  If the starter on your Toro Lawn Mower doesn't crank, first ensure the blade-control switch is disengaged. Next, check that the motion-control levers are in the park position. If these are correct, the battery may be dead, so charge it. Also, examine the electrical connections for corrosion or looseness and ensure they have good contact. Finally, check the fuse and replace it if it's blown. If a relay or switch is damaged, contact an Authorized Service Dealer.
