Step 1: Prepare the mower
– Park the mower on a flat, stable surface and turn off the engine.

Step 2: Locate the drive belt
– Open the hood of the mower to access the engine.
– Look for the drive belt, which is typically located between the engine and the mower deck.
– The drive belt may be covered by a guard or shield, so you may need to remove it to access the belt.
Step 3: Remove the old drive belt

Step 4: Install the new drive belt
– Place the new drive belt around the pulleys, ensuring it is properly aligned.
– Re-tighten the tensioner pulley to apply tension to the new belt.
– Double-check the belt’s alignment and make sure it is not twisted or misaligned.
Step 5: Reinstall the belt guard or shield
– Place the belt guard or shield back in position and secure it with the bolts.
– Tighten the bolts evenly to ensure a secure fit.
Step 6: Final checks and adjustments
– Reconnect the spark plug wire to the engine.
– Start the engine and check the belt’s tension and alignment. Adjust the tensioner pulley if necessary.
