What to do if my Toro Riding mower starter does not crank?
- A
  Anthony MaciasSep 8, 2025
  If the starter on your Toro Riding mower doesn't crank, it could be due to several reasons. The blade control (PTO) might be engaged, the parking brake might not be on, or the operator might not be seated. Other potential causes include a dead battery, corroded or loose electrical connections, or a blown fuse. If the relay or switch is defective, contact an Authorized Service Dealer. Here's how to troubleshoot: * Move the blade control (PTO) to disengaged. * Set the parking brake. * Sit on the seat. * Charge the battery. * Check the electrical connections for good contact. * Replace the fuse.
