Exmark 116-6514 50 Inch Fabricated Mulching Kit

What It Is

This Exmark 116-6514 is a 50-inch fabricated steel mulching kit designed to convert Exmark zero-turn mowers from side discharge or bagging to a mulching setup. It replaces the standard discharge chute and baffles to recirculate clippings for finer cutting and lawn feeding.

Fitment & Compatibility

• Deck size: Only fits Exmark 50-inch fabricated decks (not stamped or 48/52/60-inch decks).
• Model check: Confirmed for Lazer Z, Lazer Z X-Series, and Lazer Z S-Series with 50-inch fabricated decks. Verify your deck part number begins with “50-xxxx” or consult your owner’s manual.
• OEM only: This is a genuine Exmark part—no aftermarket alternatives exist for this specific kit. Aftermarket “universal” kits won’t align with Exmark’s baffle mounting holes.
• Measure before buying: Check deck-to-ground clearance (mulching needs at least 3.5 inches) and ensure no existing side-discharge deflector interferes with the kit’s mounting brackets.

Key Things to Know

• Quality: Heavy fabricated steel with powder coat finish—holds up better than stamped kits under heavy use.
• Installation difficulty: Moderate. Requires removing the discharge chute, installing the mulching baffle, and swapping the blade (included). Expect 1–2 hours with basic hand tools.
• Common gotcha: The kit includes new mulching blades, but they’re standard OEM replacements. If you run with dull blades, mulching performance drops fast—plan to sharpen or replace them annually.
• Performance: Cuts fine in dry grass but struggles with wet, thick turf. You’ll need to slow ground speed and avoid tall grass to prevent clumping.

Should You Buy It

If you own an Exmark 50-inch fabricated deck and want OEM-grade mulching for regular lawn maintenance, this kit delivers durability and proper fit. Skip it if you often mow wet or overgrown grass—you’ll still need to bag or side-discharge for those conditions.
