The Role of the Drive Belt

The drive belt connects the engine pulley to the transmission pulley. When the engine runs, the belt rotates, driving the transmission and, consequently, the wheels. Over time, the belt can wear down due to friction, heat, and exposure to the elements.

Common Signs of a Worn Drive Belt

• Slipping: The mower struggles to move, especially uphill.
• Squealing Noise: A high-pitched squeal indicates belt slippage.
• Cracks and Wear: Visible cracks, fraying, or missing chunks on the belt.
• Complete Breakage: The mower won't move at all.

Different Types of Drive Belts

Craftsman mowers use various types of drive belts, including V-belts and Kevlar belts. Kevlar belts are more durable and heat-resistant, making them a better choice for heavy use.

2. Identifying the Correct Drive Belt Diagram for Your Model

Locating Your Mower's Model Number

The model number is typically found on a sticker or plate located on the mower's frame, often under the seat or on the rear panel. It's essential to have this number handy when searching for the correct diagram and replacement belt.

Using the Model Number to Find the Diagram

1. Craftsman's Website: Visit the official Craftsman website and use the model number to access the parts diagram section.
2. Parts Retailers: Websites like Sears PartsDirect and MTD Parts offer diagrams for various Craftsman models.
3. Online Forums: Lawn mower forums can be a valuable resource for finding diagrams and advice from other owners.

Drive belt diagrams use symbols to represent different components, such as pulleys, idler pulleys, and the belt itself. Familiarize yourself with these symbols to interpret the diagram correctly.

• Solid Lines: Represent the belt's path.
• Circles: Indicate pulleys.
• Arrows: Show the direction of belt rotation.
