Why Toro Riding mower blades do not rotate?
- B
  Brett OliverSep 7, 2025
  If the blades on your Toro Riding mower do not rotate, install a new drive belt if the current one is worn, loose, or broken. If the drive belt is off of the pulley, reinstall it and check the adjusting shafts and belt guides for the correct position. If the mower belt is worn, loose, or broken, install a new mower belt. Also, ensure the collection bag is properly installed, seated flush with the machine frame, and the presence switch is engaged.

Why won't my Toro 74433 Lawn Mower engine start?
- C
  Colleen SharpAug 22, 2025
  Your Toro Lawn Mower might not start due to several reasons. The fuel tank could be empty, so fill it up. The fuel valve may be turned off, so open it. The choke might not be on, so move the choke lever to the On position. The air filter could be dirty, so clean or replace it. A spark plug wire could be loose, so install it correctly. The spark plug itself might be bad, so replace it with a new, correctly gapped one. There might be dirt in the fuel filter, so replace the filter. Also, the fuel could be stale or the wrong type, or the oil level may be low, so address those issues accordingly.

  Sarah JohnsonSep 4, 2025
  If your Toro Riding mower is producing an uneven cutting height, several factors could be the cause. Start by sharpening the blade(s), and replace any cutting blade(s) if they are bent. Ensure the mower is level from side-to-side and front-to-rear, and adjust the anti-scalp wheel height if it's not set correctly. Clean the underside of the mower if it's dirty, and adjust the tire pressure if it's incorrect. If a blade spindle is bent, contact an Authorized Service Dealer.

- C
  Charles BrownSep 3, 2025
  If your Toro Riding mower engine loses power, there are several potential causes. First, reduce ground speed if the engine load is excessive. Clean the air cleaner element if it's dirty, and add oil to the crankcase if the oil level is low. Clear any obstructions from the cooling fins and air passages. Replace the spark plug(s) if it's pitted, fouled, or the gap is incorrect. Open the vent in the fuel cap if it's closed, and replace the fuel filter if it's dirty. If the fuel system contains dirt, water, or stale fuel, or if there is incorrect fuel in the fuel tank, contact an Authorized Service Dealer.
