Exmark 109-8073 Replacement Deck Belt 198.98 in - Heavy-Duty Aramid

In this review the Exmark 109-8073 replacement deck belt is evaluated for owners of ExMark 60' LAZER Z series mowers who need a heavy-duty, direct-fit replacement. The bottom line: this belt's precise 198.98 in circumference and 0.625 in width make it a straightforward swap for the OEM part numbers it replaces, and its Aramid cord construction is the single biggest reason to consider it if longevity and resistance to heat and abrasion matter to you.

Key Features

• Exact fit: 198.98 in length and 0.625 in width provide a precise circumference match for ExMark decks to ensure proper tension and routing.
• OEM compatibility: Direct replacement for ExMark part numbers 109-8073, 116-1985, and 135-5774, making installation straightforward for compatible models.
• Model coverage: Compatible with 60' LAZER Z Series, LAZER Z ADVANTAGE, and NEXT LAZER variants so owners of those decks can use one belt across multiple mower trims.
• Durable material: Built with high-strength Aramid cord to resist wear, heat, oil, and abrasion for extended service life under demanding conditions.
• Warranty support: Includes a 1-year warranty offering a free replacement or refund if the belt is defective within the period.

Who It's For

This belt is aimed at owners of ExMark 60' mowers in the LAZER Z family who want a direct OEM-replacement belt built from a tougher cord material. It fits Standard, AS, LZ-LP, E, S, X, Z, LAZER Z ADVANTAGE Standard and X, and NEXT LAZER ASX and Standard models, so it is particularly useful for fleet operators and homeowners who prefer a like-for-like part when servicing their decks.

Those who should look elsewhere include users with non-ExMark decks or different deck circumferences, and buyers who need an extended-life solution backed by a long-term track record-some customers reported early failures, so if absolute proven longevity is critical, consider verifying local shop options or alternative materials.
