Steps to Change the Blade on a Zero Turn Mower?

Step 1: Disconnect Spark Plug

Before beginning, we should always ensure that the spark plug is disconnected so that the mower does not have access to the current.

This is the most important safety measure that should always be followed whenever you are trying to fix something in your mower.

Most of the mowers have their spark plugs located anywhere near the engine. Still, if you do not find the spark plug, read the user’s manual.

Step 2: Remove the Blade Belt

After disconnecting the mower from the current, you have to push the mower deck to its lowest position.

Further, on the left side of the deck, you will notice a pulley cover, remove that.

Once you uncover the left side of the blade you will notice a blade belt, remove that too by rolling it on.

Step 3: Remove the Mower Deck

After the removal of the blade belt, you have to remove the mower deck as well.

For doing so, you have to remove the mounting pins and the brackets that are supporting the deck for attaching used to the mower.

Once the brackets and pins are attached, push the mower deck from its back so that it can be easily pulled off.

Step 4: Remove Blades from Deck

Here comes the trickiest part of the story, that is the removal of the blade from the mower deck.

Remember, always wear gloves and never try to do it in a hurry else you might hurt yourself.

Once you have taken out the mower deck from your zero turn mower, turn it upside down in order to have access to the cutting blade.

You will notice a mounting bolt that is inserted to attach the blade with the deck, remove that.

Once the mounting bolt is removed, pull the blade off from the deck.

Step 5: Attach new blades into the Mower Deck

Take out your new replacement blade and before attaching it to the deck, ensure it is of proper size.

Fit it into the mower deck and put the mounting bolt on to it.

The mounting bolt should be tightened properly with a torque wrench or else the blade may fall apart.

Step 6: Attach Mower Deck to its original Position

Once the new blade is installed in the mower deck, it’s time to put the deck back on its position.

Fit the mower deck accurately on the mower frame and fix it with the hanging brackets properly.

Do not forget to put the mounting pins back on to the mower deck once you attach the deck to the frame.

Step 7: Finishing it up

Take your eyes on the blade belt that you removed initially. Reattach with the pulley and secure it with the pulley cover.

Connect the spark plug again and you are done!
