  Kyle KaneAug 14, 2025
  If the starter on your Toro Lawn Mower isn't cranking, there are several potential causes. First, make sure the blade control (PTO) is disengaged. Next, ensure the parking brake is set and that you are seated on the seat. If these aren't the issue, check the battery; it may be dead and need charging. Also, inspect the electrical connections for corrosion or looseness, and replace the fuse if it's blown. If none of these steps work, the relay or switch may be defective, and you should contact an Authorized Service Dealer.

  If your Toro Lawn Mower engine is losing power, there are several things to check. First, reduce your ground speed, as the engine load may be excessive. Also, clean the air cleaner element, as a dirty air cleaner can cause power loss. Make sure that the oil level in the crankcase is adequate by adding oil if it is low. Clear any obstructions from the cooling fins and air passages above the engine. Clean or replace the fuel cap to ensure the vent hole isn't plugged. Finally, replace the fuel filter if it is dirty. If these steps don't resolve the issue, there may be dirt, water, or stale fuel in the fuel system, and you should contact an Authorized Service Dealer.

  If your Toro Lawn Mower has an uneven cutting height, several factors could be the cause. Start by sharpening the cutting blades if they are not sharp. If the cutting blades are bent, install new ones. Ensure the mower deck is level from side-to-side and front-to-rear. Clean the underside of the mower if it's dirty. Adjust the tire pressure to the correct level. If the blade spindle is bent, contact an Authorized Service Dealer.

  If the cutting blades on your Toro Lawn Mower do not rotate, there are several potential causes to investigate. Start by checking the drive belt for wear, looseness, or breakage and check the belt tension. If the drive belt is off the pulley, install the drive belt and check adjusting shafts and belt guides for correct position. Check the mower deck belt for wear, looseness, or breakage and install a new mower deck belt if needed. If the mower deck belt came off a pulley, install the mower deck belt and check the idler pulley, idler arm and spring for the correct position and function. Finally, replace the idler spring if it is broken or missing.
