Why Toro LX420 13AX60RG744 Lawn Mower engine fails to start?
- D
  Damon PearsonAug 13, 2025
  There are several reasons why your Toro Lawn Mower engine might fail to start: * The PTO (Blade Engage) lever may be engaged, so place it in the OFF position. * The parking brake might not be engaged; make sure to engage it. * The spark plug wire could be disconnected; connect it to the spark plug. * The throttle/choke control may not be in the correct starting position; move it to the CHOKE position. * The fuel tank may be empty or the fuel stale; fill it with clean, fresh gas (less than 30 days old). * A blocked fuel line could be the issue; clean the fuel line or replace the fuel filter. * The spark plug could be faulty; clean, adjust the gap, or replace the plug. * The engine might be flooded; crank the engine with the throttle in the FAST position.

What to do if my Toro LX420 13AX60RG744 will not mulch grass?
- P
  Patrick KramerAug 16, 2025
  If your Toro Lawn Mower isn't mulching grass effectively: * Ensure the engine speed isn't too low by placing the throttle in the FAST position. * Avoid mowing wet grass; wait until it's dry. * If the grass is excessively high, mow once at a high cutting height, then again at the desired height, or make a narrower cutting swath. * Check for a dull blade and sharpen or replace it.

What to do if Toro LX420 13AX60RG744 engine runs erratic?
- B
  bdavisAug 20, 2025
  If your Toro Lawn Mower engine is running erratically, consider the following: * Ensure the unit is not running with the CHOKE activated; move the Throttle/Choke Control out of the CHOKE position. * Check for loose spark plug wires and connect/tighten them. * Look for a blocked fuel line or stale fuel; clean the fuel line and fill the tank with fresh gasoline (less than 30 days old). * The vent in the gas cap may be plugged; clear the vent or replace the cap if damaged. * There might be water or dirt in the fuel system; drain the fuel tank. * A dirty air cleaner could be the problem; replace the air cleaner paper element or clean the foam precleaner.
