CUB CADET 490-501-F061 Transmission Drive Belt LE XT2 XT1 ST54 SLX54 SLX50 LX54 CMXGZAM501061 954-05027B 954-05027A

What It Is

This is the OEM transmission drive belt for select Cub Cadet XT1, XT2, and LX/SLX lawn tractors. It transfers power from the engine to the transmission, enabling forward/reverse motion—not the mower deck belt.

Fitment & Compatibility

Before buying, verify your tractor’s model and deck size:

• Fits: Cub Cadet XT1 (LT42, LT46, etc.), XT2 (LX42, LX46, etc.), ST54, SLX50, SLX54, LX54, and CMXGZAM501061 series.
• Cross-references: Replaces OEM part numbers 954-05027B, 954-05027A, and 490-501-F061.
• Measure your old belt: This belt is 1/2" wide x 96.5" long (approximately). If your belt is a different length or width, it won’t fit.
• Check your machine’s serial number: Some early-year XT1/XT2 models used a different belt. Use Cub Cadet’s online parts lookup with your mower’s model and serial number to confirm.

Key Things to Know

• OEM quality: This is a genuine Cub Cadet belt, not an aftermarket knockoff. Expect better durability and exact fit versus generic belts.
• Installation difficulty: Moderate. You’ll need to remove the mower deck and possibly the transmission pulley cover. A belt routing diagram is usually printed on the mower frame or in the manual.
• Common gotcha: Don’t confuse this with the deck drive belt. The deck belt is shorter and wider. This belt is exclusively for transmission drive.
• Lubrication tip: While installing, check the transmission pulley and idler for wear or debris. A seized idler will quickly ruin a new belt.

Should You Buy It

Yes, if you own a compatible Cub Cadet XT1/XT2 or LX/SLX series and need a direct OEM replacement. It’s the correct spec, well-reviewed, and avoids fitment headaches of generic belts. Skip it if your tractor uses a different belt length or you’re replacing a deck belt.
