How to Change a Riding Lawn Mower Belt

Overview

The engine of the riding lawnmower not only runs the blades of the machine, but it also propels the machine forward. A drive belt that runs along the bottom of the machine powers the blades as the mower moves along. This belt is attached to a pulley at the front of the machine, which is attached to the mower engine, which engages a set of pulleys over the blade. This belt spins the blades using the power of the engine.

Step 1

Place the mower on a level surface, engage the parking brake, take the key out and remove the spark plug wire from the spark plug. This prevents any accidents.

Step 2

Look for the sticker that indicates the drive belt routing for your mower. Study it before removing the belt.

Step 3

Unscrew the bolts for the pulley guard and place them to the side. Remove the pulley guard by lifting up and away from the pulley system.

Step 4

Remove the belt from the engine pulley area first to loosen the belt along the system and pull the belt out of the pulley guides. Remove the belt from the rest of the pulley system.

Step 5

Install a new belt by putting it first around the back pulleys according to the routing guide, making sure the belt is installed between the pulley guide and the pulley wheel. Install the belt at the engine pulley. Test the belt by turning on the engine.
