109-8073 116-1985 Mower Deck Kevlar Belt for Exmark 60 Inch Decks Lazer Z AS E S X Series Zero Turn         

What It Is

This is an aftermarket Kevlar-reinforced drive belt for Exmark 60-inch mower decks, designed to transfer power from the engine or electric clutch to the blade spindles on Lazer Z AS, E, S, and X Series zero-turn mowers.

Fitment & Compatibility

Before buying, confirm your mower has a 60-inch fabricated deck and is a Lazer Z AS, E, S, or X Series model. This belt replaces OEM part numbers 109-8073 and 116-1985. Measure your current belt length (should be roughly 116.5 inches) and width (0.5 inches). It will not fit 48-inch or 52-inch decks, nor older Lazer Z models without “AS/E/S/X” in the name. Check your owner’s manual or existing belt part number to avoid mismatch.

Key Things to Know

• Kevlar construction improves durability over standard rubber belts, reducing stretch and breakage under heavy use.
• Installation is moderate difficulty—requires removing the deck or using a belt tensioner tool. A diagram of belt routing is essential (available in your manual or online).
• Common gotcha: This belt may run slightly tighter than OEM. If your spindles are worn or bearings are loose, it can cause premature wear or noise.
• Not a OEM part—while Kevlar adds strength, fitment tolerances can vary. Check for proper alignment after installation.

Should You Buy It

Buy this if you own a compatible Exmark 60-inch Lazer Z (AS/E/S/X Series) and want a tougher belt than standard OEM without paying dealer prices. Skip it if you prefer guaranteed OEM fitment or have a non-60-inch deck. Good value for heavy-duty residential or light commercial use.
