Why aren't the blades rotating on my Toro Lawn Mower?
- S
  Stephanie RoachSep 10, 2025
  If the blades on your Toro Lawn Mower aren't rotating, it could be due to a worn, loose, or broken mower deck belt (install new deck belt). Another cause might be that the mower deck belt is off the pulley (install mower deck pulley and check the idler pulley, idler arm and spring for correct position and function). Also, check for a worn, loose, or broken pump drive belt (check the belt tension or install new belt) or a broken/missing idler spring (replace the spring).

Why Toro Lawn Mower engine will not start?
- K
  Kathryn LewisAug 23, 2025
  There are several reasons why your Toro Lawn Mower engine might not start. It could be due to an empty fuel tank, a closed fuel shutoff valve, or a low oil level in the crankcase. The throttle and choke may not be in the correct position. Other potential causes include a dirty fuel filter, dirt, water, or stale fuel in the fuel system, a dirty air cleaner, or a faulty spark plug. Also, check the spark plug wire connection and the seat switch indicator. Clean connector terminals thoroughly with electrical contact cleaner, apply dielectric grease and reconnect if electrical connections are corroded, loose or faulty.

Why Toro TITAN MX4880 cutting height is uneven?
- P
  Patrick BrownAug 25, 2025
  Uneven cutting height on your Toro Lawn Mower can be attributed to several factors. The blades might not be sharp or could be bent. The mower deck may not be level from side-to-side and front-to-rear. Also, check if the underside of the mower is dirty and clean it if necessary. Finally, ensure the tire pressure is correct and adjust if needed.

  If the starter on your Toro Lawn Mower doesn't crank, make sure the blade control switch (PTO) is disengaged, the parking brake is set, and the drive levers are in the neutral lock position. Also, ensure you are seated. Other possible causes include a dead battery, corroded or loose electrical connections, or a blown fuse. In case of a defective relay or switch, contact an Authorized Service Dealer.

How to fix a Toro TITAN MX4880 Lawn Mower engine that loses power?

  Maurice LewisAug 27, 2025
  If your Toro Lawn Mower engine loses power, it could be due to an excessive engine load, so reduce the ground speed. Other causes may include a dirty air cleaner, low oil level in the crankcase (add oil to the crankcase), plugged cooling fins and air passages (remove the obstruction), a plugged vent hole in the fuel cap (clean or replace the fuel cap), or a dirty fuel filter (replace the fuel filter). For dirt, water, or stale fuel in the fuel system, contact an Authorized Service Dealer.

  Your Toro Lawn Mower engine might be overheating due to an excessive engine load, so reduce the ground speed. It could also be caused by a low oil level in the crankcase, so add oil.
