To remove the lawn mower blade, first shut off the power and disconnect the spark plug wire. Then turn the mower on its side so you can access to underside of it. Unscrew the bolts that hold the blade in place using a wrench or socket set.

Once all bolts are removed, carefully take out the blade from underneath of your mower deck and be sure to keep track of any washers or spacers that may have been attached to it. Clean up any debris around where blades were mounted and then proceed to reinstall new blades correctly by following manufacturer’s instructions for your particular model.

  • Step 1: Unplug the Lawn Mower from Power Source: Before you start any work on a lawn mower, make sure it is unplugged from the power source. This will help prevent injury or damage to your equipment.
  • Step 2: Remove Bolts and Washers Holding Blade in Place: The blade should be held in place by at least three bolts and washers. Use a socket wrench to loosen and remove these bolts carefully, taking care not to drop them into the grass or soil below.
  • Step 3: Carefully Slide Out Old Blade: Once all of the hardware has been removed, gently slide out the old blade away from the machine so that it does not cause any further damage. It may be helpful to use gloves when handling this part as there may still be sharp edges present on its surface.
  • Step 4: Clean Off Blade Mounting Surface : Take a wire brush and clean off any debris that has accumulated on top of mounting surface for new blades before installing one onto it; this will ensure proper contact between blade and engine shaft which can increase performance significantly over time if done properly.
