Why does my Toro Riding mower have abnormal vibration?
- K
  Kevin JimenezSep 12, 2025
  Abnormal vibration in your Toro Riding mower can be caused by several factors. The cutting blades might be bent or unbalanced, so install new cutting blades. Check if the blade mounting bolt or engine mounting bolts are loose and tighten them. Also, inspect for loose engine pulley, idler pulley, or blade pulley and tighten the appropriate pulley. For a damaged engine pulley, bent blade spindle, or loose/worn motor mount, contact an Authorized Service Dealer.

Why won't my Toro Z453 Z Master Lawn Mower engine start?

  imoralesAug 22, 2025
  If your Toro Lawn Mower's engine won't start, starts hard, or fails to keep running, several factors could be at play. First, ensure the fuel tank is filled with gasoline and the fuel valve is open. Next, make sure the choke is on. Check if the air cleaner is dirty and clean or replace it if necessary. Also, verify that the spark plug wires are securely connected to the spark plugs and that the spark plugs are new and correctly gapped. Finally, inspect the fuel filter for dirt and replace if needed. If the issue persists, it could be due to dirt, water, or stale fuel in the fuel system, in which case you should contact an Authorized Service Dealer.

Why does my Toro Riding mower have an uneven cutting height?
- C
  charles64Aug 28, 2025
  Uneven cutting height on your Toro Riding mower could be due to several reasons. The blades may not be sharp, so sharpen them. Bent cutting blades should be replaced with new ones. Ensure the mower is level from side-to-side and front-to-rear. Clean the underside of the mower if it's dirty, and adjust the tire pressure if it's incorrect. For a bent blade spindle, contact an Authorized Service Dealer.

  If the blades on your Toro Riding mower do not rotate, check the drive belt tension, install the drive belt and check adjusting shafts and belt guides for correct position if the drive belt is worn, loose, or broken, or off the pulley. Install a new deck belt if the deck belt is worn, loose, or broken. Install the deck pulley and check the idler pulley, idler arm and spring for correct position and function if the deck belt is off the pulley. Replace the spring if the idler spring is broken or missing.

  If the starter on your Toro Lawn Mower isn't cranking, there are several things you can check. First, ensure that the blade control (PTO) is disengaged and the parking brake is set. Also, make sure you are seated on the seat. Check the battery to ensure it is charged. Inspect the electrical connections for any corrosion or looseness, ensuring good contact.
