How to Change the Blade on Kohler Courage XT7 Mower
- 1). Make sure the Kohler engine is off. Detach the spark plug wire to ensure that all power is removed from the engine's components.
- 2). Place a wood block against the blade. Confirm that the blade cannot move or rotate with the block in place.
- 3). Detach and remove the bolt holding the blade to the Kohler engine's shaft with a wrench. Carefully slide the lock and flat washers from the blade as well. Detach and remove the blade.
- 4). Place a new blade on the engine's shaft. Slide a flat washer and lock washer onto the shaft.
- 5). Place a bolt onto the shaft. Tighten the bolt to a maximum of 50 foot-pounds with a torque wrench. Visually verify that the lock washer is flush between the bolt and flat washer.
- 6). Remove the wood block. Reattach the spark plug wire. Turn the engine back on, then test the lawnmower's cutting action.
