  The engine may not start due to several reasons. The fuel tank could be empty, so fill it. The fuel-shutoff valve might be closed, so open it. The oil level in the crankcase could be low, so add oil. The throttle may not be in the correct position, so be sure that the throttle control is midway between the slow and fast positions. The fuel filter might be dirty, so replace it. The air cleaner might be dirty, so clean or replace the air-cleaner element. The seat switch may not be functioning properly, so check the seat-switch indicator and replace the seat if necessary. The electrical connections may be corroded, loose, or damaged, so check the electrical connections for good contact, clean the connector terminals thoroughly with electrical-contact cleaner, apply dielectric grease, and make...

  If your Toro Lawn Mower engine will not start, starts hard, or fails to keep running, fill the fuel tank, open the fuel shutoff valve and add oil to the crankcase. Ensure that the throttle control is midway between the “SLOW” and “FAST” positions. Also, replace the fuel filter, clean or replace the air cleaner element, check the seat switch indicator (replace the seat if needed), check the electrical connections for good contact (clean the connector terminals thoroughly with electrical contact cleaner, apply dielectric grease, and reconnect), clean, adjust, or replace the spark plug and check the spark plug wire connection. If problems persist, contact an Authorized Service Dealer.

Why Toro 72946 blades do not rotate?
- C
  Chase AllenAug 27, 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; in this case, install a new deck belt. Another possibility is that the mower deck belt is off the pulley; reinstall it and check the idler pulley, idler arm, and spring for correct position and function. Also, check the pump drive belt for wear, looseness, or breakage, and adjust the belt tension or install a new belt. Finally, inspect the idler spring and replace it if it's broken or missing.

What causes my Toro 72946 Lawn Mower engine to lose power?
- C
  Christopher GomezSep 3, 2025
  A loss of power in your Toro Lawn Mower engine can stem from several causes. The engine load might be excessive, so reduce the ground speed. Check the air cleaner element; if it's dirty, clean it. Ensure the oil level in the crankcase is sufficient by adding oil if needed. Clear any obstructions from the cooling fins and air passages above the engine, and clean or replace the fuel cap if the vent hole is plugged. Also, replace the fuel filter if it's dirty. For issues like dirt, water, or stale fuel in the fuel system, contact an Authorized Service Dealer.

What should I do if the oil-pressure light is on and the engine rpm is low on my Toro 72946?
- N
  Nathan SharpSep 18, 2025
  If the oil-pressure light is on and the engine rpm is low on your Toro Lawn Mower, it means the engine-control unit has limited engine rpm, known as “limp” mode. Let the engine cool and check the engine-oil level. If the level is above the “add” line, contact an Authorized Toro Service Dealer.

  Robert NguyenSep 15, 2025
  If your Toro lawn mower isn't driving, check if the by pass valves are not closed tight and tighten them. Also, inspect the pump belt for wear, looseness, or breakage and change the belt if needed. Ensure the pump belt is on a pulley. Replace any broken or missing idler spring. Lastly, check the hydraulic oil level and add hydraulic oil to reservoirs or let it cool down if it's too hot.
