Why Toro TIMECUTTER 75740 Lawn Mower engine does not start?
- M
  Megan NealAug 16, 2025
  Several factors can cause your Toro Lawn Mower engine to not start, start hard, or fail to keep running. These include an empty fuel tank (fill the fuel tank), incorrect throttle position (ensure the throttle control is in the fast position), a dirty fuel filter (replace the fuel filter), dirt, water, or stale fuel in the fuel system (clean and flush the fuel system), a dirty air cleaner (clean or replace the air cleaner element), or a malfunctioning seat switch (check and replace if faulty). Additionally, check for corroded, loose, or damaged electrical connections (clean and apply dielectric grease), a fouled or improperly gapped spark plug (adjust or replace the spark plug), a disconnected spark plug wire (check the connection), or a worn or damaged switch (test and replace).

What to do if my Toro TIMECUTTER 75740 Lawn Mower starter does not crank?

  sduncanAug 31, 2025
  If the starter on your Toro Lawn Mower doesn't crank, it could be due to several reasons: the blade control switch (PTO) is engaged (move it to the disengaged position), the parking brake isn't engaged (move the motion control levers to the neutral lock/park position), the battery is dead (charge the battery), the electrical connections are corroded or loose (check for good contact), a switch is worn or damaged (test and replace), or the fuse is blown (replace the fuse).

Why Toro TIMECUTTER 75740 pulls to the left or right?

  Lori AlexanderSep 9, 2025
  If your Toro Lawn Mower pulls to the left or right (with levers fully forward), the tracking may need adjustment, the smart speed shift forks may not be correctly aligned on the motion control linkage (realign and install), or the tire pressure in the drive tires may be incorrect (adjust the tire pressure).
