Why won't my Toro 74226 Lawn Mower starter crank?
- T
  Todd WilliamsAug 13, 2025
  Your Toro Lawn Mower's starter might not crank due to several reasons: the blade control (PTO) may be engaged (disengage it); the parking brake might not be on (set it); you may not be seated (sit on the seat); the battery could be dead (charge it); electrical connections might be corroded or loose (check them); or a fuse could be blown (replace it). If none of these solve the issue, a relay or switch may be defective.

What to do if my Toro Lawn Mower engine won't start or keeps stalling?

  Brian ArnoldAug 17, 2025
  If your Toro Lawn Mower engine won't start, starts hard, or stalls, check these potential causes: the fuel tank could be empty (fill it with gasoline); the choke may not be on (move the choke lever to the on position); the air cleaner might be dirty (clean or replace the air cleaner element); spark plug wires could be loose (install the wires on the spark plug); the spark plugs may be faulty (install new, correctly gapped spark plugs); or the fuel filter could be dirty (replace the fuel filter). If these steps don't resolve the issue, the fuel system may have dirt, water, or stale fuel.

  Your Toro Lawn Mower engine might lose power for several reasons: the engine load could be excessive (reduce ground speed); the air cleaner may be dirty (clean the air cleaner element); the oil level in the crankcase might be low (add oil); cooling fins and air passages under the engine blower housing could be plugged (remove any obstructions); the spark plugs may be pitted or have an incorrect gap (install new, correctly gapped spark plugs); the vent in the fuel cap might be closed (open the vent); or the fuel filter could be dirty (replace the fuel filter).

Why does my Toro Lawn Mower have an uneven cutting height?

  millerannetteAug 25, 2025
  An uneven cutting height with your Toro Lawn Mower may be due to: blade(s) not being sharp (sharpen them); cutting blade(s) being bent (install new ones); the mower not being level (level it from side-to-side and front-to-rear); the gage wheel not set correctly (adjust the gage wheel height); the underside of the mower being dirty (clean it); or incorrect tire pressure (adjust it).

  To prevent your Toro Lawn Mower engine from overheating, consider these factors: the engine load might be excessive (reduce ground speed); the oil level in the crankcase could be low (add oil to the crankcase); or the cooling fins and air passages under the engine blower housing may be plugged (remove any obstructions).

Why is my Toro Lawn Mower vibrating abnormally?
- A
  Autumn FreemanSep 4, 2025
  Abnormal vibration in your Toro Lawn Mower can stem from: bent or unbalanced cutting blade(s) (install new cutting blade(s)); a loose blade mounting bolt (tighten it); loose engine mounting bolts (tighten them); or a loose engine pulley, idler pulley, or blade pulley (tighten the appropriate pulley). If the engine pulley is damaged or the blade spindle is bent, it could also cause vibration.

What to do if the blades on my Toro Lawn Mower do not rotate?
- D
  Darlene MurraySep 9, 2025
  If the blades on your Toro Lawn Mower aren't rotating, it could be due to: a worn, loose, or broken drive belt (install a new one); the drive belt being off the pulley (install the drive belt and check the adjusting shafts and belt guides for correct position); a worn, loose, or broken deck belt (install a new one); or the deck belt being off the pulley (install the deck pulley and check the idler pulley, idler arm, and spring for correct position and function).
