Why won't my Toro Lawn Mower engine start?
- D
  Douglas PerryAug 15, 2025
  If your Toro Lawn Mower engine won't start, starts with difficulty, or stalls, several factors could be at play. First, make sure the fuel tank isn't empty and the fuel shutoff valve is open. Check the oil level in the crankcase and add oil if it's low. Ensure the throttle is midway between the “SLOW” and “FAST” positions, and the choke is “ON” for a cold engine or “OFF” for a warm one. Other potential causes include a dirty fuel filter (replace it), a dirty air cleaner (clean or replace it), a faulty spark plug (clean, adjust, or replace it), or a disconnected spark plug wire (check the connection). Also, verify the seat switch is functioning correctly, and the electrical connections are clean and secure.

What to do if my Toro Z Master 74141 starter does not crank?

  lellisAug 18, 2025
  If the starter on your Toro Lawn Mower doesn't crank, there are several things to check. First, ensure the blade control switch (PTO) is disengaged and the parking brake is set. The drive levers should be in the neutral lock position, and you must be seated. If these aren't the issue, check if the battery is dead and needs charging. Also, inspect the electrical connections for corrosion or looseness, and replace the fuse if it's blown.

Why is my Toro Z Master 74141 engine losing power?
- S
  Sabrina StantonAug 21, 2025
  If your Toro Lawn Mower engine is losing power, consider these potential causes: the engine load might be excessive, so reduce the ground speed. A dirty air cleaner can also cause power loss, so clean it. Check the oil level in the crankcase and add oil if needed. Make sure the cooling fins and air passages above the engine aren't blocked, and the vent hole in the fuel cap isn't plugged. Finally, a dirty fuel filter can restrict fuel flow, so replace it.

How to fix uneven cutting height on my Toro Z Master 74141 Lawn Mower?
- M
  Michele SmithAug 26, 2025
  To address uneven cutting height with your Toro Lawn Mower, consider these factors: the blades might not be sharp (sharpen them) or could be bent (install new ones). Also, the mower deck might not be level (level it from side-to-side and front-to-rear). Check if the underside of the mower is dirty (clean it) and ensure the tire pressure is correct (adjust it).

What to do if my Toro Z Master 74141 does not drive?
- K
  Kristen CollinsAug 27, 2025
  If your Toro Lawn Mower isn't driving, check that the by pass valves are closed tight. Inspect the pump belt for wear, looseness, or breakage, and change the belt if necessary. Also, make sure the pump belt is properly on the pulley. Look for a broken or missing idler spring and replace it if needed. Finally, verify that the hydraulic oil level is adequate and not too hot; add hydraulic oil or let it cool down.

- M
  Michael TaylorAug 30, 2025
  If your Toro Lawn Mower engine is overheating, here are a few things to investigate: First, check if the engine load is too high and reduce the ground speed. Also, ensure that the oil level in the crankcase is sufficient; add oil if it's low. Lastly, inspect the cooling fins and air passages above the engine for any blockages and remove them.

Why is my Toro Z Master 74141 Lawn Mower vibrating so much?
- M
  Michael OrtizSep 2, 2025
  If your Toro Lawn Mower is vibrating abnormally, check the following: * The cutting blades may be bent or unbalanced (install new blades). * The blade mounting bolt might be loose (tighten it). * The engine mounting bolts could be loose (tighten them). * A loose engine pulley, idler pulley, or blade pulley (tighten the appropriate pulley).

Why are the blades not rotating on my Toro Z Master 74141?
- J
  Jose YoungSep 5, 2025
  If the blades on your Toro Lawn Mower aren't rotating, check the mower deck belt for wear, looseness, or breakage, and install a new deck belt if needed. Also, ensure the mower deck belt is properly on the pulley, checking the idler pulley, idler arm, and spring for correct position and function. Inspect the pump drive belt for wear, looseness, or breakage, checking the belt tension or installing a new belt. Finally, look for a broken or missing idler spring and replace it.

Why does my Toro Z Master 74141 pull to one side?
- S
  sandra41Sep 8, 2025
  If your Toro Lawn Mower pulls to the left or right even with the levers fully forward, it could be due to tracking needing adjustment or incorrect tire pressure in the drive tires. Adjust the tracking and ensure the tire pressure in the drive tires is correct.
