How to fix a Toro 74480 that won't crank?
- J
  Jennifer MosesAug 22, 2025
  If your Toro Lawn Mower starter does not crank, first ensure that the blade-control switch is disengaged. Next, make sure the motion-control levers are in the NEUTRAL-LOCK position by moving them outward. If it still doesn't crank, the battery may be dead and needs charging. Check the electrical connections for corrosion or looseness, ensuring they have good contact. Also, inspect the fuse and replace it if it's blown. If the problem continues, there may be damage to a relay or switch, in which case you should contact an Authorized Service Dealer.

Why does my Toro 74480 engine lose power?
- E
  Erin WardAug 26, 2025
  If your Toro Lawn Mower engine loses power, try these steps: First, reduce the ground speed, as the engine load may be excessive. Second, check the air cleaner and clean the air-cleaner element if it's dirty. Third, ensure the oil level in the crankcase is adequate by adding oil if it's low. Clear any obstructions from the cooling fins and air passages above the engine. Clean or replace the fuel cap if the vent hole in it is plugged. Replace the fuel filter if it's dirty. If the problem persists, it is recommended to contact an Authorized Service Dealer because there may be dirt, water, or stale fuel in the fuel system.

Why is the cutting height uneven on my Toro Lawn Mower?
- K
  Kevin MullinsAug 28, 2025
  If the cutting height of your Toro Lawn Mower is uneven, make sure that the blade(s) is sharp or install a new cutting blade(s) if a cutting blade(s) is/are bent. Level the mower from side-to-side and front-to-rear. Adjust the anti-scalp wheel height, if applicable. Clean the underside of the mower deck. Adjust the tire pressure. If a blade spindle is bent, it is recommended to contact an Authorized Service Dealer.

Why is my Toro 74480 engine overheating?
- K
  kimberlyhartmanAug 30, 2025
  If your Toro Lawn Mower engine is overheating, several factors could be the cause. First, the engine load might be too high, so try reducing the ground speed. Second, check the oil level in the crankcase and add oil if it's low. Third, inspect the cooling fins and air passages under the engine-blower housing for any obstructions and remove them. Also, the air cleaner might be dirty, so clean or replace the air-cleaner element. If the issue persists, there might be dirt, water, or stale fuel in the fuel system, in which case you should contact an Authorized Service Dealer.

Why is my Toro 74480 Lawn Mower vibrating so much?
- D
  David CostaAug 31, 2025
  If your Toro Lawn Mower is vibrating abnormally, it could be due to several reasons. Check if the cutting blade(s) is/are bent or unbalanced and install new cutting blade(s). Ensure the blade mounting bolt and the engine mounting bolts are tightened. Also, check the engine pulley, idler pulley, or blade pulley for looseness and tighten the appropriate pulley. If the engine pulley is damaged or the blade spindle is bent, or the motor mount is loose or worn, it is recommended to contact an Authorized Service Dealer.

Why does my Toro 74480 pull to one side?
- B
  Bryan MunozSep 2, 2025
  If your Toro Lawn Mower pulls to the left or right when the levers are fully forward, it could be due to the tracking needing adjustment or incorrect tire pressure in the drive tires. Adjust the tracking and adjust the tire pressure in the drive tires.

What to do if my Toro Lawn Mower won't drive?
- T
  Tamara LarsonSep 4, 2025
  If your Toro Lawn Mower does not drive, ensure the bypass valves are closed tight by tightening them. If that doesn't solve the problem, the pump belt may be worn, loose, or broken, or off a pulley, in which case you should change the belt. Also, the idler spring may be broken or missing, so replace the spring. Finally, check the hydraulic fluid level; if it's low, add hydraulic fluid to the reservoirs, or if it's too hot, let it cool down.

Why aren't the blades rotating on my Toro 74480 Lawn Mower?
- M
  Melinda AguilarSep 6, 2025
  If the blades on your Toro Lawn Mower do not rotate, it could be caused by a worn, loose, or broken drive belt, so install a new drive belt. Also, the drive belt may be off of the pulley, so install the drive belt and check the adjusting shafts and belt guides for the correct position. The mower belt may be worn, loose, or broken, so install a new mower belt. If the power takeoff (PTO) switch or PTO clutch is faulty, it is recommended to contact an Authorized Service Dealer.

What causes the clutch not to engage on my Toro 74480 Lawn Mower?
- C
  Crystal OdonnellSep 8, 2025
  If the clutch on your Toro Lawn Mower does not engage, first replace the fuse, as it may be blown. If that doesn't work, check the coil resistance, battery charge, charging system, and wiring connections for low voltage supply at the clutch, and replace components if necessary. If the coil is damaged, replace the clutch. If there is inadequate current supply, repair or replace the clutch lead wire or electrical system and clean the connector contacts. If the rotor/armature air gap is too large, remove the shim or replace the clutch.

  Mark GreenSep 10, 2025
  If your Toro Lawn Mower starter doesn't crank, first ensure the blade-control switch is disengaged. Next, make sure the motion-control levers are in the NEUTRAL-LOCK position. If it still doesn't crank, the battery might be dead, so charge it. Check the electrical connections for good contact if they are corroded or loose. Also, inspect the fuse and replace it if it's blown. If none of these steps work, a relay or switch might be damaged, and you should contact an Authorized Service Dealer.
