783-06424A-0637 Deck Belt Cover Black Compatible with MTD/Craftsman/Troy-Bilt/Husky Lawn Mower 42" 46" Deck Replaces 783-06424A Mower Desk Parts 13AD775S059 13WX78TS090 24728902 247288842 (2 Pack)

What It Is

This is a set of two black plastic deck belt covers designed to shield the drive belt on 42" and 46" mower decks from debris and accidental contact. They’re intended for MTD, Craftsman, Troy-Bilt, and Husqvarna lawn tractors with side-discharge or mulching decks.

Fitment & Compatibility

Before buying, confirm your deck size (42" or 46") and the exact model number of your mower—this part fits specific MTD-based models like the 13AD775S059, 13WX78TS090, 24728902, and 247288842. It replaces OEM part 783-06424A. Measure the existing cover’s mounting hole spacing (typically 3.5–4 inches apart) and check that your deck has the two threaded studs or bolt holes near the belt path. Not compatible with zero-turn or walk-behind mowers.

Key Things to Know

• Material: Black plastic is durable but can crack if over-tightened during installation—hand-tighten only.
• Installation: Simple bolt-on job with no special tools; takes under 10 minutes per cover.
• Gotcha: Some users report the mounting holes don’t align perfectly on older decks—use a small file to enlarge holes if needed.
• Pack size: Two covers included, but most mowers only need one; you’ll have a spare for the other side or future replacement.

Should You Buy It

If your original belt cover is cracked, missing, or broken, this is a solid budget-friendly replacement. It’s ideal for DIY homeowners with common MTD/Craftsman/Troy-Bilt tractors who want a quick fix without paying OEM prices. Skip it if you need a metal cover for heavy-duty commercial use, or if your deck uses a non-standard mounting pattern.
