If you're experiencing abnormal vibration with your Toro Lawn Mower, start by checking if the engine mounting bolts are loose and tighten them. Also, inspect the engine pulley, idler pulley, or blade pulley for looseness and tighten as needed. If the engine pulley is damaged, or a blade spindle is bent, contact an Authorized Service Dealer. Furthermore, the cutting blade(s) might be bent or unbalanced, so you should install a new cutting blade(s). Finally, verify that the blade mounting bolt is tight.
