Exmark 116-3519 Bag and Frame Lazer Z HP Ultra Vac Bagger 1-654390 116-0753

What It Is

This is the OEM Exmark Ultra Vac bagger assembly (bag and frame) designed for Lazer Z HP zero-turn mowers. It collects clippings during high-volume cutting, ideal for commercial landscapers or large residential properties.

Fitment & Compatibility

• Exact fit for: Exmark Lazer Z HP models with 60-inch or 72-inch decks (check your deck serial number).
• OEM part number: 116-3519 (replaces 1-654390 and 116-0753).
• Not compatible with: Lazer Z X-Series, Lazer Z S-Series, or other Exmark models without Ultra Vac system pre-installed.
• Before buying: Verify your deck has the Ultra Vac mounting brackets (two horizontal bars under the deck). Measure deck width—if it’s 48-inch or 52-inch, this unit won’t fit. Confirm your mower has the factory discharge chute and belt drive for the vacuum system.

Key Things to Know

• Build quality: Heavy-duty steel frame with reinforced fabric bags; rated for commercial use, but bags can tear if overloaded with wet grass.
• Installation: Moderate difficulty—requires removing the existing discharge deflector and attaching the frame to the deck brackets. Expect 45-60 minutes with basic hand tools.
• Gotcha: The bag capacity (approx. 8 bushels) fills quickly on tall, thick grass—empty frequently to avoid clogging the vacuum system.
• Maintenance: Clean the chute and bag screens after each use to prevent grass buildup and reduced airflow.

Should You Buy It

If you own an Exmark Lazer Z HP with a 60- or 72-inch deck and need OEM-grade durability for daily commercial mowing, this is the right bagger. It’s a direct fit, but verify your deck has the Ultra Vac mounting brackets first—if not, you’ll need the full conversion kit. Skip it for smaller decks or occasional home use.
