Why is my Toro Lawn Mower cutting height uneven?
- C
  Christine GonzalezAug 18, 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.

Why is my Toro 74731 Lawn Mower engine losing power?

  gloriagonzalezAug 22, 2025
  If your Toro Lawn Mower engine is losing power, it could be due to several reasons: * The engine load may be excessive, so reduce ground speed. * The air cleaner may be dirty, so clean it. * The oil level in the crankcase may be low, so add oil. * The cooling fins and air passages under the engine blower housing may be plugged, so remove the obstruction. * The spark plug(s) may be pitted, fouled, or the gap may be incorrect, so install a new, correctly gapped spark plug(s). * There may be dirt in the fuel filter, so replace the fuel filter. * There may be incorrect fuel in the fuel tank, so drain the tank and replace the fuel with the proper type.
