How to fix a Rally Lawn Mower that will not start?
- N
  Nicholas ChavezAug 20, 2025
  If your Rally Lawn Mower won't start, several factors could be the cause. Ensure the fuel tank is full. If the engine is flooded, wait a few minutes before trying again. A bad spark plug, dirty air filter, or dirty fuel filter can also prevent starting, so replace them if necessary. Water in the fuel can also be a culprit; in this case, empty the fuel tank and carburetor, refill with fresh gasoline, and replace the fuel filter. Also, check all wiring for any loose or damaged connections. If the engine is not choked properly, refer to the “TO START ENGINE” section in the Operation section. For carburetor or engine valve adjustments, it is best to seek assistance from an authorized service center/department.

How to improve grass discharge on my Rally Lawn Mower?
- J
  John WhitakerAug 28, 2025
  If your Rally Lawn Mower has poor grass discharge, ensure the engine speed is set to “FAST” and that you're not traveling too fast; shift to a slower speed if necessary. Avoid mowing wet grass, and make sure the mower deck is level. Check and correct tire air pressure if it's low or uneven. Replace the blade if it is worn, bent or loose blade. Clean the underside of the mower housing to remove any buildup of grass, leaves, and trash. Replace the mower drive belt if it's worn. Ensure blades are properly installed with the sharp edge down, and that you are using the correct blades as listed in the parts manual. Finally, clean around the mandrels to open vent holes if they are clogged with grass, leaves, and trash.
