116-1985 109-8073 Lawn Mower Deck Belt 5/8" x 199" for Exmark 60 Inch Decks Lazer Z AS E S X Series Zero Turn

What It Is

This is a replacement deck belt (5/8 inch wide, 199 inches long) designed for Exmark zero-turn mowers with 60-inch cutting decks. It drives the blades on Lazer Z AS, E, S, and X Series models, and is a direct cross-reference for OEM part numbers 116-1985 and 109-8073.

Fitment & Compatibility

Before buying, verify three things: your deck width is exactly 60 inches (not 50 or 72), your mower model is an Exmark Lazer Z AS/E/S/X Series (not Quest or Turf Tracer), and your OEM part number matches 116-1985 or 109-8073. Measure your old belt’s length (end-to-end, not around pulleys) to confirm 199 inches. This is an aftermarket belt—while it claims to match OEM specs, tolerances can vary slightly. Check that your deck has two idler pulleys and a spring-loaded tensioner; some older Lazer Z models may use a different belt routing.

Key Things to Know

• Quality variance: At 3.5 stars with only 3 reviews, quality feedback is thin. Some aftermarket belts wear faster or stretch more than OEM. Expect 1–2 seasons of residential use, less for commercial.
• Installation difficulty: Moderate. You’ll need to remove the deck or at least the belt cover, release tension, and route the belt per your deck diagram. A spring tensioner tool (or a long screwdriver and patience) is helpful.
• Common gotcha: The 199-inch length is critical—too short won’t engage, too long slips. Double-check your old belt’s length; if it’s stretched, measure a new OEM belt for reference. Also, routing errors are common—snap a photo before removal.
• No warranty info listed: Most aftermarket belts carry a 30-day to 1-year limited warranty—verify before buying if you need coverage.

Should You Buy It

This belt is a budget-friendly option for homeowners or light commercial users who need a quick replacement for an Exmark Lazer Z 60-inch deck and are comfortable with basic mechanical work. If you mow daily or want guaranteed longevity, stick with an OEM Exmark belt (usually $10–15 more). For occasional use, this is a functional, cost-effective pick—just confirm fitment carefully.
