    Why aren't the blades rotating on my Toro 74871?
    • D
      Danielle MortonSep 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 74871 engine will not start?
    • K
      Kevin TrujilloAug 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 Lawn Mower cutting height is uneven?
    • E
      Earl KennedyAug 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.

      Cory McclainAug 27, 2025
      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 74871 Lawn Mower engine that loses power?
    • L
      lindarussellAug 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.

    What causes uneven cutting height on my Toro 74871 Lawn Mower?
    • J
      Jennifer RodgersAug 29, 2025
      Uneven cutting height on your Toro Lawn Mower may result from dull blade(s) (sharpen the blade(s)), bent cutting blade(s) (install new cutting blade(s)), or a mower deck that is not level (level mower deck from side-to-side and front-to-rear). Other causes include a dirty mower underside (clean the underside) or incorrect tire pressure (adjust the tire pressure). For a bent blade spindle, contact an Authorized Service Dealer.

      If your Toro Lawn Mower pulls to the left or right even when the levers are fully forward, it could be due to tracking needing adjustment, so adjust the tracking. Also, check the tire pressure in the drive tires and adjust as necessary.

      justinperezSep 8, 2025
      If your Toro Lawn Mower doesn't drive, check if the by pass valves are not closed tight and tighten them. Other possible causes include a worn, loose, or broken pump belt (change the belt), a pump belt that is off a pulley (change the belt), a broken or missing idler spring (replace the spring), or a low/too hot hydraulic oil level (add hydraulic oil to reservoirs or let it cool down).

    Why is my Toro 74871 Lawn Mower engine overheating?
    • B
      Brittany Estrada MDSep 5, 2025
      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. Another possible reason is that the cooling fins and air passages above the engine are plugged; remove any obstructions.
