How to Install the Deck Belt of a Yard Pro Lawn Mower
- 1). Undo the single bolt holding the drive cover to the mower, using a socket wrench, and remove the drive cover. Undo the two bolts attaching the belt keeper to the mower housing and lift the belt keeper out.
- 2). Pull the spark plug boot off the top of the plug and push it to one side away from the spark plug.
- 3). Push down on the drive belt pulley and roll the belt out of the pulley groove while reaching underneath and turning the cutting blade.
- 4). Turn the mower on its side with the carburetor and air cleaner uppermost.
- 5). Jam a wood block between the mower blade and the mower housing.
- 6). Undo the blade-securing bolt by turning it counterclockwise with a socket wrench. Lift the blade off the shaft together with the bolt, lock washer and case-hardened plain washer.
- 7). Slide the worn drive belt off the crankshaft pulley and discard it.
- 8). Install a new belt by reversing the above operations.
