783-08547-0637 46" Deck Belt Cover Compatible with MTD 13AAA1KT066 13AL78KT066 247203744, for Cub Cadet XT1-LT46, XT1-LT46 FAB, XT2-LX46 - Black

What It Is

This is a 46-inch deck belt cover (OEM part 783-08547-0637) designed to shield the drive belt and pulleys under the cutting deck on certain MTD and Cub Cadet lawn tractors. It’s a direct-fit replacement for worn, cracked, or missing covers on models like the Cub Cadet XT1-LT46, XT1-LT46 FAB, and XT2-LX46.

Fitment & Compatibility

Before buying, confirm your mower has a 46-inch stamped or fabricated deck (not 42” or 54”). This cover fits MTD models 13AAA1KT066, 13AL78KT066, and 247203744, plus the Cub Cadet XT1-LT46 and XT2-LX46 series. It’s an OEM-equivalent part—matches dimensions and mounting holes of the original. No modifications needed if your deck is listed. Measure the existing cover’s length and hole spacing (approx. 46” wide) if unsure. Not compatible with older MTD decks or non-Cub Cadet brands without cross-referencing.

Key Things to Know

• Quality: Sturdy black plastic, resists UV and impacts better than thin aftermarket covers.
• Installation: Easy—remove two or three bolts (usually 5/16” or 8mm), swap covers, reinstall. No special tools.
• Gotcha: Check that your deck belt is correctly routed before installing—this cover won’t fix a misaligned belt.
• Gotcha: Some users report the cover may need slight trimming if your deck has aftermarket pulleys or belt guides. Inspect clearance after mounting.

Should You Buy It

If you own a Cub Cadet XT1 or XT2 with a 46” deck and your original cover is broken, missing, or cracking, this is a direct, affordable replacement. It’s also a good upgrade if your current cover rattles or lets debris into the belt area. Not needed if your cover is intact and secure.
