Blade Replacement Instructions for a Snapper Lawn Mower

Overview

To continue to cut your lawn properly with your Snapper lawn mower, it is important that you inspect your mower blades for signs of wear and damage. Damaged and worn blades can cause ripping or tearing of the grass blades, leaving your grass susceptible to some diseases. You should sharpen your blades during the mowing season once a month and replace the blades on your Snapper lawnmower at the first sign of wear.

Step 1

Drain the fuel from the fuel tank using a siphon hose and run the engine on the mower until it dies. Do not tip the lawnmower on its side to drain the tank as this could cause damage to the air filter and air intake system. Pull the spark plug wire off the spark plug located at the front of the engine.

Step 2

Tilt the mower up on its rear wheels and prop a piece of wood or a cinderblock beneath the mower to hold it in this position. Do not tilt the mower onto its side, with its spark plug or carburetor facing down as oil could drain into the air filter, causing the engine not to start.

Step 3

Remove the center bolt and the washer from the blade using an adjustable wrench. Turn the bolt clockwise to loosen and remove it. Lift the old blade off the blade hub that sits against the mower body and the mower drive belt beneath the mower.

Step 4

Install the replacement blade with the bent edges of the blade placed over the blade hub and facing the mower body. Replace the washer and center bolt, tightening counterclockwise with an adjustable wrench.

Step 5

Push the spark plug wire back on the spark plug and refill the fuel tank with fuel.
