How do you remove a lawn mower blade without removing the deck?
Removing a lawn mower blade without removing the deck is a relatively simple process. First, make sure the engine is off and cool. Next, prop the mower up on blocks or an incline so you can access and raise the blade from underneath.
Next, locate the crankshaft, which is typically found on the underside of the lawnmower, toward the front. This usually has a belt or other accessory connected to it. Unscrew the nut that holds it in place and keep the nut in a safe place.
Next, remove the blade balancer lever. This is located near the blade and helps keep it balanced while mowing. Loosen the wing nut and pull it out. Once the balancer lever is detached, take a flathead screwdriver and gently pry the lawn mower’s blade away from the center of the deck.
This may be more difficult to separate in some cases, so use caution not to damage the deck or cause any other damage. Finally, simply lift the blade off the deck. It is recommended to take the blade to a professional sharpener to get the blade sharpened and balanced.
