Why won't my Toro ProLine Hydro engine start?
- K
  Kim HensleyAug 17, 2025
  There are several reasons why your Toro Lawn Mower engine might not start: * The fuel tank may be empty, so fill it with gasoline. * The PTO might be on (pulled up), so turn the PTO off (push it in). * The speed control lever may be in gear, so move it to neutral. * The choke might not be on, so move the choke lever to the ON position. * The air cleaner might be dirty, so clean or replace the air cleaner element. * The spark plug wire may be loose or disconnected, so install the wire on the spark plug. * The spark plug may be pitted, fouled, or have an incorrect gap, so install a new, correctly gapped spark plug. * There might be dirt in the fuel filter, so replace the fuel filter.
