Why does my Toro 74765 engine not start, start hard, or fail to keep running?
- D
  Danny McbrideAug 21, 2025
  Your Toro Lawn Mower may not start, start hard, or keep running for several reasons. The fuel tank could be empty, so fill it. The choke might not be on, so move the choke lever to the On position. The air cleaner could be dirty; therefore, clean or replace the air cleaner element. The spark plug wire(s) may be loose or disconnected, so install the wire(s) on the spark plug. The spark plug(s) may be pitted, fouled, or have an incorrect gap, so install a new, correctly gapped spark plug(s). There may be dirt in the fuel filter, so replace it. There may be incorrect fuel in the fuel tank, so drain the tank and replace the fuel with the proper type. The oil level in the crankcase could be low, so add oil to the crankcase.

Why is my Toro 74765 Lawn Mower cutting height uneven?
- M
  malonestacyAug 27, 2025
  An uneven cutting height on your Toro Lawn Mower can be due to several reasons. The blade(s) may not be sharp, so sharpen the blade(s). A cutting blade(s) may be bent, so install a new cutting blade(s). The mower might not be level, so level the mower from side-to-side and front-to-rear. An anti-scalp wheel may not be set correctly, so adjust the anti-scalp wheel height. The underside of the mower could be dirty, so clean it. Finally, the tire pressure might be incorrect, so adjust the tire pressure.

  If your Toro Lawn Mower engine is overheating, several factors could be the cause. First, the engine load might be excessive, so reduce the ground speed.

Why is my Toro Lawn Mower engine losing power?
- B
  Brenda BurnsSep 5, 2025
  A loss of power in your Toro Lawn Mower engine can stem from several causes: excessive engine load, which can be resolved by reducing ground speed; a dirty air cleaner, which requires cleaning; or a low oil level in the crankcase, necessitating the addition of oil. Furthermore, check for obstructions in the cooling fins and air passages under the engine blower housing and remove them if present. Ensure the spark plug(s) is in good condition; if pitted, fouled, or incorrectly gapped, replace it. Check the fuel filter for dirt and replace if necessary. Finally, if you are using incorrect fuel, drain the tank and replace it with the proper type.
