Procedure for Replacing Mower Blades on a Lawn Tractor

The lawn tractor shown in this guide is a Simplicity Broadmoor 16hp (package 2690008).


The first step is to turn the key to the ‘off’ position. Disconnect the negative battery terminal.

I like to jack up the mower and secure it with some jackstands. Otherwise use ramps. Set the parking brake on the mower.


Peer under the mower deck at the blades.


We will need to remove the cap screw. This requires a 5/8″ wrench or socket.


Use a block of wood to secure the blade against the side of the mower deck. Turn the capscrew counter-clockwise to loosen it (as shown in the manual).


Once the bolt is loose, remove it along with the washers.


These are the parts you have removed.


Sharpen the blades or replace them. These are the blades I recommend:

Replacement Mower Blades (44″ deck)

To re-install the blades, put a block of wood again against the deck to prevent the blade from turning. Install the spring washer, hex washer, and blade bolt.

Note: blades should be installed with the tabs (airlifts) turned up, toward the mower deck.


Use a torque wrench to tighten the blade bolt to 45-55 ft. lbs.
