What to do if the clutch does not engage on my Toro Lawn Mower?
- A
  Angela MilesSep 7, 2025
  If the clutch does not engage on your Toro Lawn Mower, check for a low voltage supply at the clutch, inspecting the coil resistance, battery charge, charging system, and wiring connections, and replace parts if necessary. If the coil is damaged, replace the clutch. An inadequate current supply may also be the issue; repair or replace the clutch lead wire or electrical system and clean the connector contacts. If the rotor/armature air gap is too large, replace the clutch. Finally, a faulty blade control switch (PTO) can prevent clutch engagement, so replace it if necessary.

Why is my Toro Lawn Mower engine overheating?
- D
  Dillon CardenasSep 9, 2025
  If your Toro Lawn Mower's engine is overheating, several factors could be the cause. First, the engine load might be excessive, so try reducing the ground speed. Also, check the oil level in the crankcase and add oil if it's low. Obstructions in the cooling fins and air passages under the engine-blower housing can also cause overheating; remove any obstructions. A dirty air cleaner can contribute to this issue, so clean or replace the air-cleaner element. Finally, dirt, water, or stale fuel in the fuel system may be the culprit, in which case you should contact an Authorized Service Dealer.

Why is the malfunction indicator light on my Toro 77285 on?
- S
  spencerstewartSep 10, 2025
  If the malfunction-indicator light (MIL) comes on in your Toro Lawn Mower, it could be due to several reasons. The engine may be too hot; if so, shut it off and let it cool. Old fuel in the fuel tank can also trigger the light, so use new fuel. Ensure the fuel-shutoff valve is fully open. Check and clean the air cleaner and precleaner, replacing them if necessary. Charge or replace the battery if it's not charged. Also, ensure that you are using a good 12 V battery and that it is fully charged. Check and replace any blown fuses. For issues such as incorrect or dirty fuel filters, unsecured connections to the sensors electronic-control unit (ECU) and fuel injectors, contact an Authorized Service Dealer.

How to fix power loss in my Toro 77285 Lawn Mower engine?
- C
  Crystal CabreraSep 12, 2025
  If your Toro Lawn Mower engine loses power, first check if the engine load is excessive and reduce the ground speed. Next, inspect the air cleaner and clean the air-cleaner element if it's dirty. Also, verify the oil level in the crankcase and add 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 is plugged. Replace the fuel filter if it's dirty. For issues such as dirt, water, or stale fuel in the fuel system, contact an Authorized Service Dealer.
