Exmark 1-403085-01 48 52 Inch Cover Plate Lazer Z 1-403085

What It Is

The Exmark 1-403085-01 is an OEM cover plate designed to seal the discharge opening on select Exmark Lazer Z zero-turn mowers with 48- or 52-inch decks. It prevents debris, grass clippings, and moisture from entering the deck housing when not in use.

Fitment & Compatibility

This plate fits Exmark Lazer Z models with 48-inch (e.g., LZ48) or 52-inch (e.g., LZ52) fabricated decks. Crucial check: Measure your deck’s discharge opening width—this plate is for decks with a 15.5-inch opening. It will not fit 60-inch or wider decks. Confirm your mower uses the pre-drilled mounting holes near the discharge chute; some older Lazer Z models may require drilling. OEM part number 1-403085-01—aftermarket versions exist but may lack exact hole alignment or gasket thickness.

Key Things to Know

• Construction: Heavy-duty steel with powder coating; resists rust but inspect for warping if buying used.
• Installation: Simple bolt-on—requires a 3/8-inch socket and 10 minutes. No cutting or welding.
• Common gotcha: The gasket (sold separately, Exmark 1-403086) is often missing from used plates. Without it, the plate rattles and leaks.
• Performance: Reduces grass buildup under the deck and protects the spindle area during storage or transport.

Should You Buy It

Yes, if you own a 48- or 52-inch Lazer Z and want to keep your deck clean and protected during storage or between cuts. It’s a straightforward OEM upgrade that beats rigging a tarp or leaving the opening exposed. Skip it for larger decks or if you only mulch—you won’t use the discharge opening.
