Why won't my Toro 74915 starter crank?
- W
  wgibsonAug 28, 2025
  If the starter on your Toro Lawn Mower doesn't crank, there are several possible reasons. First, ensure the blade control switch (PTO) is disengaged and the parking brake is set. Also, make sure the drive levers are in the neutral lock position and that you are seated on the seat. If these aren't the problem, check if the battery is dead and charge it if necessary. Inspect the electrical connections for corrosion or looseness, and replace the fuse if it's blown.

  Rebecca FieldsAug 28, 2025
  If your Toro Lawn Mower engine won't start, starts hard, or fails to keep running, several factors could be at play. First, ensure the fuel tank isn't empty and the fuel shutoff valve is open. Check that the oil level in the crankcase is adequate. For a cold engine, make sure the throttle control is midway between the “SLOW” and “FAST” positions, and the choke is in the “ON” position; for a warm engine, the choke should be “OFF”. Also, inspect the fuel filter for dirt and clean or replace the air cleaner element if it's dirty. Check the seat switch indicator and replace the seat if needed. Inspect all electrical connections, clean connector terminals, apply dielectric grease, and reconnect. Clean, adjust or replace the spark plug and check the spark plug wire connection.

What to do if Toro 74915 Lawn Mower blades do not rotate?
- M
  mckeejacobAug 26, 2025
  If the blades on your Toro Lawn Mower aren't rotating, it could be due to a worn, loose, or broken mower-deck belt; install a new deck belt. The mower-deck belt might also be off the pulley; install the mower-deck pulley and check the idler pulley, idler arm, and spring for correct position and function. Additionally, check the pump-drive belt for wear, looseness, or breakage and check the belt tension or install a new belt. A broken or missing idler spring can also cause this issue; replace the spring.

Why is the cutting height uneven on my Toro 74915?
- M
  Miguel WalkerAug 26, 2025
  Uneven cutting height on your Toro Lawn Mower can stem from several issues. Start by sharpening the blades. If a cutting blade is bent, install a new one. Ensure the mower is level from side-to-side and front-to-rear. If applicable, check that the anti-scalp roller is set correctly and clean the underside of the mower deck. Finally, verify that the tire pressure is correct.

How to fix a Toro 74915 engine that loses power?
- J
  jeffreywallAug 26, 2025
  If your Toro Lawn Mower engine is losing power, it could be due to several reasons. First, check if the engine load is excessive and reduce the ground speed. A dirty air cleaner can also cause power loss, so clean the air-cleaner element. Ensure that the oil level in the crankcase is adequate, adding oil if necessary. Additionally, inspect the cooling fins and air passages above the engine for any obstructions and remove them. Lastly, the vent hole in the fuel cap may be plugged, so clean or replace the fuel cap.

  If your Toro Lawn Mower engine doesn't start, starts hard, or fails to keep running, several factors could be at play. First, ensure the fuel tank isn't empty and the fuel-shutoff valve is open.
